Prom (PROM) closed at $5.988 on Phemex spot on 25 September 2026, 6.28 times its lowest close of $0.953 on 29 March 2026. The token pays for gas and carries the votes on Prom, a zero-knowledge layer 2 network built with Polygon CDK that runs Ethereum smart contracts unchanged and proves its transactions with zero-knowledge proofs.
That March close ended a fall of 91.6% from $11.333 on 16 September 2025, the highest close in the series. From the 30 June 2026 close of $1.099 the token then climbed 444.86%. The 25 September bar added 7.08% on the day and 18.01% on the week, yet PROM still closed 47.16% below that September 2025 peak.

What Is Prom and Where It Fits Among Blockchain Layers
Prom runs as a layer 2 on top of Ethereum. It executes transactions on its own chain and groups them into batches. It then posts a proof that the settlement layer can check, so balances lean on Ethereum's security without paying Ethereum gas on every transfer. If the stack of blockchain layers from layer 1 to layer 3 is new to you, Prom is a layer 2 in that picture.
The project's documentation calls its design EVM equivalence. Prom copies every Ethereum Virtual Machine opcode, which lets developers deploy existing Solidity or Vyper contracts without rewriting them. Wallets connect through the same JSON-RPC calls they already use on Ethereum. The proof system is the one explained in how ZK rollups fix Ethereum's inefficiencies. Each batch is proved valid up front, so the chain skips the week-long challenge window that optimistic rollups rely on.
The Prom zkEVM also supports ERC-4337 account abstraction, so an app can let its users pay fees in a token other than PROM.
For Prom crypto users the practical side is the bridge. The docs name Ethereum and Polygon among the chains on the official bridge, and they warn that some routes take more than an hour.
How Prom Uses Polygon CDK and Chain ID 227
Polygon CDK is the toolkit for launching zero-knowledge chains that come from Polygon, Ethereum's internet of blockchains, and Prom is one of the networks built with it. The welcome page of the docs compares PROM's role on its chain to the one MATIC played on the Polygon mainnet.
The Prom network connection guide lists chain ID 227 and PromScan as the block explorer. We queried the network's public RPC on 26 September 2026 and it answered with chain ID 227, matching the guide.
The docs are plain about who runs the machine. A single Trusted Sequencer collects signed transactions and decides their order, then closes a batch when it reaches 128K or hits a timeout. The Prover that turns those batches into proofs starts out centralised as well, and the protocol FAQ lists a decentralised sequencer and a market for provers as future plans. Forced batches are the escape hatch, since a user can place a transaction inside an Ethereum call that the sequencer has to include. That mechanism is what keeps withdrawals possible if the sequencer ever censors someone.
Finality comes in three steps. A transaction is final in the trusted state once the sequencer orders it and in the virtual state once its batch lands on Ethereum. Funds become withdrawable only in the verified state, after the contract accepts the prover's proof.
What the PROM Token Does
The PROM token is the gas currency on the Prom chain, and the docs also tie it to access to network services and to running your own node. It's the voting unit in Prom DAO as well.
Under the Prom DAO governance model, holders lock PROM in the governance portal and receive voting power that they assign to a delegate. Delegates and Validators share 32% of network fees, so the income attached to governance grows or shrinks with the gas the chain collects. Validators review proposals that pass the first vote, which puts a second check on upgrades to core contracts.
On Ethereum, PROM is the ERC-20 at contract 0xfc82bb4ba86045af6f327323a46e80412b91b27d. We read that contract over a public Ethereum RPC on 26 September 2026, and it reported a total supply of 20,000,000 PROM. Of that, 750,000 PROM sat at the 0x...dEaD burn address. The remaining 19.25 million match the maximum supply CoinGecko shows. CoinGecko counted 18.25 million PROM in circulation on 26 September 2026, and at the 25 September close that works out to a market value of about $109.3 million.
Most tokens attached to Ethereum layer 2 solutions earn their value the same way, as gas plus governance, so PROM's case rests on how much activity the chain draws. The docs pages we read publish no fee totals, and this page doesn't estimate that income.
How the Prom Price Fell 91.6% and Came Back
Phemex opened PROM/USDT spot trading on 13 January 2025, and the first daily close was $7.983. Eight months later the Prom price made its highest close of $11.333 on 16 September 2025. It then lost 91.6% over the next six months and bottomed at $0.953 on 29 March 2026.
The climb out started slowly and then sped up. PROM closed at $1.099 on 30 June 2026, still within sight of the low, and has gained 444.86% from that close to the 25 September anchor. The last 30 bars added 39.58% from $4.29 on 26 August, and the last seven added 18.01% from $5.074 on 18 September. On 25 September alone the token rose 7.08% from the prior close of $5.592.
The 50-day average crossed above the 200-day on 6 August 2026, a golden cross. By 25 September the SMA50 of 4.261 stood at a little more than twice the SMA200 of 2.115.
Method: every figure in this section is a daily close from Phemex's PROM/USDT spot series, 621 bars from the 13 January 2025 listing to 25 September 2026. The high and low are the maximum and minimum closes over that full series, divided into the anchor close. The averages are simple 50-bar and 200-bar means ending on 25 September, and the cross date is the last day the two changed order.
What Could Break the Prom Recovery
Spot turnover on the 25 September bar was $223,914 on Phemex. A 7.08% day on that much money moves the chart without saying much about how many buyers stand behind it. A thin book cuts both ways when holders who bought near $11 start selling into strength.
The chain's own design is the second risk. With one sequencer and one prover run centrally, an outage or a bad upgrade has no second operator to fall back on.
On Phemex, PROM has no live perpetual. Its perpetual is delisted, so exposure there runs through the PROM/USDT spot pair, and the $223,914 bar is the whole of that market's turnover on the anchor day.
The level that tells you the recovery is failing is the 50-day average. PROM closed 40.5% above the SMA50 of 4.261 on 25 September. A close back under that line would be its first since 2 July 2026, the last day the token finished below its own 50-day average.
Frequently Asked Questions
Why does the PROM contract say Prometeus?
The Ethereum contract's name field returns "Token Prometeus Network", which we read on 26 September 2026. CoinGecko's own id for the token is prometeus, the older name that the contract still carries.
When did the Prom chain produce its first block?
Block 1 on chain ID 227 carries a timestamp of 11:08 UTC on 29 October 2024, according to the network's public RPC queried on 26 September 2026.
What is PROM's all-time high?
CoinGecko records an intraday high of $105.94 on 29 April 2021, three and a half years before the zkEVM chain's first block. The 25 September 2026 close sits 94.3% below that print.
Can you trade PROM on Phemex?
Yes, as the PROM/USDT spot pair, listed at 10:00 UTC on 13 January 2025 with a minimum order value of 1 USDT.
Bottom Line
PROM has already returned six times its money from the March low, and it still needs another 89% to get back to the $11.333 close of September 2025. That second number is the one the chart can't answer on its own. The token's value is a claim on gas and fee share from a chain whose docs, in the pages we read, publish no fee figures and whose sequencer runs as a single centralised operator. If you trade the recovery, you're trading price momentum on a thin spot book, and the network's usage is the piece you'll have to find for yourself.
