Base Transfer Simulation and Revert Decoder
https://base-onchain-tools.dolerite.workers.dev/v1/base/simulate-transferOverview
Will this token payment actually go through, and if not exactly why. Simulates the transfer without spending gas, decodes the real revert reason (Error(string), Solidity Panic codes translated to English, or an unknown custom error selector), and separately reports balance and allowance blockers. Knows a caller with no ETH is fine for a gasless EIP-3009 transfer or a sponsored relayer. Query params: from, to, amount, optional token and spender.
