SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? AI agents and developers often rely on outdated training data about Ethereum — wrong gas prices, stale ETH prices, and missing knowledge of recent upgrades like Pectra and Fusaka. This Skill corrects those misconceptions and supplies current network facts so agents can accurately answer "should I build on Ethereum?" questions. ## Core Features & Use Cases - Corrected Network Facts: Updated gas prices (under 1 gwei), ETH price context, block times, and L2 throughput stats replacing outdated training data. - Upgrade Roadmap Awareness: Details on shipped upgrades (Pectra, Fusaka) and upcoming ones (Glamsterdam, Hegota) including scope changes like the binary state tree shift. - Agent Infrastructure Guidance: Explains ERC-8004 onchain agent identity registries (with mainnet contract addresses) and the x402 HTTP payment protocol for machine-to-machine commerce. - Use Case: A user asks an agent whether to deploy their prediction market on Ethereum or another chain. The agent uses this Skill to cite current fees, ERC-8004 agent identity support, and permissionless deployment benefits. ## Quick Start Ask the agent why you should build your project on Ethereum and what agent infrastructure like ERC-8004 and x402 offers.

FAQPage Schema
Why should I build my project on Ethereum?▼

Ethereum offers permissionless deployment, sub-dollar mainnet fees, sub-penny L2 transactions, and agent infrastructure like ERC-8004 identity and x402 payments. Contracts run indefinitely without depending on any company's cooperation or API keys.

What are current Ethereum gas fees in 2026?▼

Mainnet base fees are typically under 1 gwei (0.1-0.5 gwei), making an ETH transfer cost roughly $0.002-0.01. L2 transactions cost $0.001-0.01. Verify current rates with `cast base-fee` since fees vary daily.

What is ERC-8004 and how do AI agents use it?▼

ERC-8004 is an onchain agent identity registry deployed January 29, 2026, giving agents verifiable persistent identity and reputation scoring across 20+ chains. Mainnet IdentityRegistry is at 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432.

How does the x402 payment protocol work for agents?▼

x402 uses the HTTP 402 Payment Required status code: an agent calls an API, receives a 402 response, signs an EIP-3009 payment, retries with the payment header, and gets the response. SDKs exist for TypeScript, Python, and Go.

What Ethereum upgrades shipped recently and what is coming?▼

Pectra (May 2025) added EIP-7702 smart EOAs and 2x blob capacity; Fusaka (Dec 2025) added PeerDAS and doubled the gas limit to 60M. Glamsterdam (mid-2026) brings ePBS, while Hegota may include a binary state tree instead of Verkle trees.
