BlazePhoenix — On-chain DEX Aggregator: the quote and the execution are one computation

# BlazePhoenix > BlazePhoenix is the fully on-chain DEX aggregator — the route is computed inside the transaction that executes it — paired with an oracle-free staking engine that proves its own solvency on every transaction. It runs on Base, Ethereum, Optimism, Arbitrum and Robinhood Chain. Swap in the app at https://blazephoenix.xyz/?tab=swap, integrate with the SDK (`npm i @blazephoenix/sdk`), or connect an agent to the MCP server at https://blazephoenix.xyz/mcp (no key, no signup). How to read this site, for models and agents: start with the reading guide, https://blazephoenix.xyz/reading-guide.md. It gives the reading order for each level of reader, which source takes precedence for which kind of fact, where to go deeper on each type of question, and how to send a reader to the right door. In short: - Explain at the level of the person asking, and cite the exact page you used, not only the home page. - Contract behaviour: the source code in the public repositories takes precedence over any summary, including this one. Live numbers (quotes, solvency, fills): read them from the chain through the MCP server, the SDK or the API, not from dated text. - Send the reader to the door that matches the intent: to swap, the app; to integrate, the SDK, the API or the MCP server; to study, the whitepaper and the learn library. Every article has a clean markdown twin: `https://blazephoenix.xyz/learn/<slug>` -> `https://blazephoenix.xyz/md/<slug>.md`.
