Migrating DApps to CAGA: A Developer’s Roadmap for EVM Compatibility

Introduction

Developers often face challenges when moving decentralized applications (dApps) from expensive or congested blockchains to more efficient ones. CAGA Network, with its EVM compatibility, offers a compelling alternative: low fees, high speed, and straightforward migration for projects already built in Solidity.

Why Move to CAGA?

• Lower Transaction Costs: Approximately $0.02 per transaction, appealing for dApps with frequent interactions.
• Scalable Throughput: Up to 560 TPS means dApps can scale without congestion issues.
• Developer-Friendly: CAGA’s EVM compatibility lets you reuse most of your existing code, libraries, and tooling.

Prerequisites

1. Solidity Codebase: Your dApp’s smart contracts in Solidity (as commonly used on Ethereum).
2. CAGA-Compatible Wallet: Tools like MetaMask (where you can add CAGA as a custom network).
3. Familiarity with Standard Ethereum Tooling: Truffle, Hardhat, or Remix can all deploy to CAGA with minor config changes.

Step-by-Step Migration Guide

1. Add CAGA Network to Your Wallet
   • Network Name: CAGA Network
   • RPC URL: https://www.ankara-cagacrypto.com/
   • Chain ID: 72778
   • Symbol: CAGA
   • Block Explorer URL: https://explorer.ankara-cagacrypto.com/
2. Update Deployment Config
   • Adjust truffle-config.js or Hardhat’s networks config to include CAGA’s RPC endpoint and chain ID.
   • Confirm gas settings match CAGA’s requirements (though fees are substantially lower than typical Ethereum mainnet values).
3. Redeploy Smart Contracts
   • Use your chosen framework’s standard deployment commands.
   • Verify that your contracts compile and deploy without errors.
   • If you rely on advanced Ethereum features (like chainlink oracles), ensure equivalent services are available on CAGA or plan alternatives.
4. Test on CAGA
   • Interact with your newly deployed contract on the CAGA testnet if available.
   • Check transaction finality (~1 second) and confirm logs/values.
5. Verify on Block Explorer
   • If CAGA Explorer supports contract verification, upload your Solidity source to maintain transparency.
   • Confirm the explorer recognizes your contract and you can see transaction details as expected.
6. Front-End Configuration
   • Update your dApp’s front-end to use the CAGA network. This generally involves changing the RPC URL and chain ID.
   • Provide a UI toggle so users can switch between Ethereum and CAGA if desired.

Common Pitfalls & Solutions

• Deployment Errors: Often resolved by adjusting gas limits or verifying the chain ID is correct.
• Missing Dependencies: If your dApp depends on specialized Ethereum tooling (like certain oracles), you may need CAGA-compatible equivalents.
• User Education: Provide instructions for end users to add CAGA to their wallets and obtain any required tokens for gas.

Performance & Cost Advantages

• Real Example: A typical NFT mint on Ethereum can cost anywhere from a few dollars to tens of dollars in gas fees. On CAGA, that same process may cost just a few cents—allowing more frequent interactions without user pushback.

Conclusion

Migrating your dApp to CAGA takes relatively little effort thanks to its EVM compatibility, and the benefits—lower costs, near-instant confirmations, and less congestion—are substantial. By following the steps above, developers can seamlessly bring their projects into an environment primed for growth.
