Token list: bridged asset standard

[willhennessy]

Hi Set team!

We recently proposed a standard extension to the Token List schema to capture the relationship between L1 and L2 bridged tokens. For example, the entry for L1 DAI would contain a mapping to the DAI address on optimism, arbitrum, etc.

Schema: https://github.com/Uniswap/token-lists/issues/51#issuecomment-952268629

If you want to drive swap volume on layer 2 networks, this is a great way to do it! Right now the Uniswap App shows 0 tokens from the Set token list on optimism and arbitrum.

Here are some reference examples

• ethereum-optimism/ethereum-optimism.github.io#35

Thanks, Will
