Code

HordETHStakingManager.sol

Address

HordETHStakingManager is deployed at 0x5bBe36152d3CD3eB7183A82470b39b29EedF068B on the Ethereum mainnet.

Overview

HordETHStakingManager(HETH) is upgradeable contract where users can deposit ETH in order to stake and earn validator rewards, redeeming of deposit is not possible yet, but it will be after the Shanghai Hard Fork.
