Examples

Set the transaction deadline and query the current value.


    javascript
    
    
function main() {
    exchange.IO("deadline", 300)
    Log("Deadline:", exchange.IO("deadline"), "seconds")
}

TypeDescription

string

Fixed as deadline, which sets or queries the transaction deadline.

Remarks

If a swap transaction is not confirmed on-chain before the deadline, it is reverted when executed. This prevents a transaction that has been pending for a long time from being filled after a large price move.

The KyberSwap exchange object passes the deadline to KyberSwap when the swap transaction is built; transactions built by 1inch carry no deadline, so the setting has no effect on swaps of a OneInch exchange object.
