Smart contract sub-layer

Focus: Business logic, contractual agreements, and automated execution in a crosschain context.

Objective: Facilitate the definition, deployment, and execution of decentralized application logic and contractual agreements across chains, ensuring consistent, trustless, and compliant operations.

Description: Smart Contract Layer in ensuring that business logic and contractual agreements are seamlessly executed across different blockchains, while also adhering to the necessary regulations in the given setting. This layer ensures that smart contracts on one chain can be recognized, triggered, or even deployed on another chain. Especially in regulated environments, this layer also ensures that these contracts adhere to legal and regulatory requirements, and can potentially integrate with oracles or other external systems to fetch necessary data or validate conditions. The smart contracts serve as a bridge for business logic, ensuring operations across chains are coordinated, consistent, and compliant. Provides standards and tools for writing smart contracts such that they can interoperate across different blockchain platforms and networks.

Layer owner: Smart contract developers, legal experts specializing in digital contracts, regulatory bodies providing guidelines for compliant smart contracts, and organizations or consortiums setting standards for crosschain smart contract operations.

Some key aspects:

• Standardized contract interfaces, APIs and ABI specifications

• Portable execution environments (e.g. EVM)

• Alignment of contract lifecycles across chains

• Mapping between contract object models

• Libraries and frameworks for cross-chain contract development

• Management of contract registries and versions across chains

• Handling of contract events and callbacks across chains

• Consistent contract testing frameworks
