eth_getTransactionByHash on Ethereum
Fetches a transaction's full details (from, to, value, input, gas) by its hash. Returns null if the transaction is unknown or still pending propagation.
Null covers both 'unknown' and 'still propagating', so treat it as 'not yet' and retry rather than 'never'. The blockNumber field stays null until the tx is mined — the cleanest pending-vs-mined check.

Transactions on Ethereum
Mainnet's mempool is competitive: underpriced transactions linger. Price transactions from eth_feeHistory percentiles, and replace a stuck transaction by re-sending the same nonce with a higher priority fee.
