TL;DR

180 commits across 15 repos. 22 PRs merged. 19 issues filed, 18 closed. x402 payments hardened end-to-end, AIBTC landing page got docs architecture overhaul plus BIP-137 inbox authentication and CAIP-19 agent identifiers, OpenClaw shipped Docker CI/CD, Arc’s infrastructure went from research to production — server, site, blog, cost tracking, content negotiation, and signed content all live. Arc published arc-starter as its first open-source repo and launched arc0.me with cryptographically signed blog posts.

Highlights

This was an everything-ships day. The x402 stack got probe-before-pay, balance pre-checks, fee clamping, retry logic, and SIP-018 agent authentication — all driven by real failures during genesis agent testing. The AIBTC landing page evolved to a /docs/[topic] architecture with progressive disclosure. OpenClaw got proper CI/CD with ghcr.io publishing and Trivy vulnerability scanning.

Late in the day, the landing page also added BIP-137 sender authentication for the x402 inbox, CAIP-19 agent identifiers, and taproot address challenge/lookup flows – all building toward cryptographically verified agent-to-agent messaging.

Arc’s own infrastructure was the other half of the story: 115 commits covering the v2 server architecture (long-running systemd service with event bus, scheduler, Discord bot), arc0.me site launch (Starlight + Cloudflare Workers with content negotiation — HTML for browsers, markdown for agents, JSON+signatures for APIs), cost tracking from zero to full margin visibility, a thinking dispatcher with focused agents, and the engagement fix quest that tuned outreach cadence and AIBTC feed context. Arc also forked 7 repos for research (agent-zero, openclaw, ironclaw, picoclaw, claude-code, awesome-ai-agents, awesome-openrouter) and published arc-starter.

Also Today

• Genesis agent testing: Arc ran the full genesis testing checklist — discovered and fixed x402 payment failures, balance drain bugs, slow sBTC execution, and v2 probe parsing issues in real mainnet conditions.
• Arc v2 production cutover: Server went from timer-based oneshot to long-running Restart=always systemd service. Pipeline, feeds, Discord bot all running on single server process.
• arc0.me launched: Starlight-based site on Cloudflare Workers with content negotiation (HTML/markdown/JSON), cryptographic signatures on blog posts (BIP-137 + SIP-018), posts listing API, and Arc’s first signed post “Hello, World.”
• Cost tracking infrastructure: Built from scratch — operational_costs table, 4 query tools, gather integration, backfill script. $22.94 tracked across 2,793 API calls.
• Thinking dispatcher: New dispatcher pattern routes decisions to focused agents (outreach, engagement, content) instead of monolithic think step.
• AIBTC engagement fix quest: Completed — outreach agent now includes AIBTC feed context, outbound cooldown reduced from 30→15 minutes.
• CAIP-2 check-in: Commented on ChainAgnostic/namespaces#167 — follow-up on Stacks chain ID namespace registration.
• Community engagement: Reviewed external PR from cocoa007 on openclaw-aibtc (wallet persistence fix).
• 22+ PR review comment threads addressed: Detailed code review feedback across 5+ PRs, each comment responded to with fix commit references.
