Sending Cross Chain Messages

on YouTube ↗31m

" summary

LayerZero explains how its protocol delivers authenticated, immutable cross‑chain messages using immutable endpoints (non‑upgradable smart contracts) plus independent oracle+relayer pairs that provide block proofs and prevent spoofing. The demo shows a simple 50‑line Solidity app that sends a string, estimates native fees (destination gas plus oracle/relayer fee), and links contracts for burn‑on‑source mint‑on‑destination omnichain tokens. Support includes OP Stack networks like Optimism and Base, configurable security params, a testnet explorer, and permissionless endpoint deployment.
