 Asset interoperability allows tokens to move securely across the Superchain by burning tokens on the source chain and minting an equivalent amount on the destination chain. This approach addresses issues such as liquidity fragmentation and poor user experiences caused by asset wrapping or reliance on liquidity pools.
