Overview

The v2 Wallet API enables developers to programmatically create, manage, and use crypto accounts while CDP secures the private keys and handles complex infrastructure management. Developers can access the v2 Wallet API through either the CDP SDK or CDP’s REST endpoints. With the v2 Wallet API, you can execute token swaps directly from your CDP accounts, combining the power of our Swap APIs with secure transaction signing. This allows you to discover the best prices, create swap quotes, and execute trades in a single call. The following table summarizes the key differences between v1 and v2 Wallet APIs:

Secure key management

Instead of securing your own private keys or needing to set up Server-Signer infrastructure, the v2 Wallet API greatly simplifies crypto key management by signing all of your transactions within a Trusted Execution Environment (TEE). The TEE ensures that sensitive cryptographic material is never exposed to the outside world - not even to Coinbase!
The Trusted Execution Environment (TEE) provides a secure environment for signing your transactions, and ensures that your private keys are never exposed to Coinbase, AWS, or the outside world. Read more in our Security documentation.

​
Single secret authentication

In the v2 Wallet API, a single Wallet Secret grants access to all of your accounts across both the EVM and Solana ecosystems. This single secret is used for sensitive wallet operations, such as account creation and transaction signing.

​
Rotatable Wallet Secret

In case your Wallet Secret is lost or compromised, you can rotate your secret at any time.

​
Multi-network support

Rather than limiting usage to a single EVM network, EVM accounts created using the v2 Wallet API are compatible across all EVM chains. The v2 Wallet API also supports Solana accounts, allowing you to create and manage Solana accounts in addition to EVM accounts.

​
Smart accounts

The v2 Wallet API supports EIP-4337 smart accounts, which provide the following advanced features via smart contract calls:

​
viem compatibility

EVM Accounts in the v2 Wallet API can be used directly with viem as custom accounts. This allows you to leverage viem’s widely-used abstractions seamlessly with the CDP SDK. Refer to the viem compatibility guide for more details.

​
Swaps

The v2 Wallet API enables seamless token swaps and programmatic trading directly from your CDP accounts, empowering developers to build automated trading bots, integrate DeFi swaps into web3 applications, and execute sophisticated trading strategies using Coinbase infrastructure. This powerful integration combines real-time price discovery, competitive quote creation, and secure transaction execution into a single API call, while maintaining the flexibility to use your own wallet and node infrastructure if preferred. Learn more in the comprehensive Swaps guide.
