@segmento/lead

Solana wallet signing for the Segmento SDK. Prompts the user to sign a waitlist message and returns a verifiable payload.

Installation

npm install @segmento/lead

Usage

import { signMessage, getSignMessage } from "@segmento/lead";

// Sign with the connected wallet
const payload = await signMessage(wallet, "My Project");

console.log(payload.address);   // base58 wallet address
console.log(payload.message);   // the message that was signed
console.log(payload.signature); // base58-encoded signature
console.log(payload.ts);        // Unix timestamp (ms)

The signed message follows the format:

I am signing up to the {projectName} waitlist. By signing this message I confirm
that I have read and agree to the Terms and Conditions: {tc_url}

Wallet adapter

Pass any object that implements:

interface WalletAdapter {
  publicKey: { toBase58(): string } | null;
  signMessage(message: Uint8Array): Promise<Uint8Array>;
}

Compatible with @solana/wallet-adapter-base and the Phantom window.solana provider:

const wallet = {
  publicKey: { toBase58: () => phantomResp.publicKey.toBase58() },
  signMessage: (bytes) => phantom.signMessage(bytes, "utf8").then(r => r.signature),
};
