Polyhedra Network 

ZKJ Price

What is Polyhedra Network (ZKJ)?

Polyhedra Network is a zero-knowledge proof (ZKP) infrastructure company whose products connect verifiable computation with AI workloads and cross-chain messaging. Its core products are zkBridge, a cross-chain interoperability protocol secured by ZK proofs, Expander, a GPU-accelerated proof-generation engine, and EXPchain, a blockchain for verifiable computation. The ZKJ token exists as an ERC-20 asset on Ethereum and a BEP-20 asset on BNB Smart Chain. DropsTab classifies Polyhedra Network under Zero Knowledge, with AI and Infrastructure category tags.

Why did the ZK ticker change to ZKJ?

Polyhedra Network renamed its ticker from ZK to ZKJ ("ZK Join") in late May 2024 after a trademark dispute with Matter Labs, the company behind zkSync. ZKJ and zkSync's ZK are separate assets from unrelated projects. The rename changed the ticker only — the token contract and the project stayed the same. Checking the ticker prevents confusion between Polyhedra Network's token and Matter Labs' ZK.

What is ZKJ's total supply and tokenomics?

ZKJ has a fixed maximum and total supply of 1,000,000,000 tokens. Per DropsTab vesting data, the largest allocations are Ecosystem and network incentives at 32% (320M tokens), private-sale token purchasers at 26% (260M), Foundation Reserves at 15% (150M), and Community, airdrop & other activities at 15% (150M). Core Contributors hold 10%. The five funding rounds carry no direct token allocation; the OKX Jumpstart sale covered 6M tokens, or 0.6% of supply.

How does ZKJ's token unlock schedule affect investors?

Polyhedra Network's vesting structure creates sustained monthly sell pressure from four parallel allocation streams. Per DropsTab vesting data, the TGE on March 19, 2024 released roughly 90.9M tokens across Community (55.95M), Foundation Reserves (19.95M), and Ecosystem incentives (15.008M) allocations. Monthly unlocks on the 19th follow across those streams plus Pre-TGE purchasers, totaling about 15.5M ZKJ per month in the first year. DropsTab tracks 210 scheduled unlocks. Private-sale, pre-TGE, and core-contributor allocations together represent roughly 38% of supply — a concentrated insider sell-side overhang.

Who backed Polyhedra Network and how much did it raise?

DropsTab fundraising data shows $45M raised across three disclosed rounds, within five total rounds. The Strategic Round in February 2023 raised $10M, co-led by YZi Labs (previously Binance Labs) and Polychain Capital. The pre-Series A in April 2023 raised $15M, led by Polychain. The March 2024 Funding Round raised $20M at a $1B valuation, again led by Polychain. An OKX Ventures investment (January 2024) remained undisclosed in amount, and an OKX Jumpstart sale of 6M tokens followed in March 2024.

What does Polyhedra Network's fundraising signal about maturity?

Polyhedra Network's backer lineup combines top-tier crypto venture capital with the sector's largest exchange groups. Polychain Capital appeared in three of five rounds and led two. YZi Labs, OKX Ventures, and KuCoin participated as exchange-affiliated backers — the same group of venues that later listed the token, which supported early distribution. The $1B valuation at the March 2024 round placed Polyhedra among the most highly valued zero-knowledge startups at that time. Exchange-affiliated backing cuts both ways: distribution reach comes with venue concentration.

Where can ZKJ be bought or traded?

ZKJ trades spot on more than 10 centralized exchanges per exchange data on DropsTab, including OKX, Gate, Bybit, MEXC, KuCoin, CoinEx, and Crypto.com Exchange. On-chain liquidity sits in two PancakeSwap v2 pools on BNB Chain (ZKJ/USDT and ZKJ/BNB), and tracked ZKJ liquidity is spot-only. ZKJ no longer trades on Binance spot, and third-party pages referencing Binance or HTX listings are outdated — current venue data is the reliable reference.

Why did ZKJ crash in June 2025?

ZKJ lost more than 80% of its value within hours on June 15, 2025, in a liquidity event rather than a disclosed protocol failure. The unwind involved withdrawal of Binance Alpha pool liquidity, large market-maker deposits onto exchanges, and cascading liquidations. Thin order-book depth around incentivized liquidity programs amplified the move. Polyhedra Network published a preliminary post-mortem on June 16, 2025. Order-book depth remained materially thinner than pre-crash levels afterward.

Can ZKJ be staked?

Staking is listed among ZKJ's token utilities in Polyhedra Network's documentation, alongside governance voting, payment of zkBridge and EXPchain fees, and proof-generation payments. Specific staking yields, lockup terms, and participation requirements are not publicly disclosed. ZKJ is a utility and governance token for Polyhedra's proof infrastructure — not a proof-of-stake network asset with a published validator reward schedule.

Is ZKJ a coin or a token?

ZKJ is a token, not a native coin. The asset exists as an ERC-20 token on Ethereum and a BEP-20 token on BNB Smart Chain, deployed at the same contract address (0xc71b5f631354be6853efe9c3ab6b9590f8302e81) on both chains — verifiable on Etherscan and BscScan. Polyhedra Network does not operate the base networks the token runs on; EXPchain, the company's own chain for verifiable computation, is separate infrastructure. "ZKJ coin" is a common search phrasing for the same token.
