# Why Built on Layer 2?

1. **Scalability**: Layer 2 solutions have the potential to significantly boost transaction throughput and alleviate congestion on the main blockchain, allowing for a higher number of transactions to be processed per second.
2. **Reduced Transaction Costs**: L2 solutions often achieve lower transaction fees by processing transactions off-chain or on a separate chain. This cost-effectiveness benefits users who engage in transactions.
3. **Swift Confirmations**: Transactions conducted on Layer 2 can be confirmed much more rapidly than those on the main chain. This enables instant payments and enhances the overall user experience.
4. **Interoperability**: Many Layer 2 solutions are intentionally designed to be compatible with multiple L1 blockchains, facilitating cross-chain interoperability.
