Fast Transaction Confirmations:

This is beneficial for chains looking to integrate fast bridges for asset transfers, reducing risks in the process.

Icon

Low-Cost Data Availability

This is beneficial for applications needing strong data guarantees at a lower price point, which in turn enhances scalability

Icon

Certainty Across Chains

All chains using Espresso share the same Global Confirmation Network, providing certainty about the final state of transactions in real-time.

Robust Security

The confirmation guarantees offered by HotShot are comparable to Ethereum L1’s safety, where an adversary would need to control at least 1/3 of the stake to revert a transaction.

Confirmation Layer for L2/L3 Interoperability

Espresso provides fast confirmations (within ~5 seconds or as low as ~1 second on the devnet) for transactions across chains, significantly reducing reliance on L1 (Ethereum) finality.

Settlement via Espresso

After confirmation, only Espresso-confirmed blocks are eligible for settlement, ensuring integrity before the block is forwarded to L1 or L2 for settlement.
