Transfer Tokens

Send tokens to a wallet address or social media handle.

FunWallets can send ERC-20 tokens and base currencies (ETH, MATIC) to:

In both cases, the core logic is the same, with some small variance on how to calculate DEST_ADDR:

await wallet.transfer(auth, { to: DEST_ADDR, amount: AMOUNT, token: "USDC" })

Transfer tokens to a public address

The following flow demonstrates how to transfer 5 USDC on the Göerli testnet to DEST_ADDR.

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

// Replace these with your own
const PRIVATE_KEY = "0x98e9cfb323863bc4bfc094482703f3d4ac0cd407e3af2351c00dde1a6732756a"
const API_KEY = "MYny3w7xJh6PRlRgkJ9604sHouY2MTke6lCPpSHq"
const DEST_ADDR = "0x07Ac5A221e5b3263ad0E04aBa6076B795A91aef9"

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

    const auth = new Eoa({ privateKey: PRIVATE_KEY })

    // Get FunWallet associated with EOA
    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)
    // to: who you want to send the funds to
    // amount: amount to send
    // token: what you want to send
    const receipt = await wallet.transfer(auth, { to: TO_ADDR, amount: 5, token: "USDC" })
}

Transfer ETH to a Twitter handle

The following flow demonstrates how to transfer 0.00001 ETH on the Göerli testnet to @elonmusk on Twitter.

Once the ETH is transferred, @elonmusk can access these funds by creating a FunWallet with the right Twitter Auth Type & index = 0. This can be done by using Fun's demo app here).

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

// Replace these with your own
const PRIVATE_KEY = "0x98e9cfb323863bc4bfc094482703f3d4ac0cd407e3af2351c00dde1a6732756a"
const USER_TWITTER_HANDLE = "elonmusk"
const CHAIN_ID = "ethereum-goerli"
const API_KEY = "MYny3w7xJh6PRlRgkJ9604sHouY2MTke6lCPpSHq"

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

    const uniqueTwitterId = "twitter###" + USER_TWITTER_HANDLE
    const destAddr = await FunWallet.getAddress(uniqueTwitterId, index = 0, CHAIN_ID, 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)
    // to: who you want to send the funds to
    // amount: amount to send
    // token: what you want to send
    const receipt = await wallet.transfer(auth, {
        to: destAddr,
        amount: 0.00001,
        token: "eth"
    })
}

Important!

Ensure your privateKey starts with '0x'.
Ensure your account has enough funds to transfer and pay for gas. (ie: USDC, ETH)
If the token used is not available, use the token address.
