How It Works

RISE Wallet is built on top of Porto, a next-generation account stack for Ethereum that leverages EIP-7702 for native account abstraction. With our backend & SDK customised to utilise RISE high performance in addition to providing chain wide gas sponsorship for real users. This page explains how RISE Wallet works under the hood.

Architecture Overview

RISE Wallet consists of three main components:

1. Smart Account Infrastructure

Porto Smart Accounts: Audited contracts that provide account abstraction features
EIP-7702 Integration: Native account abstraction without smart contract wallets
Key Management: Support for multiple key types (P256, secp256k1, WebAuthn)

2. Relay Infrastructure

Gas Sponsorship: Automatic gas payment for eligible transactions
Transaction Batching: Bundle multiple operations into single atomic transactions
Circuit Breakers: Safety mechanisms to prevent abuse and overspending

3. Dialog Interface

Passkey Authentication: WebAuthn-based login with biometrics
Cross-Platform Support: Works on web, mobile, and desktop
Session Management: Secure storage and handling of session keys

Transaction Flow

When a user interacts with RISE Wallet, the following process occurs:

User Action

User initiates a transaction (transfer, swap, mint, etc.)

Wallet Dialog*

RISE Wallet dialog opens to handle the request

*Session Key Optimization

When a valid session key is available, this step is bypassed entirely. The transaction is signed automatically without requiring user interaction, enabling seamless high-frequency actions.

Authentication Check

The system checks if a valid session key exists:

Has Session Key → Sign automatically with session key
No Session Key → Request user signature via passkey

Relay Processing

The signed transaction is sent to the RISE Relay for processing

Sponsorship Validation

Relay checks sponsorship rules:

User tier and daily limits
Whitelisted contracts
Allowed functions

Network Submission

Valid transaction submitted to RISE network

Instant Confirmation

Shred confirmation received in ~3ms via WebSocket

Key Technologies

EIP-7702: Set Code Transaction

EIP-7702 allows EOAs (Externally Owned Accounts) to temporarily delegate their functionality to smart contract code during a transaction. This enables account abstraction features without deploying a smart contract wallet, while maintaining compatibility with existing Ethereum infrastructure. Read more about EIP-7702 here.

WebAuthn & Passkeys

RISE Wallet uses WebAuthn for authentication, supporting biometric login methods like FaceID, TouchID, and Windows Hello. Keys are stored securely in the device's secure enclave and can sync across devices via cloud providers.

Session Keys

Temporary keys with specific permissions enable apps to act on a user's behalf within defined limits. This allows high-frequency actions without user interruption, while maintaining safety through time and spend limits.
