merkle-distributor VS lido-dao

take all the traits, concat them into a single string, hash it. Use all the NFT in order of id and then hash them together to create a merkle tree root. From their you can prove you own a leaf in the root, aka u own the nft and its traits. This is a reference kinda https://github.com/Uniswap/merkle-distributor

Most airdrop are done with merkle drops like uni https://github.com/Uniswap/merkle-distributor

Example: https://github.com/Uniswap/merkle-distributor

And better yet one that could help us airdrop to a list of 80k eth addresses with a merkle distributor? https://github.com/Uniswap/merkle-distributor

Have you seen the Uniswap Merkel distribution contact used for the UNI distribution? It’s awesome. They rolled up address and balance for a huge number of eth accounts in a Merkel tree Then you seed the contract with the proof. Not sure about how to have BTC address sign a message that is validated on Eth contract but it’s worth looking at if you’ve not already checked it out. Uniswap Merkel Distributor

Lido hace rebase con la fórmula a continuación:

Firstly, the APR displayed on https://lido.fi/ is a 7-day MA estimate. Secondly, 'protocol APR' is just the APR for the protocol, and not for users, so it's not taking into account the 10% fee.

Best to ask lido directly on their discord channel - link avail at the bottom of their main page https://lido.fi/

One solution you do have is liquid staking. Polygon Labs has a great writeup on liquid staking here. MATIC liquid staking is still done on ETH, but you can swap your native MATIC tokens for stMATIC, which are bridged liquid-staked MATIC tokens through Lido Finance.

Lido also makes up for 77% of ALL staked ETH deposited through LSDs the highest it's been all year.

"Can periodically query the current share rate (as shareRate = lido.getTotalPooledEther() * 1e27 / lido.getTotalShares()) and if the number change more than a few WEIs (see https://github.com/lidofinance/lido-dao/issues/442), than calculate APR like presented https://docs.lido.fi/integrations/api/#last-lido-apr-for-steth would need to save the timepoints as well can query and remember the reported oracle frames https://github.com/lidofinance/lido-dao/blob/master/contracts/0.8.9/oracle/AccountingOracle.sol#L440 https://etherscan.io/address/0x852deD011285fe67063a08005c71a85690503Cee#readProxyContract#F19"

The official Ethereum staking APR is 4.639% (source : https://beaconcha.in/ethstore ) Lido's staking APR is 3.8% (source : https://lido.fi/ ) but they take a 10% fee on rewards when you withdraw, so the real Lido APR is in fact 3.8*0.9 = 3.42%

What made you certain that it is legit? Steps taken? Verify on lido.fi site, this sub, etc?

You can also swap to stETH direct from Lido at https://lido.fi/ at a price of 1:1.
