Transferring assets in blockchain is not as easy as it should be. Wallet addresses are huge and ugly, there is a lot of copy-pasting, and many people use the strategy to make a small transaction - just to be sure everything is ok - before transferring all the assets. In practice, this doubles the transaction fee that the sender has to pay.

To solve this problem, we proposed adatar.me, a funded proposal from Catalyst Fund 6 (back then called ‘Gravatar for ADA Wallets’). We have launched in mainnet in February 2022, and you can check a live demo during our presentation in Gimbalab’s playground here:

https://www.youtube.com/embed/_DiLlr_AxGkThe project is still ongoing, as we are improving the UX, developing the project’s visual identity and working on our API. If you’d like to support us, feel free to send a tip at <https://adatar.me/tip/adatar.me> (:

The current proposal aims at adding an extra feature to adatar.me: an address book. For people who would like to have a list of all their relatives, friends, employees, etc, addresses, this feature will remove the hassle of having to find them through the search mechanism, or even typing different URLs.

We are addressing the follow Challenge's guiding questions/potential directions:

• What needs do users of Cardano have that could be solved by new applications?
• What applications deliver the highest amount of value with the least amount of technical sophistication?
• Integrations with existing products

We see this as a very low risk development. The address book will be linked to one's login and it’s a natural evolution of the features already present in the website. We have the technical knowledge and availability to make it happen.

The development of adatar.me widget is going to follow the road map presented below:

August

• Address book UX design

September

• Commence of address book development

October

• Integrate the address book to adatar.me

Budget

• UX design: $1k
• Software engineer (part-time): $4k/month, $8k for 2 months
• Project management: $1k
• Total: $10k

Internally, we will use the Agile methodology to manage and keep track of our progress on this project’s development.

Externally, for audit purposes, we will track the progress according to the delivery of the milestones presented in the roadmap included in the feasibility section of this proposal. This progress report will be done through the monthly meetings with the challenge team and coordinator meetings with the IOG team.

Success for this proposal is to successfully develop the adatar.me address book and to have users utilizing it to facilitate their asset transfers on Cardano.

• <u>After 3 months</u>: Address book successfully developed
• <u>After 6 months</u>: At least 50% of Adatar active users by the tima have created address books.

This proposal is an extension of a previously funded proposal: <https://cardano.ideascale.com/c/idea/367448>. At the time, the project was called ‘Gravatar for ADA Wallets’, but it was renamed to ‘adatar.me’.
