Description
Problem
ABI encoding/decoding is complex but only has unit tests. Property-based testing would catch edge cases.
Location
src/core/abi.ts
Recommendation
Add fast-check property tests for:
- encode/decode round-trip for all types
- Random nested arrays
- Edge cases: max uint256, empty arrays, long strings
- Comparison with reference implementation (ethers/viem)
Priority
Testing - Coverage for complex logic

Research direction
Start with src/core/abi.ts and its existing unit tests to understand the ABI encoding and decoding cases already covered. Add fast-check properties for round trips, nested arrays, and the listed edge cases, then compare results with ethers or viem. Done means the property tests run reliably and cover the recommended cases.
