This repository contains the Cairo and Solidity code for the L1<>L2 bridges of StarkNet, as well as StarkNet's ERC20 token contract implementation that interacts with the bridges. You can read the documentation of the bridges here and the documentation of the general L1<>StarkNet messaging system here.
You can find the L1 addresses and L2 addresses for the deployed bridges on StarkNet Alpha on Goerli and on Mainnet here.
Note: The frontend of the bridges, can be found here.
If you are not familiar with Cairo, you can find more details about it here.
