Supported Networks

This page provides an overview of the blockchain networks we currently support.

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.

Payments APIs Network Support

By product

Payment API features vary depending on whether you’re using Coinbase Business or Coinbase Prime.

Feature	Coinbase Business	Coinbase Prime
Accounts API
Deposit Destinations API
Payment Methods API	-
Transfers API
Webhooks API

Accounts: In Production, Coinbase Business and Coinbase Prime both support creating accounts via CDP Portal, not APIs. The Accounts API is for listing and viewing account details.

Payment Methods: Currently only available for Coinbase Prime accounts linked to CDP. Payment methods allow you to transfer funds to external bank accounts via Fedwire (domestic USD) or SWIFT (international).

By asset and network

Use the Network identifier when specifying a network in API requests.

Network	Network identifier	Coinbase Business	Coinbase Prime
Aptos	aptos	USDC	-
Arbitrum	arbitrum	-	USDC
Base	base	USDC	USDC
Ethereum	ethereum	USDC	USDC
Optimism	optimism	USDC	USDC
Polygon	polygon	USDC	-
Solana	solana	USDC	USDC
Sui	sui	USDC	-

Only send supported assets to your deposit destinations. While other tokens and crypto deposits may be accepted at these addresses, we cannot guarantee their support.

Sending unsupported assets may result in loss of funds. If you accidentally send unsupported crypto, you may be able to recover it using Coinbase’s asset recovery service.

Use cases

Mainnets vs. Testnets

• Mainnet: Live, fully operational blockchain with real transactions and actual assets
• Testnets: Sandbox environments for testing smart contracts, dapps, and other blockchain functionality without risking real funds. You can obtain test currencies from faucets

For example:

Testnet	Mainnet
Base-Sepolia	Base-Mainnet
Ethereum-Sepolia, Ethereum-Hoodi	Ethereum-Mainnet
Solana-Devnet	Solana-Mainnet

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
