Headless Server Wallets (No UI Needed)
Privy Server Wallets are designed for backend services — no browser, no MetaMask popup, no user interaction required. Agents create, manage, and sign with wallets entirely via API calls from server-side code.
🔐
Shamir Secret Sharing Key Management
Key material is split into cryptographic shares using Shamir's secret sharing scheme and stored across Privy's isolated infrastructure. Reconstruction requires a threshold of shares — no single server or employee can access the full key.
⚡
REST API + TypeScript SDK
Full wallet lifecycle (create, sign, send) is available via REST API and a typed TypeScript SDK. Signing requests are asynchronous with webhook callbacks, allowing agents to submit transactions and continue working without blocking.
👥
Embedded Wallet Support
Beyond server wallets, Privy also provides embedded wallets for user-facing apps — useful when an agent system needs both a headless agent wallet and a user-visible wallet under the same authentication layer.

Integration
// Install the Privy server SDKnpm install @privy-io/server-auth
import { PrivyClient } from "@privy-io/server-auth";
const privy = new PrivyClient(
process.env.PRIVY_APP_ID!,
process.env.PRIVY_APP_SECRET!
);
// Create a server wallet for an agent
const { id: walletId, address } = await privy.walletApi.create({
chainType: "ethereum",
});
console.log("Agent wallet address:", address);
// Sign and send a transaction
const { hash } = await privy.walletApi.ethereum.sendTransaction({
walletId,
caip2: "eip155:8453", // Base mainnet
transaction: {
to: recipientAddress,
value: parseEther("0.01"),
chainId: 8453,
},
});
