NEAR Releases Ethereum Rainbow Bridge Upgrade and Governance Plan

For any smart contract (especially contracts that hold/manage large amounts of tokens), the upgradeability process and its governance are important aspects. This process defines who can and how to change the behavior of smart contracts by uploading a new version of contract execution code. Obviously, the upgradeability process itself can also be continuously adjusted and "upgraded". This article aims to introduce smart contract upgradeability patterns, match them with Rainbow Bridge architecture, and propose a phased plan for governance and other improvements to these upgrades.
