Layer 2 transfer guide
Base vs Arbitrum transfer
Base and Arbitrum can both reduce transfer costs compared with Ethereum mainnet. The safer choice depends on the asset, the sending exchange, and whether the receiving platform supports that exact network.
| Network | Useful when | Check first |
|---|---|---|
| Base | You are moving USDC or supported assets to Base-compatible platforms | Whether the exchange supports Base deposit for that asset |
| Arbitrum | You use Arbitrum DeFi, bridges, or exchanges with Arbitrum support | Whether the token contract and network match the receiving page |
Fast answer
Use the network that both sides clearly support. A lower fee is not worth it if the receiving exchange treats the deposit as unsupported.
Base vs Arbitrum at a glance
| Decision point | Base | Arbitrum |
|---|---|---|
| Common use case | USDC routes and Base-native apps | Arbitrum DeFi, bridges, and supported exchange routes |
| Primary risk | The destination does not accept the asset on Base | The destination accepts Arbitrum for another token, but not your token |
| Best next check | Receiving deposit page lists Base for the same asset | Receiving deposit page lists Arbitrum for the same asset |
When to choose each
Base is a strong default for USDC routes when both sides support it. Arbitrum is useful when your destination is already in the Arbitrum ecosystem or the exchange clearly lists Arbitrum deposits for the same asset.
Pre-transfer checklist
- Confirm the asset ticker and network name on the receiving deposit page.
- Check whether the sending platform uses a different label for the same network.
- Compare the withdrawal fee against your transfer amount, not only against another network.
- Use a small test transfer when you have not used that Base or Arbitrum route before.
Before sending, run the fee ratio calculator and review the wrong-network checklist.
