Public keys are meant to be used from any front-end integration like the vesicash widget, escrow pay link, escrow pay buttons and in our Mobile SDKs only. By design, public keys cannot modify any part of you or your customer account details besides initiating transactions and making payments. The private keys however, are to be kept secret. If for any reason you believe your private key has been compromised or you wish to reset them, you can do so from the dashboard.
