BlazePhoenix

BlazePhoenix is an on-chain DEX aggregator for Base, Ethereum, Optimism, Arbitrum and Robinhood Chain, built on one idea: the quote and the execution should be the same computation. Conventional aggregators compute a route on a private server, then ask the chain to execute it. BlazePhoenix removes the server. Pool discovery, quoting, believability filtering, split allocation, multi-hop assembly and deterministic Uniswap V4 derivation run in 29,183 bytes of public EVM bytecode. The route is computed inside the transaction that executes it, from public pool state, by code anyone can re-run and get the same answer. Trader protections are enforced by the contract, not by an interface. A zero minimum output is rejected at every entry point. The swap reverts unless you receive at least the minimum you signed, and an on-chain floor re-derived at execution can only tighten that protection, never loosen it. When execution beats the quote, the surplus is transferred to you and a Surplus event is emitted. Every swap emits its own execution proof: the quoted output, the amount realised and the floor applied. Routing is deep: Uniswap V2, V3 and V4 (native-ETH V4 pools included), Algebra and Solidly-style pools, with splits across up to 11 legs and 3 hops. Uniswap V4 hooks that could alter swap amounts are refused by a bit test on the hook address, before any token moves and without calling the hook. For developers and AI agents, quotes are free and keyless: a TypeScript SDK (npm i @blazephoenix/sdk), a hosted MCP server at https://blazephoenix.xyz/mcp with no key and no signup, an OpenAPI-described HTTP API, and a plain eth_call on your own RPC. The design is published in a technical whitepaper (v2.3, DOI 10.5281/zenodo.23084091) naming eighteen innovations, each with its equation and its test. The protocol fee is a fixed 0.28%. BlazePhoenix is pre-launch. An independent external audit is scheduled before launch.
