Astra Layer
Modular rollup infrastructure with fast finality and shared sequencing — from whitepaper to a mainnet 40+ teams build on.

Overview
Astra Labs came to us with a whitepaper and a deadline: a modular rollup with 2-second finality, shared sequencing, and tooling good enough for outside teams on day one.
Challenge
Every shortcut in sequencing and bridging becomes a security assumption. The team needed production-grade finality without a two-year research program.
Approach
We built on the OP Stack with custom sequencing and Rust services for batching and proofs, ran three public testnets, and wrote the runbooks alongside the code — not after it.
Solution
A rollup with shared sequencing, EVM equivalence, and a developer toolkit: local devnet, indexed APIs, and a bridge UI reviewed for clarity under real user testing.
Key features
- 2-second soft finality with shared sequencing
- EVM-equivalent execution and tooling
- Local devnet and faucet for builders
- Monitored bridge with pause controls
Results
Finality cut from 12s to 2s. Mainnet live with 40+ teams building, zero sequencer incidents in the first two quarters.
