Economy Chain

Overview​

In a multi-chain blockchain ecosystem, efficient asset management presents unique challenges. Traditional blockchain architectures, where each decentralized application (dapp) manages its own tokens, often require users to bridge assets between different chains. This fragmentation can lead to increased complexity, potential security risks, and a suboptimal user experience.

To address these challenges, Chromia has launched the Economy Chain on Mainnet. The Economy Chain serves as the primary infrastructure for CHR token management and economic operations across the Chromia ecosystem.

Core functions​

Centralized token management​

The Economy Chain functions as the central hub for CHR token operations, offering several advantages:

  • Streamlined payments: Dapps can request CHR payments directly from the Economy Chain, providing a standardized payment interface.
  • Proof-based transactions: Users complete transactions on the Economy Chain and provide cryptographic proof to dapps, enabling trustless verification of payments without requiring dapps to directly interact with the Economy Chain.
  • Immediate settlement: Services and assets are delivered upon verification of payment proof, reducing the need for complex escrow systems.

Cross-Chain bridge integration​

The Economy Chain integrates with Chromia's official bridge infrastructure, providing:

  • EVM chain support: Direct bridging of CHR tokens between the Economy Chain and major networks:
    • Ethereum Mainnet
    • Binance Smart Chain

Network fee management​

As the foundation for Chromia's native fee system, the Economy Chain:

  • Processes all CHR-based container lease payments.
  • Manages automated distribution of fees to network providers.
  • Centralizes fee-related operations for improved efficiency.
  • Maintains transparent payment records on a single chain.

This centralized approach to fee management ensures consistent processing while maintaining the security and transparency inherent to blockchain technology.

Account creation​

To interact with the Economy Chain, users must first create an account. There are two methods for account creation:

Method 1: Bridging CHR from EVM-compatible blockchains​

Bridge CHR tokens from Ethereum Mainnet or Binance Smart Chain to the Economy Chain. For detailed bridging information, see the Bridge documentation.

Recommended for EVM users

Choose this method if you already hold CHR on Ethereum or BSC.

Steps:

  1. Prepare your EVM wallet: Ensure you have at least 10 CHR tokens on Ethereum Mainnet or Binance Smart Chain.
  2. Access the bridge: Visit the Chromia Vault or use the official bridge.
  3. Initiate transfer: Follow the bridging process to transfer CHR to the Economy Chain.
  4. Account creation: Your account will be created during the bridging process. If you haven't linked your EVM address to an existing account, you may need to complete the account linking process through the Vault interface.

Method 2: Cross-chain transfer​

Create an account by transferring CHR from any other Chromia chain to the Economy Chain.

For existing Chromia users

Choose this method if you already hold CHR on another Chromia chain (e.g., Token Chain, ColorPool).

Steps:

  1. Source chain account: Ensure you have at least 20 CHR tokens on any Chromia chain (Token Chain, ColorPool, etc.).
  2. Generate recipient address: Create a new account address for the Economy Chain recipient. You can do this by going to Economy Chain on Chromia Vault and click Create Dapp Account
  3. Transfer funds: Send at least 20 CHR to the unregistered address using the Chromia Vault. 10 CHR will be used as a one-time account creation fee, leaving 10 CHR in your account balance.
  4. Account activation: Visit the Chromia Vault to activate your account. The remaining funds will be available in your account after activation.

Technical integration​

The Economy Chain leverages Chromia's core protocols and infrastructure:

  • Implements standard Chromia consensus mechanisms.
  • Utilizes the official bridging infrastructure for cross-chain operations.
  • Integrates with Chromia's provider network for transaction validation.
  • Maintains compatibility with the broader Chromia ecosystem.

Through these integrations, the Economy Chain provides a robust foundation for Chromia's economic operations while simplifying asset management for both users and developers.
