The brief
- Polygon PoS: 8B transactions, $3T volume. Rio hardfork achieved 5,000 TPS.
- AggLayer connects 16+ chains for unified liquidity and cross-chain messaging via ZK proofs.
- Stablecoin volume: $79.25B as of May 2026, handling 53% of global USDC.
Technical approach
Sidechain with Ethereum security
Polygon PoS is a sidechain running Proof of Stake consensus. Validators stake $POL and earn transaction fees. Periodic checkpoints to Ethereum provide security.
Cross-chain liquidity aggregation
AggLayer pools liquidity across Polygon's rollups and sidechains, enabling instant cross-chain transfers and unified token economics.
16+ CDK chains with AggLayer connectivity
Teams deploy custom rollups via Polygon CDK. AggLayer gives unified liquidity and sub-5-second cross-chain settlement via ZK proofs.
