What is this about?

Add official network icon for DaVinci Chain.

Introducing DaVinci Chain combines cutting-edge technology with sustainable practices to create a blockchain ecosystem that's both powerful and environmentally conscious with proof of stake

DaVinci Mainnet
Chain ID: 293
RPC: https://rpc.davinci.bz
Explorers: https://mainnet-explorer.davinci.bz
Validator Explorer: https://validator-explorer.davinci.bz
Chainlist: https://chainlist.org/chain/293

Thrilled to put DaVinci on Metamask.
Looking forward to your support, thank you.

Scenario

As a user, I want to easily connect my MetaMask wallet to the Davinci Chain network so that I can interact with decentralized applications (dApps) and manage DCOIN assets seamlessly without manually configuring network settings.

When the user clicks "Add Network" in MetaMask, the Davinci Chain should appear with its correct RPC URL, chain ID, currency symbol, and logo, ensuring a smooth and trustworthy user experience.

Threat Modeling Framework

Threat Modeling Framework (for technical tasks only)

We follow the STRIDE threat modeling framework to assess potential risks:

• Spoofing:

  • Chain ID uniqueness is enforced (28058), preventing network collision attacks.
  • RPC endpoints served over HTTPS to prevent MITM attacks.

• Tampering:

  • RPC servers are secured with TLS.
  • Only validated smart contracts are recommended for users.

• Repudiation:

  • Transaction history is recorded immutably on the blockchain.
  • All RPC requests are logged internally for auditing purposes.

• Information Disclosure:

  • No sensitive data is exposed through the RPC endpoints.
  • MetaMask and WalletConnect connections are encrypted.

• Denial of Service (DoS):

  • RPC servers are protected using rate limiting, load balancing, and firewall rules.

• Elevation of Privilege:

  • No administrative overrides exist within the client connections.
  • Only user-signed transactions are processed, adhering to EIP standards.

Security Best Practices:

• Full HTTPS encryption on all endpoints.
• OpenRPC schema compliant.
• Minimal metadata exposure to prevent fingerprinting.
• Continuous security monitoring.

Reference Frameworks:

• STRIDE Threat Modeling (Microsoft)
• OWASP Blockchain Security Guidelines
• EIP-1328 (Wallet security improvements)
