@cosmology/cosmjs

Cosmjs

Wrapper of @uni-sign/auth and @uni-sign/cosmos to fit corresponding interfaces in @cosmjs

Usage

npm install @cosmology/cosmjs

To sign messages (taking stargate signing client as example)

// import * from "@cosmology/cosmjs"; // Error: use sub-imports, to ensure small app size
import { StargateSigningClient } from "@cosmology/cosmjs/stargate";

const client = StargateSigningClient.connectWithSigner(<rpc-endpoint>, <offline signer>);
const result = await client.signAndBroadcast(<ADDRESS>, <MESSAGE>[], "auto");
// or you can use helper functions to do `signAndBroadcast`. taking send tokens as example
const result = await client.helpers.send(<ADDRESS>, <MsgSend message>, "auto", "");

console.log(result.transactionHash); // the hash of TxRaw

To construct an offline signer (taking direct signer as example)

import { Secp256k1Wallet } from "@cosmology/cosmjs/wallets/secp256k1";

const wallet = Secp256k1Wallet.fromMnemonic("<MNEMONIC_WORDS>", { prefix: "<prefix>" });
const directOfflineSigner = wallet.toOfflineDirectSigner();
