DEX Aggregation Is Harder Than You Think

" summary

Argon routing engine and the new 0x API V2 claim to cut false-positive quotes and handle crazy multi-hop routes like a $50k MATIC, $400k PEPE and $1.8M trade on Arbitrum while measuring latency and MEV risk. Architecture uses permit2 architecture plus an allowance holder contract to permit biweekly upgrades and safer ephemeral approvals, adds four chains since launch with six–seven planned, supports fee-on-transfer tokens, offers precise gas estimates and an issues field, and asserts it delivers the best quote accuracy through simulation and stricter quote validation.
