On-chain bytes are precious. In Rust, the bool type takes up a whole byte despite needing only one bit to be represented. ( See ) I wrote a proc macro that ergonomically gets/sets individual bits in a u8, allowing devs to pack up to 8 bools into one u8.

It turns out we can do better – asset transfer using ~1k CU. This is using a custom entrypoint (nitrate) based on @cavemanloverboy 's solana-nostd-entrypoint plus a few tweaks. The savings in compute are correlated with the number of accounts that the instruction receives – more
