SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Ethereum tooling changes fast, and outdated knowledge leads developers and AI agents to deprecated frameworks, dead testnets, and wrong workflows. This Skill provides a current, verified reference of what actually works for building on Ethereum today. ## Core Features & Use Cases - Tool Selection Guidance: Compares Foundry, Hardhat 3, Scaffold-ETH 2, viem, and wagmi so you pick the right stack for contract-focused or full-stack dApp work. - Agent Integration Patterns: Documents Blockscout MCP for structured blockchain reads, abi.ninja for zero-setup contract interaction, and x402 SDKs for HTTP payments. - Operational Reference: Lists RPC providers, block explorers, Sepolia faucets, and essential cast commands for reading, sending, and testing against forked mainnet. - Use Case: An AI agent needs to query a contract on Base. Instead of scraping Etherscan, it uses the Blockscout MCP server for structured data and abi.ninja to explore the contract's functions. ## Quick Start Ask the agent to recommend an Ethereum development stack and show how to read a contract's balance using cast and a free RPC endpoint.

FAQPage Schema
How do I choose between Foundry and Hardhat for Ethereum development?▼

Foundry is faster and Solidity-native, making it the default for contract-focused work. Hardhat 3 is TypeScript-first with a mature plugin ecosystem and shipped Solidity testing and fuzzing in August 2025, making both legitimate choices in 2026.

How can an AI agent read blockchain data without scraping Etherscan?▼

Use the Blockscout MCP server at https://mcp.blockscout.com/mcp, which gives agents structured, type-safe blockchain data via the Model Context Protocol. It supports transactions, addresses, token balances, and contract queries across multiple chains.

What is the fastest way to interact with a deployed smart contract?▼

Paste the contract address into abi.ninja to get a UI for calling any verified function with zero setup, or use `cast call` and `cast send` from the Foundry CLI for scripted read and write operations.

Which Ethereum testnet should I use and where do I get test ETH?▼

Sepolia (Chain ID 11155111) is the primary testnet; Goerli and Rinkeby are deprecated. Get Sepolia ETH from faucets like sepolia-faucet.pk910.de, Alchemy, QuickNode, or Infura, then bridge to L2 testnets.

How do I test against real mainnet contracts locally?▼

Run `anvil --fork-url https://eth.llamarpc.com` to fork mainnet locally. This gives you a local node at http://localhost:8545 with real contract state and fake ETH for testing.

Does x402 have production-ready SDKs for HTTP payments?▼

Yes, x402 has production SDKs: `@x402/fetch` for TypeScript, the `x402` package for Python, and `github.com/coinbase/x402/go` for Go. Documentation is at x402.org and the Coinbase GitHub repository.
