To become a promoter, you just need to click on the "Vanity Name" link at the top of the page and pick a nickname for yourself, which will make you a member of the Advisory Board. In order to join the ranks, you need to pay 15 USDT, which will be donated to the community fund to reward developers and community members. Please note that only players who have registered with Vanity Name can enjoy promotion rewards. At VortexEngineDAO, we have an elaborate invitation system. To become a promoter, you just need to pick a nickname for yourself, which will make you a member of the Advisory Board. In order to join the ranks, you need to pay x USDT, which will be donated to the community fund to reward developers and community members. Please note that only players who have registered with Vanity Name can enjoy promotion rewards. After becoming an Advisory Board member, you can easily copy your promotion link, just click on the "Vanity & Referrals" tab. You can then share this link to friends or attract new players to participate in the Countdown Clash game through other channels. For those who join the game through your link and invest USDT, you will receive 10% of the amount they invest as a promotion reward. Even better, for those who buy or reinvest through your link, they will pay no extra fee, while you will still receive the promotion fee. In VortexEngineDAO, we store the promotion links used by players in a smart contract, which means that no matter which browser or device, as long as a player purchases through your link, you will receive promotion revenue. This ensures that you can accumulate considerable fragmented revenue over time. Even more exciting, VortexEngineDAO promotion is highly sticky. Once a player buys through your link, you will continue to receive promotional revenue from their purchases even if they use other people's links in the future. However, it should be noted that if a player has never used any promotion code to purchase CHIP, or has never used any promotion link, the corresponding promotion revenue will be distributed to VED holders as dividends. --- # Agent Instructions This documentation is published with GitBook.
