## Description

Solange Gueiros and Andrej Rakic present on creating cross-chain tokens using the CCT (Cross-Chain Token) standard with Chainlink’s CCIP (Cross-Chain Interoperability Protocol). They explain how oracles connect blockchains to external and cross-chain data, and how CCIP enables secure token and message transfers between blockchains. The CCT standard extends ERC20, allowing developers to make their own tokens interoperable across chains via token pools (burn/mint or lock/unlock mechanisms).

The speakers highlight the Chainlink Token Manager UI for easy deployment, as well as open-source smart contracts for advanced use cases. They introduce Chainlink Local, a local simulation tool for rapid development and testing, compatible with Foundry, Hardhat, and Remix. The session covers hackathon bounties, integration with other Chainlink services, and provides resources for developers. Q&A addresses use cases, integration with Anvil, and debugging support.
