when passed to sendrawtransaction(), generates the following error:
error code: -26
error message:
non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation) (code 64)
The bitcoin source seems to suggest the transaction's rejected for being non-standard: my transaction was based on the developer example at https://bitcoin.org/en/developer-examples#p2sh-multisig which I thought would be standard, and the error occurs on testnet where I thought the related isStandard() checks are turned off.
I am looking for insight into where I've managed to go wrong!
Detail: code, output, conf files, versions, transaction decode, redeem script decode
I have rewritten the developer example as a self-contained bash script that resets regtest back to a known state then works through the snippets, or attempts to run on testnet. Where necessary, the calls have been adjusted to reflect API changes such as signtransactionwithkey vs signtransaction:
