Markets

Every market. One model.

Five asset classes share a single instrument, order and position model — so adding a market never means rebuilding the app.

Platform

Everything a modern trading app needs.

Built as modular layers, so each provider can change without rebuilding the experience.

How it works

From sign-in to settled position.

The full path a user takes — and exactly where identity, custody, collateral and execution responsibilities sit.

  1. Sign in with Privy

    Email or social login. The server verifies the session token and maps the identity to an internal account — browser-supplied user IDs are never trusted.

  2. Embedded wallet, provisioned

    A self-custodial wallet is created at sign-in. Fintech Street stores only the public address — never keys or recovery material.

  3. Simulated collateral, kept separate

    Your trading account receives explicitly simulated USD, recorded in a double-entry ledger that never mixes with on-chain wallet assets.

  4. Trade on live market data

    Orders are validated server-side, checked against collateral and risk limits, and filled idempotently against identified, timestamped prices.

  5. Positions, P&L and audit trail

    Fills update positions, margin and P&L under documented rules. Every balance change is a ledger entry with an audit event.

Separation of funds

Three balances. Never blended.

Wallet ownership, trading collateral and venue margin have different owners and risks. Fintech Street keeps them separate in the data model and on screen.
