Polygon unveils AggLayer: A solution to long-standing Ethereum Layer 2 challenges

• Polygon has proposed a blockchain protocol to boost interoperability and unify liquidity in the ecosystem. 
• The Aggregation Layer will connect Layer 2 chains while preserving their customizability. 
• MATIC could see a boost in adoption with Polygon’s unified bridge that will go live on mainnet in February. 

Ethereum ecosystem’s largest scaling solution, Polygon, announced a Aggregation Layer protocol. This new protocol targets the challenges faced by Layer 2 chains, some of which include fragmented liquidity and interoperability. 

Polygon’s Agg Layer mainnet will go live in February according to the project’s official announcement on X.

Polygon announces AggLayer to solve problems faced by Layer 2 chains

Polygon introduced a new thesis for blockchain design, a protocol that powers interoperability across Layer 2 chains, Aggregation Layer (AggLayer). The chains connected by the AggLayer will stand to benefit from unified liquidity across the Polygon ecosystem. 

Polygon developers explained how Ethereum developers' rollup-centric roadmap received the community’s response in the form of rollup frameworks, like Polygon’s CDK. These protocols offer a varied degree of customizability and compatibility with the Ethereum chain. 

While the approach offered a solution to Layer 2 chains’ need for independence, it fragmented liquidity, and users faced the issue of capital inefficiency and struggled with a bad user experience while bridging assets across chains. To tackle this challenge, Polygon’s AggLayer plans to introduce an environment to transact across different chains. The two major value propositions are:

• Sovereignty and scale of the modular framework of various chains. 
• Combining the liquidity and improving user experience of a single system. 

Any chain that chooses to connect to the AggLayer will seamlessly sync with a large network of aggregated blockchains in the Polygon ecosystem. This matters to users and MATIC holders as this will help users see all the chains as a single system, the interactions happen under a unified design interface presented to the user, likely to boost adoption and relevance of the protocol’s native token MATIC. 

AggLayer will see a mainnet release in February. MATIC price is $0.7832 at the time of writing, up 6.10% in the past week.
