Introduction to the Obol Stack

The Obol Stack is a local-first agent harness: a Kubernetes cluster on your laptop, a default AI agent (Hermes) with its own Ethereum wallet, dynamically-deployable blockchain networks, a Cloudflare tunnel for public exposure, and an x402 payment gateway so agents can charge for what they serve.

The thesis is simple: agents should be able to run real infrastructure, build something valuable on top of it, and sell access to it for micropayments — without asking permission and without standing up cloud accounts.

info

The Obol Stack is alpha software. For production validator deployments, use the Run a DV docs and dedicated infrastructure.

What's in the box

Obol Stack is a two-part system:

1. obolup.sh — bootstrap installer that lays down pinned dependencies (kubectl, helm, k3d, helmfile, k9s) and the obol CLI.
2. obol CLI — Go binary that drives everything: cluster lifecycle, the agent, networks, payment-gated services, and the tunnel.

The cluster runs entirely on your machine via k3d (Kubernetes in Docker).

Key features

• Agent-first — obol stack up brings up a default Hermes agent with its own Ethereum signing wallet (backed by a remote-signer), a chat TUI, and a growing skill set. Talk to it with obol hermes chat.
• Sell what your agent builds — obol sell demo deploys a payment-gated HTTP service in one command. Use it as the starting point for selling inference, indexed data, or any HTTP API for $OBOL or USDC micropayments.
• Native $OBOL micropayments with sponsored gas on mainnet — when buyers pay in $OBOL on Ethereum mainnet, the Obol facilitator sponsors the on-chain settlement gas. Buyers sign an EIP-2612 permit off-chain and never need ETH. Sellers receive $OBOL directly to their agent wallet.
• Multiple network support — sync local Ethereum nodes (mainnet, sepolia, hoodi), Aztec sequencers, and more. Built-in eRPC routes to public RPCs when no local node is present.
• Public access — expose only the routes you choose (/services/<name>/* and discovery metadata) via a Cloudflare quick tunnel. Internal routes (frontend, eRPC) stay locked to obol.stack.
• Unique deployments — every install gets a uniquely-namespaced deployment, so multiple stacks coexist on one machine.

CLI overview

Command	Description
obol stack init / up / down / purge	Cluster lifecycle
obol agent init / new / setup / sync / list / delete	Manage agent instances (default runtime: Hermes)
obol hermes chat / skills / config / ...	Pass-through to the in-cluster Hermes CLI
obol model setup / status	Configure LLM providers (Ollama, Anthropic, OpenAI, custom)
obol network list / install / sync / delete	Manage blockchain networks
obol sell demo / inference / http / list / status / register	Create payment-gated services and register on ERC-8004
obol app install / sync / list / delete	Install arbitrary Helm charts
obol tunnel status / setup / restart	Manage the Cloudflare tunnel (setup creates a permanent URL)
obol kubectl / helm / helmfile / k9s	Kubernetes tool passthroughs (auto-configured KUBECONFIG)

Default infrastructure

When you run obol stack up, the following services are deployed automatically:

Service	Namespace	Purpose
Hermes (default agent)	hermes-obol-agent	AI agent + dashboard, with its own Ethereum signing wallet
Traefik	traefik	Gateway API ingress controller
Cloudflared	traefik	Cloudflare tunnel connector for public routes
eRPC	erpc	Unified RPC load balancer (local nodes + public fallbacks)
Obol Frontend	obol-frontend	Web management dashboard (local-only)
Monitoring	monitoring	Prometheus + kube-prometheus-stack
LiteLLM	llm	OpenAI-compatible LLM gateway (Ollama, Anthropic, OpenAI, custom endpoints)
x402 verifier + ServiceOffer controller	x402	Payment gating + reconciliation of payment-gated services

Use it from Claude Code

The Obol team publishes a Claude Code plugin with skills for installing, operating, and selling on the Obol Stack.

/plugin marketplace add ObolNetwork/skills
/plugin install obol@obol

Once installed, Claude Code can drive obol stack up, set up the agent, troubleshoot pods, and walk you through obol sell demo. Source: github.com/ObolNetwork/skills.

System requirements

Prerequisites

• Docker 20.10.0 or later (daemon must be running)
• macOS (Darwin) or Linux
• amd64 or arm64 architecture

Resource recommendations

Component	Minimum	Recommended
CPU	4 cores	8 cores
RAM	8 GB	16 GB
Storage	50 GB	500+ GB (varies by network)

warning

Running full Ethereum nodes requires significant disk space. Mainnet execution clients can require 1+ TB of storage.

Where next

• Quickstart — install the stack, talk to your agent, and run obol sell demo.
• Build a profitable Obol Stack — end-to-end: bounded archive node → index → paid service → specialized agent → listed on marketplaces.
• Selling agent services — full orientation on the three sell shapes, x402 economics, ERC-8004 registration, and Telegram notifications.
• Installing Networks — sync Ethereum / Aztec, including bounded archives via --since.
