​
Overview

Our platform introduces a seamless integration between and accounts. This page outlines the technical steps and security measures for developers to efficiently manage AA accounts via our SDK.

​
Creating AA Accounts

Creating AA account is done under the hood using underlying AA-provider ZeroDev.

Each EOA links to a unique AA account, effectively acting as a 1-to-1 relation.

​
Key Features of SDK for Adoption of AA and Yield on Idle Assets

  • Transaction Conversion: Simplify the conversion of standard transactions into user operations (UserOps) for various actions including swaps, transfers, NFT activities etc.
  • Batch Operations: Aggregate and dispatch UserOps in batches for increased transaction efficiency.
  • Simulation: Use SDK to generate regular transactions, compatible with regular simulators’ APIs
  • Session Keys: Utilize session keys for secure, permission-based management of AA accounts, enabling automated yield on idle assets.

​
Day-to-Day Workflow

1

Linking EOA to AA

Automatically create an AA account for each user’s EOA, establishing a secure link for transaction management.

const aaClient = new savingsSDK.AAClient(eoa);
console.log(aaClient.getAAAddress());
// No smart contract deployed yet at this point, it is deployed with first
// transaction sent.
2

Sending a regular transaction from AA wallet

Use the SDK to transform transactions into UserOps.

// const transaction = generateSwap(...);
const userOp = savingsSDK.convertTransactionToUserOp(transaction);
const receipt = await savingsSDK.signAndSendUserOp(userOp);
3

Simulate assets movement

SDK provides the ability to simulate UserOps using regular simulation methods (RPCs, Alchemy simulation, Tenderly, etc).

// const swapTransaction = generateSwap(...);
const userOps = await savingsSDK.signUserOps();
const transactionForSimulation = savingsSDK.userOpsToTxn(userOps);
const erc20Transfers = new AlchemyClient(ALCHEMY_API_KEY).simulate(userOps);

​
Activating Yield with Session Keys

Assign session keys through the SDK to enable automated yield generation, with explicit permissions for transparent security.

const toBeSigned = savingsSDK.prepareSessionKey();
const signature = await signFromBehalfOfUser(await savingsSDK.prepareSessionKey);
savingsSDK.notifyOfSignature(signature);

Session keys are rigorously audited and can be revoked by wallets at any time, providing end-to-end control and security for users’ of AA accounts.

​
Summary

Our architecture prioritizes security, supported by thorough testing and validation to ensure a resilient and user-friendly integration process. Developers can leverage our SDK and infrastructure to offer a sophisticated yet straightforward wallet experience, emphasizing safety, efficiency, and yield generation.
