Join the Chainlink Labs team to learn about the Chainlink Cross-Chain Interoperability Protocol (CCIP), understand why it's the industry's most secure cross-chain messaging protocol, and explore how it enables trust-minimized cross-chain smart contracts.

As part of this workshop, you will build, deploy, and interact with a smart contract across multiple blockchains, using CCIP to send tokens and messages cross-chain. You will also build a cross-chain tic-tac-toe game where you can play against someone on a completely different blockchain!

  • Web3 Wallet: You'll require a MetaMask or a similar Web3 wallet for this workshop.
  • Testnet Assets: Ensure your wallet has Sepolia testnet ETH and Avalanche Fuji testnet AVAX. These can be obtained from the Chainlink Faucet.
  • Network Addition: If the Avalanche Fuji network isn't added to your wallet, you can do so through Chainlist.


At least six months of prior programming experience and familiarity with Solidity or JavaScript
