design-doc: convert-unified #46

Closed Joxess closed 4 months ago

Joxess commented 4 months ago

Description This document presents a solution for migrating OptimismMintableERC20, which corresponds to locked liquidity in L1, to the SuperchainERC20 standard to be interop compatible.

To do that, we suggest using the L2StandardBridge mint/burn rights over the legacy representations to allow easy conversion between the OptimismMintableERC20 and the corresponding SuperchainERC20.

In contrast to the isolated approach presented here https://github.com/ethereum-optimism/design-docs/pull/45, this PR focuses on the unified approach, where multiple legacy tokens can be converted into one single SuperchainERC20.

We have consensus on this approach, its good to begin work on specs and break the project into 2 workstreams, one for the work itself and one for backporting the registry to the chain
