Fuel your chain
with Espresso

Open

Composable

Permissionless

Espresso is the protocol for coordinated block building: enabling & incentivizing chains to work together as one unified system.

About

Blockchains are the best platforms that humanity has for open, composable innovation.

Espresso keeps them that way.

Network

Chains and bridges that integrate with the Espresso Network receive fast, economically-secured preconfirmations. This enables more efficient cross-chain bridging.

The Espresso Network also underpins the Espresso Marketplace for coordinated block building: the only way to maintain composability across many chains.

Marketplace

Chains use the Espresso Marketplace to sell specialized block builders the right to order transactions for any given block. Block builders can bid to do so for multiple chains at once: offering developers the open, composable experience they want from a blockchain.

The Espresso Marketplace allows chains to coordinate, while safeguarding their sovereignty, scalability, and success.

Fast finality for users' transactions

More secure than centralized preconfirmations and faster than L1 finality...

These aren't your old preconfirmations. Finality on the Espresso Network enables a faster, more robust level of finality than you can get from chains today.

When our incentives align

Espresso is a protocol that not only enables chains to coordinate, but incentivizes them to do so.

Chains that integrate Espresso offer a better developer & user experience. They retain their sovereignty. And they create & capture revenue for their stakeholders that they would not otherwise.

Apps that work together like legos

Regardless of what chain the application is built on.

One of the big breakthroughs of blockchains lies in offering developers openly composable platforms. The rise of rollups, app chains, and beyond threatens to break that composability. Espresso fixes this. (No really, it does.)

We're building for:

App Developers

Stop sweating over where to deploy and get back to building.

Build a chain (or pick a chain) that uses Espresso to get composability with other apps and platforms, while also safeguarding your sovereignty, scalability, and sequencer revenue.

Fuel your Chain

Users

Choose chains, bridges, and apps that are fueled by Espresso for the open, interoperable experience you wanted from Web3 in the first place.

Infra

New lines of revenue: whether you are a block builder bidding in the Espresso Marketplace or a node operator securing the Espresso Network.

How Espresso Works

Capture Value

Chains sell the right to sequence transactions for their system, increasing the potential value they can capture for their ecosystems.

Stay Sovereign

Chains can opt in and out of the Espresso Marketplace for any given timeslot. Chains can also set a minimum price that must be met by the marketplace.

Fast Finality

The Espresso Network provides decentralized, economically-secured preconfirmations to chains, offering faster bridging experiences and beyond.
