The Starfish Topology is a swap that improves TVL-utilization and allows for onboarding new tokens without needing extra collateral. However, a Multi-Tier Starfish Topology (MTST) can further enhance this system by separating external tokens into four tiers and pairing them with different starfish tokens based on their volatility level. Tier 1 includes stable coins and native blockchain currencies like ETH, while Tier 4 consists of startups with high levels of volatility. The MTST aims to provide more stable and efficient trading opportunities for users.
