Aave Makes Chainlink CCIP Its Default Cross-Chain Engine

Overview

• Aave has designated Chainlink’s Cross-Chain Interoperability Protocol (CCIP) as the default infrastructure for cross-chain activity across the Aave App and Stable Vaults.
• CCIP will carry deposits, withdrawals, vault rebalancing, yield‑optimization moves, asset transfers and cross‑chain governance instructions through one unified layer instead of separate systems.
• Stable Vaults will use CCIP to automatically move user deposits between networks such as Ethereum, Base and Arbitrum to chase fixed-rate stablecoin yield and remove the need for users to bridge assets manually.
• GHO transfers will follow token-specific rules on CCIP: a lock‑and‑mint model when moving from Ethereum to layer‑2s and a burn‑and‑mint model for other chain-to-chain moves to preserve total supply and fungibility.
• Aave says each CCIP bridge lane is backed by at least 16 independent node operators and rate limits to curb abnormal flows, and the decision comes as Chainlink expands its institutional work, signaling rising demand for interoperable stablecoin and settlement rails.
