Overview

Pollar is the onboarding-to-payment infrastructure layer for consumer apps on Stellar. The full stack that takes a new user from clicking Continue with Google to sending USDC — without ever showing them a seed phrase, a wallet address, a transaction fee, or a trustline prompt.

The problem

Every team building a consumer product on Stellar hits the same infrastructure wall before writing a single line of their actual product:

• Creating or linking a Stellar account for each user

• Handling XLM reserve funding

• Configuring trustlines for each asset

• Abstracting transaction fees from users unfamiliar with blockchain

• Building an onboarding flow that works for people with zero crypto experience

Pollar handles all of this so you can skip straight to building your product.

The solution

import { PollarProvider, usePollar } from '@pollar/react';

function App() {
  const { isAuthenticated, login, runTx } = usePollar();

  if (!isAuthenticated) {
    return (
      <button onClick={() => login({ provider: 'google' })}>
        Continue with Google
      </button>
    );
  }

  return (
    <button
      onClick={() =>
        runTx('payment', {
          destination: 'GXXX...',
          amount: '10',
          asset: { type: 'credit_alphanum4', code: 'USDC', issuer: 'GA5Z...' },
        })
      }
    >
      Send 10 USDC
    </button>
  );
}

export default function Root() {
  return (
    <PollarProvider client={{ apiKey: 'pub_testnet_...' }}>
      <App />
    </PollarProvider>
  );
}

In a handful of lines: OAuth authentication, a funded Stellar wallet, and USDC payments. No seed phrases. No fee prompts. No trustline configuration. (runTx is the one-shot build → sign → submit helper; see the SDK Reference for the split buildTx / signAndSubmitTx flow.)

How it compares

Pollar also integrates with several of these: first-party adapters let you use Privy embedded wallets or any Stellar Wallets Kit wallet as a login method on top of Pollar's stack. See Wallet Adapters.
