According to official news from ChainCatcher, Doubler, an on-chain yield protocol based on the Martingale strategy, has joined the Manta Network ecosystem and launched a new round of Liquidity Airdrop. Users can participate in Doubler through the Manta Pacific network and obtain DBR airdrops with a maximum of 10% of the total token volume.

Doubler provides users with a low-threshold on-chain Martingale trading strategy. Users only need to deposit ETH. The Martingale strategy will attract new users to cover their positions when prices fall, lower the average price of all users' positions, and generate income when prices rebound.
