Bridge

Question

Can you send USDT from Solana to ETH? How about Polygon/Base to ETH?

Bridge

An EVM bridge refers to a system or protocol designed to connect two or more blockchains that are compatible with the Ethereum Virtual Machine (EVM). The purpose of these bridges is to enable the transfer of assets and data between different EVM-compatible chains (like Ethereum, Binance Smart Chain, Polygon, Avalanche, etc.) while maintaining security, decentralization, and trust minimization.

How an EVM Bridge Works:

1. Lock and Mint (Token Bridge):
   • Locking: When a user wants to move assets (e.g., tokens) from one blockchain to another (say, from Ethereum to Binance Smart Chain), the assets are “locked” in a smart contract on the source blockchain (Ethereum). The original tokens are not moved; they are simply secured in the contract until they are redeemed or unlocked.
   • Minting: Once the assets are locked, the bridge’s smart contract on the destination blockchain (BSC, for example) will mint an equivalent number of tokens. These minted tokens represent the value that the user can now use on the destination blockchain.
2. Burn and Release:
   • When the user wants to move assets back to the source blockchain (say, from BSC to Ethereum), they initiate a process where the tokens on the destination blockchain are “burned” (destroyed).
   • After the tokens are burned, the bridge’s smart contract on the source blockchain (Ethereum) will release the equivalent amount of tokens back to the user.
