What it means
A transaction that reverts with the raw data 0x3f4ab80e hit the custom error TRANSFER_FAILED, defined in Common DeFi convention. The explorer shows the hex because it does not have the contract's ABI to translate it.
A custom-error form of the classic transfer failure: a token the contract tried to move refused the transfer.
How to fix it
Check the token for restrictions, fees on transfer, or a paused state, and verify approvals and balances.
