Swap Fee & Blockhain

admin, i want to know about swap fee in trustwallet. Regarding the approval, where will the funds from the fee go if we swap in Poocoin or directly swap in trust? will the funds go to blockchain?
what is the founder of blockchain ( blockchain app wallet) (Blockhain Site) ?

a few years ago if we swap airdrop tokens / other tokens in trust we only got a coin fee that we have. not a BSC network coin fee, solana etc.
but now we have to have the network balance, why can that happen admin? thx 4 yur time
