We’ve deeply integrated Privy to handle wallet creation, key management, and transaction delegation with a balance of security, automation, and decentralization. Here's how the system works across wallet types and automation scopes:
🧬 Embedded Wallets (Privy-Managed)
Upon signing in with any Authentication Provider (Google, Discord, Telegram, etc.), users are provisioned a non-custodial embedded wallet via Privy.
🔍 Technical Overview:
- Key Material: Private keys are securely encrypted and stored via Privy’s MPC + enclave-backed architecture.
- Ownership: You remain the sole controller; Privy handles secure key provisioning but never has access to raw private keys.
- Control: You can export and self-custody your wallet at any time.
🧠 Automation Capabilities Enabled:
- Instant Token Approvals & Swaps: Facilitated through delegated signing, enabling immediate execution without manual confirmations.
- Gas-Optimized Micro-Transactions: Perfectly suited for high-frequency interactions such as bump buys, ensuring minimal overhead and enhanced user experience.
- Automated Token Airdrops: Seamless bulk distribution of tokens to predefined recipient sets without manual intervention.
- Smart Wallet-Based Token Locking: Automated, secure management of vesting schedules and lockup mechanisms via embedded smart wallets.
- Server-Delegated Limit Orders & DCAs: Enabled through secure session signers, offering automated execution based on pre-set criteria.
🤖 Session Signers: Automated Execution Without Compromise
Privy’s Session Signer framework provides a powerful backend solution to securely delegate automated transaction execution from embedded wallets.
🔍 Technical Implementation:
- Ephemeral Session Keys: Session keys are generated client-side with scoped permissions and securely transmitted using cryptographic protocols (ECDSA) to the server.
- Transaction Delegation: These keys are scoped explicitly, allowing transaction signing strictly limited to predefined smart contracts and specified actions (token swaps, limit orders, DCAs).
