AgentaOS vs Privy
Privy embeds wallets into consumer apps. AgentaOS gives AI agents their own sovereign accounts. Different tools for different problems. Privy is designed for consumer apps where users need wallets without MetaMask. AgentaOS is designed for autonomous agents and bots that need to transact under enforceable guardrails without exposing a private key.Quick Comparison
| AgentaOS | Privy | |
|---|---|---|
| Primary use case | AI agent signing, developer key management | Consumer app embedded wallets |
| Key model | 2-of-3 threshold ECDSA (no single key) | Server-side key management, TEE enclaves |
| Custody | No single party holds the full key. You control your shares. | Privy holds keys on your behalf. |
| Pricing | Free and open source | Free tier + usage-based pricing |
| Source code | Open source | Proprietary |
| Agent support | Native SDK, CLI, MCP server | Not designed for agents |
| User authentication | Passkey (WebAuthn) + email | Email, social login, wallets, phone |

| Deployment | Managed platform + open source SDK | Privy-hosted only |
| Chain support | Every EVM chain | EVM + Solana |
When to Choose Agenta
- You’re building AI agents. AgentaOS is purpose-built for autonomous signing. SDK, CLI, and MCP server for agent integration.
- You want sovereign accounts. No single party holds the full key. The private key never exists.
- You need transaction guardrails. Spending limits, rate limits, contract allowlists, time windows. All enforced before every signature.
- You want the key to never exist. AgentaOS uses threshold signing. The private key is never assembled. Privy stores keys in secure enclaves, but the key does exist as a whole value.
When to Choose Privy
- You’re building a consumer app. Privy excels at onboarding non-crypto users. Social login, email login, phone login. No MetaMask required.
- You need social login. Google, Twitter, Discord, Apple. Privy supports them all.
- You don’t want to think about infrastructure. Privy is fully managed. So is AgentaOS — but Privy has a wider social login integration.
- User wallets, not agent accounts. Privy creates wallets per user. AgentaOS creates accounts per agent.
Key Architecture Difference
Privy: Stores the actual private key in a secure enclave (TEE). The key exists as a whole value inside the enclave. Privy manages the infrastructure. You trust their security. Agenta: The private key never exists as a whole value. Three shares are created via distributed key generation. Any two shares can co-sign, but no single share is useful alone. You host everything. This is not a philosophical difference. It changes the threat model:| Scenario | Privy | Agenta |
|---|---|---|
| Vendor gets hacked | Attacker may access keys | No keys to access. Attacker gets one share. |
| Your server gets hacked | N/A (Privy-hosted) | Attacker gets one share. Cannot sign alone. |
| Vendor goes down | Your users lose wallet access | Your agents keep signing (2 of 3 shares still work) |
| Vendor changes pricing | You’re locked in | Open source SDK. No lock-in. |
