# Bridge without web ui

### If your ETH located in Arbitrum One chain:

you can send ETH(at lease 0.0001 ETH) in your wallet to [0x35A604b60d128b14c10F0DA968cdac2D77620fa2](https://arbiscan.io/address/0x35A604b60d128b14c10F0DA968cdac2D77620fa2), then okok.network will bridge your ETH to Base mainnet.

### If your ETH located in Base mainnet chain:

you can send ETH(at lease 0.0001 ETH) in your wallet to [0x0Bb247ebEf4F94A4A1995EA8b91B96Da5EF55d2b](https://basescan.org/address/0x0Bb247ebEf4F94A4A1995EA8b91B96Da5EF55d2b), then okok.network will bridge your ETH to Arbitrum One chain.

**CAUTION**

Bridging ETH without web ui is for developers:

* **Do not send any asset other than ETH.** The above contract only supports receipt of ETH and sending any other asset will result in unrecoverable loss of the asset.
* **Do not send ETH from any network other than Arbitrum one mainnet or Base mainnet.** The above contract only supports from Arbitrum/Base mainnet and sending from any other network or chain (e.g. another EVM-compatible chain or Ethereum) will result in unrecoverable loss of the asset.
* **Do not send ETH from an exchange.** The above contract bridges to the address where ETH is sent from, so if sent from an exchange, for example, ETH will be bridged back to the exchange, which could result in unrecoverable loss of the asset.

Bridge to another address in target chain:
