To truly achieve the on-chain integration of RWA (Real-World Assets), it is not only necessary to have a concept but also to have robust underlying technology. The technical architecture of STO Chain combines advanced components such as Cosmos SDK, Ethermint, and IBC, paving the way for asset digitization.

Technical Overview: Cosmos SDK + Ethermint

The development foundation of STO Chain is Cosmos SDK — a framework for building blockchain applications in a modular way. It allows developers to customize modules freely based on asset types (such as valuation, identity verification, KYC, etc.).

On the other hand, the platform achieves EVM compatibility through Ethermint, supporting the direct deployment and migration of Solidity smart contracts.

Consensus Mechanism: CometBFT + PoS

The network adopts a BFT-based CometBFT consensus mechanism to ensure fast and secure transactions. Combined with the PoS staking mechanism, users can participate in governance and security validation by staking STOC tokens, enhancing the network’s decentralization.

RWA Modular Architecture

• Asset registration and tracking: provides registration interfaces for asset metadata, ownership, valuation, and more;
• Compliance module: Built-in KYC/AML review process to ensure the authenticity and legality of user identities.
• Data Access: Access real market data through Oracle, updating asset values in real time;
• Governance Mechanism: The modular governance system supports on-chain proposals and voting, ensuring community-led development.

Smart contract and compliance support

All asset behaviors of the STO Chain are controlled by smart contracts. The system supports

• Multi-class token standards: including asset class (RWA), compliance class, governance class;
• Upgrade mechanism: Adopts a proxy contract architecture to support future iterations;
• Reporting Mechanism: On-chain records and automatic reporting achieve audit compliance automation.

Application prospects and ecological potential

STO Chain is not only limited to asset issuance but also supports the development of DeFi products based on RWA, such as:

• Mortgage
• On-chain insurance
• RWA-backed stablecoin

In the future, STO Chain is expected to become the infrastructure connecting traditional assets with the on-chain ecosystem.
