Liquidity Fragmentation

As decentralized finance continues to incorporate additional layer-1s and layer-2s, the market becomes increasingly fragmented. Since this is inherently undesirable, there are several potential solutions currently being tested by the market.

Some blockchains such as Polkadot and Cosmos tout their inter-blockchain communication credentials, but in reality, this interoperability is between layer-2s co-existing on the same layer-1 network. Inter-blockchain communication is significantly harder between layer-1s.

Alternatively, wrapped tokens such as Wrapped Bitcoin (WBTC) allow the trading of Bitcoin on the Ethereum network. Almost every major blockchain has some version of wrapped tokens.

There are also cross-chain bridges that seek to bridge one layer-1 chain to another. The complex problem of fragmentation has thus far created quite a complex picture of differing solutions.

However, these solutions face several key challenges:

1. Liquidity Dispersion: Cross-chain technology allows asset transfer between chains but doesn't resolve liquidity dispersion. The original chain's liquidity is still affected when assets move to a new chain, perpetuating liquidity fragmentation.

2. Bridge Security Issues: Cross-chain bridges are frequently targeted by hackers, resulting in significant asset losses. These security breaches erode user confidence and highlight the limitations of cross-chain technology in ensuring asset safety.

3. Poor Cross-chain Transaction Experience: Dispersed liquidity, lack of interoperability, and various cross-chain standards complicate on-chain transactions. Users face a complex process involving multiple cross-chain bridges and protocols to manage and trade multi-chain assets.

4. Asset Explosion and Ecosystem Diversification: The continuous influx of new assets and tokens in the expanding cryptocurrency market complicates liquidity management. Each ecosystem hosts numerous assets internally, but asset flow between ecosystems is limited by the development and adoption of cross-chain technology, leading to segmented market liquidity.

5. Value Capture by the Chain Layer: Current blockchain architectures often capture the value generated by decentralized applications (DApps) at the chain level rather than the DApp level. This limits DApp development and innovation. Exploring Layer 3 (L3) technology, which builds an application layer on existing chains, may provide DApps with better value capture mechanisms and flexibility but also increases liquidity complexity and challenges.

As the modular future unfolds, more specialized appchains and L2/L3 solutions will emerge, further intensifying liquidity fragmentation.
