+
+A user & developer friendly modular smart account implementation on ZKsync;
+simplifying user authentication, session management, and transaction processing.
+
+## Features and Goals
+
+<!-- prettier-ignore -->
+> [!CAUTION]
+> ZKsync SSO is under active development and is not yet feature
+> complete. Use it to improve your development applications and tooling. Please
+> do not use it in production environments.
+
+- 🧩 Modular smart accounts based on
+  [ERC-7579](https://eips.ethereum.org/EIPS/eip-7579#modules)
+- 🔑 Passkey authentication (no seed phrases)
+- ⏰ Sessions w/ easy configuration and management
+- 💰 Integrated paymaster support
+- ❤️‍🩹 Account recovery _(Coming Soon)_
+- 💻 Simple SDKs : JavaScript, iOS/Android _(Coming Soon)_
+- 🤝 Open-source authentication server
+- 🎓 Examples to get started quickly
+
+## Getting started
+
+Install the ZKsync SSO SDK package:
+
+```sh
+npm i zksync-sso
+```
+
+Add ZKsync SSO connector to your app (using `wagmi`):
+
+```ts
+import { zksyncSepoliaTestnet } from "viem/chains";
+import { createConfig, connect } from "@wagmi/core";
+import { zksyncSsoConnector } from "zksync-sso/connector";
+
+const ssoConnector = zksyncSsoConnector({
+  // Optional session configuration,
+  // if omitted user will have to sign every transaction via Auth Server
+  session: {
+    // Allow up to 0.1 ETH to be spend in gas fees
+    feeLimit: parseEther("0.1"),
+
+    transfers: [
+      // Allow ETH transfers of up to 0.1 ETH to specific address
+      {
+        to: "0x188bd99cd7D4d78d4E605Aeea12C17B32CC3135A",
+        valueLimit: parseEther("0.1"),
+      },
+
+      // Allow ETH transfers to specific address with a limit of 0.1 ETH per hour
+      // until the session expires
+      {
+        to: "0x188bd99cd7D4d78d4E605Aeea12C17B32CC3135A",
+        valueLimit: {
+            limit: parseEther("0.1"),
+            period: BigInt(60 * 60), // 1 hour in seconds
+        },
+      },
+    ],
+
+    // Allow calling specific smart contracts (e.g. ERC20 transfer):
+    contractCalls: [
+      {
+        address: "0xa1cf087DB965Ab02Fb3CFaCe1f5c63935815f044",
+        function: "transfer(address,uint256)",
+
+        // Optional call constraints (unconstrained otherwise):
+        constraints: [
+
+          // Only allow transfers to this address
+          {
+            index: 0,
+            condition: "Equal",
+            refValue: pad("0x6cC8cf7f6b488C58AA909B77E6e65c631c204784"),
+          },
+
+          // Transfer up to 0.2 tokens
+          {
+            index: 1,
+            limit: parseUnits("0.2", TOKEN.decimals), // Unlimited if omitted
+          },
+        ],
+      },
+    ],
+  },
+});
+
+const wagmiConfig = createConfig({
+   connectors: [ssoConnector],
+   ..., // your wagmi config https://wagmi.sh/core/api/createConfig
+});
+
+const connectWithSSO = () => {
+   connect(wagmiConfig, {
+      connector: ssoConnector,
+      chainId: zksyncSepoliaTestnet.id, // or another chain id that has SSO support
+   });
+};
