User Accounts

Account Creation

Brewit accounts are implemented as Safe Accounts (formerly Gnosis Safe) that comply with ERC-4337 Account Abstraction and ERC-7579 specifications. This implementation provides:

Full compatibility with ERC-4337 infrastructure
Enhanced security through modular validation
Flexible authentication mechanisms

Technical Implementation

Each Brewit account is deployed as an ERC-7579-enabled Safe Account with the following configuration:

{
"owners": ["authenticatedSigner"], // Single owner based on auth method
"version": "1.4.1",
"entryPoint": "0x5FF137D4b0FDCD49DcA30c7CF57E578a026d2789", // EntryPoint v0.7
"validators": [
], // Based on auth method
"executors": [],
"attesters": [
"RHINESTONE_ATTESTER", // is the address of the Rhinestone attester
"ZENGUARD_ATTESTER" // is the address of the Zenguard attester
],
"attestersThreshold": 1, // Number of attesters required for module attestation
"safe4337ModuleAddress": "SAFE_7579_ADAPTER", // is the address of the Safe 7579 adapter module
"erc7579LaunchpadAddress": "ERC7579_LAUNCHPAD", // is the address of the ERC7579 Launchpad contract
"safeSingletonAddress": SAFE_SINGLETON // is the address of the Safe Singleton contract
}

This configuration could be used to generate a Safe Account using library like permissionless.js Refer contract deployments for more details:

Authentication Methods

Brewit supports multiple authentication strategies, each implemented with specific security considerations:

1. Dynamic Embedded Wallet Authentication

Use cases: Email and Social logins (Google, Twitter, Farcaster) Technical implementation:

Utilizes Dynamic Embedded Wallets
Wallet is added as both owner and validator of the Safe Account
Currently uses Trusted Execution Environment (TEE) for key management
Planned migration to Threshold Signature Scheme (TSS-MPC) for enhanced security

Dynamic Embedded Wallets uses TEE for key management and signing but soon will be ported to TSS-MPC for better security.

2. WebAuthn Passkey Authentication

Implementation details:

Integrates Rhinestone-attested WebAuthn module
Compatible with ERC-7579 specification
Originally developed by ZeroDev for Kernel Accounts
Custom passkey service for additional platform authentication

We run our own Passkey service to also authenticate the user for various other services.

3. External Wallet Authentication

Features:

Direct integration with existing crypto wallets
Wallet becomes primary signer and validator
Supports all major Web3 wallet providers
Compatible with both EOA and smart contract wallets
