Smart Contract Stack

The UGOLDX platform is already built around a real smart-contract foundation rather than a single isolated token contract.

Core contract families

The deployed and expanding contract stack includes four major layers:

1. Token and treasury layer

This layer supports the digital asset model itself:

• token contracts
• token-related treasury and distribution controls
• associated support contracts used to move, manage, and route ecosystem value

2. Smart-account layer

UGOLDX is already moving beyond simple externally owned account flows and into a contract-based account model designed for stronger UX and more flexible execution.

Representative deployed account-contract families include:

• EIP7702Proxy
• Simple7579Account

These contracts form the basis for programmable user execution, stronger recovery and authorization options, and a better path toward advanced wallet functionality.

3. Validator and authorization layer

Smart accounts become more powerful when authorization can be expressed in multiple controlled ways.

Representative validator families already deployed include:

• WebAuthnValidator
• SessionKeyValidator

This allows the platform to build toward more practical and secure approval models, including passkey-oriented user security and controlled session-based execution flows.

4. Sponsored execution and token-gas layer

The platform also includes a deployed fee-sponsorship and token-gas foundation.

Representative families include:

• VerifyingPaymaster
• ERC20Paymaster
• ERC20PaymasterUsdc
• ERC20PaymasterUsdt

These contracts are important because they support a more modern execution model in which:

• selected transactions can be sponsored
• users can move toward paying network costs with supported tokens rather than relying only on native gas assets

Why this matters

This contract stack changes what the platform can become. Instead of remaining a simple token-and-balance experience, UGOLDX can grow into a more capable execution environment with:

• smarter wallet behavior
• better onboarding flows
• more flexible payment experiences
• stronger long-term product utility

The result is a contract foundation that is already meaningful today and strategically expandable for tomorrow.
