# Welcome to Candide

A TypeScript toolkit for building Ethereum smart wallets: gas sponsorship, passkeys, batch transactions, and account recovery, all on top of Safe contracts.

## Quick Start[​](#quick-start "Direct link to Quick Start")

```
npm install abstractionkit
```

```
import { SafeAccountV0_3_0 as SafeAccount } from "abstractionkit";

const account = SafeAccount.initializeNewAccount([ownerPublicKey]);
console.log(account.accountAddress); // 0x… deterministic smart wallet address
```

## Why Smart Accounts?[​](#why-smart-accounts "Direct link to Why Smart Accounts?")

Smart accounts eliminate the biggest UX barriers in Web3:

* **No gas tokens**: Users pay fees in any ERC-20 or have them sponsored entirely
* **Modern onboarding**: Login with passkeys, email, or social accounts. No seed phrases
* **Built-in security**: Account recovery, multisig support, and spending limits
* **Batch transactions**: Execute multiple operations atomically in a single transaction

*Smart accounts are programmable contracts, unlocking capabilities impossible with traditional EOAs.*

## Core Features[​](#core-features "Direct link to Core Features")

### Gas Abstraction[​](#gas-abstraction "Direct link to Gas Abstraction")

* Gasless transactions: [Sponsor user fees](https://docs.candide.dev/wallet/guides/send-gasless-tx.md) with flexible rules and policies
* ERC-20 gas payments: Let users [pay gas in any token](https://docs.candide.dev/wallet/guides/pay-gas-in-erc20.md) (USDC, DAI, etc.)

### Modern Authentication[​](#modern-authentication "Direct link to Modern Authentication")

* Passkey integration: [Onchain WebAuthn](https://docs.candide.dev/wallet/plugins/passkeys.md) support for biometric login
* Social login: [Email and OAuth](https://docs.candide.dev/wallet/guides/authentication/.md#social--email) integration

### Advanced Transactions[​](#advanced-transactions "Direct link to Advanced Transactions")
