Private Key Auth

Authorize transactions with a private key.

The private key auth type allows FunWallet transactions to be authorized by an ECDSA private key. This option can be useful for testing & debugging.

Create a FunWallet with a private key owner

The following example showcases how to create a FunWallet with an EOA private key as an owner & transaction authorizer.

,
SingleAuth.js
const { FunWallet, configureEnvironment } = require("fun-wallet")
const { Eoa } = require("fun-wallet/auth")
const { fundWallet } = require("fun-wallet/utils")


const PRIVATE_KEY = "0x98e9cfb323863bc4bfc094482703f3d4ac0cd407e3af2351c00dde1a6732756a"
const API_KEY = "MYny3w7xJh6PRlRgkJ9604sHouY2MTke6lCPpSHq"


const create = async () => {
    await configureEnvironment({
        apiKey: API_KEY
    })


    const auth = new Eoa({ privateKey: PRIVATE_KEY })
    const uniqueId = await auth.getUniqueId()
    const wallet = new FunWallet({ uniqueId })


    // NOTE: Wallet must be prefunded if not using a sponsor
    // await fundWallet(funder_auth, wallet, .005)


    // auth: an auth object (see Auth API)
    const receipt = await wallet.create(auth)
}


create()

Transfer assets from a FunWallet with a private key owner

The following example showcases how to initialize a FunWallet with an EOA private key as an owner & transfer tokens to an external address, authorizing this transaction with the private key.

,
transfer.js
const { FunWallet } = require("fun-wallet")
const { Eoa } = require("fun-wallet/auth")
const { fundWallet } = require("fun-wallet/utils")


const PRIVATE_KEY = "0x98e9cfb323863bc4bfc094482703f3d4ac0cd407e3af2351c00dde1a6732756a"


const auth = async () => {
    // Authenticate with Eoa class
    const auth = new Eoa({ privateKey: PRIVATE_KEY })
    const uniqueId = await auth.getUniqueId()


    // Perform actions with the FunWallet
    const wallet = new FunWallet({ uniqueId })


    // NOTE: Wallet must be prefunded if not using a sponsor
    // await fundWallet(funder_auth, wallet, .005)


    await wallet.transfer({ to: '0x175C5611402815Eba550Dad16abd2ac366a63329', amount: .001, token: "eth" })
}
