This guide provides an overview of the networks supported by CDP APIs. Skip to the network identifiers section to view a high-level list, but keep in mind supported networks vary by CDP tool or feature, as detailed in this guide.
What is a network?
A network is the blockchain infrastructure supporting transactions, dapps, and smart contracts, with its own rules, consensus mechanism, and native tokens. For example, wallets, addresses, and assets are created on a specific network.
In addition to our SDK, we provide REST and JSON-RPC APIs for more granular management of your resources and onchain data. Individual API capabilities vary by network.
| Tooling | Functionality | Networks |
|---|---|---|
| AgentKit | AI wallet management | • Base by default • Configurable via wallet provider • See network identifiers |
| Base Appchains | Scalable, customizable blockchains | • Base |
| Faucets | Testnet token distribution | • Base by default • See Supported Assets |
| Node | Free RPC endpoints | • Base |
| Onchain Data | Easy access to historical data and webhooks for onchain events | • Base • Ethereum • Solana • Arbitrum • Polygon • See API Reference |
| Onramp | Fiat-to-crypto conversions | • Support for > 50 networks • See Onramp section |
| Paymaster | Gas sponsorship for your users | • Base |
| Reputation | Risk and behavior scoring | • Base • Ethereum • Bitcoin (risk only) |
| Staking API | Programmatic staking | • Ethereum • Solana • See API reference |
| Swap API | Swap tokens and trade | • Base • Ethereum |
| Verifications | Open-source, onchain verifications | • Base |
| Wallet API | Wallet management | • Base by default (gasless sends) • Configurable during creation or via external address • See network identifiers |
Use our Onramp API to interact with various networks and make it easier for you to move money seamlessly between fiat and onchain economies.

To fetch the most up-to-date list of supported countries and payment methods, use Onramp’s Config API endpoint. It returns a JSON object detailing Onramp-supported regions, along with available payment options for each location.
Mainnets vs. Testnets
| Testnet | Mainnet |
|---|---|
| Base-Sepolia | Base-Mainnet |
| Ethereum-Sepolia, Ethereum-Hoodi | Ethereum-Mainnet |
| Solana-Devnet | Solana-Mainnet |
Use mainnets for production-grade transactions and interactions using CDP APIs:
CDP APIs can help simplify production workflows by letting you query balances, transactions, or fetch events without running a node.
Use testnets for development, testing, or QA with no real funds involved:
Use Layer 2s, such as the Base network, for lower fees and faster transactions:
Both our REST APIs and JSON-RPC APIs serve distinct purposes are are optimized for different use cases:
You should use our REST APIs for working with structured data and predefined resources, and our JSON-RPC APIs for onchain data and operations where you need historical balances or the ability to perform batch requests.
