Additional Context

timolegros commented 2 weeks ago

If supply (floating supply) in the launchpad Trade event is equal to the total supply then trigger transferring liquidity to Uniswap.

Total supply will be available in the Tokens model after: https://github.com/hicommonwealth/commonwealth/issues/9394#issuecomment-2429672355

Also, after transferring liquidity "lock" the token. The handler should be idempotent such that retries will "lock" a token even if the liquidity transfer was completed in a previous try.
