Get a read-only cosmwasm client
import { CosmWasmClient } from "cosmwasm";
// This is your rpc endpoint
const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";
async function main() {
const client = await CosmWasmClient.connect(rpcEndpoint);
console.log(client);
}
main();
Create a wallet and a signing stargate client
import { SigningCosmWasmClient, Secp256k1HdWallet } from "cosmwasm";
// This is your rpc endpoint
const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";
// Using a random generated mnemonic
const mnemonic = "rifle same bitter control garage duck grab spare mountain doctor rubber cook";
async function main() {
// Create a wallet
const wallet = await Secp256k1HdWallet.fromMnemonic(mnemonic);
// Using
const client = await SigningCosmWasmClient.connectWithSigner(
rpcEndpoint,
wallet
);
console.log(client);
}
main();
Interacting with contracts
import { CosmWasmClient } from "cosmwasm";
// This is your rpc endpoint
const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";
// This is your contract address
const contractAddr = "wasm19qws2lfd8pskyn0cfgpl5yjjyq3msy5402qr8nkzff9kdnkaepyqycedfh";
async function main() {
const client = await CosmWasmClient.connect(rpcEndpoint);
const config = await client.queryContractSmart(contractAddr, { config: {} });
