# ERC721s

Revolutionary standard

We introduce a revolutionary standard for Ethereum-based NFTs – ERC721s. Developed by IDNTTS Founder filio.eth.

It is a tiny yet powerful improvement to the original ERC721 standard, that enables many new use cases and substantially improves UX for the existing cases.

Consider the features of NFTs implementing ERC721s:

* Borrow an NFT for just a fee, without any huge collateral
* Stake your NFTs without actual staking
* Pay for your NFT in small installments
* S is for Safety: lock your NFT and declare your safe cold wallet as unlocker

Our official partners Angry Dolphins launched on our ERC721s contract and mass adoption is behind the corner!
