Efficiently get addressFrom from the transaction list

[sandrich]

Hi

I was wondering what an efficient way is to get the fromAddress from the transaction list?

ie. from endpoint https://ocean.defichain.com/v0/testnet/address/tf1q74jn0ddazjlw6nmra4a40fcquqhrqhlf92egd8/transactions

As of now I have to go through each transaction and load the vin? Then from there translate the address from script hex? Seems very inefficient if I have to do that for lots of transactions.

I see here that hid is a hashed verison that contains addressFrom. But not sure this can be extracted.

Any help is appreciated

Hey, I'm assuming the data type is encoded as Script Hex?

You can use this package to parse and decode/encode them https://github.com/JellyfishSDK/jellyfish/tree/main/packages/jellyfish-address

Thanks this I know. The problem is that v0/testnet/address/xxx/transactions does not include the sender address which means I have to do a second request to v0/testnet/transaction/xxx/vins and I was wondering if I can prevent that and capture a utxo transaction including its sender address in one API call?

I am exploring the API and not very familiar with it. But I think your idea is good as it compile more useful data in 1 request. However, I can't figure out how you get address from v0/testnet/transaction/xxx/vins. I try also v0/testnet/transactions/tttt/vouts but not geting address either. Any suggestion ?
