What is the primary role of the C-Chain in Avalanche's toolset?

• A. Hosts the EVM and supports Solidity-based contracts
• B. Manages network governance proposals
• C. Handles validator metadata
• D. Stores finality thresholds

Answer: (A)

The C-Chain is Avalanche’s Ethereum-compatible smart contract chain. It runs the Ethereum Virtual Machine (EVM) and supports Solidity-based contracts, which lets developers write and deploy Ethereum-style smart contracts on Avalanche, taking advantage of its fast finality and low fees.

This contrasts with the other chains in Avalanche: the X-Chain is designed for asset transfers, and the P-Chain coordinates validators and subnets. Governance logic and validator metadata aren’t primarily functions of the C-Chain, and finality thresholds are part of the underlying consensus, not a single chain’s role. So the C-Chain’s primary purpose is to host and execute Ethereum-compatible smart contracts using Solidity.
