TokenBridge Contracts 3.1.0 Release


This version of TokenBridge supports operations in four modes:

  • native coin to an bridgeable ERC20 token;
  • an ERC20 token to a bridgeable ERC20 token;
  • an ERC20 token to a native coin;
  • relaying arbitrary messages (Arbitrary Message Bridging, AMB).

This release contains a reference implementation of the functionality to relay ERC677-to-ERC677 tokens through the Arbitrary Message Bridge. The documentation describing the contracts interactions for this implementation described in the the manual “How to develop a cross-blockchain application by using AMB bridge”

  • Add erc677 to erc677 bridge on top of AMB #273
  • Add result information for AMB message call #282
  • Add methods to fix failed messages in erc677 to erc677 on top of AMB #284


  • Update project dependencies to latest versions #283
