Returns an interface used to sign transactions on the Sei chain. This package contains helper functions to get a SigningCosmWasmClient with Sei registry and amino types from @sei-js/proto used for smart contract execute messages.

Example: Getting a client

import { getSigningCosmWasmClient } from "@sei-js/cosmjs";


// Create a CosmWasmClient
const signingCosmWasmClient = await getSigningCosmWasmClient(RPC_URL, offlineSigner);

Example: Execute Example: Mint an NFT

import { getSigningCosmWasmClient } from "@sei-js/cosmjs";
import { calculateFee } from "@cosmjs/stargate";

// Create a CosmWasmClient
const signingCosmWasmClient = await getSigningCosmWasmClient(RPC_URL, offlineSigner);

// Execute a message on a smart contract
const fee = calculateFee(150000, "0.1usei");
const msg = { mint: {} };

const result = await signingCosmWasmClient.execute(SENDER_ADDRESS, CONTRACT_ADDRESS, msg, fee);
