The Polygon Aggregation layer (AggLayer) has tackled almost all the challenges of a siloed and interoperability-lacking blockchain environment. Now, with a unified, interconnected, and fully interoperable ecosystem, AggLayer provides a common layer for blockchains despite the differences in their consensus, use case, network effect, and adoption. Such an innovative concept of AggLayer provides a suitable ecosystem for innovative use cases that are driving unprecedented growth to Ethereum. Let’s dive deeper and understand all the possible use cases and real-world applications on AggLayer. 

AggLayer Use Cases and Real-world Implications 

Below is an in-depth analysis of Polygon AggLayer use cases that are driving the force behind Polygon and underlying Ethereum L1. Note that AggLayer’s top-most offerings; unified liquidity and cross-chain connectivity supports powerful and diverse use cases for DeFi. Hence, let’s first dive into DeFi use cases in a little more detailed manner:

1. DeFi

• Unified bridges- Bridges can integrate with AggLayer to become unified, connecting to Ethereum for seamless cross-chain transactions and transfer of native tokens. This means users on these bridges can access fungible tokens or assets from all the chains in the AggLayer ecosystem via a novel ZK-proof mechanism called pessimistic proofs. Unlike most bridges, AggLayer ensures that the influx & outflux of tokens remain fully under complete surveillance with zero interruptions from any third-party entities.
  
  A Perfect application of this can be the LxLy that uses AggLayer for:
  • Quick transfer of tokens- send USDC from Ethereum to any chain.
  • Send arbitrary & governance messages from PoS to any aggregated chain.
  • Trigger token contract with custom messages. 
  • Leverage bridgeAndcall () mechanism.
    
• Liquidity protocols/pools: AggLayer’s unified liquidity is of utmost benefit for liquidity protocols or pools. Through the unified bridge and pessimistic proofs, AggLayer allows users to pool their fungible and unwrapped assets from a chain to their preferred chain using the unified bridge to earn rewards. No complexity will arise due to wrapped assets and fragmented liquidity, which often comes with order books and pools.

• While there’s no solid application of liquidity pools with AggLayer atm, we can look at Movement Labs; the network with over $160M TVL. Movement has joined AggLayer mainly because of its full-fledged liquidity pools. It allows all the Move-Based L2 to benefit from AggLayer’s liquidity pools, boasting massive TVL from leading chains.
• Cross-chain Token swaps & exchanges: Token swaps powered by AggLayer allow users to leverage different technologies, such as atomic swaps and cross-chain AMMs, to facilitate swaps and asset exchanges across all the interconnected chains with an enhanced UX via the BridgeAndCall() method. 

• Payments & banking – AggLayer drives significant transformation to the payments and banking-related ecosystem by tackling key issues like lack of cross-chain access, liquidity fragmentation, and problems in data sharing. To understand the specific benefits, let’s look at its real-world application– Wirex Pay. The platform is using AggLayer’s 4 key innovations;
  
• Advanced staking mechanism: This ensures a refined staking process and transactions validation process while also heightening network security & overall integrity.

• Seamless asset transfers: Rapid and smooth asset transfers between different blockchains without causing the usual friction of cross-chain transactions.
  
• Cost reduction & speed: Agglayer optimizes operational costs for Wirex Pay while also speeding up transactions and offering benefits to both users and networks.
  
• Scalability and Flexibility: With AggLayer, Wirex Pay gets the flexibility needed to scale operations and expand its users and services with no disruption in the existing systems.

• Yield farming & staking platforms:  AggLayer enables the development of cross-chain staking and yield farming platforms that allow to;
• Diversify Investments: Stake assets in different chains to mitigate risk and enhance potential returns.
• Increase Liquidity: Access liquidity from various sources, enabling more efficient capital allocation. 
• Maximize Rewards: Take advantage of staking rewards across multiple protocols, leading to higher overall yields.

A good example of this is Lido– Ethereum’s leading staking platform, having a TVL of $25.26B. Lido is expanding liquidity on its network through AggLayer’s untapped liquidity of $1.4b approx. Also, Lido seeks to utilize this liquidity, unified interoperability, and the power of pessimistic proofs for its re-staking vaults building in collaboration with Mellow Fiance.

• Prediction markets- Polygon AggLayer enhances prediction markets by enabling cross-chain liquidity aggregation, allowing users to access deeper liquidity and better pricing across different blockchains. It reduces transaction costs by leveraging Polygon’s low-cost Layer-2 solutions, making markets more accessible. The AggLayer also enables seamless cross-chain participation, letting users place bets across multiple platforms, improving market efficiency. It enhances data flow and analytics, supports tokenized prediction markets using stablecoins, and facilitates cross-chain governance for decentralized market management. Overall, Polygon AggLayer boosts scalability, reduces friction, and fosters a more integrated, cost-effective, and dynamic prediction market ecosystem.

Polymarket can be a good example here. To ensure seamless operations and superiority on its platform, Polymarket taps into DeFi TVL, token inflow, and the daily active user base that AggLayer aggregates.

• Stablecoin platforms-  Polygon AggLayer ensures seamless functionality and efficiency on stablecoin platforms through an optimized, low-cost, and interoperable environment. Any Stablecoin integrated with AggLayer will benefit from inter-chain stablecoin transfers, liquidity aggregation, lower transaction costs, interoperability between different stablecoin & collateral platforms, plus a frictionless redemption every time.

Many Stablecoin-backed organizations and TradFi giants are building on Polygon to benefit from its AggLayer solutions. These include HSBC, IDA, and Evident Capital. Also, ambitious projects like mStable can connect to AggLayer to contribute its massive TVL with the chains in the AggLayer ecosystem.

Besides these mainstream DeFi use cases, there can be powerful AggLayer use cases in Insurance, DAOs, Wallet chains, Derivative exchange/trading platforms, and more.

2. Data: 

AggLayer bridges data gaps, allowing the data to flow seamlessly across different networks, hence providing infrastructure for the below novel data use cases:

Selective Data sharing- Different chains in the AggLayer ecosystem can voluntarily participate in data sharing between sovereign chains and ecosystems, similar to how LAN and WAN serve in traditional systems. This allows enterprises to build innovative use cases for data disclosure and specific audit rules.

Data markets- Similar to unified NFT and DeFi liquidity, AggLayer also presents promising opportunities for on-chain data markets. It allows users for better control and utilization of data despite the rapid growth of the aggregated chain ecosystem. 

Oracles– AggLayer offers a shared execution environment for oracles, enabling them to fetch and provide data to multiple chains without setting up separate systems for each chain. Hence, Oracles benefit from faster data propagation enabled through a single, unified interface created with AggLayer.
