The Execution Layer
IoTAI's gas-optimized execution architecture for maximum trading efficiency.
Introduction
The Execution Layer is where all trades are processed through our single-entry router architecture. This layer eliminates the gas overhead of traditional DEX aggregators while maintaining access to liquidity from major protocols.
Single-Entry Execution Model
Traditional DEX aggregators route trades through multiple contracts, creating unnecessary gas consumption. IoTAI consolidates all swap logic into a single router entry point that executes the full hop sequence internally.
Eliminates intermediate calls to third-party aggregator proxies
Reduces redundant ABI encoding/decoding operations
Minimizes context switching between contracts
Aggregates liquidity from 0x, 1inch, and Paraswap without routing overhead
Adapter Layer Architecture
DEX integrations are implemented as lightweight adapters that conform to a shared interface. The router invokes these adapters via low-level calls, thereby avoiding the expense of higher-level Solidity abstractions.
Shared libraries are inlined once, minimizing duplicated bytecode
Low-level calls (call/delegatecall) reduce execution overhead
A uniform interface ensures consistency across integrations
Modular design allows easy addition of new DEX protocols
Off-Chain Pathfinding
Route discovery and optimization occur entirely off-chain. The on-chain component receives precomputed calldata and executes it verbatim, with no graph traversal or dynamic branching.
Removes loops and complex control flow from EVM execution
Dramatically reduces instruction count and gas consumption
Ensures optimal routing decisions before execution
Eliminates costly on-chain computations
Memory-Optimized Operations
The router operates primarily in memory, issuing minimal SSTORE operations. Event logging is likewise minimized to reduce gas costs.
Critical execution paths use inline assembly when safe
Bypasses unnecessary Solidity safety checks
Compact data structures reduce transaction size
Storage writes and event emissions are minimized
Call Data Tightening & Inline Assembly
Critical optimization techniques for maximum execution efficiency.
Compact Calldata Structures
Call data structures are hand-crafted to be compact
Custom encoding reduces transaction size and gas costs
Optimized parameter packing minimizes data overhead
Inline Assembly Optimization
Critical execution paths use inline assembly when safe
Bypasses Solidity's automatic safety checks when provably unnecessary
Further shrinks bytecode size and execution overhead
