Avalanche (C-Chain)
Avalanche (C-Chain) failover support is available for customers on the Growth or Custom plans. Avalanche (C-Chain) failover support is available on Mainnet only.
Avalanche is a Proof of Stake (PoS), layer 1 platform that features 3 built-in blockchains:
Infura provides access to the C-Chain only.
The C-Chain supports the Ethereum Virtual Machine (EVM), allowing Ethereum developers to deploy Solidity smart contract dapps onto the C-Chain. Dapps can run on both Avalanche and Ethereum. Avalanche Platform's C-Chain is EVM-compatible, but it is not identical.
