Brass Band was created on pump.fun. In the same transaction its creator fees were split 30% to a streamer vault, 60% to the launcher's wallet and 10% to the protocol, and the split admin was revoked.

The derivation is real math. Only the program id is a placeholder until the vault program is deployed, so this vault does not exist on-chain yet.
