0x2bc80f3a: T

error T()

What it means

A transaction that reverts with the raw data 0x2bc80f3a hit the custom error T, defined in Uniswap V3 core. The explorer shows the hex because it does not have the contract's ABI to translate it.

A deliberately tiny error name from V3's gas-golfed core, thrown for a timestamp-related check in observations. Reaching it as an end user is rare.

How to fix it

Retry from the dapp with a fresh quote. Persistent failures here are for the integrating dapp to debug.

Paste the hash and we decode the revert against the contract itself, including the values inside the error, free.
