Polygon zkEVM Upgrade Cuts Prover Costs 73% as Type-1 Equivalence Unlocks Full Ethereum Tooling

Proofs got cheap, and builders noticed. Polygon pushed a major zkEVM release that shifts to Type-1 equivalence and a new prover pipeline, trimming proof cost by 73% per block. Gas to verify on L1 fell to roughly $0.003 per transaction at current batch sizes, and block time dropped to 2.5 seconds. The chain now runs the exact Ethereum opcode set, so devs can copy contracts, tools, and audits without edits.

Why cost fell
The team moved to a Plonky3-based recursion and a GPU-parallel witness build. Aggregating 1,024 transactions into one proof now uses 31% less compute, and hardware offload handles 92% of FFT work. Calldata compression and a smarter state diff cut L1 posting by 48%. In live runs, a full 5M gas block proved in 4.1 seconds on a single 8xA100 box, with fees to the user staying under a cent.

Adoption that followed
A top DEX ported its v3 contracts in one day and went live with $84 million TVL in 72 hours. Slippage on $1 million ETH/USDC trades hit 1.2 bps because routing stayed cheap. A large game studio moved its item mint to zkEVM and cleared 600,000 NFTs for $2,100 total, with users paying nothing thanks to sponsored gas. Lens moved a social graph mirror and cut write costs 89% while keeping posts on a DA layer. Paymasters now batch meta-tx at scale, so new wallets onboard with FaceID and zero seed phrases.

Market impact
MATIC saw $260 million in spot inflow as TVL rose $410 million on the week. Bridge net flows turned positive for the first time this quarter, adding $180 million. Perp funding stayed flat while spot led, showing real use, not leverage. L2 fee share shifted: zkEVM took 11% of all rollup fees from 3% before the upgrade, and sequencer revenue now covers prover spend with margin.

Trader and risk view
Type-1 equivalence removes the “almost-EVM” discount, so capital can treat the chain like a cheaper Ethereum block. That helps apps with thin margins: payments, games, social. Risk sits in two places. First, prover bugs. The code is now formally checked, yet a soundness flaw is still a tail event. Second, DA costs. If L1 blobs get busy, posting rises and the 1-cent user fee slips. The fix is in progress: a validium mode for apps that can trust a data committee.

The upgrade turns zkEVM into a general-purpose chain with Ethereum tools, Ethereum security, and near-zero fees. When proofs cost less than a packet of data, every app can be on chain. The next test is peak load. If the chain holds 10,000 TPS with stable costs, the “ZK endgame” stops being a slide and starts being a budget line.
