How l2beat tracks rollup state and risk stages
L2Beat is the authoritative public dashboard for rollup risk. It does not track price, it does not track hype. It tracks whether a rollup actually delivers what it promises: security, decentralization, and user control.
The dashboard classifies every rollup into one of three stages. Stage 0 means full training wheels. Stage 1 means limited training wheels. Stage 2 means no training wheels at all. Most major rollups sit in Stage 0 or Stage 1, and there is a reason for that.
What the stages mean
Stage 0 is where almost every rollup begins. The project runs its own sequencer, controls the upgrade keys, and if it wanted to take your money, it could. There is no functioning proof system that lets users exit without permission.
Stage 1 changes the math. A working fraud proof or validity proof system exists, and the upgrade mechanism requires a security council with multiple signers. At least one of those signers must be independent of the project. Users have an escape hatch - a way to force their assets out even if the sequencer stops cooperating.
Stage 2 is the finish line. The proof system is fully permissionless; anyone can submit a proof. Upgrades require a time lock of at least 30 days, and no security council can override the rules without giving users a month to leave. The project cannot freeze your funds or change the rules overnight.
The criteria in detail
L2Beat evaluates four dimensions. Proof systems come first: an optimistic rollup needs a fraud proof that anyone can submit, while a ZK rollup needs a validity proof that is actually verified on Ethereum. Without that, the rollup is just a database.
Upgradeability controls matter next. A multisig with five project insiders is better than a single key, a multisig that includes an independent party is better still, and a time lock before any upgrade takes effect is the gold standard.
Escape hatches are non-negotiable for significant value. If the sequencer stops producing blocks, can you get your money out? Some rollups have forced transaction mechanisms; some do not. L2Beat lists this clearly.
Sequencer decentralization is the fourth dimension. One sequencer means one point of failure. Shared sequencer sets or decentralized proposer networks reduce that risk, but most rollups still run a single sequencer.
Where major chains stand today
As of the data available, no major rollup has reached Stage 2. A handful have reached Stage 1: Arbitrum One is Stage 1. Optimism is Stage 0, zkSync Era is Stage 0, Starknet is Stage 0, Base is Stage 0, and Scroll is Stage 0.
Why so few at Stage 1? The criteria are hard. A working proof system that actually runs in production is expensive and complex, and a security council with real independence is hard to assemble. Most projects prioritize user growth over decentralization.
Stage 0 does not mean the project is a scam. It means the project retains the power to change the rules - that is a fact, not a judgment. For small amounts, Stage 0 may be acceptable; for significant assets, Stage 1 or Stage 2 is the safer choice.
How to Read the Dashboard
When you open L2Beat, look at the stage column first, then look at the risk summary for each category. A red indicator means the project controls the system, a green indicator means the user controls the system, and yellow means partial control.
Check the upgradeability section specifically. Who controls the upgrade keys? How many signers are required? Is there a time lock? These details matter more than the marketing copy on the project's website.
Check the exit mechanism. Can you withdraw without permission, and how long does it take? Some rollups allow instant withdrawals because the proof is submitted instantly; others require a seven-day challenge period.
L2Beat does not tell you which rollup to use - it tells you what risks each rollup carries. That distinction is the entire point. Evaluate the stage, evaluate your tolerance, and decide accordingly.
