<table><thead><tr><th width="698">Sub Project:</th></tr></thead><tbody><tr><td>bridge ETH/USDC between Arbitrum and other chains(for example, Base, Blast, zkSync era, Scroll, ZKFair etc)</td></tr><tr><td>buy native gas token(BNB, MNT etc) with ETH in Arbitrum, we will send native token to your wallet address in target chain</td></tr></tbody></table>

### Low fee:

use Base official bridge: bridge fund from Ethereum to Base cost about **0.0020**357 ETH gas fee, for example [this](https://etherscan.io/tx/0x4b60892cb36c065de7c804ab4a52a48c683ea8a136281046bf4a4c0eb919c7d1)

use OKOK Network bridge: bridge fund from Arbitrum to Base cost 0.00006222 ETH([arbitrum fee](https://arbiscan.io/tx/0x78f254b2949618da5803a39f7bd3056912128138f2642feb7963c458aee3d2f0)) + 0.00006716 ETH([base fee](https://basescan.org/tx/0x84325629fbd27db306660573ce2034ab90f4fffdd0eb235ef3211b992c04ac0c)) = **0.0001**2938 ETH(total gas fee)

0.0020357 ETH / 0.00012938 ETH = **15.73**

**Conclusion**: use Base official Ethereum bridge cost much more than OKOK Network's.

### Fast speed:

Using OKOK Network to bridge ETH between Arbitrum and Base, funds can reach target chain within 20 seconds. Same response time as Base official proxy bridge if Ethereum not congested. But Ethereum is often congested, so good luck.&#x20;

### High safety:

OKOK Network uses the proven Intel SGX-based cross-chain bridge solution. Avalanche Bridge uses the same approach. The Intel SGX-based cross-chain bridge solution has extremely high security among many cross-chain solutions.
