Lookup Tables

Lookup tables reduce your transaction size. We provide pre-initialized lookup tables that cover the Light's program IDs and accounts:

Lookup Table #1 (Mainnet)	9NYFyEqPkyXUhkerbGHXUXkvb4qpzeEdHuGpgbgpH1NJ
Lookup Table #1 (Devnet)	qAJZMgnQJ8G6vA3WRcjD9Jan1wtKkaCFWLWskxJrR5V

We provide a helper function here if you need to extend a custom lookup table.
