Whether you can earn interest on Bitcoin depends on who holds your BTC while it earns. Every Bitcoin interest account, lending pool, and staking product relies on a third party to put your coins to work.
This guide covers five ways to earn Bitcoin yield and where the interest comes from. It also covers counterparty risk and smart contract risk.

Can you earn interest on Bitcoin?
Yes, you can earn interest on Bitcoin, but lending your BTC usually means someone else puts it to work. The platform may wrap your Bitcoin and use it as collateral in decentralized finance (DeFi), or reuse it through a similar mechanism.
Wrapped Bitcoin is a token on another blockchain that represents BTC held in reserve. One wrapped token’s own documentation says approved institutions mint tokens against custodied BTC. Before you lend, find out whether the product wraps, pledges, or simply holds your coins, because lending means your Bitcoin leaves your direct control.
Ways to earn interest on Bitcoin
Five routes pay interest or yield on Bitcoin, and they differ mainly in who controls your BTC while it earns.
Lending platforms
Lending platforms take your BTC on deposit, lend it to borrowers, and pay you interest, a model known as custodial lending. Accounts built on it are often marketed as Bitcoin interest accounts. In 2022, the SEC charged one such lender over unregistered interest accounts. The platform holds your keys and sets the rate, so your return depends on the company staying solvent.
Custodial lending suits holders who want a savings-style product and accept counterparty risk.
Native Bitcoin lending
Native Bitcoin lending means earning on the Bitcoin network itself, without wrapping your BTC or moving it to another blockchain. The Bitcoin protocol pays no interest, so supplying liquidity on the Lightning Network is the only native route and the closest thing to interest, paying routing or channel-lease fees. We describe Lightning lending based on our own understanding and experience of this market.
An emerging category of Lightning pools may use BTC and stablecoins issued on the Bitcoin network. The goal is to recreate DeFi-like dynamics while staying on Bitcoin infrastructure, and Kaleidoswap is one platform working on this. Its documentation describes a quote-based exchange where market makers earn the spread plus routing fees, and says outside market makers join from 2027.
Native Bitcoin lending suits holders who want to stay off other blockchains and accept an emerging ecosystem.
DeFi lending pools
A DeFi lending pool is a smart contract that collects deposits and lends them to borrowers at a rate set by supply and demand. You can supply wrapped BTC, such as WBTC, to a lending protocol like Aave and earn a variable rate that moves with borrowing demand.
DeFi lending pools suit holders who are comfortable with wrapped BTC, self-managed wallets, and smart contract risk. Chainalysis’ analysis of cross-chain bridge theft found bridge attacks made up 69% of funds stolen through early August 2022.
Staking and restaking
Bitcoin itself can’t be staked: it runs on proof-of-work, where miners secure the network, not staked coins. Products labeled “Bitcoin staking” are third-party arrangements that lock your BTC in a protocol to help secure another proof-of-stake network in exchange for rewards. Babylon, for example, locks your BTC with a Bitcoin timelock, but the staking runs on separate proof-of-stake chains, not on Bitcoin, so it isn’t Bitcoin staking whatever the label.
Bitcoin restaking reuses already-staked BTC, or a tokenized receipt for it, to secure further networks or services. Each added layer adds smart contract risk. On Ethereum, each restaked application adds its own slashing conditions, which are penalties that destroy part of the stake, and withdrawals can face additional delays.
Staking and restaking suit technically confident holders who accept newer protocols and rewards that may arrive in another token.
Liquidity pools
A liquidity pool is a smart contract that holds paired tokens for traders to swap against. Providers deposit both sides, such as a wrapped BTC token and a stablecoin, and earn a share of the trading fees.
A pool can end up worth less than simply holding the same tokens when their prices diverge, a loss known as impermanent loss. Liquidity pools suit experienced DeFi users who accept that trade-off.
How earning interest on Bitcoin works
Earning interest on Bitcoin works by lending your BTC to someone who pays to use it. The platform or protocol deploys your coins and passes part of the return back to you. We describe these mechanics based on our own understanding and experience of how this market operates.
The return comes from three sources:
- Borrower interest: borrowers pay interest for the use of your BTC, and the platform keeps a spread before paying you.
- Trading and routing fees: liquidity pools and Lightning channels pay providers a share of the fees on the swaps and payments they enable.
- Staking rewards: protocols pay rewards to BTC locked to secure other networks.
A platform can only pay you interest if it earns that interest somewhere, so it has to put your BTC to work. That means lending it out, deploying it in DeFi, or pledging it as collateral. When a platform pledges customer deposits for its own trading or borrowing, the practice is called rehypothecation.
The advertised APY is the net rate after the platform’s cut. It says nothing about where your BTC was deployed.
Risks of lending your Bitcoin for interest
The 2022 collapses of Celsius, BlockFi, Voyager, and Genesis show these risks in practice: each suspended withdrawals in 2022 and later filed for bankruptcy, Genesis last in January 2023.
- Counterparty risk: the platform that holds or borrows your BTC can fail to return it.
- Bankruptcy risk: on January 4, 2023, a US court ruled that Celsius Earn deposits belonged to the bankruptcy estate, leaving depositors as unsecured creditors.
- Rehypothecation risk: the platform can pledge your deposit for its own activity, so your BTC may sit behind obligations you can’t see.
- Smart contract risk: a bug or exploit in a DeFi protocol can drain deposited funds.
- Wrapped BTC risk: a wrapped token is only as sound as the custodian or bridge holding the BTC behind it.
- Lock-up and rate risk: advertised rates change with borrowing demand, and some products lock your BTC for a fixed period.
