Custom delay (delay_ms)

By default, the Kolibrio auction on Solana uses a 50 ms delay. This is considered the optimal balance between latency, arbitrage discovery time, and transaction landing speed.

Every transaction is temporarily held during this window to search for profitable arbitrage opportunities:

• If no arbitrage is found, the transaction is released to the leader as a single standalone transaction.

• If an opportunity is found, the transaction is included in an atomic bundle together with the arbitrage leg.

For specific use cases, some users may prefer different behavior:

• Higher delay (e.g. 100 ms) — maximizes the probability of discovering and landing arbitrage atomically.

• Lower delay (e.g. 0 ms) — minimizes latency but significantly decreases the chances of landing arbitrage atomically.

Kolibrio supports this via a custom query parameter.

delay_ms=50
