BlazePhoenix routes your WETH → SPX swap across the deepest pools on Base — and unlike a normal aggregator, the quote itself is computed on-chain by the Quoter contract. There is no off-chain pricing API to trust: the number you see is produced by the same machinery that executes the trade.
✅ Surplus to you — if execution beats the quote, the difference is returned, fee-exempt (in the contract, not the marketing).
✅ Phantom-liquidity protection — every quote is capacity-clamped to pools' real holdings, so thin pools can't promise tokens they don't have.
✅ Self-custodial, no KYC — connect a wallet and trade; nothing to sign up for.
✅ Verifiable — staking solvency, contracts and every fill are publicly checkable on-chain (live proof).
🔍 Check before you trade — run SPX through the free Pool X-Ray to compare advertised liquidity against what the pools actually hold on-chain.
