Integrating wallets

Reference guide for integrating wallet providers with Actions SDK.

Which wallets are right for my use case?

In order to let your users access DeFi, they will need an EVM-compatible wallet. There are plenty of considerations when selecting a wallet schema that works for you:

• Who will maintain custody of funds?
• What permissions must exist for my use case?
• Where in my stack should transaction signatures originate?
• How can my users on and off ramp funds?

Actions SDK supports popular embedded wallet providers to address all of these questions while remaining flexible to your use case.

Embedded Wallet Providers

Embedded wallet providers give your users the ability to sign onchain transactions through your app’s existing email authentication and authorization flows.

Actions works with:

Privy

Turnkey

Dynamic

Gas Sponsorship

Signing and sending onchain transactions requires gas, or fee payment, which adds additional overhead for you and friction for users.

Actions supports gas sponsorship via a combination of smart contract wallets and paymasters. First, configure a paymaster in the chain config by specifying a bundler url. Now, any transactions submitted via an actions SmartWallet on that chain will automatically use your paymaster, therefore eliminating the need for the wallet to pay gas.

Connect your wallet to Actions

Regardless of where and how transactions are signed, Actions has you covered.

1. Choose a wallet provider

   Follow embedded wallet provider documentation and installation steps. Actions works with Typescript clients, both frontend React and backend Node.

2. Import Actions SDK

   Import Actions SDK alongside your chosen wallet provider SDK.

3. Create and fetch embedded user wallets

   Follow embedded wallet provider documentation for wallet creation and access.

4. Pass the wallet to Actions

   Call actions.wallet.toActionsWallet(...), and pass in the provider wallet.

5. Take Action

   The returned Wallet is now capable of calling Actions functions like Lend, Borrow, Swap and Pay!

Smart wallets & signers

In addition to using embedded provider wallets directly, Actions supports the creation of custom smart contract wallets. This additional wallet type is separate from, but still controlled by the owner of the embedded wallet.

If you configure it, Actions will deploy a EIP-4337 compliant Coinbase Smart Wallets on the chains you’ve chosen to support.

Once created, an embedded wallet can be added as a signer on the smart wallet, capable of signing transactions on behalf of the Smart Wallet.
