The bank holds the private keys on your behalf, as part of our custodial service. This is by design – it relieves you of the burden of key management and leverages our security framework. It’s similar to how we hold fiat: you don’t personally shuffle cash in a vault; we maintain it electronically for you. Likewise, with crypto, we keep the keys in secure custody. When you want to send crypto out or receive crypto in, those transactions are executed through our systems at your instruction. Some very technically-inclined clients ask if we support external wallet connectivity – at this time, we do not provide something like a MetaMask integration; all movements go through our secure portal. The upside is you benefit from insured custody and risk mitigation. If, for any reason, there were a security breach on the bank’s side (which we have never had), the bank is responsible for the loss, not you – unlike personal crypto wallets where if you lose a key, it’s gone forever. So, entrusting the private keys to us is part of the service that we offer to safeguard your digital assets.
