Liquidity fragmentation
Liquidity fragmentation is the spreading of an asset's trading capital across many chains, pools and venues, so each market is thinner and prices worse.
The same token may trade on Ethereum, several layer 2s, Solana and a dozen exchanges, often in different wrapped or bridged versions. Each pool holds only part of the total liquidity, so a large trade in any one of them moves the price more than it would in a single deep market. Stablecoins split into native and bridged variants make the problem visible.
Fragmentation is a side effect of the multichain and rollup-centric roadmap and is one of the main complaints from users, market makers and developers. DEX aggregators, cross-chain intents, shared sequencers and chain abstraction all aim to reunite liquidity, or at least hide the split from users by routing across venues automatically.
Even when routing tools help, each extra hop adds bridge risk, fees and delays, and arbitrage between venues is never instant. Liquidity incentives on new chains can deepen the split by pulling capital away from established markets. For small tokens, fragmentation can mean no venue has enough depth to trade size safely.
Example
A trader wants to sell 2 million dollars of a token whose liquidity is split across five chains; no single pool can absorb it, so an aggregator routes slices through bridges and several DEXs.
