Interlay Lending review

Interlay is a Bitcoin DeFi project that aims to let BTC holders use their coins in decentralized finance without giving up custody to a centralized exchange. Its core product is iBTC, a token issued against BTC locked in vaults. The project's website describes lending, borrowing, swapping and leveraged positions as the main uses.

The project's homepage claims about 53 million dollars in DeFi volume and 17 supported networks. Those figures are the project's own and are not checked against an independent source here. Its governance token is INTR, and the site says the protocol is governed by token holders. Third-party sources describe Interlay as a network that connects Bitcoin to platforms such as Polkadot and Ethereum, and one review site reports that the project raised a seed round in 2021.

The product is aimed at Bitcoin holders who want yield or borrowing power without selling their BTC. It is a more complex setup than a simple wallet or exchange, because it involves vault operators, collateral and cross-chain steps. The project's materials are clearest on how the mechanism works and less specific on lending terms and risk.

Bitcoin itself does not run smart contracts, so it cannot natively be used in DeFi apps. Interlay sits between Bitcoin and other blockchains so that BTC can be used there. The project describes it as a modular, programmable layer that connects Bitcoin to a multi-chain ecosystem.

The basic route starts with a vault. A user locks native BTC with a vault operator, and the system issues iBTC at a 1:1 ratio to the locked amount. The site says vault collateral, including assets such as USDT and DOT, is held as extra protection for the BTC. Vault operators are a distinct role: anyone can run one and earn fees on BTC volume, according to the project.

Once a user holds iBTC, it can be used in connected DeFi apps. The site describes using it as collateral to borrow assets or open leveraged positions, trading it against other assets, and earning on it. To exit, the user redeems iBTC for native BTC on Bitcoin.

Interlay does not publish a fee schedule for users. The project's site says that anyone can operate a vault and earn fees on BTC volume, which points to vault operators as the parties who earn those fees.

Borrowing rates, swap costs, redemption charges and liquidation penalties are not stated in the material reviewed. Check the Launch App and the documentation before you commit funds, and compare the all-in cost of moving BTC into iBTC and back out.

The project's site says Interlay has been audited by industry leaders in blockchain security and links to an audit page. The named auditors, report dates and findings are not shown in the material reviewed, and the data available lists no audits for this product. Treat the audit claim as unverified until you can read the reports yourself.

Custody is split in a way that matters. Users keep their BTC locked with a vault operator in return for iBTC, so the vault operator and the smart contracts are counterparties. The site says vault collateral and insurance protect users, and it says the network is decentralized. Neither the insurance terms nor the collateral ratios are published in the material reviewed.

The project does not publish regulatory status for the lending or swap products. Smart contract risk, bridge risk and liquidation risk all apply. DeFi lending involves risk of loss, and it is not a savings product. Anyone using these tools should be 18 or older where that is the legal age, and should check that DeFi lending is legal where they live.

Interlay is for experienced crypto holders who already hold Bitcoin and want to use it as collateral or in simple DeFi trades. It is less suited to people who want a fixed-return product or a simple, fully insured deposit. Readers new to DeFi should first learn how collateral and liquidation work.
