-The Gateway program derive a PDA (Program Derived Address) with seeds `b"meta"` and canonical bump.  This PDA account/address actually holds the SOL balance of the Gateway program.  For SPL tokens, the program stores the SPL token in PDA derived ATAs. For each SPL token (different mint account), the program creates ATA from PDA and the Mint (standard way of deriving ATA in Solana SPL program).
