Start with the network and asset
Bridge time depends on the source chain, destination chain, route design, required confirmations, liquidity and provider processing. There is no universal bridge time for every asset and network pair.

What determines cross-chain transfer time and why bridge estimates can change.
Bridge time depends on the source chain, destination chain, route design, required confirmations, liquidity and provider processing. There is no universal bridge time for every asset and network pair.
Fast routes can complete quickly when networks are healthy and liquidity is available. Congestion, slow confirmations, provider delays, or additional swap steps can increase the total time.
Treat an estimated time as a live estimate rather than a promise. The blockchain transaction status is the best way to tell whether the source transaction has been accepted.
If a transfer is pending, avoid submitting a duplicate transaction. Check the transaction hash, route status and destination network before taking further action.
