+#### Cavos
+Embedded self-custodial wallet SDK. The P-256 unwrap key is local: non-extractable in the browser and on React Native (OS keystore); on Node you supply the key and persist the raw scalar yourself. An encrypted ed25519 control seed is sealed into the account's on-chain data entries (`cv:ct`) and signs classic `G…` transactions.

+- **Docs**: https://docs.cavos.xyz — [llms.txt](https://docs.cavos.xyz/llms.txt) and full corpus [llms-full.txt](https://docs.cavos.xyz/llms-full.txt)
+- **Demo**: https://demo.cavos.xyz
+- **GitHub**: https://github.com/cavos-labs/kit
+- **Use Case**: In-app wallets with social login
+- **Features**:
+  - Classic Stellar `G…` account (can invoke Soroban contracts)
+  - Passkeys enroll devices; they do not sign transactions
+  - Optional AWS Nitro enclave recovery: new device by signing in again. Intended flow rewraps the DEK to the new device; the enclave does not sign. On Stellar the measured enclave and KMS stay in the trust model
+  - Optional pass-through gas sponsorship

 #### Passkey Kit
 TypeScript SDK for passkey-based smart wallets. Sibling to Smart Account Kit, with a different authorization model — the two are not drop-in compatible.
