Cobo employs the ECDSA algorithm for signature verification. We strongly recommend that you generate your public and private API keys locally to ensure that Cobo neither has access to nor stores your private keys. After generating your keys locally, you can manage the public keys by heading to Cobo Custody Web-Wallet-API. For more information on private key generation, signing and verification, please refer to https://github.com/CoboGlobal/. For API references, please go to /api-references/overview/authentication.
