What we're building, in order.
cash fetch <url> — detect 402 Payment Required, auto-swap BTC to USDC, sign via ECDSA, retry with proof. Supports Polygon, Arbitrum, Ethereum via Thirdweb facilitators.
Tool-use integration for Claude Code and Claude Desktop. Your agent calls wallet functions directly as MCP tools.
Pay x402 APIs directly with sats — Lightning, Arkade, or on-chain. No stablecoin swap needed. BIP-322 signed proofs, native Bitcoin settlement.
Per-agent limits, allowlists, time-based rules. Control how much an agent can spend and where, enforced at the enclave level.
Slack, Google, 1Password, YubiKey, Passkeys. Same enclave identity, any auth method your agent environment supports.
Replace in-memory store with PostgreSQL. Durable state across restarts for production deployments.
Get notified when transactions complete, swaps settle, or balances change. Push events to your agent's event loop.
