The addresses of all Toucan contracts deployed across all mainnet and testnet networks can be found here.
Error codes
We use custom error codes (not to be confused with Solidity custom errors) in our pool contracts to keep the size of the contracts as small as possible.
Below you can find the existing error codes and a description for each one.
