Layer 2 Fee Arbitrage

Layer 2 fee arbitrage is the practice of exploiting price differences in transaction costs across various Layer 2 scaling solutions. As different rollups and sidechains have varying levels of congestion and fee structures, traders and protocols may shift activity to the most cost-effective chain.

This activity helps balance demand across the ecosystem but also highlights the fragmentation of liquidity. Arbitrageurs may also move assets between layers to capture price discrepancies in derivative instruments.

This practice is a natural consequence of a multi-chain environment. It requires efficient bridging infrastructure to be profitable.

Over time, as cross-layer communication improves, the scope for this type of arbitrage may change.
