Multi-Chain Support

The Checks Platform is designed as a multi-chain ecosystem, providing users with flexibility to operate across different blockchain networks while ensuring a seamless experience regardless of their preferred chain.

Initial Blockchain Support

The platform will initially launch on the following networks:

• Polygon (Primary Network): Hosts the CHECK token and serves as the primary network for NFT Checks

• Ethereum: Supports all core features with focus on high-value agreements

• Arbitrum: Layer-2 solution offering lower fees and faster transactions

• Base: Additional layer-2 option for scalability

• BNB Chain: Provides access to the BNB ecosystem

Smart contracts will be deployed across multiple chains to ensure accessibility for users operating on different networks and to leverage lower fees and faster transactions on layer-2 solutions like Polygon.

Network Selection Strategy

The Polygon network is emphasized for its high throughput and low gas costs, which are essential for features such as streaming payments and auto-compounding yields. This makes it ideal for frequent, smaller transactions that would be prohibitively expensive on Ethereum mainnet.

However, by supporting multiple chains, the platform allows users to select the most appropriate network for their specific use case:

• Ethereum: Ideal for high-value agreements where security is paramount

• Polygon/Layer-2s: Better for frequent or smaller transactions where gas costs are a concern

• Alternative Chains: Provides access to different ecosystems and liquidity pools

Cross-Chain Interoperability

Interoperability between chains is achieved via standard bridges or omnichain token standards:

• CHECK Token Bridging: Check Token can be bridged between chains using canonical bridges or solutions like LayerZero's OFT standard, which allows a token to exist natively on multiple chains

• NFT Check Transfers: NFT Checks themselves can be transferred across chains using burn-and-mint schemes or locked states if needed, though initially they will be created and used on the same chain

• Cross-Chain Execution: The architecture considers cross-chain execution – for instance, an NFT Check on Polygon could trigger a payment on Ethereum via cross-chain messaging (using protocols like Chainlink CCIP or LayerZero)

Future Expansion

Post-MVP development will expand multi-chain support further by:

• Integrating additional blockchains to reach an even broader audience

• Enhancing interoperability across diverse blockchain ecosystems

• Implementing more seamless cross-chain functionality

This expansion will ensure that the Checks Platform remains scalable, inclusive, and adaptable to the evolving needs of DeFi users.

Benefits of Multi-Chain Approach

The multi-chain architecture provides several key advantages:

1. Accessibility: Users can access the platform's functionality regardless of their preferred blockchain

2. Cost Optimization: Transactions can be routed to the most cost-effective chain for the specific use case

3. Risk Diversification: Assets and operations are spread across multiple chains, reducing systemic risk

4. Ecosystem Integration: The platform can tap into various DeFi ecosystems for enhanced liquidity and yield opportunities

5. Future-Proofing: The architecture is designed to adapt as the blockchain landscape evolves

Together, these capabilities ensure that the Checks Platform can serve as a truly chain-agnostic financial layer for Web3, allowing users to leverage the strengths of different networks while maintaining a unified experience.
