 ## Ethereum 1.0 deposit contract
 
-The initial deployment phases of Ethereum 2.0 are implemented without consensus changes to Ethereum 1.0. A deposit contract at address `DEPOSIT_CONTRACT_ADDRESS` is added to Ethereum 1.0 chain defined by `DEPOSIT_CHAIN_ID` and `DEPOSIT_NETWORK_ID` for deposits of ETH to the beacon chain. Validator balances will be withdrawable to the shards in Phase 2.
