Combine multi address's UTXO into a transaction input?

See original GitHub issue

I want to Combine multi address’s UTXO into a transaction input. It is used in case I want to centralize all of my assets into one address in one transaction.

I saw a transaction with multi addresses as UTXO but no docs explain about that. Is there anyone know how can it possible with NEO?

Please help me. Thanks.

AFAIK you can’t do this with neon-js in a single transaction, because the sendAsset api only allows for one account to be specified in the config object. You would have to loop through all the accounts you want to consolidate and issue a separate transaction for each to a single destination address.

The transaction above probably came from a full-node wallet like neo-gui or neo-cli. Those wallets will combine all available inputs needed to construct the UTXO when the output amount exceeds the balance of a single address.

Thank you @hal0x2328. So read the neo code and figure out that they try to sign a transaction multi-time and add all of the witnesses into transaction witnesses. I’m trying to implement it in an offline machine.
