+*   🔐 [AgentTalk](https://github.com/douglasborthwick-crypto/agenttalk) by [@douglasborthwick-crypto](https://github.com/douglasborthwick-crypto) - Condition-gated session layer for agent-to-agent communication. Both agents verify their wallets satisfy the same on-chain conditions (token balances, NFT ownership, EAS attestations) across 33 blockchains before a session begins. ECDSA P-256 signed, ES256 JWT attestations verifiable offline via JWKS. Three API calls to a mutual session: declare conditions, join channel, verify. Discovery via `.well-known/agents.json`.

Evaluates wallets against conditions (token balances, NFT ownership, EAS attestations) across 33 blockchains and returns ECDSA-signed (ES256) JWTs verifiable offline via JWKS. Agents use it to prove on-chain holdings without exposing balances — signed boolean, not raw data.
