As decentralized finance (DeFi) expands across multiple blockchain ecosystems, the need for seamless interoperability is greater than ever. Swapping assets across chains has traditionally required centralized exchanges or wrapped tokens — both of which introduce friction and risk.
RenBridge offers a solution: a secure, decentralized protocol that allows users to bridge assets like BTC, ZEC, and BCH across blockchains without intermediaries. In this guide, you'll learn what RenBridge is, how it works, and how to use it efficiently.
RenBridge is a cross-chain bridge protocol that allows users to move crypto assets between different blockchains in a trustless manner. It’s powered by RenVM, a decentralized virtual machine network that facilitates secure and private interoperability.
Unlike centralized bridges or wrapped token services, RenBridge doesn’t rely on third parties. Users maintain full control of their assets throughout the bridging process.
Decentralized Interoperability
Transfers occur via RenVM — a trustless, decentralized custodian with no single point of failure.
Multi-Chain Support
Supports major chains like Bitcoin, Ethereum, Binance Smart Chain, Polygon, Arbitrum, Avalanche, and more.
No Wrapped Token Complexity
Native assets are bridged without manual wrapping or unwrapping by the user.
Secure by Design
Powered by a decentralized network of nodes that validate transactions.
Transparent & Open Source
Code is public and verifiable via RenBridge GitHub.
RenBridge uses RenVM, which locks the original asset on its native chain and mints a 1:1 representation on the destination chain. For example:
You send BTC to a RenVM-generated Bitcoin address.
RenVM locks your BTC and mints an equivalent amount of renBTC on Ethereum.
You can now use renBTC across Ethereum-based DeFi platforms.
When you're done, you send renBTC back to RenVM to release your original BTC.
This process happens entirely on-chain and is cryptographically secured.
Welcome to RenBridge and make sure you're using the legitimate domain.
RenBridge supports multiple Web3 wallets like MetaMask, Ledger (via Web3 connectors), and WalletConnect. Choose your wallet and network.
Select the origin chain (e.g., Bitcoin)
Select the destination chain (e.g., Ethereum)
Enter the amount you wish to bridge.
RenBridge will provide a deposit address on the origin chain. Send your asset there.
Once RenVM receives and confirms your asset, it mints the corresponding token (e.g., renBTC) on the destination chain.
Use your bridged asset in DeFi protocols, or bridge it back to the original chain when you're done.
Bring BTC to Ethereum for use in lending protocols like Aave or Compound.
Bridge assets to Layer 2 networks for faster and cheaper transactions.
Access liquidity pools on non-native chains.
Hedge or diversify portfolios across ecosystems.
What chains does RenBridge support?
Bitcoin, Ethereum, Polygon, BNB Chain, Avalanche, Fantom, Arbitrum, Solana, and more.
Is RenBridge safe?
Yes. RenBridge is powered by RenVM, a decentralized network of nodes that uses secure multiparty computation (sMPC) to manage assets without custodians.
What are the fees?
Users pay blockchain gas fees and a small fee to RenVM (~0.1%). Fees vary depending on the network.
Can I reverse a failed transaction?
Transactions cannot be reversed once processed, but failed or stuck transactions can usually be recovered via the recovery tool provided on the website.
