We are excited to enable support for privatization and private transacting of USDT, USDC and DAI! In celebration, we are introducing the Stablecoin Launch Event, a limited-time event that takes place for a period of two weeks starting from Thursday, June 29 (see more details and timelines below).

Calamari Network’s MantaPay app provides a secure and efficient platform for users to conduct private transfers. The goal of the Stablecoin Launch Event campaign is to encourage users to try out private transfers on our network and boost the Web3 privacy world, by bridging Web3 public assets into the privacy world to experience enhanced privacy.

For this campaign, we encourage our community users to experience a journey of bridging their stablecoins and then privatizing them to enjoy the Web3 world with Privacy!

Detailed rules about Privatize to Maximize Stablecoin Week

The Stablecoin Launch Event specially incentive program will also consist of two types of rewards. The total rewards will be 20,000,000 KMA.

Part 1: Gas fee paid rewards

Users who conduct privatized stable assets transactions using MantaPay will receive a stipend that covers a certain percentage of their gas fee paid. The incentive program will run for 2 weeks, with the total reward pool of 10,000,000 KMA. Reward breakdown for each week is as follows:

  • Week 1 ( June 29 to July 6): 5,000,000 KMA
  • Week 2 ( July 7 to July 14): 5,000,000 KMA

The rewards percentage will be determined based on the following multiplier scale:

  • If Multiplier = 0.0002X, the rewards will be 30000% of users’ gas fee paid
  • If Multiplier > 0.0002X, <= 0.1X, the rewards will be 1000% of users’ gas fee paid
  • If Multiplier > 0.1X, <= 0.2X, the rewards will be 300% of users’ gas fee paid
  • If Multiplier > 0.2X, <= 0.3X, the rewards will be 150% of users’ gas fee paid
  • If Multiplier > 0.3X, <= 0.4X, the rewards will be 133% of users’ gas fee paid
  • If Multiplier > 0.4X, <= 0.5X, the rewards will be 125% of users’ gas fee paid
  • If Multiplier > 0.5X, <= 0.6X, the rewards will be 120% of users’ gas fee paid
  • If Multiplier > 0.6X, <= 0.7X, the rewards will be 116% of users’ gas fee paid
  • If Multiplier > 0.7X, <= 0.8X, the rewards will be 114% of users’ gas fee paid
  • If Multiplier > 0.8X, <= 0.9X, the rewards will be 112% of users’ gas fee paid
  • If Multiplier > 0.9X, <= 1X, the rewards will be 100% of users’ gas fee paid

The single address transaction amount cap for Part 1 rewards will be set at 100. In this campaign, Addresses in Week 1 will be allowed to participate in Week 2.

Part 2: Score reward

In addition to the Part 1 rewards, we will also have the Manta Shield Score Reward, which is designed to further incentivize users to privatize their tokens and participate in the MantaPay ecosystem. The total reward pool will also be set at 10,000,000 KMA, split equally across the two-week program period.

For this section of the campaign, users will earn a score based on two factors:

  1. Gas fees paid — dollar value
  2. To private tokens’ dollar value

The formula for calculating a user’s score is:

UserScore = ([Gas Fees Paid] ^ 0.8) * ([To-Private Value] ^ 0.2)

At the end of each week, the top 100 users with the highest scores will be eligible to receive rewards.

The top 6 users will each receive 400,000 KMA each, and users ranked 7th through 100th will each receive 27659.5745 KMA.

Transaction category will be rewarded

You will be rewarded with a public to private transaction with privatizing your stablecoin from Manta XCM bridge.
