Build on Rubin — Embed a Crypto Exchange, SDK & MCP API

Rubin Builder lets developers, integrators, and brokers embed a full self-custody decentralized exchange — perpetual futures and spot — into any product. Drop in an iframe widget, build with the trading SDK, or connect an MCP server for AI-agent trading. Configure it visually, publish to your own subdomain or custom domain, and earn builder fees on the flow you bring.

Embed in minutes

Configure a Rubin trading widget visually and drop a copy-paste iframe snippet into your website, app, or portal. Themeable, responsive, and self-custody by default — your users trade from their own wallet. See the embed configurator.

Build with the SDK

Integrate programmatically with the Rubin trading SDK and REST/WebSocket API: place and manage orders, stream market data, read positions and balances. Full developer docs at SDK docs.

AI-agent trading (MCP)

Connect AI agents and assistants to Rubin's MCP server — let bots and AI workflows place orders, read order books and candles, and manage positions through a standard tool interface. See MCP & AI trading.

Publish & earn

Publish your configured exchange to a Rubin subdomain or your own custom domain, and earn builder fees on the order flow you route. For brokers and integrators bringing volume.
