Ethereum and DeFi tooling in Python, Go, TypeScript, Solidity and Rust. Most of it reads data from the chain over JSON-RPC: AMM and gas math, contract state, EVM internals.
- univ3-tick-math: Uniswap v3 tick, price and sqrtPriceX96 conversions
- matching-engine-go: limit order book with price-time priority
- eth-checksum-address: EIP-55 checksums with a pure-Python Keccak-256
| Project | Language | Description |
|---|---|---|
| eip7702-auth-audit | Python | Audit EIP-7702 type-4 transactions by decoding authorization tuples, recovering senders, and checking delegation state through JSON-RPC. |
| pr-inbox | Python | See what people said on your pull requests to other projects since you last looked: new human reviews and comments, merges and closes, without bot noise |
| proxy-upgrade-ledger | Python | Rebuild an upgradeable proxy's admin, implementation and beacon history from Upgraded/AdminChanged logs and check it against the live EIP-1967 slots over plain JSON-RPC. |
| evm-state-proof-auditor | Python | Verify EVM account and storage proofs returned by eth_getProof against a block state root. |
| withdrawal-log-gap | Python | Detect missing OP Stack MessagePassed withdrawal logs by reconciling nonce state, event hashes, and sentMessages through JSON-RPC. |
| solana-stake-lockup-gate | Python | Check whether a Solana stake withdrawal signer passes authority and lockup gates using one RPC snapshot |
| selector-shadow-map | Python | Find Solidity-style dispatcher selector collisions between two deployed EVM runtimes using JSON-RPC bytecode |
| role-ledger | Python | Rebuild OpenZeppelin AccessControl role holders from RoleGranted/RoleRevoked logs, verify them with hasRole and getRoleMember, and flag risky admin setups over plain JSON-RPC. |
| bip32-path-tool | Python | Parse, validate and explain BIP32/BIP44 derivation paths, and generate address-index ranges |
| erc1155-supply-audit | Python | Reconcile ERC-1155 mint and burn logs with totalSupply for one token ID using only EVM JSON-RPC. |
| erc20-transfer-policy-probe | Python | Read-only ERC-20 transfer probes that classify accepted, false, and reverted calls across amounts with optional JSON-RPC state overrides. |
| oracle-round-audit | Python | Audit Chainlink AggregatorV3 proxy rounds for staleness, gaps, abnormal moves, and aggregator changes using only EVM JSON-RPC. |
| solana-alt-gate | Python | Check whether a Solana address lookup table and requested indexes are usable in one RPC snapshot |
| arb-batch-status | Python | Show which sequencer batch holds an Arbitrum block or transaction, its L1 confirmations, and whether it is below the safe and finalized heads, using only JSON-RPC and NodeInterface |
| evm-cbor-audit | Python | Decode Solidity CBOR metadata trailers from deployed EVM bytecode using only JSON-RPC |
