⋅ The Canonical Message Bridge

The main “bridge”, on a technical level, in Linea is the Canonical Token Bridge. These smart contracts manage token transfers between layers by accepting requests and sending messages to initiate the transfer process.

⋅ The Postfrens

Programs, acting as “postmen,” deliver the message to the other network. The receiving smart contract executes actions based on the received message.

⋅ The Canonical Token Bridge

If you want to move tokens between L1 and L2, we recommend you use the bridge made on top of the Canonical Message Bridge.
