Polygon's AggLayer protocol aims to solve blockchain fragmentation by connecting multiple chains while preserving their sovereignty.​

Key features:

  • Unified liquidity across connected chains
  • Near-instant cross-chain transactions
  • No wrapped tokens needed
  • Compatible with any VM or tech stack

The protocol will launch in two phases:

  • v1 (February 2024): Unified bridge for participating chains
  • v2 (Later 2024): Asynchronous cross-chain transactions

AggLayer aggregates ZK proofs from connected chains and ensures atomic cross-chain transaction safety.​ Users can interact seamlessly across chains as if using a single network.​
