-
Transient Storage (EIP-1153): Single-transaction reentrancy guards reducing lock overhead from 2,100 gas (
sstore) to 100 gas (tstore), intra-tx fee accumulators, and zero-storage transient routers. -
Yul Inline Assembly: Custom memory bump allocators bypassing standard Solidity memory expansion penalties, high-performance function selector jump tables, and bitwise fixed-point WAD (
$10^{18}$ ) / RAY ($10^{27}$ ) arithmetic. - Storage Engineering: Multi-variable bit-packing into single 32-byte slots and ERC-7201 formulaic namespaced storage collision detectors.
- Anti-LVR Mechanics: Continuous tick displacement tracking and exponential half-life volatility decay curves dynamically adjusting pool fee tiers to capture toxic flow as LP yields.
-
Concentrated & Multi-Asset AMMs: Uniswap v3
$Q64.96$ tick ranges, Balancer generalized geometric invariant pools ($\prod B_i^{w_i} = k$ ), and Curve Newton-Raphson amplification pools. - Lending & Margin Markets: Overcollateralized CDP stablecoin minters, isolated peer-to-peer agreements, Dutch auction liquidation engines, and multi-collateral margin baskets.
- ERC-4337 & ERC-7579: Modular smart accounts, gas sponsorship verifying paymasters, scoped temporary session key plugins, and pre-execution spending guardian policy hooks.
- Biometric & Off-Chain Verification: WebAuthn / Passkey P-256 (secp256r1) signature verification, EIP-712 structured meta-transactions, and blind signature anonymous ballot schemes.
- Zero-Knowledge & Privacy Primitives: Groth16 zk-SNARK pairing checks on the alt_bn128 curve (
0x08precompile), and cryptographic commitment-nullifier privacy mixers.
All protocol repositories enforce:
- Strict Invariant Property Testing: State machine fuzzing via Foundry (
--runs 256to10,000+). - Cancun EVM Compatibility: Tested and verified against Ethereum Cancun hardfork opcodes (
evm_version = "cancun"). - Formal Code Formatting: Standardized via
forge fmt. - Zero External Baggage: Self-contained, custom-error driven contracts designed for gas minimization and audit readiness.
