Live onRobinhood Chain

Stocks are now Tokens.RailX gives developers and agents the execution layer to build what comes next.

The biggest market in the world is moving onchain.

  • NVDA
  • AAPL
  • TSLA
  • NFLX
  • MSFT
  • AMZN
  • GOOGL
  • META

Stocks can now move through wallets and smart contracts. Building around them still means stitching together asset data, prices, liquidity, approvals, and chain simulation. RailX turns that stack into one developer interface.

Test every trade before you sign it.

RailX builds the transactions, tests the full sequence onchain, and sends a ready-to-sign plan to your wallet.

Your wallet stays in control

One clear contract, all the way through.

Use TypeScript, plain HTTP, or the OpenAPI specification. Every response includes the route, ordered transactions, simulation result, and the data your wallet needs to sign.

The hard parts around every trade are already handled.

Test safely, control production access, trace every request, and keep signing in the user's wallet.

The wallet stays in control

RailX returns unsigned transactions. It never holds funds, keys, or signing authority.

Built for coding agents.

Give your agent one documented interface for market data, transaction building, safety checks, and simulation.

Build with RailX
A request passing through four verification gates before becoming an unsigned transaction plan
One request. Four checks. An unsigned plan the wallet can inspect.
