Bridging times
For v1, transferring funds between blockchains requires finality on the source chain.
Below are typical bridging times for each source chain.
CCTP
Mainnet
| Source Chain | Domain | Number of blocks | Average time |
|---|---|---|---|
| Ethereum | 0 | 65 | 13 minutes |
| Avalanche | 1 | 1 | 20 seconds |
| Optimism | 2 | 65 ETH Blocks | 13 minutes |
| Arbitrum | 3 | 65 ETH Blocks | 13 minutes |
| Noble | 4 | 1 | 20 seconds |
| Base | 6 | 65 ETH Blocks | 13 minutes |
| Polygon | 7 | 200 | 8 minutes |
Testnet
| Source Chain | Domain | Number of blocks | Average time |
|---|---|---|---|
| Ethereum Goerli | 0 | 5 | 1 minute |
| Avalanche Fuji | 1 | 1 | 20 seconds |
| OP Goerli | 2 | 5 | 20 seconds |
| Arbitrum Goerli | 3 | 5 | 20 seconds |
| Noble Testnet | 4 | 1 | 20 seconds |
| Base Goerli | 6 | 5 | 20 seconds |
| Polygon PoS Mumbai | 7 | 1 | 20 seconds |
IBC
IBC transfers typically take 13 seconds. The timing of an IBC transfer depends on relayers and the network conditions of both chains.
