signing material
What to sign, per chain family; sign says which shape it is. evm-tx: sign and send each of txs in order, from from when given. btc-payment (fund): pay amountSats to payTo (and feeAmountSats to feePayTo when present). btc-sighash (claim/refund): sign each of sighashHexes, then broadcast { psbtBase64, signaturesHex, preimageHex? }. solana-tx: sign transactionBase64 and broadcast it. tron-txid: sign each transactions[].txID and broadcast each signed transaction.
