Perfolio is a gold-backed lending platform. You buy gold (XAUT, where each token equals exactly 1 ounce of real physical gold stored in Swiss vaults), then borrow digital dollars (USDT, each worth exactly $1, convertible to your local currency) against your gold. No credit checks needed. No monthly EMI payments. No repayment deadlines. Your gold stays yours throughout. When you repay the loan, you get your gold back. It works like a modern digital gold pawn shop, but without the middleman, the paperwork, or the fees.

Gold (XAUT) is a digital gold token issued by Tether (the same company behind USDT stablecoins). Each gold token (XAUT) represents exactly 1 troy ounce of real physical gold, stored in LBMA-certified vaults in Switzerland. The gold reserves are independently audited every quarter by BDO Italia. Unlike gold ETFs, gold (XAUT) is redeemable for actual physical gold bars. Think of it as a digital certificate of ownership for gold in a vault: you own the gold, XAUT is your proof.

How does borrowing work?

Borrowing on Perfolio works in four simple steps. First, you buy gold (XAUT tokens) through the Perfolio app using your bank transfer or existing digital dollars (USDT). Second, you deposit your gold (XAUT) into the lending vault; think of this as locking your gold as security. Third, you receive digital dollars (USDT, worth $1 each) instantly, up to 77% of your gold's value. Fourth, you convert those digital dollars to your local currency (Indian Rupees, UAE Dirhams, Euros, etc.) and withdraw to your bank account. Your gold remains safely locked in the vault throughout. When you repay the loan, your gold is returned to you.

What interest rate will I pay?

Perfolio charges a variable interest rate starting from approximately 3% per year (APR, or Annual Percentage Rate). This means if you borrow $1,000 for a full year, you would pay about $30 in interest. The rate is not fixed; it goes up or down based on supply and demand in the lending market. You can see your current rate at any time in your Perfolio dashboard. There are no fixed monthly payments; interest accrues daily on whatever amount you have borrowed.

Are there repayment deadlines?

No. There are no repayment deadlines, no EMIs (equated monthly installments), and no fixed repayment schedule. You repay on your own terms, partially or fully, whenever you choose. You could repay after one week, one month, or one year. The only ongoing cost is interest, which accrues daily on your outstanding loan balance. Your gold collateral is returned to you as soon as the full loan amount plus accrued interest is repaid.

Where is my gold stored?

Your gold (XAUT tokens) represents physical gold bars stored in LBMA-certified (London Bullion Market Association) vaults in Switzerland. These are professional-grade precious metals storage facilities, the same standard used by central banks and institutional investors. The gold is fully insured. Tether, the issuer of XAUT, publishes independently audited reserve reports every quarter, conducted by BDO Italia, confirming that every gold token (XAUT) in circulation is backed by a real ounce of physical gold.

What fees does Perfolio charge?

Perfolio charges interest only on the amount you have borrowed, nothing else. There are no origination fees (fees for creating the loan), no account maintenance fees, no deposit fees, no withdrawal fees, and no hidden charges of any kind. You pay interest daily on your outstanding loan balance at the variable market rate, which starts from approximately 3% APR. If you borrow $1,000 for 30 days at 3% APR, you pay roughly $2.50 in total interest.

Is the lending protocol secure?

Perfolio uses an independently audited smart contract as its lending infrastructure. It is a non-custodial lending protocol deployed on Ethereum, one of the most widely used and tested blockchain networks in the world. Non-custodial means no single company (including Perfolio) can access or freeze your funds. The protocol has been independently audited by multiple leading security firms and handles billions of dollars in assets. All transactions are recorded publicly on the Ethereum blockchain, meaning you can verify every deposit, loan, and repayment yourself.

Is Perfolio a cryptocurrency app?

No. Perfolio is a gold lending platform that uses blockchain technology under the hood, similar to how Uber uses GPS technology, but you don't need to understand GPS to take a ride. You interact with gold and money, not with cryptocurrency. The blockchain ensures your transactions are transparent, secure, and instant.

What is USDT and how do I use it?

USDT (Tether USD) is a digital currency worth exactly $1. Think of it as digital dollars that you can send anywhere instantly. When you borrow on Perfolio, you receive USDT. You can then convert USDT to your local currency (Indian Rupees, UAE Dirhams, Euros, British Pounds, and more) through Perfolio's licensed payment provider and withdraw to your bank account.

What does 'digital gold' mean?

Digital gold means you own a token that represents real physical gold stored in a vault. Instead of keeping gold bars at home or in a bank locker, you hold a digital certificate (XAUT token) that proves you own that gold. The advantage: you can buy fractional amounts (as little as $10 worth), trade 24/7, and use your gold as collateral for instant loans. These are things you can't do with physical gold.

How does the lending technology work?

Perfolio's loans are powered by an audited smart contract, which is automated banking software that runs on the Ethereum blockchain. Instead of a bank officer processing your loan (which takes days and involves paperwork), the smart contract processes it in seconds with no human intervention. The protocol has been independently audited by multiple leading security firms and handles billions of dollars in loans.

What is LTV (Loan-to-Value)?

LTV stands for Loan-to-Value ratio. It's how much you can borrow relative to your gold's value. Perfolio allows up to 77% LTV. Example: if your gold is worth $10,000, you can borrow up to $7,700. The remaining $2,300 acts as a safety buffer in case gold price drops. A lower LTV means a safer position.

What happens if gold price drops while I have a loan?

If gold price drops significantly, your loan may become under-collateralized (meaning your gold is no longer worth enough to back your loan). In this case, the lending protocol may automatically sell some of your gold to repay part of the loan. This is called liquidation. Perfolio shows your 'health factor' in real-time so you can take action before this happens: either add more gold collateral or repay part of your loan.

Do I need to understand blockchain or crypto to use Perfolio?

Not at all. Perfolio is designed for people who want to use gold as a financial tool, not for crypto experts. You buy gold, you borrow money, you repay when you want. The blockchain technology works in the background to make everything faster, cheaper, and more transparent, but you never need to interact with it directly.

XAUT Lending: The Complete Guide

XAUT lending lets you deposit gold (XAUT) into a automated lending contract (smart contract) and borrow digital dollars (USDT) against it without selling. On Perfolio, you can borrow up to 77% of your gold's value at a typical annual rate under 5%, and the protocol is fully non-custodial, meaning only your wallet can ever withdraw your collateral. Your gold stays on-chain, audited, and always yours.

What Is XAUT? A Primer on Tether Gold

XAUT is Tether's gold-backed digital token. Each token represents exactly one troy ounce of physical gold held inside LBMA-certified Swiss vaults. You can think of it as a bearer certificate for gold that lives on a blockchain instead of inside a safety deposit box.

Tether issues XAUT primarily on Ethereum, with a secondary issuance on Tron. Every token is backed one-to-one by a segregated, individually identified gold bar sitting in Switzerland. BDO Italia, one of the world's largest independent auditing firms, publishes quarterly attestations confirming the reserve matches the outstanding token supply. As of early 2026, XAUT represents hundreds of millions of dollars in gold held on behalf of token holders worldwide.

One of the most important things to understand about XAUT is what it does not cost you. Unlike physically storing gold, holding XAUT carries zero storage fees. No annual vault charge. No insurance premium passed on to you. The only cost of ownership is the gas you pay when you move it on-chain, and even that is minimal on modern Ethereum.

Why Is XAUT the Best Collateral for a Digital Gold Loan?

Not all gold is equally useful as collateral. Physical gold bars locked in your basement cannot be pledged to a lending protocol at midnight on a Sunday. XAUT can. The properties that make it ideal are:

24/7 availability. XAUT moves on Ethereum, which settles every 12 seconds, around the clock. There are no banking hours, no holiday closures.
Divisibility. You can deposit a fraction of an ounce. Perfolio accepts deposits as small as $10 worth of gold, making the product accessible to everyone, not just large holders.
No storage friction. Pledging XAUT as collateral adds no incremental cost. The gold was already in a vault for free. You are simply giving the protocol temporary permission to hold it while your loan is open.
On-chain transparency. Every deposit, every liquidation threshold, and every repayment is recorded publicly on Ethereum and verifiable by anyone. There is no hidden ledger.
Audited backing. BDO Italia's quarterly audits provide external verification that each token is matched by real gold. This is materially stronger than many synthetic gold products.
Ethereum-native composability. Because XAUT is an ERC-20 token, it plugs directly into smart contract lending infrastructure without bridges, wrapping, or trusted intermediaries.

Globally, the tokenised real-world asset market surpassed $10 billion in 2025. Gold-backed tokens account for a meaningful share of that figure, with XAUT and PAXG together representing the bulk of circulating supply. The trend reflects a broader institutional recognition that on-chain gold is a superior form of collateral compared to the paper gold products that dominate traditional finance.

How Does XAUT Lending Work on Perfolio?

Mobile DeFi interface for gold lending — XAUT lending operates entirely on-chain, accessible from any device, anywhere, at any time.

The Perfolio borrowing flow is deliberately straightforward. Here is exactly what happens from deposit to repayment:

Connect your wallet. Perfolio is non-custodial. You connect a self-custody wallet (MetaMask, Coinbase Wallet, or any WalletConnect-compatible wallet). Perfolio never takes possession of your keys.
Deposit gold (XAUT). You approve a transfer of XAUT into the Perfolio vault smart contract. The contract is independently audited. Only your wallet address has the permission to withdraw the collateral back.
Receive your USDT. The protocol calculates your available credit line at up to 77% of your gold's current value and sends digital dollars (USDT) directly to your wallet. No credit check. No paperwork. No waiting period.
Use the funds. You can do whatever you like with the USDT. Convert to fiat through any exchange, use it for business expenses, or deploy it elsewhere in DeFi.
Repay at any time. There is no fixed repayment schedule. You repay principal plus accrued interest whenever it suits you. Interest accrues daily, so the longer you hold the loan open, the more you owe, but there is no penalty for paying early.
Reclaim your gold. The moment you repay in full, the contract releases your XAUT collateral back to your wallet. The entire cycle can take less than five minutes.

Because every step is governed by an audited smart contract, there is no human counterparty who can freeze your withdrawal, delay your repayment, or change the rules mid-loan. The Perfolio Borrowing Vault documentation explains the contract logic in detail for technically minded readers.

XAUT vs PAXG vs Physical Gold as Collateral

XAUT is not the only gold-backed token in the market. PAXG, issued by Paxos, competes directly for the same use case. Physical gold is also worth comparing, since many prospective borrowers hold it and wonder whether tokenising their holdings makes sense. The table below summarises the key differences:

Attribute	XAUT (Tether Gold)	PAXG (Paxos Gold)	Physical Gold
Issuer	Tether	Paxos	N/A
Custodian	LBMA-certified Swiss vaults	Brink's vaults (USA)	Home safe, bank vault, or private storage
Audit frequency	Quarterly (BDO Italia)	Monthly (Withum)	None (self-held)
Annual storage fee	None	0.02% per year above 430 oz	Varies (0.1%+ for professional storage)
Primary network	Ethereum (ERC-20)	Ethereum (ERC-20)	Not applicable
24/7 collateral deposit	Yes	Yes	No
Minimum deposit on Perfolio	$10	N/A (not supported)	N/A (not applicable)
Use as DeFi collateral	Yes (native ERC-20)	Yes (native ERC-20)	No (requires tokenisation first)
Redemption for physical bar	Yes (minimum lots apply)	Yes (minimum lots apply)	Already physical

How Are APR and Interest Calculated on an XAUT Loan?

Perfolio's interest rate is variable. It is set by a supply-and-demand algorithm: when more borrowers want USDT than the protocol's liquidity pool can supply, the rate rises to attract more lenders; when demand is low, the rate falls. The typical rate hovers under 5% APR, with a practical range of roughly 2% to 8% depending on market conditions.

Interest accrues daily, not monthly or annually. On a $7,700 loan at 3% APR, the daily accrual works out to approximately $0.63 per day. There is no origination fee, no early repayment penalty, and no annual account fee. The only cost you pay is the daily interest for however many days you hold the loan open.

Because the rate is variable, it can shift after you open your loan. If you opened at 3% and market conditions push it to 5%, your next day's accrual increases accordingly. Perfolio displays the current rate in real time on the XAUT Loan page so you can monitor it at any time. Most borrowers who use Perfolio for short-to-medium term liquidity needs (days to a few months) find the rate far cheaper than credit cards or unsecured personal loans, which routinely charge 15% to 25% APR.

What Is the LTV on an XAUT Loan, and How Does It Work?

Loan-to-Value (LTV) is the ratio of your outstanding loan to the current value of your collateral. Perfolio caps LTV at 77%, which is among the most generous in the digital gold lending market.

Here is a concrete example. You deposit $10,000 worth of XAUT. Your maximum available borrow is $7,700 (77% of $10,000). If gold's price rises 10%, your collateral is now worth $11,000, and your health factor improves because the same $7,700 loan now represents only 70% LTV. If gold's price falls, your LTV climbs toward the liquidation threshold.

Your loan's health factor is a real-time indicator of how far you are from liquidation. A health factor above 1.0 means your position is safe. As your LTV approaches the liquidation threshold, the health factor approaches 1.0. You can improve your health factor at any time by either repaying part of your loan (reducing the numerator) or depositing additional XAUT collateral (increasing the denominator).

Perfolio sends wallet-level alerts as your health factor declines, giving you time to act before any automated liquidation occurs.

What Happens If Gold's Price Falls? Understanding Liquidation

If gold's price drops sharply and your LTV crosses the liquidation threshold, the Perfolio smart contract initiates a partial liquidation to bring the position back into a healthy range. This is entirely automatic. No human decision is involved.

In a liquidation event, the protocol sells a portion of your XAUT collateral on the open market, uses the proceeds to repay the excess loan balance, and returns any remaining collateral to your wallet. You do not lose everything. The liquidation is sized to restore your LTV to a safe level, not to close your entire position.

The best way to avoid liquidation is to borrow conservatively. If you borrow only 50% to 60% of your collateral's value rather than the full 77%, gold would need to fall 35% to 40% in a very short window before your position is at risk. Over the past decade, gold has shown brief drawdowns of that magnitude only in exceptional circumstances. Borrowing below the maximum LTV is the single most effective risk management tool available to you.

Perfolio vs Nexo vs CoinRabbit for XAUT Lending

If you are comparing platforms before choosing where to borrow against gold (XAUT), the differences between the main options matter significantly. The table below focuses on the attributes that most borrowers care about:

Attribute	Perfolio	Nexo	CoinRabbit
XAUT as collateral	Yes	Yes	No (support discontinued, page 404)
Custody model	Non-custodial (your keys, your gold)	Custodial (Nexo holds assets)	Custodial
KYC required	No (wallet-based)	Yes (mandatory)	Yes
Typical APR range	~3% (2–8% variable)	2.9–13.9% (tier-dependent)	N/A
Max LTV	77%	Up to 50% on crypto (varies by asset)	N/A
Minimum deposit	$10	Varies by asset and tier	N/A
Loan currency	USDT	USDT, USDC, fiat	N/A
Smart contract audited	Yes	No (centralised backend)	N/A
Early repayment penalty	None	None (standard plan)	N/A

The most important distinction is custody. When you use Nexo, you transfer your XAUT into Nexo's custodial wallets. If Nexo faces regulatory action, insolvency, or a security breach, your gold is at risk. With Perfolio, your XAUT is held inside an audited smart contract that is programmatically controlled; no Perfolio employee can access or move your collateral. For a detailed head-to-head analysis, see our Perfolio vs Crypto Lending Platforms comparison.

What Can You Do With Borrowed USDT?

The USDT you receive is yours to spend however you choose. Here are the most common use cases Perfolio borrowers report:

Compounding Gold Exposure

Borrow against existing XAUT, convert the USDT back into more XAUT, and deposit that as additional collateral. This creates leveraged gold exposure without triggering a taxable disposal event in most jurisdictions. You maintain upside if gold rises while paying only the under-5% APR cost of carry.

Avoiding Capital Gains Tax

In most jurisdictions, selling gold triggers a capital gains tax event. Borrowing against it does not. If your XAUT has appreciated significantly, borrowing lets you access liquidity without crystallising the gain. Consult a tax adviser to confirm the treatment in your specific jurisdiction before relying on this strategy.

Business Capital

If you hold gold as a long-term store of value but need short-term cash for a business opportunity, a 90-day XAUT loan at under 5% APR is dramatically cheaper than a merchant cash advance, a business line of credit at 8% to 15%, or an invoice factoring arrangement. You keep the gold, fund the opportunity, and repay when the business generates revenue.

Real Estate Down Payments

Converting USDT to fiat takes minutes via any major exchange. Borrowers who want to make a real estate down payment without liquidating their gold portfolio use this route to access liquid capital quickly while retaining their long-term gold position.

Bridge Financing

Waiting on a payment, a settlement, or a salary disbursement? An XAUT loan at $10 minimum deposit gives you instant bridge financing with no approval process. Repay the moment the expected cash arrives.

How to Start: A Step-by-Step Perfolio Walkthrough

Getting your first XAUT loan takes less than five minutes if you already hold XAUT in a self-custody wallet. Here is the exact process:

Acquire XAUT if you don't already hold it. Buy XAUT on Kraken, Bitfinex, Uniswap, or any major exchange that lists it. Transfer it to a self-custody wallet such as MetaMask or Coinbase Wallet.
Navigate to perfolio.ai and connect your wallet. Click "Connect Wallet" and approve the connection in your wallet app. Perfolio supports all WalletConnect-compatible wallets.
Open the Borrow page. Select XAUT as your collateral asset. Enter how much XAUT you want to deposit. The interface shows you your maximum borrow amount in real time.
Approve the XAUT transfer. Your wallet will prompt you to approve the contract to spend your XAUT. This is a standard ERC-20 approval. Confirm it.
Set your borrow amount. Enter how much USDT you want to borrow, up to the displayed maximum. We recommend borrowing 50% to 60% of your maximum to maintain a comfortable health buffer.
Confirm the transaction. Your wallet will prompt you to confirm the borrow transaction. Once confirmed on-chain (typically under 30 seconds), USDT lands in your wallet.
Monitor your health factor. Log back into Perfolio any time to check your LTV, health factor, and accrued interest. Repay partially or fully whenever you're ready.

Frequently Asked Questions About XAUT Lending

What is XAUT lending?

XAUT lending is the practice of using gold (XAUT) tokens as collateral to borrow digital dollars (USDT) without selling the gold. You deposit XAUT into an audited smart contract, receive USDT instantly, and reclaim your XAUT when you repay. On Perfolio, the process is non-custodial, meaning only your wallet can ever withdraw the collateral.

Is XAUT lending safe?

Safety depends on two factors: the protocol's smart contract security and your own position management. Perfolio's vault contracts are independently audited. On the position side, the main risk is liquidation if gold's price falls and your LTV crosses the threshold. Borrowing at 50% to 60% LTV rather than the maximum 77% gives you a substantial buffer against price drops. You should also only use funds you can afford to leave locked as collateral for the duration of the loan.

What is the interest rate on an XAUT loan at Perfolio?

Perfolio charges a variable rate driven by supply and demand in the USDT lending pool. The typical rate is under 5% APR, with a range of approximately 2% to 8% depending on market conditions. There is no origination fee and no early repayment penalty. Interest accrues daily on the outstanding principal.

How much can I borrow against XAUT?

Perfolio's maximum Loan-to-Value ratio is 77%. On a $10,000 XAUT deposit, you can borrow up to $7,700. The minimum deposit is $10, so you can access a small loan even if you only hold a fraction of an ounce of gold. Your available credit line updates in real time as gold's price moves.

What happens to my XAUT while the loan is open?

Your XAUT sits inside the Perfolio vault smart contract on Ethereum. Perfolio staff cannot access it, move it, or lend it to a third party. The contract's code is public and audited. Your collateral is released the moment you repay in full. If you are partially liquidated, the portion of XAUT sold is used to reduce your loan balance, and the remainder stays locked as collateral.

Does borrowing against XAUT trigger a taxable event?

In most jurisdictions, taking a loan secured by an asset is not a disposal and therefore does not trigger capital gains tax. This is one of the key reasons borrowers prefer lending over selling. However, tax treatment varies by country and individual circumstances. You should consult a qualified tax adviser before relying on this treatment in your specific situation.

How is Perfolio different from Nexo for XAUT loans?

The fundamental difference is custody. Nexo is a centralised, custodial platform: when you deposit XAUT, Nexo holds it on your behalf, and you are exposed to Nexo's counterparty risk. Perfolio is non-custodial: your XAUT is locked in an audited smart contract that only your wallet address can withdraw from. Perfolio also does not require KYC, while Nexo mandates identity verification. Nexo's APR ranges from 2.9% to 13.9% depending on your tier; Perfolio's typical rate is under 5% with no tier requirements.

Can I use XAUT as collateral on DeFi protocols other than Perfolio?

Because XAUT is a standard ERC-20 token, it is technically compatible with any DeFi protocol that whitelists it as collateral. However, not all protocols support it. Perfolio is purpose-built for gold-backed lending and offers the highest LTV for XAUT currently available (77%). Always verify a protocol's audit status and liquidation parameters before depositing collateral anywhere.
