Current obstacles

Proof aggregation latencyCombining proofs from dozens of chains adds latency; batching and optimizations are ongoing.
Liquidity routingOptimal cross-chain routing requires sophisticated algorithms to minimize slippage and fees.

Physics limits

Interoperability is not atomicTrue atomic cross-chain transactions are impossible; AggLayer uses asynchronous message passing, which introduces settle-time delays.
Trust in validatorsAggLayer's security still depends on validator behavior and honest message passing; no on-chain solution can eliminate this.

How it works

3 parts

Liquidity pools

Aggregate tokens across chains

AggLayer pools liquidity from Polygon PoS, zkEVM, and CDK rollups, giving users instant access to tokens on any connected chain.

Cross-chain messaging

Send proofs between chains

Chains exchange zero-knowledge or optimistic proofs to confirm state changes, enabling trustless interoperability.

Unified staking

$POL secures the matrix

Validators can stake $POL to secure multiple chains simultaneously, amortizing security costs across the ecosystem.

About Polygon Labs

The team behind AggLayer

Polygon Labs

Ethereum scaling, AggLayer, Polygon PoS

Polygon Labs develops the Polygon ecosystem of Ethereum scaling solutions. Polygon PoS is a sidechain with 5,000+ TPS; AggLayer enables unified liquidity and cross-chain messaging across Polygon's rollups, validiums, and chains.

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.
