Sunny is a composable DeFi yield aggregator powered by Solana. The Sunny Protocol is designed with composability as a core feature, enabling other applications and protocols to easily build on top of it. One such composability mechanism is Sunny’s agTokens. The concept is similar to Yearn Finance’s yTokens. When a user deposits money into a Sunny pool, they receive agTokens that represent a pro-rata share of that pool which will grow over time.
