DFGC has been developing several DeFi & NFT projects. They are ongoing in an undisclosed manner in order to protect our ideas & codes from being stolen.

The purpose of publishing this report is to secure transparency of our development activity to some extent & increase public awareness of our activity to attract people to join & be contributors to our community.

Progress Report


Core Development

The first audit report has been finalized. Soon the report will be published ahead of the repository release.

The second audit has been temporarily put on hold as no critical Yamato-specific issues were found during the first audit.
We will proceed with a second audit at the time of version upgrade or post-launch significant TVL increases.

Meanwhile, we are in process setting up a bounty on Immunefi as an alternative to a second audit. Scheduling listing on Immunefi once the repository is released.

In November, we conducted an exhaustive verification of state change patterns using the Fuzz test & currently working on the following:

  • Check how to manage contracts deployment & upgrades by multi-sig
  • Fork main-net environment
  • Confirm test sequences

We are on track to address the multi-sig management practices for deployments and upgrades hence we have tested contracts deployment & upgrade on Goerli network in March.

After confirming the differences between the test net and the main net, we proceeded to the mainnet launch.

Interface Development and has been deployed for production environments. Current development environment, will be used as an interface to verify additional functions on the test net after the main net launch.

With the deployment on Goerli, all settings for Rinkeby have changed to those for Goerli.

All required functions for V1 have already been implemented and are confirmed to work properly.

We plan to proceed with developments for V1.5 and V2, while any requests for improvement from users to be assessed & reflected through developments.


The draft docs are tentatively published in Gitbook. If there are any typos or unclear points, please advise us in Discord.


Core Development

Our PoC is a catalog application to exchange reward points and gifts in the NFT.

A prototype of the web application is on live. It performs SIWE (Sign In With Ethereum) and transfers points in the NFT held by the EOA to other NFT.

Due to non-atomic nature (possible transfer of the NFT to another EOA after login & double login at the other EOA) we are considering implementing an off-chain solution.

NFT Image Development

We are in the process of designing NFT images to be issued by DFGC.

Our plan is to issue 2D images or 3DCG videos. Setting up a variety of frame shapes, texture, and themes are in the development plan.

Logo Competition

The logo competition initiative is led by the Design Department. Meanwhile we are open to receive any drafts or design motif proposals to have further discussion.

Please join the YADORI Logo Competition thread.


YASHIRO is an NFT that evolves its design based on the status of EOA (number of ETH holdings, number of transactions, etc.) and it represents the identity of EOA.
It is also a platform for Avatar’s illustration by designers.

Core Development

The implementation of contracts, image selection engine, and landing page is ongoing.

Tokenomics draft is in discussion. This is to ensure project stability & sustainable future development through introducing a utility token.

The landing page will be published once all specifications document is prepared.

NFT Image Development

Development is currently led by the Design Department.

Themes of avatar model in V1 are followings

  • Modest representation of “Wa” (Japanese cultural concept)
  • Crypto and sense of festivity
  • Ennui emotional expression that owners feel an affinity

We continue to refine designs and will share them on Discord.

We plan to expand the range of expression by having multiple avator models from various designers. If you are a designer please reach out NFT Department to learn how to contribute your model/character into the Wallet Avatar NFT.

Logo Competition

Snapshot voting for YASHIRO Avatar NFT Logo went to Proposal B, which received the most votes.

Going forward the official logo will be used in all materials including landing pages. Thanks to all $TXJP holders who voted.

ーTXJP Analytics Siteー

As a first step of building a community dashboard, we have started to assess, design, and implement an analytics site that allows users to check statistics such as TXJP holders trend.

The site facilitates community members and others to assess risks such as large TXJP token holders, and contributes to maintaining the health of the community.

For new community members the dashboard makes it easier to instantly understand and catch up with overall community status.

A prototype can be found here

Currently, we are developing and checking the operation in a private repository, but as soon as we confirm stable operation and license of the source code, it will be released as OSS, and to be open for your Commit.

This is not a DApp however it has a significant impact on further development of the community.

Community dashboard roadmap is here.


Yabumi is a token transfer platform based on SNS account authentication. Usual token transfers addresses a receiver’s address however Payroll-NFT address the NFT holding address authenticated by SNS Auth for token transfers.

This is how it works in specific:

  1. A receiver mints NFT using SNS Auth (SNS account and tokenID has linked)
  2. A sender select the receiver’s SNS account & token amount to transfer
  3. Payroll-NFT resolves linkage among SNS account, tokenID and owner/address.

This eliminates communication between sender and receivers about wallet addresses.

The PoC targets DFGC contributors & allow them to mint NFTs using Discord authentication and receive payroll & rewards.

PoC Testing

Contracts including core functionalities of Payroll-NFT, namely Minting and token transfer, has been deployed on the Goerli testnet.

We are tweaking settings and dependencies for the mainnet launch.


Several issues has been found during the testing and teams has working on bug fixes, adding new features and improving security. Here is the Discord’s channel payroll-nft-ama to report issues or suggestions from those who has participated in the testing.

Naming Competition

The final Snapshot Voting for the naming competition has ended, and the official name of Payroll-NFT has been decided as Yabumi by the highest number of votes.

Through the competition 24 entries were submitted. We thank everyone for their participation.

-Merkle Distributors-

We are developing a airdrop tool using Merkle-tree. The contract has been developed and the UI is under development.

Workflow specification:
#1. the Distributor decides on eligible address & quantity in the UI.
#2. compress the information of #1 into a Merkle-tree, register it in the contract, and deposit a token
#3. the owners of eligible address claim tokens from the UI and tokens are transferred.

This tool is enable distributor to determine amount of token to be distributed based on ownership of specific token in a designated block height. It is planned to be used in our airdrops to TXJP holders going forward.

PoC test will be conducted in coming weeks.

Naming Competition

Similar to previous projects, naming competition to select official name for the product package has begun. It is open for anyone to submit applications(as many as you like) at discord General Forum.

Vacant Positions



Yamato Interface (GitHub) is OSS.Anyone can submit and respond to issues.
We are looking forward to having your Commit to make the Yamato Interface even better.
If you have any suggestions for UI/UX improvements, please post here.


Core Development

  • Landing page (front and design) developer
  • Server developer for exchange, redeem or grant points.

In the future it will be on-chain (using ERC3525) however current PoC aims to build on the Web2 tech stack. If you are interested, please join our Discord and reach out us.

NFT Image Development

We are looking for illustrators and designers to design NFT images and models. If you are interested, please check NFT Department in Discord.


Spot tasks are posted on Dework.

If you are interested in a task, please post your interest in the task application thread on our Discord.Let’s start from defining the requirements and negotiating compensation of each task.
