Please describe your proposed solution.

Multisig wallets are in essence a security feature for the users of a protocol, they allow hardening your security against any number of threats and dangers, including but not limited to stolen keys, coercion, destroyed keys or holder being incapacitated and more.

To provide the kind of reliability and safety our ecosystem is known for we don't just need to have an easy to use multisig wallet, but we need to take all processions needed to make sure it will function in the way intended and no funds can be stolen due to a bug or exploit.

By funding this proposal we can do exactly that.

Please define the positive impact your project will have on the wider Cardano community.

As BroClan is posed to be the first Multisig Wallet with DeFi capabilities in the Cardano ecosystem this proposal will help keep everyone using this software safe.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

I have developed a Multisig Wallet for Cardano that is already operational.

I have over 10 years experience in Linux operation and experience operating a high performance pool since the first days fd Cardano, deploying and maintain a high reliability service is trivial to me.

Additionally I have 2 years of JavaScript/Nodejs/MongoDB experience and given that the MVP of the product is already completed.

And I am now completing Catalyst proposal 100928 that will bring DeFi capabilities to Multisig wallets.

What are the key milestones you need to achieve in order to complete your project successfully?

1) Write an array of unit tests that covers close to 100% of all the usage possibilities

<u>Deliverable:</u> A library of tests and a GitHub process rejecting any change that will make the tests fail

<u>Tasks:</u> Integrate lucid simulator, Write unit tests that cover a large number of wallet types and all functions with all parameters for each wallet type, setup GitHub automations to ensure no changes can not be merged if the tests fail.

*<u>Timeline: </u>*1 Month

>Setup a bounty program

<u>Documentation:</u> bounty announcement containing the Bounty limits, and bounty claim process.

<u>Tasks:</u> Advertise Bounty program, review bounty claims, fix issues found in bounty claims.

<u>Deliverable:</u> End document detailing the bounties claimed and the steps took to fix the issues found

<u>Timeline:</u> 3 Months

>Upon completion of the prject BroClan must be live on mainnet with a high degree of assurance that users of the software are safe at all times.

Who is in the project team and what are their roles?

Leandros Holleman- Project manager, Developer and SysAdmin

I am a 1 man team and given the limited scope of the project I can handle it on my own.

Please provide a cost breakdown of the proposed work and resources.

[RESOURCES & VALUE FOR MONEY] Please provide a detailed budget breakdown of the proposed work and resources.

Answer:

Blockfrost 2 years = €600

SelfHosted Machine = €800

2 Yubi keys = €200

Dedicated laptop for accessing and managing the BroClan deployment: €200

1) Write an array of unit tests that covers close to 100% of all the usage possibilities

Effort Estimation: 160 Hours

2) Setup a bounty program

Effort Estimation 20 Hours

Bounties: 20000 ADA

Total:

180 Hours * €50 = €9000 ~ 26000 ADA

Bounties = 15000 ADA

Infrastructure = €1800 ~ 5200 ADA

46200 ADA

bounties not claimed will be returned to the treasury.

How does the cost of the project represent value for money for the Cardano ecosystem?

Cardano does not have currently a easy to use and high assurance multisig solution this is holding back institutional adoption, but also adoption by people that do not feel qualified to take full custody of their keys.

Multisig gives the user the ability to protect them self's from any danger including but not limited to keys stolen, keys destroyed, coercion or the key holder being incapacitated.

This could represent an enormous amount of liquidity that currently is unable to even consider entering our ecosystem.

And it will definitely offer a much safer experience to people already in the ecosystem.
