This week Dave Isbitski, a veteran DevRel leader ( ex Microsoft, AWS, Amazon) explains how Chainlink has evolved from price feeds to a broader platform, with CCIP enabling secure cross-chain value/data transfers, compliance/privacy standards, and the Chainlink Runtime Environment (CRA) for workflow orchestration.

He walks through CCIP concepts—lanes, token pools (burn/mint, lock/mint), and risk management—and demonstrates deploying an ERC-20 on Avalanche Fuji, configuring a pool, and connecting to Arbitrum Sepolia for cross-chain transfers.
