How it works

Toucan Crosschain Messenger will allow users to bridge carbon pool tokens between EVM chains. Until now for EVM-based cross-chain bridging and communication, the Abacus message-bridge system is being utilized.
Abacus is a generalized interchain messaging protocol that allows developers to send arbitrary data from one blockchain to another. Abacus provides an on-chain API to send and receive interchain messages. This API is secured by a delegated proof-of-stake protocol combined with an application-specific approach to security called sovereign consensus.
