Questar

Overview.

Quest platform.Users can complete several quests and receive points (tokens).Quests include quizzes and campaign tasks for various projects.When a certain number of these tokens are accumulated, the NFT is minted (`ERC404`, `DN404`...).NFTs themselves can be bought and sold, but selling NFTs will reduce the points (tokens) by that amount.Conversely, buying NFTs increases points.This allows users to satisfy their desire for collection and enjoy the game as if it were a gacha.The advantage for the project side is that it makes it easier to provide on-chain information.For example, "how many NFTs a particular address has", "number of transactions", "multi-chain support", etc.

Campaign tasks.

Asking users to perform specific tasks, mainly on Giveaway and Airdro, is commonplace in current Web3 projects.Commonly used tools include [gleam](https://gleam.io/).X collaboration, X Post Like and Re-Post, Discord collaboration and the resulting draw.Not a very on-chain specific service, so not suitable for obtaining on-chain information, e.g..Information such as 'number of specific NFTs held by a specific address', 'holding period', 'number of transactions over a period of time' could be obtained to better reach the users they want to reach.In addition, "multi-chain support" provides an experience that is not limited to EVMs.

ERC404 and DN404

A system that allows NFTs to be minted after holding a certain number of FTs.If the NFTs are sold, the FTs are lost.It can also be used for long-term holdings of NFTs or FTs themselves.

Users.

The campaign task itself is simple.The task itself is so simple that it is honestly a pain in the ass.Users receive points (tokens) for completing tasks, and NFTs can be issued once a certain number has been accumulated, so motivation is generated, such as completing tasks to draw gachas.Consideration is also given to stimulating the desire to collect NFTs by issuing NFTs in collaboration with companies.

Concerns.

Certain projects issue too many campaign tasks.

As a result of this, a certain number of tokens should be deposited when campaign tasks are carried out, as points are received too often.This prevents campaign tasks from being shot in vain.In addition to this, the deposited tokens are used to pay for gas for issuing points (tokens). It is expected that the speed of the aptos chain would allow for almost real-time token issuance.

The details of the ERC404 implementation are summarized in the article for better understanding.

[ERC404大全](https://zenn.dev/heku/books/ae7f350cca6e46)

Implemented ERC404 in the Move language.

Unlike the ERC404 implementation, the NFT and ERC20 token contracts are created separately.

The reason may be that they do not appear on Marketplace. and separation of responsibilities.
