AirdropDistributor

pangea-core/contracts/distribution/AirdropDistributor.sol at main · pangea-protocol/pangea-coreGitHub

Overview

For the protocol that lists tokens for the first time and creates a liquidity pool, an incentive mechanism is needed to induce many users to supply liquidity to the initial pool. To meet this demand, Pangea's pool has a built-in airdrop function. Anyone can freely add airdrop rewards to the pool to add incentives for liquidity supply. The types of airdrop rewards that can be added to the pool are limited to the tokens constituting the pool, and liquidity providers receive airdrop rewards along with swap/flash loan fees.

If you deposit airdrop rewards in AirdropDistributor, the rewards will start to be distributed every Thursday at 09:00 (KST, UTC+9) and be distributed linearly for one week. During the reward distribution period, you can receive airdrop rewards in proportion to the amount of liquidity you supplied within the pool price range.
