require(condition, "0xc86044d2"); Or more commonly, using custom errors (Solidity 0.8.4+):
Treat 0xc86044d2 as a clue, not an answer. To decode it, examine its environment—the surrounding bytes, the software version, and the transaction logs. If you can share where exactly you found this identifier (e.g., “in the calldata of a transaction to Uniswap V2”), a much more precise answer becomes possible. Do you have additional context for 0xc86044d2 ? If you saw it in a specific transaction hash, error log, or piece of code, providing that information will help narrow down the interpretation to a single, actionable answer.
