After more than a month of product development by the technical team, we launched the first public beta version of Linkkey app - v1.0-alpha.

There are still some bugs in the product, which we are still fixing, and we expect to launch the official version of the main network at the end of September.

We will explain the features of Linkkey-app one by one as below:

• Follow-NFT

• Group-NFT

• Market

• Profile

• Chat

• Circle

Follow-NFT

Follow-NFT is the basis for building Web3 social circle, we will define friends relationship based on blockchain's NFT holding status, and friends can conduct encrypted chat (based on XMTP protocol), post articles (based on Lens Protocol protocol) and other behaviors between friends.

Follow-NFT is a financial exploration of the Web3 social circle, where we price the relationships and can trade them freely. This makes relationships in Web3 social circles valuable, and users will be more active in participating and maintaining social relationships, which ultimately makes social circles more meaningful and thus retains Web3 users.

In fact, the social giants in the traditional Web2 domain are already experimenting with private circle socialization, specifically such as Twitter circle (https://help.twitter.com/en/using-twitter/twitter-circle).

We have the advantage of a native Web3 social circle developed on the blockchain, and a more convenient social financialization through cryptocurrency.

The prerequisite for issuing Follow-NFT (hereinafter referred to as FNFT) is: having an SNS domain name and completing Twitter identity verification.

FNFT basic information:

• NFT quantity is 150

• Fixed floor price = 10 KEY, the default KEY as the currency unit, the subsequent will be open to other currencies

• Can set the number of external public sales (primary market, open to external Mint)

• Secondary trading is possible

After issuing FNFT:

• SNS can no longer be traded and will be locked into designated contracts to avoid fraud and false issues

• Group-NFT can still be issued

• One-time Mint is required for those not sold to the public

Group-NFT

Group-NFT is a social supplement to Follow-NFT, we have 1v1 social needs, but also a group of like-minded people for group social needs, so we also launched the Group section, for up to 1500 people to build a large social circle.

The prerequisite for issuing Group-NFT (GNFT for short below) is: having an SNS domain name and completing Twitter identity verification.

GNFT basic information:

• NFT quantity is 1500

• Fixed floor price = 2 KEY, default KEY as currency unit, will open other currencies later

• Can set the number of external public sales (primary market, open to the public Mint)

• Secondary trading is possible

• Can set the name of the contract group, easy to spread and remember

After issuing GNFT:

• SNS can no longer be traded and will be locked into designated contracts to avoid fraud and false issues

• FNFT can still be issued

• The unpublicized portion will be minted to your own address

Market

Market is located in the dedicated NFT market, can be traded Follow-NFT and Group-NFT, subsequent versions will support the transaction of SNS domain names.

Support for NFT transactions with KEY, subsequent versions will support USDC, Matic.

Fixed contract issuance service fee, 2.5% transaction service fee.

Support setting royalty fee.

Service fee

1. Issuance service fee will be charged when issuing contracts:

   • 100 key for issuing Follow-NFT

   • 500 key for issuing Group-NFT

2. 2.5% of the transaction amount will be charged as a service fee when a transaction is made by a trading contract.

Royalty fee

The issuer of Follow/Group NFT can set a royalty fee of 0-10%, which can be extracted from the secondary flow of subsequent NFTs.

Royalty income is transferred directly to the publisher's account through the contract.

Profile

Profile is the base object of Linkkey protocol, which is a contract on Polygon chain and constitutes a relationship mapping with SNS NFT, which is the Web3 DID we built and mainly serves the social circle scenario.

Profile has rich attributes and good scalability, and adopts a scalable contract scheme to achieve compatibility with the future.

In simple terms, SNS + Profile is an upgraded version of ENS.

Chat

Chat is an important function of Linkkey to realize Web3 social circle.

Chat is built on the XMTP protocol, which enables 1v1 chat and group chat without creating an additional account and using a wallet for signature to open the chat, and the chat messages are coded and encrypted by standard codec for privacy security.
