Contract Migration

Learn how to do contract migration with SecretJS.

Secret Network Client Setup

import { SecretNetworkClient, Wallet } from "secretjs";

const wallet = new Wallet("Your mnemonic words go here");

const secretjs = new SecretNetworkClient({
  chainId: "pulsar-3",
  url: "https://pulsar.lcd.secretnodes.com",
  wallet: wallet,
  walletAddress: wallet.address,
});

SecretJS Contract Migration

secretjs.tx.compute.migrateContract()

Migrate a contract's code while keeping the same address. Invokes the migrate() function on the new code.

Input: MsgMigrateContractParams

const tx = await secretjs.tx.compute.migrateContract(
  {
    sender: myAddress,
    contract_address: contractAddress,
    code_id: newCodeId,
    code_hash: codeHash, // optional but way faster
    msg: {
      migrate_state_to_new_format: {},
    },
    sent_funds: [], // optional
  },
  {
    gasLimit: 100_000,
  },
);
