Build CRE workflows using Chainlink Privacy Capabilities

Talkat ETHGlobal Cannes 2026 · 2026-04-03..04-05· [web3, security]

Chainlink Runtime Environment runs off chain workflows written in TypeScript or Go that compiles TypeScript/Go to WebAssembly and executes them across the decentralized oracle network with consensus; a hello world fits ~28 lines. Triggers schedule or respond to HTTP or contract events and capabilities include on‑chain reads/writes, AI agent orchestration and Confidential HTTP requests that use enclaves plus a Vault Doll secret store. There are hackathon bounties: two CRE prizes of $2K, two privacy prizes of $1K and a Compliant Private Token Transfer option with an Access Control Engine for rules.
