# Bridging

## Bridge ETH to BERA Cross-Chain Swap

This use case bridges ETH from Ethereum to its native gas token equivalent, BERA, on Berachain.

[**Try this route →**](https://happypath.enso.build?chainId=1\&outChainId=80094\&tokenIn=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE\&tokenOut=0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE)

**Route mechanics**:

* Swap native ETH to USDC using 0x protocol on Ethereum mainnet
* Bridge USDC from Ethereum (chain 1) to FIXME (0x549943e04f40284185054145c6e4e9568c1d3241) on Berachain (chain 80094) using Stargate protocol
* Swap the bridged token to native BERA using ooga-booga protocol on Berachain

## Zap ETH from Ethereum to get sUSDe on Ethena

This use case gets exposure to delta-neutral yield from Ethena in a single transaction.

**Route mechanics**

* Swap native ETH to sUSDe using KyberSwap protocol in a single transaction

```mermaid theme={null}

    ETH((ETH)) --> A1[kyberswap.swap] --> sUSDe((sUSDe))
```

```ts theme={null}

const PLUME_CHAIN = 98866;
const ARBITRUM_CHAIN = 42161;

## Bridge ETH for styHoney

Convert `ETH` on Ethereum into a staked yield position (`styHONEY`) on Berachain.

```javascript theme={null}
import { Address, EnsoClient, RouteParams } from "@ensofinance/sdk";

const ETHEREUM_MAINNET = 1; // Ethereum Mainnet
const BERACHAIN_MAINNET = 80094;
const userAddress = "your-wallet-address" as Address;

const ETH_Ethereum = "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE" as Address; // ETH on Ethereum
const styHONEY = "0x99d6A0FB9420F3995fD07dCc36AC827a8E146cf9" as Address;

const routeParams: RouteParams = {
 fromAddress: userAddress,
 receiver: userAddress,
 chainId: ETHEREUM_MAINNET, // Start from Ethereum
 destinationChainId: BERACHAIN_MAINNET,
 amountIn: ["200000000000000000"], // 0.2 ETH
 tokenIn: [ETH_Ethereum],
 tokenOut: [styHONEY],
 routingStrategy: "delegate",
 slippage: "400", // 4% slippage for complex cross-chain
 referralCode: "eth-styhoney",
};

const route = await client.getRouteData(routeParams);
await sendSmartWallet(route.tx, route.gas);
```

**Route Mechanics:**

* Swap `ETH` to `USDC` on Ethereum Mainnet.
* Bridge `USDC` to `USDCe` on Berachain via Stargate.
* Swap `USDCe` to `HONEY` on Berachain.
* Deposit `HONEY` into Bearn `yHONEY` vault.
* Stake `yHONEY` to receive `styHONEY`.
