How do I create AX (ArgentX) contract using starknetjs?

Create AX (Argent X) account :

Here, we will create a wallet with the ArgentX smart-contract v0.2.3. This case is more complicated because we will have the wallet behind a proxy contract (in this way, the wallet contract can be updated). The contract classes of both contracts are already implemented in both Testnet 1 & 2.

If necessary OZ contracts can also be created with a proxy.

import { Account, ec, json, stark, Provider, hash } from "starknet";

compute address :

// connect provider
const provider = new Provider({ sequencer: { network: "goerli-alpha" } });

//new Argent X account v0.2.3 :
const argentXproxyClassHash = "0x25ec026985a3bf9d0cc1fe17326b245dfdc3ff89b8fde106542a3ea56c5a918";
const argentXaccountClassHash = "0x033434ad846cdd5f23eb73ff09fe6fddd568284a0fb7d1be20ee482f044dabe2";
    // Generate public and private key pair.
const privateKeyAX = stark.randomAddress();
console.log('AX_ACCOUNT_PRIVATE_KEY=', privateKeyAX);
const starkKeyPairAX = ec.getKeyPair(privateKeyAX);
const starkKeyPubAX = ec.getStarkKey(starkKeyPairAX);
console.log('AX_ACCOUNT_PUBLIC_KEY=', starkKeyPubAX);
// Calculate the future address of the ArgentX account
const AXproxyConstructorCallData = stark.compileCalldata({
    implementation: argentXaccountClassHash,
    selector: hash.getSelectorFromName("initialize"),
    calldata: stark.compileCalldata({ signer: starkKeyPubAX, guardian: "0" }),
});
const AXcontractAddress = hash.calculateContractAddressFromHash(
    starkKeyPubAX,
    argentXproxyClassHash,
    AXproxyConstructorCallData,
    0
);
console.log('Precalculated account address=', AXcontractAddress);

If you want a specific private key, replace stark.randomAddress() by your choice.Then you have to fund this address.

deployment of the new account :

If you have sent enough funds to this new address, you can go forward to the final step :

const accountAX = new Account(provider, AXcontractAddress, starkKeyPairAX);
const deployAccountPayload = {
    classHash: argentXproxyClassHash,
    constructorCalldata: AXproxyConstructorCallData,
    contractAddress: AXcontractAddress,
    addressSalt: starkKeyPubAX };
const { transaction_hash: AXdAth, contract_address: AXcontractFinalAdress } = await accountAX.deployAccount(deployAccountPayload);
console.log('✅ ArgentX wallet deployed at :',AXcontractFinalAdress);
