The Glider API is wallet agnostic. This means that as long as you can get an EIP-191 signature from the EOA that will own the portfolio, you can use the Glider API.

If you’ve followed along with the Quickstart guide you will notice there’s two cases where your wallet architecture will need to interface with Glider. The first is when you’re creating a portfolio, and the second is when you’re funding a portfolio.

​
Creating a Portfolio with Privy

During the Portfolio Creation process, an EIP-191 signature is required to authenticate ownership of the portfolio and provide Glider access to manage the assets within the portfolio.

1

Get the Message to Sign

Fetch the data to be signed by calling the https://api.glider.fi/v1/portfolio/create/signature endpoint.

// First, get the message to sign
const signDataResponse = await fetch(
  `https://api.glider.fi/strategies/sign-data/${strategy.strategyId}`,
  {
    method: "GET",
    headers: {
      "X-API-KEY": "your_api_key_here",
    },
  }
);

const signData = await signDataResponse.json();
const messageToSign = signData.message;
2

Sign the Message

Sign the message with the owner’s wallet. Privy provides a tutorial on signing a message through their SDKs.

This will likely require end user interaction to complete the signature.

privy.js
import { useSignMessage } from "@privy-io/react-auth";

const { signMessage } = useSignMessage();

// Optional UI options
const uiOptions = {
  title: "You are signing a Glider Session Key",
  description:
    "This message is required to authenticate ownership of the strategy and provide Glider access to manage the assets within the strategy.",
  buttonText: "Sign",
};

// Sign the message with the owner's wallet
const signature = await signMessage(
  {
    message: messageToSign,
  },
  {
    uiOptions,
    address: wallet.address,
  }
);

​
Funding a Portfolio with Privy

Funding a portfolio is done by sending funds to a portfolio’s vault address. Follow along with Privy’s docs on sending a transaction for your specific situation.

1

Get the Portfolio's Vault Address

Fetch the portfolio’s vault address by calling the https://api.glider.fi/v1/portfolio/{portfolioId} endpoint.

2

Send Funds to the Portfolio's Vault

import { useSendTransaction } from "@privy/react-auth";
import { formatEther } from "viem";

const { sendTransaction } = useSendTransaction();

// Send 0.2 ETH to the portfolio's vault address
sendTransaction({
  to: "0xE3070d3e4309afA3bC9a6b057685743CF42da77C",
  value: formatEther(0.2),
});

​
EVM Smart Wallets

Privy provides support for EVM smart wallets. However, smart wallets as owners of portfolios are not yet supported by Glider.

​
Interfacing with Viem

An alternative to using Privy’s SDKs is to use Viem for funding and message signing. Privy provides a tutorial on interfacing with Viem. By creating a Wallet Client you’ll be able to sign messages and send transactions for the portfolio owner.
