BRC-20 Bridge

Comsats develops a bridge between BRC-20 (Bitcoin) and EVM (Ethereum, Binance Chain, Polygon,...) to help users easily access the advantages of different chains.

How does it work?

Bridge Bitcoin to EVM

Describe the bridge mechanism from Bitcoin to Ethereum

• Step 1: Connect to the Bitcoin wallet and transfer BRC-20 to Pool Bridge (transactions need 1-2 block confirmations)

• Step 2: Provide EVM wallet address to receive tokens by offline signing on Bitcoin wallet

• Step 3: Connect to the provided EVM wallet address and Withdraw

Currently Comsats also provides a bridge from Bitcoin to Ethereum, BNB Chain with zero service fees.

Bridge EVM to Bitcoin

Describe the bridge mechanism from Ethereum to Bitcoin

• Step 1: Connect to the EVM wallet, approve and transfer token to Pool Bridge (Bitcoin wallet address to receive BRC-20 will also be required and recorded directly into Metadata in the transaction)

• Step 2: The Comsats system confirms and begins performing Inscribe Transfer and Transfers BRC-20 from Pool Bridge to the BRC-20 address that the user has provided

The bridge process from Ethereum, BNB Chain to Bitcoin takes 30 minutes to several hours to execute (depending on the transaction confirmation speed of the Bitcoin network).

The fee is fixed at 0.01-0.02 ETH, 0.1-0.2 BNB (this fee is used as the BRC-20 inscribe fee).
