What to know about Avalanche C-Chain
What the .e suffix means
Tokens such as DAI.e, WETH.e and WBTC.e were bridged from Ethereum and are separate contracts from their Ethereum versions. USDT and USDC on the C-Chain are issued natively.
C-Chain only
Chainhook watches the C-Chain, the EVM chain with 0x addresses. X-Chain and P-Chain addresses are not supported.
Push, not polling
Avalanche C-Chain produces about one block per second. Register an address once and Chainhook pushes each confirmed transfer after 20 blocks, instead of you polling an RPC per address.
