True BTC returns should be based on three things simultaneously: sustainability, transparency, and resilience to extreme market conditions. It's not about how impressive the APY is or how vaguely the on-chain risks are described. This is why I've been paying increasing attention to @GOATRollup's ecosystem lately. It's not about piling on high-return terms, but about prioritizing Bitcoin principles and building a comprehensive risk management system first. First, correlation-aware capital usage. They put highly correlated assets like artBTC and BTC on the same LTV curve, using a unified pool for collateral/lending, instead of splitting it into numerous small pools that create liquidity fragmentation. The result is increased capital utilization without the system crashing due to erratic pricing models. Second, restraint in pricing encapsulated assets. The real pitfall of most cyclical strategies lies in the de-anchoring of encapsulated assets. Sumer uses contract pricing. For reserve-backed assets like artBTC and y-artBTC, the price is directly determined by on-chain reserves, not by external sentiment or hype. Simply put, the prices you see are backed by clear evidence of reserves. Third, it stands on GOAT's verifiable infrastructure. Running on the GOAT Network naturally brings transparent PoR, verifiable state transitions, and a coherent economic logic surrounding assets like GOATED/artGOATED. Lending caps, supply caps, and vetted listing mechanisms keep risks within a predictable range. I believe Sumer has done something very simple but difficult to achieve: using a complete set of engineering and constraints to prove that BTC returns can be both attractive and responsible. If the next round of BTCFi is to go further, Loop Responsibly will likely be more valuable than Loop Max.
