Check cross-chain bridge status

Check cross-chain bridge status

get

Check the status of a cross-chain bridge transaction started via the trading execute endpoint.

Pass the source-chain transaction hash from the execute response, plus the source and destination chains of the swap.

Aggregator: pass the aggregator field from the quote you executed. Status checks default to lifi, and Relay transactions are not found under that default — always set aggregator=relay for Relay bridges.
