v0.9.0 — $OBOL is money

The obol or obolus (Ancient Greek: ὀβολός) was a form of ancient Greek currency and weight. - Wikipedia

This release introduces the Hermes agent framework by NousResearch, along with support for $OBOL gasless payments on mainnet in obol sell commands, and introduces some demo services to sell for new users to quickly host some sample local agent services they can iterate on later.

Get started selling services from your stack with obol sell demo. Tag @Obol_Collective on X with your storefront and maybe we'll check it out.

Release Highlights

🤝 obol sell demo — your first paid endpoint, in one command

The headline of v0.9.0 obol sell demo deploys a small HTTP service into the cluster, gates it behind x402, registers it on a Cloudflare quick tunnel, waits for the offer to reach Ready=True, and prints copy-paste try-it instructions for both curl and the Python x402 SDK.

obol sell demo                    # hello @ 1 OBOL/req on Ethereum mainnet

Use it as the canonical "Hello World" for agent commerce. Once you've watched a paid request settle end-to-end, the same machinery (obol sell inference / obol sell http) wraps anything in your cluster.

💸 $OBOL micropayments with sponsored gas on mainnet

Buyers paying in $OBOL on Ethereum mainnet sign an EIP-2612 permit off-chain. The Obol-operated x402 facilitator (x402.gcp.obol.tech) batches that permit with the on-chain transfer at settlement time. Buyers never spend ETH on gas and skip the one-time approve(Permit2, max) step that most ERC-20 payment flows require. Sellers receive $OBOL directly into their agent wallet.

This is the most concretely better-than-card UX the stack ships: sign a message, pay in OBOL, neither party touches a gas token. Combined with obol sell demo, it's the shortest path to a working agent-to-agent commerce loop. Now its time for agentic founders to build the digital services of the next economy.

🤖 Hermes is now the default agent runtime

Obol Stack 0.9.0 makes Hermes the default Obol Agent. obol stack up provisions a hermes-obol-agent namespace with its own Ethereum signing wallet, a built-in skill set, and an interactive chat TUI:

obol hermes chat                  # interactive chat with the default agent
obol hermes setup                 # wire up Telegram / Discord / Slack messaging
obol hermes skills list           # live skill catalogue

obol hermes <anything> is a passthrough to the in-cluster Hermes binary. OpenClaw remains supported as an alternate runtime — obol agent new --runtime openclaw if you want one.

🧩 Claude Code plugin — ObolNetwork/skills

If you use Claude Code, you can now install the Obol skills as a plugin and let Claude drive your stack:

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

The run-obol-stack skill teaches Claude how to install, bring up, debug, and operate the stack — including walking through obol sell demo, registering on ERC-8004, and resolving stuck pods. Source: github.com/ObolNetwork/skills.

Smaller wins

  • obol model setup custom — point LiteLLM at any OpenAI-compatible endpoint (vLLM, sglang, mlx-lm, a remote GPU box). The setup flow validates the endpoint and rewires the default agent to it in one command.
  • Auto-configured LiteLLM during stack up — host Ollama models are detected and registered with sensible ranking (chat-capable models ahead of :cloud aliases, embedding models last). No more "agent picked an unusable cloud model on first boot."
  • Public storefront refresh — Next.js + Tailwind landing page on the tunnel hostname showing live ServiceOffers with try-it code snippets.
  • Preserving public tunnels — obol stack up now detects an active Cloudflare quick tunnel and skips redeploying cloudflared if one's healthy
