Lido is a liquid staking protocol for certain blockchains using Proof-of-Stake (PoS) consensus mechanism. Users can deposit ETH in exchange for stETH at 1:1 on the Ethereum network. According to the launch of Beacon Chain, you need to stake at least 32 ETH to earn rewards. Lido is another way for you to do so, as you can take any amount of ETH to earn staking rewards and swap back to ETH anytime. There'll be a daily update on your stETH balances, which includes the staking rewards.
stETH is a token that represents your staked ETH in Lido. You can hold stETH to earn staking rewards. Staking with Lido, stETH is minted upon deposit and burned when redeemed. Total assets including the staking rewards will be updated daily to your stETH balances.
Due to the configuration of OKX Wallet rules, you may not be able to see the stETH. Instead, you can go to "ETH" via "Wallet ⇾ DeFi ⇾ Lido" to see the details of your stETH. Or, if you still want to see the stETH in your wallet, you can manually configure it via "Wallet ⇾ Crypto ⇾ Manage crypto".
