Chainlink Integrations in Caér Finance

Caér Finance leverages industry-leading oracle infrastructure from Chainlink to enable secure, real-time, and trust-minimized cross-chain lending. Two core Chainlink services, CCIP (Cross-Chain Interoperability Protocol) and Data Streams form the foundation of Caér’s decentralized architecture.

1. Chainlink CCIP: Secure Cross-Chain Messaging

To support native cross-chain lending and borrowing, Caér integrates Chainlink CCIP, a generalized interoperability protocol that enables smart contracts on different chains to securely communicate and transfer data.

When a user deposits collateral on a source chain (e.g., Avalanche Fuji) and initiates a borrow on a destination chain (e.g., Arbitrum Sepolia), CCIP executes a burn-and-mint mechanism. The token is burned on the origin chain, and a CCIP Router relays a cryptographically verifiable message to the destination chain. Upon verification, equivalent value is minted or registered, enabling the borrow transaction without reliance on centralized bridges or wrapped assets.

2. Chainlink Data Streams: Real-Time Price Feeds

In addition to cross-chain messaging, Caér uses Chainlink Data Streams to power its real-time pricing and risk assessment infrastructure. Data Streams provide high-frequency, low-latency market data sourced from multiple institutional-grade providers and updated directly on-chain.

This integration enables Caér to:

• Monitor collateral valuation with sub-second latency

• Perform accurate borrowing limit calculations (e.g., LTV (Loan)

• Support collateral swap operations with live price validation

• Mitigate manipulation through multi-source aggregation

• Maintain transparency and determinism for all economic actions

By combining CCIP and Data Streams, Caér achieves a robust and composable infrastructure for permissionless lending across chains. The synergy of these technologies ensures users enjoy a seamless, secure, and real-time DeFi experienc without sacrificing decentralization, speed, or integrity.
