Privacy-Enhanced API Gateway
Frequently Asked Questions
Get clear answers on our development process, security, and support for your privacy-focused blockchain infrastructure.
A privacy-enhanced API gateway is a specialized middleware layer that sits between your blockchain application and its users or services. It provides secure, authenticated, and rate-limited access to your on-chain data and smart contract functions while implementing privacy-preserving techniques. You need one to protect sensitive transaction data, manage API keys securely, prevent front-running, and comply with data privacy regulations like GDPR, without sacrificing the transparency of the underlying blockchain.
