Project Scope

Smart Contract Development

A Solidity-based smart contract deployed on Kusama Hub
ZK enabled for private deposits & withdrawals
Compatibility with all Kusama Hub assets

User Interface

Browser-based, mobile-ready UI hosted on IPFS
Support for: Deposits, Withdrawals, Transfers, XCM Transfers
Compatible with popular ecosystem wallets (Nova Wallet, Talisman, Subwallet)

Anti-correlation Attack Mitigations:

Fixed deposit amounts (e.g. 1, 10, 100, 1000 units)
Batch payouts for withdrawals to multiple users
Interoperability
Ability to receive assets via XCM from any Kusama-connected parachain and transfer them to Kusama Hub for use in shielded pool.

Open-Source Delivery

All code (smart contracts and UI) published under the MIT license
Publicly accessible repositories
Project updates shared transparently via Polkassembly, Subsquare, or Polkadot Forum from Team with Milestone deliveries
Developer & User documentation

** re: Finder’s Fee: this payment is set aside to incentivize a broad search for the right implementor. Finder’s Fees are paid out at time of team engagement. Teams that submit themselves can collect their own Finder’s Fee at completion of project.

This project is about creating a smart contract and user interface for a private and secure platform on the Kusama Hub. The total prize money is $43,000, with an extra $2,000 for finding the right team to work on the project. The project will be supervised by Flipchan, Byte (Erin), and James Slusser.

The project timeline starts on March 17 and ends on July 31. The project includes smart contract development, user interface, anti-correlation attack mitigations, and open-source delivery. The smart contract will be based on Solidity, have private deposits and withdrawals, and be compatible with all Kusama Hub assets. The user interface will be browser-based, mobile-ready, and hosted on IPFS.

There are three milestones in the project:

Initial Pools & Basic UI: $16,200, 1 month
UI + XCM: $9,900, 1 month
Mainnet Deployment: $16,900, 1-1.5 months

The Finder's Fee of $2,000 is set aside to find the right team for the project. Teams that submit themselves can collect their own Finder's Fee at the completion of the project.
