1  Alternate cryptocurrencies / Bounties (Altcoins) / 🎁🎁🎁 NimbusBSC Swap Contest is Live - 100,000 USDT Reward fund! 🎁🎁🎁 on: June 17, 2021, 12:38:47 PM

As a sign of gratitude to the immense support from our community, and to celebrate Nimbus's integration on Binance Smart Chain (BSC), we have decided to organize a Swap Contest on the Nimbus Swap on BSC. The Contest will last only for 14 days, and the total prize pool is 100,000 USDT.

The main beauty of the content is that ALL participating users will receive their proportionate rewards!

1) How to receive rewards?

In a nutshell, there are 2 participation models:

    1. Simply swap a minimum of 1,000 NBU (BEP-20) on Nimbus Swap.

    2. Swap a minimum of 2,500 NBU (BEP-20) on Nimbus Swap and then hold at least some of these NBU until the end of the contest.
The main difference is in the minimum amount that should be swapped and the consequent prize that the user will be eligible for. The more you swap and/or hold —the more rewards you receive!

Note that your total swap volume is calculated based on NBU/GNBU, NBU/BNB, GNBU/BNB, and NBU/BUSD pair swaps on the BSC network.


2) What’s the Reward fund?

The overall reward fund is 100,000 USDT worth of NBU (BEP-20).

However, this fund will be divided between the two participation models in the 40/60 ratio. This means, 40 000 USDT (in NBU) will be distributed proportionally between the participants of the first participation model and the remaining 60 000 USDT worth of NBU - between the second participation model participants.


3) How much time do you have?

You only have 14 days to swap as much as you can! Today, June 10, the contest has officially started and will run until June 24, 2021 (inclusive).


4) How will your reward be calculated?

    1. For the first participation model, here’s the calculation:
Your Reward = (Your total swap volume / Cumulative total swap volumes of all participants of the 1st participation model) * 1st participation model reward fund, i.e. 40,000 USDT worth of NBU

    2. Here’s the calculation for the second model:
Your Reward = [(Your total swap volume / Cumulative total swap volumes of all participants of the 2nd participation model) + (NBU token balance in your wallet at the end of the contest / Cumulative NBU token balances in the wallets of all 2nd participation model participants at the end of the contest)] / 2 * 2nd participation model reward fund, i.e 60,000 USDT worth of NBU


Important: your participation will count in only one of the two participation models and you can receive only one reward.

Your reward will be airdropped to your wallet in NBU (BEP-20) based on the exchange rate at Nimbus BSC Swap at the end of the contest. Also, please note that the airdrops will have a vesting period of 2 months followed by a gradual investing process of 20% per month. This helps protect the Nimbus community from the so-called “pumps and dumps”.

What are you waiting for? The Contest has already started! Go to Nimbus Swap, switch to BSC network, and start swapping NOW! 


P.S. Not sure how to switch to the BSC Swap of the Nimbus Platform? Simple! We have a brief guide for you here!
2  Alternate cryptocurrencies / Bounties (Altcoins) / 🔴🔴[BUG BOUNTY] Nimbus Bug Bounty Program. 50 000 NBU~50k$ 🔴🔴 on: March 30, 2021, 10:28:24 PM

We are thrilled to announce that the Nimbus Bug Bounty program is about to kick-off!

Those of you who find bugs in the Nimbus code before July 1 can receive Rewards from a Total Fund of 50,000 NBU! Find more detail below:


Our highest priority is the security and efficiency of all Nimbus solutions. That’s why we are offering an opportunity to our community members to submit your inputs for scaling the security of the platform.

But of course, we want to show our appreciation towards our bug hunters. So, we offer up to 50,000 NBU in rewards to up to 20 participants who succeed in this program.
Rewards



Rewards

Nimbus shall use the CVSS vulnerability scoring system to assess the severity of the bugs that you hunt. The reward fund shall be divided by threat level as specified below:

● Critical Threat level (CVSS 9.0–10.0)
✔Total fund of 30,000 NBU for this level to be split between a maximum of 5 winners
● Major Threat level (CVSS 7.0–8.9)
✔Total fund of 12,000 NBU for this level to be split between a maximum of 5 winners
● Medium Threat level (CVSS 4.0–6.9)
✔Total fund of 5,000 NBU for this level to be split between a maximum of 5 winners
● Low Threat level (CVSS 1.0–3.9)
✔Total fund of 3,000 NBU for this level to be split between a maximum of 5 winners


Please note that if there are no winners at some of the levels, the level’s reward fund will not be divided between other levels’ winners. Instead, it will remain unused.

On the other hand, if we receive more than 5 great applications within one level, we may provide an extra prize of up to 5,000 NBU for those who do not get rewards from the core reward fund outlined above.


Program Duration

The Bug Bounty shall begin on the 1st of April 2021 and is scheduled to end on the 1st of July 2021.

Winners shall be picked by July 12 and the rewards shall be airdropped in the winners’ wallets in the following days.

Areas of Interest

These are some of the bugs and vulnerabilities that we are especially interested in:
•Logic Errors
•Congestion and scalability
•Cryptography issues
•Missing access controls/unprotected or debugging interfaces
•Token manipulation
•Liquidity exploits


Out of Scope

•Attacks that the hunter has identified and exploited, leading to damages
•Attacks requiring access to leaked key and credentials
•Lack of liquidity
•Best practices, opinions and critiques
•Sybil attacks


The following activities shall result in disqualification:

•Phishing or social engineering attacks against the Nimbus users or team
•Testing with malicious or third-party systems or websites such as browser extensions, advertising networks, or SSO providers
•Denial of service attacks
•Automated or bot testing that generates heavy traffic
•Public disclosure of unamended or unpatched vulnerabilities


Terms

Only those vulnerabilities that are original should be awarded a bounty. Meaning in case of a duplicate report or two users reporting the same bug, the fastest user who submitted the report FIRST shall be awarded.
Public disclosure of the vulnerability, before the Nimbus team resolves it without explicit consent from the team, will make the bounty hunter ineligible for further participation.


Reporting a Vulnerability

Any vulnerability or bug discovered should be reported only to the Nimbus team at bugbounty@nimbusplatform.io. Bounty hunters should not disclose the vulnerability or the bug policy to another party before contacting the Nimbus team. Please ensure that you disclose the bug to the Nimbus team as soon as you discover it since speed matters!
In order to help us grasp the full context of the bug or vulnerability, we would appreciate it if you include as much information as possible in your mailers. Some of the topics that you can touch upon are:
● Steps needed to reproduce the bug.
● The potential impact of the vulnerability identified.


Overall, the more detailed is your vulnerability report, the higher your chances of receiving the rewards! So make sure to include as many details as you can.


Good look to all the participants!

Finally, we would like to wish all our community members the best of luck with this program. We are glad to have you on board, assisting in maintaining the well-being and prosperity of the Nimbus platform and all users.

As usual, if you have any questions regarding the Nimbus bug bounty program, please type your queries in the official Nimbus Telegram Chat.
