+# L2
+
+Modules exposes Lido MultiChain deployments. [See full info here](https://lido.fi/lido-multichain).
+
+## LidoSDKL2
+
+This is core module for all L2 functionality. It will throw error if used on with chains that are not currently supported.
+
+| **Chain**        | **wsETH** | **stETH+(un)Wrap** |
+| ---------------- | --------- | ------------------ |
+| Optimism Sepolia | ✅        | ✅                 |
+| Optmism          | ✅        | ✅                 |
+| 🔜               |           |                    |
+
+Use this helper to understand which contracts are supported on chain:
+
+```ts
+import {
+  LidoSDKL2,
+  LIDO_L2_CONTRACT_NAMES,
+  CHAINS,
+} from '@lidofinance/lido-ethereum-sdk';
+
+LidoSDKL2.isContractAvailableOn(
+  LIDO_L2_CONTRACT_NAMES.wsteth,
+  CHAINS.OptimismSepolia,
+); // true
+// Example
+LidoSDKL2.isContractAvailableOn(LIDO_L2_CONTRACT_NAMES.steth, CHAINS.Arbitrum); // false
+```
+
+### Fields
+
+- `wsteth`: see [LidoSDKL2Wsteth](#lidosdkl2wsteth)
+- `steth`: see [LidoSDKL2Steth](#lidosdkl2steth)
+
+### Methods
+
+On L2 with stETH deployments bridged wstETH is wrapped to stETH. And stETH is unwrapped to wstETH. Those semantics are upkept in SDK with more explicit naming. See [LIP-22](https://github.com/lidofinance/lido-improvement-proposals/blob/develop/LIPS/lip-22.md#rebasable-token-steth-on-l2) for more details.
+
+#### Wrap bridged wstETH to stETH
+
+To wrap stETH you first need to approve stETH to wrap contract:
+
+```ts
+import { LidoSDK } from '@lidofinance/lido-ethereum-sdk';
+
+const lidoSDK = new LidoSDK({
+  rpcUrls: ['https://rpc-url'],
+  chainId: 11155420, // OP sepolia
+  web3Provider: LidoSDKCore.createWeb3Provider(11155420, window.ethereum),
+});
+
+// get existing allowance
+const allowance = await lidoSDK.l2.getWstethForWrapAllowance();
+
+// if value is more than allowance perform approve
+if (allowance < value) {
+  const approveResult = await lidoSDK.wrap.approveWstethForWrap({
+    value,
+    callback,
+  });
+}
+
+// wrap wstETH
+const wrapTx = await lidoSDK.wrap.wrapWstethToSteth({ value, callback });
+
+const { stethReceived, wstethWrapped } = wrapTx.results;
+```
+
+#### Unwrap stETH to wstETH
+
+```ts
+// unwrap stETH to receive wstETH
+const unwrapTx = await lidoSDK.l2.unwrapStethToWsteth({
+  value: unwrapAmount,
+  callback,
+});
+
+console.log(unwrapTx.result.stethUnwrapped, unwrapTx.result.wstethReceived);
+```
+
+### Wrap utilities
+
+For all transaction methods helper methods are available similar to `stake` module:
+
+- `...populateTX`: returns ready to sign transaction object with all data encoded
+- `...simulateTX`: performs dry-ran of the transaction to see if it will execute on the network
+
+## LidoSDKL2Wsteth
+
+This submodule is built on top of existing ERC20 modules and has extra functionality. See docs for all [ERC20 related methods](./w-steth.md).
+For original L2 ABI functionality use `.getL2Contract()` and get raw Viem contract instance.

+  amount,
+  to,
+});
+
+// converting stETH amount to shares trough on-chain call based on actual share rate
