Injective has integrated with Ethena Labs, allowing users to earn increased rewards for holding USDe in their Injective wallets. Users now receive a 7x multiplier on shards, up from the initial 5x, for holding USDe since March 11th. This enhancement followed the synthetic dollar's supply surpassing $900m. The campaign aims to reach a supply of $1 billion by April 1st, with adjustments including a reduction in the shard multiplier for Curve LP positions from 20x to 15x and for holding USDe outside of specific protocols. Additionally, Ethena Labs' USDe and sUSDe have been onboarded into Maker via Spark, potentially increasing lending APY for DAI holders due to sUSDe looping versus DAI. This development reflects the growing cooperative and competitive dynamics within the DeFi sector.
