Token Bridge 1.2.0 Release


The TokenBridge repository contains the code base for the following components:

  • Oracle
  • Monitor
  • UI

The recommended version of the TokenBridge contracts to be used with this release is 3.3.0.

The goal of the release is to support two tokens Sai/SCD and Dai/MCD as it was planned in the Phase 2 of the xDai brige migration.

The steps that are required to upgrade the TokenBridge Oracle from the previous 1.1.x release were implemented in form of a upgrade script. The script needs to be modified to work with correct 1.2.0 version of the docker image:
