Architecture

Overview

The onchain infrastructure that powers Porto consists of the following contracts:

Porto Account

The Porto Account is a keychain that holds user funds, enforces permissions via Keys, manages nonces to prevent replay attacks, and enables secure executions from the account.

Orchestrator

The Orchestrator is a privileged contract that facilitates trustless interactions between the relay and the account.

Simulator

The Simulator is a peripheral utility that enables offchain services to obtain accurate gas estimates for intents in a single RPC call.

Settlement System

The Settlement System enables cross-chain transaction finality through native merkle signature verification. It provides trustless settlement mechanisms for multi-chain intents with interop features including fund transfers, merkle signature verification, and funder interface integration for cross-chain execution.
