I have generated a ScriptTransaction from typescript sdk and want to generate signature separately without using the wallet client (basically generate ECDSA signature from txn data hash separately) and then send signature and txn to the network. Is there a method that supports sending raw txn hash/…

This is resolved now. It was typo on my end. Thanks.

Hey @singhparshant , did you see the docs around signing transactions ? You can also find the source code example (unit test) here . Please let me know if that helps.

@anderson Thanks for the reply. Yes, I checked this, but i don’t see the option to add a from address, i think it uses the wallet address as the sender. I want to assemble a custom transaction.

Hello @singhparshant , how are you? I am unsure If I understand what you are trying to achieve. But I assume that is to get the hash of a ScriptTransaction and use it to generate an ECDSA signature, then add this signature to the ScriptTransaction before submitting it. If so this can be achieved b…

[image] Torres-ssf: const compactSignature = splitSignature(hexToBytes(signature)).compact; thank you. I think this is what i require. Will give it a try. Quick question : const compactSignature = splitSignature(hexToBytes(signature)).compact; Is this functionality present in fuel-ts some…

@singhparshant [image] singhparshant: Quick question : const compactSignature = splitSignature(hexToBytes(signature)).compact; Is this functionality present in fuel-ts somewhere ? No, we don’t have this functionality explicit defined on the fuels-ts. But you can use the following NPM pac…

@Torres-ssf Looks like the hexToBytes method is deprecated: export const hexToBytes = (hex: string): Uint8Array => { ...... return _unprefixedHexToBytes(hex) } The signature '(hex: string): Uint8Array' of '_unprefixedHexToBytes' is deprecated.ts(6387)

Also, in this unit test , request.updateWitnessByOwner is being used, as opposed to the one that you suggested scriptTransactionRequest.witnesses.push(compactSignature) Are they both same, do these results in similar transaction request ?

Hello @singhparshant You can use arrayify (which can be imported from fuels) instead of hexToBytes. import { arrayify } from 'fuels' The request.updateWitnessByOwner replaces a placeholder zeroed witness entry that was added on behalf of one account. It will extract the witness index from the res…

@Torres-ssf I am assembling the txn and trying to send to the network, however i am getting NoSpendableInput error. I am not adding anything in the inputs array of the txn request, just pushing the signature. What should i push to the input array to make it work ? I don’t want to use wallet and the…

I am still working on it. I have some issues with React-Native currently.
