You can sign a message w/ a key and then take the resulting signature and recover the address from the message and signature.

Check out this gist

ts-node sign-message-and-recover-address.ts
Address: X-local18jma8ppw3nhx5r4ap8clazz0dps7rv5u00z96u
Message: From snowflake to Avalanche
Signature: Df5bvmWnqRYSpWBbJX3KNPnKNgWhoefSjQ6ZbB7hNiH8xzmJcssaeEFwotwfwC8FvriJUfueHfULXdouFq9sAbFwmJ1S5U

Recovering address from message and signature...

You should be able to do something similar where the serialized transaction is the message.

This doesn't solve my problem. I don't have the message nor the signature, so I can't recover the public key (so the address)

Message that signed is the transaction which input refers to. If I send another query just to get the previous tx (message that signed) I can also get address from outputs. No point for address recovery.

I am looking for a way to use Avalanchejs for this.
As I understand Avalanche transactions doesn't have public key info in inputs, so no possibility to get address from inputs (w/o sending another query to the node)

GetTxByID isn't a method on AvalancheJS. Can you provide any more details? I'm guessing you mean getTx.

@farukterzioglu can you provide a gist of what you're doing?

while you have the UnsignedTx object,

you can serialize it to find a breakdown of the transaction

let serialized: any = unsignedTx.serialize("display")
console.log(JSON.stringify(serialized))

you would get something that looks like the following.
