Fractional US Stock Investing on Web3 Rails: The Alpaca SDK
By Investing Team · June 5, 2026 · 4 min read
Unifying your assets
For most users, cash, stablecoins, crypto and stocks are scattered across different apps (Chase, Coinbase, Robinhood). This fragmentation makes it hard to track true net worth or move funds when markets shift. Furlpay solves it by bringing fractional stock investing directly into your Web3 dashboard.
Embedded brokerage-as-a-service
Furlpay integrates the Alpaca Brokerage-as-a-Service API to enable seamless equity trading:
- Fractional shares: buy as little as $1 of common stocks and ETFs (AAPL, TSLA, SPY).
- Instant funding: sell stablecoins in your wallet and buy stocks immediately, without waiting for T+2 settlement.
// Purchase fractional stock via Furlpay's investing client
const order = await furlpay.investing.placeOrder({
symbol: 'AAPL',
notional: 10.00, // buy exactly $10 of Apple stock
side: 'buy',
type: 'market'
});All accounts are opened directly with Alpaca Securities LLC, a regulated SEC broker-dealer, so your investments are protected by SIPC.
