Combine Tx data + Signature ( Generated using @cosmjs/ledger-amino)

[arunsybex]

Frontend Signing component

import { LedgerConnector, LedgerSigner } from "@cosmjs/ledger-amino";
let transport = await TransportWebUSB.create();    
    const signer = new LedgerSigner(transport, {
      testModeAllowed: true,
      hdPaths: [stringToPath(this.path)],
      prefix: this.prefix
    });

    const [firstAccount] = await signer.getAccounts(); 
    let sig_doc : StdSignDoc = {"chain_id":"osmo-test-4","account_number":"253513","sequence":"0","fee":{"amount":[{"amount":"100","denom":"uosmo"}],"gas":"250"},"memo":"Some memo","msgs":[{"type":"cosmos-sdk/MsgSend","value":{"amount":[{"amount":"1000","denom":"uosmo"}],"from_address":"osmo1sr4jyvtk4kfwljywdnuzjurqlzlunsmvzadjq3","to_address":"osmo1z38jgyhkxx2wxzapm9c7hfryx0hh650h05m33h"}}]}

    let { signature, signed }  = await signer.signAmino(firstAccount.address, sig_doc)
    console.log(signature, signed);

Above signAmino giving Amino response but all LCD URLs not accepting Amino StdTx.

How to broadcast this?

[webmaster128]

CosmJS does not support the LCD API anymore. You need to connect via Tendermint RPC for broadcasting.

@webmaster128 how to generate encoded transaction bytes from sign amino response? please share some source code.
