Working cosmos example!

You'll need to install Squid via npm first, then put in your cosmos wallet mnemonic and you're good!

SDK <=v1.12.0

import { RouteResponse, Squid } from "@0xsquid/sdk";
import { SigningStargateClient, DeliverTxResponse } from "@cosmjs/stargate";
import {
  DirectSecp256k1HdWallet,

(async () => {
  const baseUrl = "https://testnet.api.0xsquid.com";

  // instantiate the SDK
  const squid = new Squid({
    baseUrl: baseUrl,
  });

  // init the SDK
  await squid.init();
  console.log("Squid inited");

  const mnemonic = "<your_mnemonic>";
  const osmosisRpc = "https://rpc.osmotest5.osmosis.zone"; // osmosis testnet rpc endpoint

  const getSignerFromMnemonic = async (): Promise<OfflineDirectSigner> => {
    return DirectSecp256k1HdWallet.fromMnemonic(mnemonic, {
      prefix: "osmo",
    });
  };
  const offlineSigner: OfflineDirectSigner = await getSignerFromMnemonic();

  const signerAddress = (await offlineSigner.getAccounts())[0].address;
