The Sovereignty Matrix
Choosing a wallet infrastructure is a decision about trust. Cavos is the only **verifiable, MPC-free** infrastructure built natively for Starknet.
| Vector | Cavos | Privy / Dynamic | Passkey Wallets |
|---|---|---|---|
| Core Architecture | On-chain RSA-2048 Verification | MPC Shards (Off-chain) | Session Key Controllers |
| Signing Logic | Truly Verifiable On-chain | Provider-managed Shards | Browser-based Auth Hooks |
| AI Agent Signer | Native Headless / Master-less support | Requires key injection | Primarily human-centric |
| Mobile Experience | Native React Native SDK (Passkeys) | Browser / WebView dependent | Web app wrapper |
| Gasless / Sponsorship | Native AVNU Paymaster integration | Custom relayer setup | Integrated paymaster |
| Account Recovery | OAuth Identity (Google/Apple) | Shard-based recovery | Passkey / Social recovery |
| Implementation | npx skills add → ~15 min setup | Dashboard + API config | Contract-level integration |
| Sovereignty Mode | 100% Non-Custodial (No shards stored) | Provider-held key fragments | Self-custodial controller |
| Production Usage | 10+ dApps • 81+ wallets (growing) | Strong cross-chain adoption | Dominant in Starknet gaming |
| Performance | Direct L2 settlement | Bridge / backend latency | Optimized L2 settlement |

Why Cavos Wins
Verifiable Sovereignty
Traditional embedded wallets rely on MPC "black boxes"—centralized clusters holding fragments of your keys. Cavos is the only infrastructure that performs **RSA-2048 verification directly on-chain** in Cairo. Your identity is validated by the protocol, not a provider.
Zero-Trust AI Signers
AI agents need signers that can operate autonomously without exposing long-lived private keys. Cavos session tokens are authorized for specific contracts and spending limits on-chain, making it the standard for the next generation of autonomous Starknet apps.
Protocol-Native DX
While others build cross-chain abstractions that add latency, Cavos is 100% Starknet-native. From integrated AVNU paymasters to sub-account naming via named wallets, every feature is optimized for the Starknet native AA ecosystem.
Invisible UX, Total Control
Get your users into your app in under 30 seconds. No browser popups, no seed phrases, no extensions. Just a seamless Web2 login that results in a fully self-custodial Starknet account that works across every device.

Zero Shard Policy
Unlike MPC providers, we never store fragments of your key. RSA verification happens directly in Cairo. No off-chain cluster involved.
Master-less Agents
Authorized sessions allow AI agents to operate autonomously with on-chain guardrails. Perfect for Eliza-based frameworks.
Gasless Onboarding
Fully integrated with AVNU Paymaster to ensure your users never hit an "Insufficient Gas" error. Seamless from day zero.
