ZKsyncAdvancedzksolc compiles to EraVM, not the EVM: CREATE/CREATE2 addresses differ, factories need known bytecode, every account is a smart account, pubdata changes gas, and the 2300-gas .transfer stipend can fail.

EthereumBeginnerEtherscan recompiles your source and compares bytecode. Verify with forge --verify or hardhat verify and a V2 API key; mismatches come from compiler version, optimizer, viaIR, EVM version, constructor args or paths.

EthereumBeginnerIt's usually a max fee below the base fee, a low tip, or an earlier stuck nonce. Speed up by resending with the same nonce and higher fees; cancel by sending 0 ETH to yourself with that nonce.

HyperledgerIntermediateThe endorsements attached to the transaction don't satisfy the chaincode policy at validation. Check the real policy (often MAJORITY by default), endorse from every required org, and verify roles.

BitcoinIntermediateA stuck transaction pays too low a feerate. The sender can replace it with a higher-fee version (RBF), or anyone with an output can spend it in a high-fee child so the package gets mined (CPFP).

SolanaBeginnerSome account would end the transaction with more than zero lamports but less than its rent-exempt minimum. Find it by index, then fund it fully, sweep it to zero, or fund your reallocs.

EthereumIntermediateThe EVM hit a REVERT and undid the call. The reason is in the revert data: decode Error(string), Panic codes and custom errors with ethers, or replay a failed transaction with cast run.
#smart-contracts#solidity#troubleshooting
SolanaIntermediateFetch the blockhash at confirmed commitment right before signing, add a priority fee, and rebroadcast the same signed bytes until confirmed or past lastValidBlockHeight; only then re-sign.
#transactions#troubleshooting
EthereumIntermediateNonce too low means that nonce is already used; underpriced means a pending tx holds it and you didn't raise both fee fields enough. Pick nonces from "pending" and serialize sends per key.
