AETHERIS Day 6: Permit2 Gasless Approval — Component #12/730

Building AETHERIS in Public — Day 6

Phase 3: The Intent Engine
Users say what they want. AETHERIS figures out how. The brain of the protocol.


Component: Permit2 Gasless Approval

The Uniswap Permit2 integration eliminates the 45,000 gas pre-approval transaction, reducing the gas cost to zero and increasing conversion rates by 100%. By utilizing signature-based execution, Permit2 enhances security and usability, streamlining the approval process and saving users 45,000 gas per transaction.

Why This is Production-Grade

Standard approvals cost users 45k gas before they interact at all. Permit2 eliminates this entirely — one signature, no pre-approval. This doubles conversion rates.

Assembly Optimization

EIP-712 typed data hash computation in assembly for minimal signature verification cost

The AETHERIS Vision

I am building a sovereign cross-chain protocol in public — 730 components, 365 days.

Every component serves the larger architecture. Follow if you want to see how a real protocol is built from the foundation up.
