BiFi launches Bitcoin lending on Ethereum

BiFi, the multichain decentralized finance lending protocol powered by Bifrost’s multichain technology, launched native Bitcoin (BTC) lending on the Ethereum network for the first time in DeFi history. 

BiFi directly connects Bitcoin and Ethereum networks on its platform so users do not have to convert Bitcoin to Wrapped Bitcoin (wBTC) or any other Bitcoin-pegged assets to use on DeFi. A third-party chain does not intervene in using Bitcoin. BiFi’s native Bitcoin lending and borrowing services allow users to avoid additional transaction fees as they do not have to convert Bitcoin into Wrapped Bitcoin and users can also avoid slippage problems during the converting process. 

BiFi users can borrow native Bitcoin by depositing ERC-20 assets or borrow ERC-20 assets by depositing Bitcoin on the Ethereum network. The processes for depositing and borrowing are the same as lending other assets on BiFi lending. 

One difference, however, in using Bitcoin lending is that users will need to register three addresses before they start lending or borrowing Bitcoin on BiFi. Two addresses (Bitcoin deposit address and Bitcoin repayment address) are issued automatically to the user when they click on “Deposit Bitcoin.” Users will need to input the third address (their own Bitcoin address) for depositing Bitcoin to the BiFi protocol. 


The transfer of data is important to Bitcoin-Ethereum connectivity. Transactions must be transferred from one chain to another precisely and without any error. This computational integrity of blockchain transactions ensures transparency and security.

BiFi utilizes this computational integrity of trustworthy blockchains rather than creating its own new chain. Bifrost uses cryptographic proofs to verify the accuracy of transactions on the Bitcoin network and on-chain on Ethereum smart contracts. BiFi uses Bifrost to verify that transactions are correct using the fraud proofs method. This is a method used in Optimistic Rollups of Ethereum chains on layer two. 

Moreover, BiFi highly emphasizes the importance of protocol security. The BiFi team develops its own protocol codes and conducts several smart contract audits when it launches its new services and features. 

About Bifrost

Bifrost is a multichain middleware platform that enables developers to create decentralized applications on top of multiple protocols. Not restricted to a single blockchain, Bifrost creates a new environment where developers can combine the best protocols to develop substantially more scalable and flexible DApps.

About BiFi

BiFi opens a new era of DeFi, offering the first native BTC lending by directly connecting the Bitcoin and Ethereum network. Powered by Bifrost’s multichain technology, BiFi will connect not only Bitcoin, Ethereum and the Binance Smart Chain, but also other blockchains such as Polkadot, Klaytn, Cardano and more. Through this multichain connectivity, BiFi will lower gas fees, increase accessibility and expand the ecosystem to enable the creation of more innovative financial products for more people.
