Decentralised data feeds are the most critical piece of infrastructure in DeFi — without them, on‑chain contracts are blind. Chainlink’s network of independent node operators and its quality‑of‑service metrics have made it the default oracle for major protocols. The cross‑chain interoperability protocol (CCIP) is expanding that role beyond price feeds to become a general‑purpose messaging layer. The real test is whether the node economics can sustain the network through bear markets. This vault examines that economic sustainability — it’s harder than it looks.
