Crypto lending means letting others borrow your coins in exchange for interest. With stablecoin lending, the coins are dollar-pegged tokens like USDT and USDC, so your balance stays roughly stable in dollar terms while it earns. Borrowers pay interest because they want to use stablecoins, usually to trade, to leverage other positions or to get cash without selling their crypto. Lenders receive most of that interest.
It's one of the simplest ways to earn on crypto you'd otherwise leave idle, but it carries risks that are different from staking. This guide explains how stablecoin lending works, the two main models, what it typically pays and what can go wrong. In Virtex Wallet, you can lend USDT and USDC in both custodial and non-custodial mode. This is general information, not financial advice.
How does crypto lending work?
The basic flow is the same everywhere:
- Lenders deposit stablecoins into a lending pool.
- Borrowers take stablecoins out of the pool. In most crypto lending, they must first lock up collateral worth more than they borrow, for example $150 of ETH to borrow $100 of USDC.
- Borrowers pay interest while the loan is open.
- Lenders earn that interest, minus any fee the platform takes.
- If a borrower's collateral falls too far in value, it is sold (liquidated) to repay the loan, so lenders are protected from that borrower defaulting.
This over-collateralisation is the key safety feature. Lenders aren't relying on a borrower's promise to pay back; they're relying on collateral being sold in time if prices move.
Where does the interest come from?
From borrowers. That matters, because it tells you how rates behave:
- When demand to borrow is high (for example, in busy markets), rates rise.
- When demand is low, rates fall.
Most lending pools set the rate automatically using utilisation: the share of the pool currently borrowed. High utilisation means higher rates for lenders, but also less spare liquidity for lenders who want to withdraw.
Typical stablecoin lending rates have been roughly 2% to 8% a year, occasionally higher for short periods. Rates change constantly; check the live rate before you lend.
Custodial vs non-custodial lending
There are two ways to lend crypto, and the difference is who holds your coins.
| Non-custodial lending | Custodial lending | |
|---|---|---|
| Who holds the coins | A smart contract; you control the position with your own keys | The provider holds them on your behalf |
| How it works | Your wallet supplies stablecoins to an on-chain lending pool | The provider deploys pooled funds and credits you interest |
| Can you verify it? | Yes, on a block explorer | Through the provider's account view |
| Main risk | Smart-contract bugs or exploits | Provider failure, mismanagement or frozen withdrawals |
| Withdrawals | Whenever the pool has free liquidity | Per the provider's terms |
Non-custodial lending keeps you in control: only your keys can withdraw, and the rules are written in public code. The trade-off is that code can have bugs, and you're responsible for your seed phrase.
Custodial lending is simpler: deposit, earn, withdraw, with account recovery if you lose access. The trade-off is that you're trusting the provider. Several large custodial lending platforms collapsed in 2022 and froze customer withdrawals, which is why it's worth understanding this model before you use it. The same idea is covered for staking in custodial vs non-custodial staking.
What are the risks of crypto lending?
No lending is risk-free. The main risks:
- Smart-contract risk. A bug or exploit in a lending protocol could cause losses.
- Custodial or counterparty risk. If a provider holds your coins, you depend on its solvency and honesty.
- Stablecoin depeg risk. USDT and USDC aim to stay at $1, but a stablecoin can briefly trade below its peg, or worse if its reserves fail.
- Liquidity risk. If a pool is almost fully borrowed, you may have to wait for borrowers to repay or new lenders to arrive before you can withdraw.
- Liquidation shortfalls. In extreme crashes, collateral may not sell fast enough to fully cover a loan, leaving a pool short.
- Rate risk. Interest rates can drop at any time.
- Regulatory risk. Rules for crypto lending differ by country and keep changing.
How to reduce these risks: lend only amounts you can afford to have tied up, prefer long-running systems, understand who holds your coins, and spread funds if you lend a large amount.
Crypto lending vs staking: what's the difference?
| Staking | Stablecoin lending | |
|---|---|---|
| What you use | Proof-of-stake coins (SOL, ETH, TRX, BNB) | Stablecoins (USDT, USDC) |
| Who pays you | The blockchain network | Borrowers |
| Price exposure | Yes, rewards and principal move with the coin | Low, balances are dollar-pegged |
| Typical rate* | ~1–8% depending on coin | ~2–8% depending on demand |
| Main risk | Coin price drops | Platform, contract and depeg risk |
| Getting coins back | Network unstaking period | Pool liquidity or provider terms |
*Rough ranges; rates change.
Staking grows a coin you want to hold. Lending earns on dollar balances. The full comparison is in crypto staking vs lending, and the basics of staking are in what is crypto staking. If you hold SOL or TRX, see how to stake Solana or how to stake TRX.
Why can't you just stake stablecoins?
Staking is how proof-of-stake blockchains are secured. USDT and USDC are tokens that live on those blockchains, not blockchains themselves, so there's nothing for them to secure. Any "USDT staking" product is really lending or a promotion. We explain this in can you stake USDT?
How to lend USDT or USDC in Virtex Wallet
- Install Virtex Wallet from Google Play.
- Choose non-custodial mode (lend from your own keys) or custodial mode (Virtex manages it for you). (Custodial mode isn't available in the EEA, the UK or the USA.)
- Add USDT or USDC on a supported network, plus a little of that network's coin for fees in non-custodial mode.
- Open the stablecoin and choose the lending option.
- Review the current rate, any fee and how withdrawals work, then confirm.

Common questions
Is crypto lending safe?
It carries real risks, including smart-contract bugs, provider failure and stablecoin depegs. Over-collateralised lending reduces borrower-default risk, but nothing makes lending risk-free.
How much can you earn lending stablecoins?
Rates have typically been in the low-to-mid single digits per year and change with borrowing demand. Check the current rate before you lend.
Can I withdraw my stablecoins at any time?
Usually, as long as the pool has enough unborrowed liquidity (non-custodial) or under the provider's terms (custodial). Very high borrowing demand can delay withdrawals.
Who borrows stablecoins?
Mostly traders and crypto holders who want dollars without selling their coins. They lock up collateral worth more than the loan.
Is lending interest taxable?
In many countries, interest from crypto lending is taxed as income. See are staking rewards taxable for the general rules. This is not tax advice.
