Which blockchain networks does trip1 support for USDC payments?

In short

• trip1 accepts USDC on five networks: Ethereum, Polygon, Arbitrum, Optimism, and Base.
• Polygon, Arbitrum, Base, and Optimism are Layer 2 networks with the lowest fees (typically under 10 cents) and fastest confirmation.
• Ethereum mainnet works but tends to be more expensive during busy network periods.

The five supported networks

• Ethereum - the original USDC home network. Higher gas fees, especially during congestion.
• Polygon - Layer 2 with very low fees, often the cheapest option for USDC payments.
• Arbitrum - Layer 2 rollup with fast finality and low fees, well-supported across major wallets.
• Optimism - another Layer 2 rollup with quick confirmation and modest fees.
• Base - Coinbase's Layer 2, easy to fund directly from a Coinbase account.

How to choose the right network

Pick the network where you already hold USDC. If you hold USDC on Polygon, send from Polygon. If you hold it on Arbitrum, send from Arbitrum. Bridging between networks adds time and a small fee.

If you have USDC on multiple networks, the Layer 2 options (Polygon, Arbitrum, Base, Optimism) almost always cost less and confirm faster than Ethereum mainnet.

What happens if you pick the wrong network

Important: always match the network shown at trip1 checkout. USDC sent on the wrong network can be lost and trip1 cannot recover those funds. Double-check the network selection in your wallet before sending.
