# Silver Card Sdk

The Zebec Card SDK allows developers to integrate the functionality of purchasing and managing Zebec virtual cards into their applications. We currently support EVM chains (Ethereum, Binance Smart Chain (BSC), and Base) and Bittensor Network with the flexibility to toggle between mainnet and testnet environments based on configuration.
