Use cases

​

Mainnets

Use mainnets for production-grade transactions and interactions using CDP APIs:

• Sending real crypto funds (e.g., withdrawals, payments)
• Interacting with live DeFi protocols (such as staking)
• Reading onchain data for dashboards, analytics, etc.

CDP APIs can help simplify production workflows by letting you query balances, transactions, or fetch events without running a node.

​

Testnets

Use testnets for development, testing, or QA with no real funds involved:

• Testing smart contract deployments before mainnet launch
• Simulating workflows (like login, staking, etc.) with testnet funds
• Continuous Integration tests that run contract calls
• Demo purposes for sandbox environments

​

Layer 2s

Use Layer 2s, such as the Base network, for lower fees and faster transactions:

• Powering gas-efficient wallets or dapps
• Game or social app activity (frequent, low-cost interactions)
• Bridging assets between networks
