Frontend Builder Technical Guidance

Building with the Symmio architecture

Symmio is built on a modular architecture: the Diamond Standard for upgradeable contracts, the AccountLayer for account management, and a set of specialized facets that handle trading. This section is the guide to those core components, whether you're building a frontend or a utility on top of the protocol.

To build a trading bot with Symmio, see Building a Trading Bot.

Overview

These pages explain how the Symmio ecosystem is structured and how the pieces fit together: modularity, upgradeability, and separation of concerns, and how those choices keep trading secure and efficient. What's covered:

• Diamond explainer: the Diamond Standard (EIP-2535) at the core of Symmio, including facets, selectors, and storage management.

• Account creation and funding: creating a sub-account, then depositing and allocating collateral for trading.

• Sending and closing quotes: opening a trade by sending a quote, and the standard close flow, including the states involved and the roles of PartyA and PartyB.

• Instant trading: the instant-open and instant-close variants for immediate execution, and the trade-offs against the standard flow.

Each page includes function signatures, example usage, and event descriptions.
