Research direction

Start by reproducing the Rinkeby v3 add-liquidity flow with token address 0x1faa0c671b6336527efd167f7d1c6fc1b8a05d1a. Inspect the supplied estimateGas transaction and its M0 revert to determine why the liquidity call fails. Done means the affected token can add liquidity successfully without the gas-estimation error.
