I probably didn't express myself accurately. I meant LP for the new token, not the farm.
Have you been checking this
https://unicrypt.network/? In my opinion if unycript was cheap enough. it's only charging 0.3% as fees to lock your token. There are some like team.finance , deeplock and many more but i have not yet checked how much they charge for the fees. I think that the fees charged by unicrypto is still affordable for you. Unicrypto available for some blockchains include BSC. It's better if you check another LP vesting like team.finance.
for me unicrypt is the best one. Mostly of crypto developers were using unicrypt to lock their liquidity.
