The Obol Stack

The Obol Stack is a Kubernetes-based operating environment that gives AI agents first-class access to the Ethereum economy. Instead of wrapping cloud APIs, the agent runs alongside its own infrastructure: RPC gateways, a container-isolated signing key, x402 payment rails, and a Cloudflare tunnel to the public internet. This is not an app built during a hackathon — it is the *environment* that makes every Ethereum agent app possible. **What runs in this cluster:** - **eRPC gateway** connected to Ethereum mainnet, Base, Base Sepolia, and Hoodi — no Infura keys, no rate limits, no third-party dependency once we sync full nodes for each - **Remote signer** holding an Ethereum key (0x210f...0F5e) that the agent can use to sign transactions but can *never* extract the private key from — architectural security, not policy security - **Foundry/cast** installed natively for ABI-decoded contract reads, ENS resolution, and raw JSON-RPC - **x402 sell infrastructure** — Agent simply creates a ServiceOffer CRD and the reconciler wires the Traefik middleware, payment gating, public route, and optional ERC-8004 registration automatically. The agent creates businesses by writing YAML. - **x402 buy infrastructure** — pre-sign bounded USDC authorizations stored in ConfigMaps. A Go sidecar handles payments at runtime with zero signer access. Max loss = N × price by design, not by trust. - **Cloudflare tunnel** exposing services to the internet — the agent does not just build things, it serves them to the world - **16 Ethereum-specific skills** covering: verified contract addresses, DeFi composability (Aerodrome, GMX, Pendle, Velodrome), L2 ecosystem knowledge, ERC-8004 agent discovery, gas economics, distributed validator monitoring, and mental models that correct what LLMs typically get wrong about onchain systems **The economic loop:** An agent in this environment can discover other agents on-chain → buy inference from them via x402 → build and deploy its own services → price them with micropayments → expose them publicly → earn revenue → spend that revenue on more inference. Both sides of the market, risk-bounded, with on-chain receipts. **Why this matters for agents specifically:** A human developer can use Infura and MetaMask. An AI agent cannot click browser extensions or manage API key dashboards. The Obol Stack removes every dependency that assumes a human in the loop — the agent has direct, programmatic access to everything it needs to operate as an independent economic actor on Ethereum.
