Ethereum scaled. But it lost something. • Rollups made Ethereum faster, and fragmented everything that made it magical. Users split. Liquidity scattered. Contracts stopped talking to each other in the same block. • DeFi’s “money-Legos” broke apart. The seamless, atomic UX that defined Ethereum vanished into a maze of bridges and delays. • Compose (@ComposeNetwork) is how we put it back together. A composability layer that makes all Ethereum rollups act as one. • Built by SSV DAO (The team behind @ssv_network securing more than 14% of Ethereum validators and over $20B+ in TVL). Powered by ZK. Powered by Ethereum validators. Compose coordinates independent sequencers through a Shared Publisher, bringing near instant, atomic transactions across rollups. • Think of it as a conductor for Ethereum’s rollup orchestra. Each chain plays its part, but the melody stays in sync. • One click. Many chains. All or nothing. If one leg fails, everything reverts. Atomic by design. • For users: one UX across the entire rollup ecosystem. No wrapped assets. No bridge hops. Just Ethereum, everywhere. • For builders: deploy once, reach all rollups. Write one contract, access every chain. • For rollups: sovereignty preserved, liquidity shared. Keep your sequencer. • For validators: new revenue, new role. Publish cross-rollup bundles and route interop fees back to ETH. • ZK-powered proofs keep it trustless, fast, and final. Instant coordination. Aggregated settlement. Lower gas for everyone. • This is Ethereum, reassembled. One ecosystem. One experience. One standard for atomic composability. • Compose isn’t another L2. It’s the missing layer that makes every L2 feel like one chain again. How? • Built with a Based Shared Publisher architecture that syncs independent sequencers across L2s. • Each sequencer pre-loads inboxes/outboxes, simulates cross-chain calls, and runs a Two-Phase Commit (2PC). • If any leg fails, all legs revert. No stranded funds. No partial swaps. • ZK proofs secure every bundle and publish it back to Ethereum in the same block. • ERC-4337 compresses the entire flow into one UserOperation. One confirm. Many chains. • Validators act as neutral publishers, coordinating execution while rollups stay sovereign. • The result: Ethereum’s “money-Legos” are back instant, atomic, and validator-aligned. How does this stack up? • LP bridges rely on liquidity and trust. • Intent bridges depend on solvers and external markets. • Compose replaces both with programmatic guarantees: > No third-party solvency risk. > No wrapped asset confusion. > No waiting for finality. If one leg fails, nothing moves. That’s true atomicity and it’s what bridges were meant to be.
