Fees
CCTP
Users pay the gas cost (in USDC) to mint on the destination chain. These mints are triggered automatically by our relayer network.
The gas cost to mint can change based on L1 token prices and network congestion. These changes are reflected in the UI and will be updated here.
| Destination Chain | Fee ($) |
|---|---|
| Ethereum | 20 |
| Avalanche | 1 |
| Optimism | 1 |
| Arbitrum | 1 |
| Noble | 1 |
| Base | 1 |
| Polygon | 1 |
If you are a chain or app looking to subsidize bridging to your chain, reach out to us on Twitter (opens in a new tab).
