ACCOUNTV3_ADD_LIQUIDITY

Opcode : 0x3ebe5431

This operation adds liquidity and a minting request to the account. This contract is used as a barrier to collect together data about the proofs of funding two tokens and the request to mint some liquidity. Common usage is as follows - send one jetton with the mint instructions and the second jetton with the mint instructions. And as soon as they will both arrive AccountV3 would trigger the minting request in the pool. This makes minting independent of the order in which jettons arrive. Account refers to jettons in the pool (account::pool_address) order Access Rights: This operation is allowed for account::pool_address
