Does anybody know how to detect mayhem tokens on pumpfun with the logsubscribe method. When a new coin is created you can see it in the logs and then theres a discriminator with some data to decode. But I can't seem to find the mayhem bool byte. Because when you try to snipe a coin and then you have to fetch the bondingcurve data with getaccountinfo you miss a lot of time.

The BondingCurve account contains a field, is_mayhem_mode which is a bool if set to true means that they have it enabled ref: https://github.com/pump-fun/pump-public-docs/blob/9d874ec2763ac60f510d2bba80c5126c1fe133a8/idl/pump.json#L6002-L6005 use anchor_lang::AccountDeserialize; #[derive(AccountDeserialize)] pub struct BondingCurve { pub virtual_token_reserves: u64, pub virtual_sol_reserves: u64, pub real_token_reserves: u64, pub real_sol_reserves: u64, pub token_total_supply: u64, pub complete: bool, pub creator: Pubkey, pub is_mayhem_mode: bool, pub is_cashback_coin: bool, } let mut data: &[u8] = &account.data; let bc = BondingCurve::try_deserialize(&mut data)?; let is_mayhem = bc.is_mayhem_mode;
