1/ Ethereum scaled, but composability broke. Until now 🧵👇

2/ Bridges are slow. Rollups are siloed. UX is fragmented. @ComposeNetwork) changes that. It’s Ethereum’s new composability layer built on a Based architecture. Cross-rollup transactions become instant, atomic, and synchronous. Like everything’s on one chain again.

3/ So how is that even possible? It all starts with Ethereum’s validators, a $125B network that’s been underused until now. Compose presented the concept of Based Apps (bApps) that use Ethereum’s validator layer for coordination, not just block validation.

4/ @ssv_network validators is what makes it possible with a Based Shared Publisher It’s an implementation to solve for synchronous composability. Something that Ethereum was always meant to have. With the scaling effect of rollups, synchronous composability and atomic UX was compromised. Bridges help, but the question comes, are fast bridges the best UX possible?

5/ So what is this problem with the Ethereum ecosystem? Ethereum scaled with rollups, but then got siloed across users, dapps and liquidity. Ethereum lost its synchronous composable and atomic UX it was always meant to be.

6/ Compose Network is the first real Based App built by @ssv_network, powered by Ethereum validators. It uses a Shared Publisher to coordinate independent rollups and a Shared Bridge to move assets programmatically (no LPs, no wrapped tokens). Result: same-block finality, atomic UX, no middlemen, no 3rd party liquidity.

7/ Every cross-rollup action on Compose is all-or-nothing. If one leg fails, everything reverts. That’s how you get true synchronous execution. The kind of UX DeFi, gaming, and infra builders have been missing since rollups took o ff.

8/ It’s based (aligned with Ethereum validators), ZK-powered (for trustless coordination), and instant & atomic (one click → many rollups → all-or-nothing execution). Sequencers stay sovereign. Validators coordinate and publish. Users get the “money-legos (synchronous) ” UX back

9/ For builders and validators alike, Compose turns Ethereum’s validator set into the coordination layer for the entire rollup ecosystem. Builders ship once and reach every rollup. Users transact anywhere from anywhere. Validators earn more yield by powering inte rop.
