Hello, Recently my friends and I are building a video game marketplace that only accepts Bitcoin, everything is ready besides a main Bitcoin wallet system. the original has API impalanted which needs to be removed. it must be like escrow or multi sig, a customer only releases funds once product is received (he clicks finish). our deadline is set max for 5-10 days, you are allowed to use premade directories (GitHub) and we wish to take fees from the withdrawals from users wallets. this system must be stable , no API! No marketplace fees.
