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 |
|---|---|---|
| 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 |
| evm-state-anchor-audit | Python | Compare EVM RPC providers using block hashes and EIP-1898 state reads to find lag, inconsistent data and unsupported historical queries |
| evm-commitment-auditor | Python | Recompute EVM transaction, receipt, and log bloom commitments from JSON-RPC responses. |
| paymaster-runway-check | Python | Estimate how long each ERC-4337 paymaster can keep sponsoring UserOperations from its EntryPoint deposit, using UserOperationEvent logs and getDepositInfo over JSON-RPC. |
| safe-multisig-inspector | Python | Inspect a Safe multisig on-chain: version, owners and threshold, nonce, modules, guard and fallback handler |
| erc165-interface-auditor | Python | Read-only ERC-165 matrix audit for NFT interface claims, control-ID behavior, empty returns, and custom interface IDs over JSON-RPC. |
| create2-deploy-rehearsal | Python | Rehearse CREATE2 deployments through the deterministic deployment proxy without sending a transaction. |
| userop-hash-recheck | Python | Recompute ERC-4337 userOpHash values from a handleOps transaction's calldata and verify them against the EntryPoint's UserOperationEvent logs (v0.6 to v0.8) using only JSON-RPC. |
| evm-log-range-probe | Python | Measure filter-specific eth_getLogs range limits across multiple EVM JSON-RPC providers. |
| timelock-queue-audit | Python | Audit Compound Timelock queue entries from RPC logs and on-chain state. |
