This CLI tool wraps Stellar's simulateTransaction RPC to report real resource consumption (CPU instructions, memory, read/write entries/bytes, tx size, rent) and the fee in stroops/XLM for your compiled Soroban contract .wasm files.
Gas estimator for MegaETH. Shows dual gas costs (compute + storage), compares MegaETH vs Ethereum L1. Critical: MegaETH minimum gas is 60,000, not 21,000.
Deterministic blockchain utilities for AI agents - gas estimation, outcome verification, and conditional USDC escrow on Base that settles only when an independent verifier confirms the outcome. Public track record: logicnodes.io/transparency
A fully custom-built Ethereum wallet. Features wallet creation/import, raw transaction handling, BIP-39 mnemonic generation, secure storage, and seamless network switching. Built with React, Material UI, Ethereumjs-util, and Alchemy-powered nodes, supporting multiple Ethereum and Polygon networks.
A robust Node.js utility for tracking and estimating resource costs ("gas") during asynchronous function execution. Gas2nel monitors CPU usage, memory allocation, network I/O, and file system operations to provide realistic resource utilization metrics.
MCP server for fee recommendations and gas estimation on EVM, UTXO, and XRP blockchains via Crypto APIs
