#### Cavos
Embedded wallet SDK that gives each user a classic `G…` account behind Google, Apple, GitHub, Telegram, or email sign-in, with reserves and fees sponsored.
- **Website**: https://cavos.xyz
- **Docs**: https://docs.cavos.xyz/docs/stellar ([llms.txt](https://docs.cavos.xyz/llms.txt))
- **GitHub**: https://github.com/cavos-labs/kit
- **Authorization model**: One Ed25519 spend key, derived by HKDF from a per-user MasterDEK and held in the browser as a non-extractable WebCrypto key (inside the Cavos vault iframe by default in the React provider with an `appId`). Stellar on React Native and Node is not on this path yet
- **Use Case**: In-app wallets for users who have no Stellar wallet
- **Features**:
- Classic `G…` account that also signs its own Soroban `require_auth` entries
- Sponsored account creation (`create()`), trustlines, and fee-bumps; the relayer cannot authorize the account's operations
- Optional restore by signing in again: an AWS Nitro enclave holds a sealed copy of the MasterDEK and re-encrypts it to a new device; the enclave does not sign and is part of the trust model
- Optional passkey that stores an encrypted copy of the MasterDEK
- Live on mainnet: [example account](https://stellar.expert/explorer/public/account/GCTAQXKRGWROJ5UZBLUQ472PNNFOPQQOJBPCVSVCM5SKPKDOAVP5LG4Q)

#### OpenZeppelin Relayer
Service for fee-sponsored transaction submission.
