Polygon 2026: Transition Progress from L2 to AggLayer
Polygon's core narrative in 2026 has shifted from "a single Layer 2 chain" to "an aggregation network (AggLayer) connecting heterogeneous chains," marking a new phase in its development trajectory. The transformation centers on dual upgrades in technology and tokenomics: the POL token has replaced MATIC as the multi-chain "hyperproductive" token supporting the entire AggLayer ecosystem. Meanwhile, AggLayer's technical boundaries have expanded to enable interoperability with chains of different architectures.

1. Technical Core: What is AggLayer?
Simply put, AggLayer is not a traditional cross-chain bridge but a shared settlement layer built on Ethereum. Its goal is to solve the liquidity fragmentation problem in multi-chain ecosystems, allowing different blockchains to work together as seamlessly as if they were a single chain.
Its technical feature ischain agnosticism, meaning it is no longer limited to connecting EVM (Ethereum Virtual Machine) compatible chains. In May 2026, Polygon-incubated privacy chain Miden, based on ZK technology, successfully achieved cross-chain settlement through AggLayer on its testnet, proving that AggLayer can connect blockchains with completely different architectures. This is significant for enterprise-grade payment and asset management scenarios requiring privacy.
Technical Highlight: AggLayer relies onzero-knowledge (ZK) proofsto verify cross-chain transactions rather than multi-signature committees, offering stronger security in mechanism. During a recent exploit incident involving $292 million in rsETH, AggLayer's architecture withstood the challenge without disruption.
2. Ecosystem Landscape: Who Has Already Joined AggLayer?
As of May 2026, AggLayer has attracted over 10 sovereign chains, covering several landmark areas:
Legacy Public Chain Ecosystem: Litecoin community's L2 networkLitVM, built on the Polygon CDK (Chain Development Kit), launched its testnet in Q1 2026, marking AggLayer's influence extending beyond the Ethereum community.
Institutional Asset Tokenization: Global asset management firm Apex Group has committed to tokenizing$100 billionin assets by June 2027 via T-REX Ledger built on Polygon CDK.
Payments and Stablecoin Settlement: Stripe enabled global USDC payments on Polygon in December 2025, serving merchants in over 150 countries. Additionally, tokenized funds such as BlackRock's BUIDL and Franklin Templeton's BENJI are already running on the chain.
3. Performance Upgrade: From Theory to Practice
To support real-world payment volumes, Polygon has significantly enhanced performance:
Block Gas Limit Increased to 160 Million: Boosting network throughput to5,000 transactions per second, on par with Visa's average daily processing capacity.
Ultra-Low Cost: After the February 2026 upgrade, each transaction costs approximately$0.002.
On the application level, Polygon's "Open Money Stack" has entered technical preview, aiming to provide financial institutions with an end-to-end stablecoin payment solution via a single API, further lowering integration barriers.

4. Strategic Adjustments and Current Status Snapshot
To focus on the AggLayer strategy, Polygon has made key trade-offs:
Founder Becomes CEO: Co-founder Sandeep Nailwal took the role of CEO of Polygon Foundation in March 2026 to drive strategy execution more decisively.
Strategic Focus: Polygon plans to phase out the zkEVM mainnet Beta in 2026, concentrating resources on the PoS chain and AggLayer.
Token Migration Completed: The migration from MATIC to POL is largely complete. POL's market cap currently stands at approximately $6.9 billion, ranking 16th in the cryptocurrency market.
What is the main difference between AggLayer and Superchain?
These are the two mainstream multi-chain solutions.Superchain (e.g., Optimism ecosystem) pursues standard uniformity, requiring all connected chains to adopt the same OP Stack technical framework; whileAggLayer pursues heterogeneous compatibility, aiming to connect chains of different technical architectures, regardless of EVM compatibility.
What is the special significance of Miden joining AggLayer?
Miden is the first non-EVM chain to join AggLayer. Its transactions generate zero-knowledge proofs on user devices, and its state model is "note-based" rather than "account-based," completely different from Ethereum. This proves that AggLayer's "chain-agnostic" vision is technically feasible, paving the way for more chains of different types to join in the future.
If I hold MATIC on the Polygon PoS chain, do I need to manually migrate?
If your MATIC is on the Polygon PoS chain, in most cases the tokenhas been automatically updated to POL. However, if you hold MATIC on Ethereum mainnet or other chains, you may need to perform a manual operation via the official migration contract. Always verify through official channels and beware of fake migration links.
