yAgnostic Weekly Updates — Feb 16

We are pleased to bring to our dear community yAgnostic development progress report and other vital updates. Based on our roadmap for Q1 to Q2 2021, The team is currently working on a blockchain-agnostic solution for secure Vaults for defi strategies implementation. We are utilizing yEarn protocol as a reference. The solution includes Ethereum smart-contracts’ system, dApp for interaction with the protocol, governance token, secure bridge from Ethereum to Polkadot network for the token and basic solution on the Polkadot network. The system does not need KYC, does not keep users’ private keys and provides access for the user for each integrated blockchain.

To better understand the flow and the process of delivering the product, we’ve created roadmaps for both contracts and front-end implementation.

*Stages already passed and implemented are marked with (!)

Scope delivered

Below you can find the details on work done from contracts and the front-end side.

Contracts scope delivered:

• Implemented the functionality that allows to have several vaults with the same central token — that will allow to have several strategies for the same token in a future;
• Unit tests were corrected in align with new functionality;
• Testing strategy as a part of testing environment was developed to test all the functionality together;
• Started covering with Unit tests the functionality related to strategy (in controller, vault, and for interaction with earn and harvest modules);
• Finished migrations scripts and prepared test environment:
• Reworked private keys management
• Added all networks for migration
• Partly reworked migration settings
• Migrated test environment to the Rinkeby test net
• Verified all contracts on Etherscan
• Shared addresses and abi with the team
• Created draft protocol and contracts documentation for the command:
• Created how-tos for the main contracts interactions
• Created contracts interface description
• Operator script improvements:
• Added scripts for the sequences of actions: * strategist actions * bot actions * governance actions

Front-end scope delivered:

• Finished the refactoring of the dApp:
• Localization reworked: now all the signs are shown via i18next. It will allow us quickly and easily to add new languages to the dApp if required.
• Implemented Vaults page and began the connection of it with the yEarn contracts:
• Cloned the components of the page from yEarn and adjusted them to integrate into our dApp later
• Buttons and input fields for Deposit/Withdrawal were reworked and adjusted to ant.design forms (to easily manage and change them in future)
• Cloned the code accountable for deposit, depositAll, withdraw, and withdrawAll
• Got rid of all the redundant code parts and fixed minor bugs
• Prepared the code to be connected to our dApp
• Analyzed the state of the working app to proceed with creating a plan for investigation and implementation of its own version of the statistics.
