When you deploy a collection with Mantial, we also deploy a payment splitter on the Ethereum blockchain. This means that we can't touch your money and no partner can touch each other's money either.
But... with freedom comes responsibility. If you lose access to your wallet, there's no way for us nor for anyone else to recover your money.
Yes, Mantial is entitled to receive a percentage from your primary sales and a percentage for the level of royalties that you decide.
