How To Transfer Tokens and Send Data Cross-Chain With Chainlink CCIP

on YouTube ↗28m

" summary

Chainlink CCIP moves test tokens and bytes between Ethereum Sepolia and Polygon Mumbai using Remix and MetaMask and examples actually complete end to end. The tutorial mints CCIP B&M tokens, funds a deployed contract, whitelists the destination chain, pays fees in LINK or native ETH, and shows a transfer 0.1 B&M that updates balances from 0.2 to 0.3. It also deploys messenger contracts on both chains, sends the string Hello World, and tracks progress in the CCIP Explorer.
