I want to create a smart contract where I can pair my token with another token, the first deposit be permanent forever, so it can not be withdrawn never, and after that anyone making deposits and earning from it be paid with whichever token I placed,

For example I paid balancer token with uniswap token, and I want to add some

Extra liquidity so I decide to add CVC as extra

So the contract will hold the CVC and use it to pay anyone who deposits liquidity into the smart contract

When the CVC is gone, when its all paid to the liquidity providers, then the smart contract can pay using the native tokens in that contract, and I want one ETHMNY token to be required to be place inside the contract

So the contract is cheaper to be produce, and we also need to force the liquidity for more than 6 Months in order to pay.
