According to TechFlow, on September 20, Sky (formerly Maker) co-founder Rune announced a proposal at the Solana Breakpoint conference, planning to introduce the Sky ecosystem into the Solana network and use Wormhole cross-chain bridging technology to achieve cross-chain of three tokens: SKY, USDS, and sUSDS. The core content of the proposal includes allocating 2 million SKY tokens per week as incentives to Solana DeFi protocols that integrate USDS and SKY.
