Fintech Street is a simulated trading architecture platform by Realtime Software Inc. It shows how identity, embedded wallets, market data, order management and external trading providers come together in one product.
Privy authenticates the user and provisions a self-custodial embedded wallet. The server verifies every session token and maps the Privy identity to an internal account. Only public addresses are stored — never keys or recovery material. A wallet-provider abstraction lets Turnkey or another authorized provider slot in later.
Provider adapters translate each venue’s feed into one normalized instrument, quote, order book and candle model. Every value carries provenance — provider, mode and timestamp — so simulated or stale data can never pass as live. Perpetuals stream from Kraken Futures public data today.
Orders are validated on the server, checked against collateral and risk limits, and processed idempotently. Fills update positions, margin and P&L under documented, deterministic rules. Every balance change is a double-entry journal that must net to zero, with an append-only audit trail.
Fintech Street demonstrates how Realtime Software can help a brokerage add trading to its own products: broker account mapping, funding workflows, order routing, position sync, pre-trade risk checks and integration health — each behind a capability-driven adapter contract.
The full path a user takes — and exactly where identity, custody, collateral and execution responsibilities sit.
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.
A self-custodial wallet is created at sign-in. Fintech Street stores only the public address — never keys or recovery material.
Your trading account receives explicitly simulated USD, recorded in a double-entry ledger that never mixes with on-chain wallet assets.
Orders are validated server-side, checked against collateral and risk limits, and filled idempotently against identified, timestamped prices.
Fills update positions, margin and P&L under documented rules. Every balance change is a ledger entry with an audit event.
Every provider sits behind an adapter with an explicit capability matrix. Hover a component, or pick a capability, to trace it.
