Create a wallet

Introduction

Creating a wallet establishes its first authority and the permissions that authority can use.

Use when: your application needs an active wallet that can receive assets and execute transactions.
For: app developers onboarding a user or provisioning an application wallet.

How it works

Choose the owner and a funded Solana fee payer.
Generate a wallet ID and build the creation instruction.
Submit the transaction and wait for confirmation.
Fetch the wallet to obtain its asset address and current roles.

Addresses

Address	Use
`configAddress`	Read roles with `fetchSwig` and prepare operations
`walletAddress`	Receive SOL and own token accounts

SDK example

This example uses one Ed25519 keypair as owner and payer. The owner receives All permission; the payer funds account creation and fees. Supply your RPC Connection and application-owned signer after installing the SDK.

import {
  type Connection,
  type Keypair,
  Transaction,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  Actions,
  createEd25519AuthorityInfo,
  fetchSwig,
  findSwigPda,
  getCreateSwigInstruction,
  getSwigWalletAddress,
} from "@swig-wallet/classic";

async function createWallet(connection: Connection, owner: Keypair) {
  const id = crypto.getRandomValues(new Uint8Array(32));
  const configAddress = findSwigPda(id);
  const instruction = await getCreateSwigInstruction({
    payer: owner.publicKey,
    id,
    authorityInfo: createEd25519AuthorityInfo(owner.publicKey),
    actions: Actions.set().all().get(),
  });
  const signature = await sendAndConfirmTransaction(
    connection,
    new Transaction().add(instruction),
    [owner],
    { commitment: "confirmed" },
  );
  const swig = await fetchSwig(connection, configAddress, {
    commitment: "confirmed",
  });
  const walletAddress = await getSwigWalletAddress(swig);
  return { configAddress, walletAddress, signature };
}

Store both returned addresses; use the wallet address for deposits.
Use another authority constructor for passkey, Ethereum, or program approval.
For a browser signer, use its wallet adapter as described in Sending transactions.
Give application signers narrower access with Add a role.
