Agent-Grade Self-Custody OS
Wallet + signing stack whose primary user is an AI agent — passkey-native, policy-bound, MCP-first.

Score 27/30. Default custody surface for the next 100M BTC users and every money-touching AI agent. Never-see-a-seed-phrase UX moat + true self-custody regulatory moat. Requires miniscript + MuSig2 + TEE + MCP fluency. Architecture: agent key in 2-of-2 with programmatic TEE co-signer (AWS Nitro) + human recovery after timelock. Products: passkey-rooted wallet, MCP server with scoped capabilities ("spend 50K sats/day to whitelisted endpoints"), agent-policy DSL. Kill: a dominant wallet (Phoenix, Zeus) ships a good-enough agent API; a high-profile agent-drain.
