v2026.2.15

v2026.2.15 promotes the 2026.2.15 release train to stable, with stronger chain safety, cleaner buyer/seller UX, and tightened skill/runtime guidance.

Highlights

• Added centralized chain parsing/validation helpers and enforced supported networks (Base mainnet + Base Sepolia) across server boot, leak launch, and leak config.
• Improved promo UX:
  • Network now displays as chain name + CAIP-2 ID.
  • Sale end renders in the viewer’s local time.
  • OG copy is shorter and clearer.
• Improved agent/buyer guidance:
  • Fast-path instructions are now present across promo/download/discovery surfaces.
  • Skill docs now emphasize execution-first flow and clearer funding guidance from 402 Payment Required.
• Strengthened publishing and key-handling posture from the beta cycle:
  • Seller publish safety gates.
  • Secure buyer key input modes and safer defaults.
• Updated release docs with explicit Clawhub prerelease publish instructions.

Breaking / Behavior Changes

• --buyer-private-key is no longer supported.
  • Use --buyer-private-key-file (default) or --buyer-private-key-stdin.
• Invalid or unsupported CHAIN_ID/--network now hard-fails instead of proceeding.

Upgrade Notes

• If you script buys, migrate any raw-key argument usage to file/stdin-based key input.
• Ensure your configured chain is one of:
  • eip155:8453 (Base)
  • eip155:84532 (Base Sepolia)
• If using the leak skill, runtime requirements now explicitly include both node and leak.
