Blockzero Labs Vortex Testnet Competition

Details

The Vortex is at the center of the Blockzero Universe and allows XIO holders to earn yield generated in Vortex space exploration (such as funds from projects). This is achieved by staking tokens— such as XIO or XIO-LP tokens — into a selected portal that distributes rewards block by block. Users can harvest their accumulated rewards at any time (once a minimum threshold is met) from each portal staked into.

The goal of this competition is to ensure the functionalities of the Vortex are working as intended. By assessing the results from the Testnet contest, Vortex will be able to verify that:

• The dapp has no functional issues
• Vortex Portals can be created successfully
• Tokens can be deposited into the Vortex Portals
• Staking tokens can be staked to earn yields from the Portals
• Portal rewards can be claimed successfully
• Tokens move in and out of portals correctly

Future iterations of the dapp will be considered to improve/increase available features. As released to testnet, this dapp is the Minimum Viable Product (MVP).

The Vortex Testnet Competition will run for 7 days. It will start on Monday December 13th 5PM UTC and finish on Sunday December 19th 5PM UTC.

Register

To register for the competition:

• Visit #vortex channel (pinned messages) in Blockzero Labs Discord for registration instructions
• You must whitelist your Ethereum wallet address, and share your contact details: https://blockzero.typeform.com/to/gsrVmwHk

On successful registration, Blockzero Labs will deposit test tokens into your wallet by 10PM UTC each day (or the following day if you registered after 10PM).

You can enter the competition anytime up to December 18th 9PM UTC. Remember, entries will be reviewed and wallet addresses whitelisted / tokens deposited once per day by 10PM UTC.

Test Cases

A list of suggested test cases is below. Ensure you are connected to the Rinkeby network.

During testing, Blockzero Labs recommends you take screenshots of your inputs or take notes, for easy reference later, such as what distribution limits were applied at portal creation.

The Vortex dapp can be accessed here:

• Portal Create and Deposit
• Portal Stake and Claim

You will need some Rinkeby ETH in your wallet for gas to execute transactions (0.1 ETH should suffice). You can receive test ETH from the faucets below:

• https://faucets.chain.link/rinkeby
• https://www.rinkebyebye.com
• https://faucet.rinkeby.io (has been offline, unsure when it will restore)

Test Cases:

A. General testing of the dapp

• Successfully connect/disconnect wallet to the dapp
• Field inputs and buttons work as intended
• Data display correctly across the dapp (both static and dynamic)
• Mobile responsiveness of the dapp
• Social links work correctly

Notes:

1. After pressing the CREATE PORTAL / DEPOSIT / STAKE buttons for the first time, there will be at least 2 transactions to approve in the connected wallet — the first is to approve use of the token (one-time approval per portal), the second is to execute the relevant transaction (create / deposit / stake). This process duplicates for each reward token added per portal.
2. Ignore the test logos next to tokens, these will be corrected once the dapp is on mainnet.

B. Create new portals

• Successfully create a new portal with the relevant staking token and reward token/s
• Naming convention of the portal is generated correctly (see notes)
• Inserted token addresses are validated correctly, with the correct name (note, Rinkeby does not produce the token logo accurately, so this is out of scope)
• Minimum Reward Ratio and Distribution Limits are correctly set

Notes:

• Portal names are auto-generated with the naming convention: Portal [portalnumber] [Rewardtoken1] [Rewardtoken2]…
• Staking tokens are whitelisted and therefore only approved staking tokens will appear in the Staking Token drop-down — for the purposes on testnet, only XIO and XIO LP tokens will be whitelisted as staking tokens
• The Minimum Reward Ratio is the minimum reward per block, to ensure the reward per block doesn’t fall below this value / sufficient reward tokens are deposited. Example: if the minimum reward ratio is 1, you can add 100 tokens for 100 blocks but you cannot add 99 tokens for 100 blocks because it will fall below 1.
• The Stake Limit is the maximum stake amount the user can stake. Example: if the stake limit is 1000, the sum of all user stakes cannot exceed 1000 tokens.
• The Contract Limit is the maximum stake amount for the selected portal. Example: if the contract stake limit is 500, the maximum stakes among all users cannot exceed 500.
• The Distribution Limit specifies the quantity of staked tokens needed before rewards start accumulating for all stakers. Example: if the distribution limit is 300, rewards don’t start accumulating for stakers until a minimum of 300 tokens are staked.

C. Deposit tokens into portals

• View list of created portals
• Deposit tokens into the selected portal
• Successfully approve use of tokens (one-off approval for selected portal)
• Successfully create portal and view transaction in Dashboard

Notes:

• Refresh your browser if you do not immediately see a new portal you created appear in the portal list (it may take several minutes depending on network speed)

D. Stake XIO or XIO-LP tokens for portal rewards

• View list of available portals to stake into
• Select preset token quantities or input a manual quantity
• Successfully stake staking token into selected portal and view transaction in the Dashboard
• Successfully unstake selected stake in Dashboard

Notes:

• The APY data is not accurate and is still being worked on
• Refresh your browser if you do not immediately see newly created transactions in the Dashboard (it may take several minutes depending on network speed)

E. Claim portal rewards

• View list of portals staked into
• Claim rewards and view transactions in the Dashboard

Notes:

• Refresh your browser if you do not immediately see newly created transactions in the Dashboard (it may take several minutes depending on network speed)

Known bugs

As at the release of the testnet dapp, there is a known bug related to Unstakes which is actively being fixed:

• In the STAKE Dashboard, we have had to temporarily remove the Unstaked Date for any stakes already unstaked. This is because it appears in error in some cases (instead of showing “Staked Date”) and the backend data requires a fix.
• Related to above, the UNSTAKE button is temporarily enabled in all instances, even though it should dynamically be disabled where a stake is already unstaked. This means if you select a stake (which you may not realize is already unstaked), when you press UNSTAKE and try to confirm in MetaMask, it will throw an exception error, as that stake is likely to already be unstaked (you should be able to verify as the original deposit amount would have returned to your wallet in the original unstake transaction).

Note: You can only register once to the competition (single wallet, Twitter, email). We will only send test tokens to the first wallet registered. If we see testnet tokens being sent to unauthorized addresses except the addresses in this Medium article, those wallet addresses will be invalidated from rewards.

Preset Portals

There are 3 preset portals to test different configurations. You can also stake into these portals for testing.

1. Portal 0 XIO (staking token — XIO) — This portal has 5.5M XIO available as rewards to simulate the staking of XIO tokens
2. Portal 1 XIO (staking token — XIO) — This portal has 50,000 XIO available as rewards, to test what occurs when rewards run out (assuming enough stakers participate)
3. Portal 2 XIO (staking token — XIO) — This portal has 50,000 XIO available as rewards ending mid-way through testnet, to test what occurs during an shorter reward period and/or rewards run out (assuming enough stakers participate)
4. Portal 3 XIO (staking token — XIO-LP) — This portal has 2M XIO available as rewards to simulate the staking of UNI-V2 XIO/WETH (XIO-LP) tokens

2. Search for Frontend Bugs

There will be up to $2,000 XIO rewarded for any frontend bugs submitted and accepted during testnet. Frontend bugs are ones that render an expected functionality to be defective, and do not include cosmetic design issues or UX overflows.

Rewards will be split into the following tiers based on severity:

• Low severity $50 XIO
• Medium severity $100 XIO
• High severity $200 XIO

3. Search for Smart Contract Bugs

There will be up to $8,000 XIO rewarded for any smart contract bugs submitted and accepted during testnet.

The Vortex smart contract: https://github.com/BlockzeroLabs/vortex-contracts

The Vortex smart contract address: 0x94f46985a404F256efEeea1F5D92bB301dcb266e

Rewards will be split into the following tiers based on severity:

• Low severity $200 XIO
• Medium severity $800 XIO
• High severity $2,000 XIO

Known issues

There are currently known issues in the smart contract which will be resolved and therefore will not be accepted as bug submissions. These relate to:

• Portal addresses emitted as events in the smart contract that can cause higher gas
• Redundant functions relating to stakingToken, endBlock and totalStaked

Rules for all frontend and smart contract bug submissions:

You can submit as many bugs as you find but each bug must be submitted individually using this Typeform.

Only submitted bugs will be considered during testnet (Vortex will not review on-chain transactions). Feedback for optimizations/improvements will not be considered bugs.

Severity of submitted issues will be judged by the Council and all decisions are final.

Disclaimers

• Participants have until December 19th 5PM UTC to submit bugs.
• Bugs are rewarded on a first-come first-serve basis. This means, if two people submit the same bug, the person who submitted the Typeform first will be the only person eligible for compensation.
• Not all bugs will be treated the same or given the same compensation.
• Bugs discovered that would result in a loss of funds on the Protocol will be judged with higher Severity Scores.

Competition winners will be published in Discord and rewards will be distributed as soon as possible after results are final.
