Research direction

Start by reproducing the send flow on version 13.19.0 in Chrome on macOS, then trace the token standard and token-details lookup during transaction preparation. Done means the application identifies supported token standards such as ERC-20 or ERC-721, loads token details, and no longer reports the contract-standard error.
