A rollup is only as quantum-safe as the chain it settles on. Starknet has now said it is actively considering cutting that tie.
If the idea moves forward, the real story is what Starknet would pay for the freedom.
I have read a lot of post-quantum roadmaps this year, and most share a quiet assumption: the chain controls its own schedule. Starknet doesn’t, at least not while it settles on Ethereum. That single fact explains why a short post from Starknet’s official X account sent STRK sharply higher within a day.
The Dependency That Sets Starknet’s Quantum Clock
Starknet is a validity rollup. It batches transactions, proves them with STARK proofs and posts the result to Ethereum. StarkWare’s own post on quantum readiness answers the obvious question directly: the verification layer is quantum-resistant, but the full stack is not yet. The proof system holds up because STARKs rely on hash functions rather than elliptic curves.
The same post admits the catch, though. Starknet inherits Ethereum’s security, so a weakness on Ethereum becomes a weakness for Starknet. Most of Ethereum’s stake sits in externally owned accounts, which are not quantum-resistant and would have to migrate.
As a result, Starknet’s post-quantum clock stays gated by Ethereum’s migration for as long as it settles there. The team can finish its own work years ahead and still wait on the base layer. Decoupling is meant to fix exactly that.
What Has Actually Been Floated
On October 8, Starknet said it was “actively considering becoming an L1,” in a post on its official X account. The statement added that the move would let Starknet become the first fully quantum-resistant network, with 2027 as the target.
Eli Ben-Sasson, a founder of StarkWare, framed the same idea in a separate post, and he posed it as a question: “good idea or bad idea?” He named two pressures behind it, the quantum threat and AI.
Still, nothing has been formalized. No governance proposal has been published, and any move would first need a community vote and a workable economic security model. I’d keep that distinction front and centre. This is a direction under consideration, not a roadmap item, and everything below depends on it going ahead.
Why Starknet Is Better Placed Than Most to Try
Starknet has real technical grounds for confidence. Native account abstraction turns every wallet into a smart contract, so a new account type can verify a post-quantum scheme such as Falcon-512 without a network hard fork. StarkWare also says Starknet v0.14.3 swapped Pedersen hashing for a BLAKE2s-256-based construction for OS program and configuration hashes on mainnet.
Even so, open work remains. Trie commitments and contract-address hashing are separate migration surfaces, and neither is done. Controlling the pace only helps if the team then uses it well.
Give-Up One: Ethereum’s Economic Security
This is the biggest cost. A rollup borrows the security of the chain beneath it. An independent Starknet would need its own consensus, its own validators and its own staked capital.
Bootstrapping that from scratch is hard for any network. STRK’s market cap is far smaller than ETH’s, so the economic security behind the chain would shrink to a fraction of what it enjoys today. Consequently, an attacker’s cost to overpower the network would rest on a much thinner stake.
Give-Up Two: Shared Liquidity and Ethereum’s DeFi Gravity
Right now, Starknet sits inside Ethereum’s liquidity pool. Leaving risks severing the trust connection with that capital. Lenders, market makers and large depositors treat Ethereum-settled assets as a known quantity, and a new Layer 1 would have to earn that trust all over again.
You can watch the current footprint on DefiLlama’s Starknet page, while L2BEAT tracks how rollups are secured. Those are the figures an independent Starknet would have to rebuild or replace.
Give-Up Three: Settlement and Bridging
Settlement on Ethereum is what makes Starknet’s finality credible to outsiders. Without it, Starknet would set its own finality, and every asset moving between the two chains would cross a bridge instead of a native settlement path.
Bridges have a poor record, since they rank among the weakest parts of crypto infrastructure. On top of that, an independent chain would carry its own data availability costs, which Starknet currently bundles into its Ethereum relationship. Each of these would become a new line on the budget.
Give-Up Four: Taking On Its Own Migration Debt
The last give-up is the subtlest. Today, Starknet can wait for Ethereum’s migration and share the burden. Once independent, it would own the entire upgrade: every account, every hash surface and every wallet still holding an old key.
Whoever controls the clock also does the work. If users and applications drag their feet, nobody else shares the blame for the delay. The migration debt would belong to Starknet alone.
Who Bears the Cost
The price move deserves a second look. TechFlow reported that STRK rose nearly 26% within 24 hours of the announcement, though other outlets put the gain anywhere from about 19% to about 40% depending on the window they measured. Treat the number as indicative. Reports also suggested derivatives drove much of the move, with futures open interest and volume running well ahead of spot activity. In other words, traders priced in the upside of independence within a day, while the costs will arrive far more slowly.
Nor would those costs fall evenly. Stakers and validators would carry the new security burden, and liquidity providers would face a smaller, less-tested market. Users, meanwhile, would deal with bridges and new custody habits. The team would get the speed it wants, and the ecosystem would pay for it.
My read is that the plan makes sense only if Starknet can show enough economic security, liquidity and trust to justify the break. For now it remains an idea, and a vote and a working security model have to come first. Follow the official updates at Starknet and StarkWare, and watch Starknet’s X account and Eli Ben-Sasson’s for any formal proposal.
