How is polygon's AggLayer v1 different from other multi-chains?
Long story short:
With AggLayer, X1 chain users holding $ETH can purchase NFTs on the Polygon zkEVM chain without having to cross-chain funds to the Polygon zkEVM chain first. From an end-user perspective, this feels like using a single chain; with AggLayer, users can interact with dApps without knowing they are accessing another chain.
Through AggLayer, users can also send assets to participate in activities on another chain. Assume that Zhang San is on a game chain built using Polygon CDK and connected to AggLayer. Zhang San’s wallet on the game chain also has ETH and DAI, and Zhang San wants to put them into the DEX on X1. Zhang San can create a transaction bridging $ETH and $MATIC and call the function of LP these tokens from the game chain (and pay all fees).
In AggLayer's final state, end users will be able to perform cross-chain atomic transactions in <span second.
