Binance has named Boundless (ZKC)—a universal zero-knowledge (ZK) protocol aimed at internet-scale scalability—as the 39th project on its HODLer Airdrops page, confirming a distribution of 15,000,000 ZKC (1.5% of the genesis token supply) to eligible BNB participants. Spot trading for ZKC will open on September 15, 2025, at 14:00 UTC with pairs in USDT, USDC, BNB, FDUSD, and TRY.
Key points
- Airdrop size: 15,000,000 ZKC (1.50% of genesis supply).
- Eligibility window (retroactive): BNB subscribed to Simple Earn (Flexible/Locked) and/or On-Chain Yieldsfrom Sept. 2, 00:00 UTC to Sept. 5, 23:59 UTC qualifies for the airdrop.
- Listing: ZKC spot markets go live Sept. 15, 14:00 UTC; deposits opened Sept. 12, 12:00 UTC; Seed Tagapplied.
- Supply & circulation: Genesis supply: 1,000,000,000 ZKC; 200,937,056 ZKC (~20.09%) circulating upon listing; inflation starts at 7% YoY (Year 1) tapering to 3% from Year 8.
- Contracts: BNB Smart Chain 0x1524…e94a; Ethereum 0x0000…5555 (per Binance listing note).
What is Boundless (ZKC)?
Boundless is positioned as a universal ZK compute layer that lets independent prover nodes generate zero-knowledge proofs for L1s, rollups, apps, and infra across chains—decoupling compute from consensus so networks can scale without major architectural changes. The project describes its Mainnet Beta as live and frames ZKC as the incentive layer for verifiable compute.
How this HODLer Airdrop works
Binance’s HODLer Airdrops reward BNB holders based on historical snapshots of balances in Simple Earn and On-Chain Yields. For ZKC, snapshots from the Sept. 2–5 eligibility window will be used; tokens are credited at least one hour before spot trading begins. Users must complete KYC and be in an eligible jurisdiction.

Why it matters
Zero-knowledge infrastructure has become a core pillar for scaling and verifiable compute. A Binance HODLer Airdrop and multi-pair listing often jump-start token distribution and early liquidity, potentially accelerating developer and node-operator participation in the Boundless ecosystem. Project materials emphasize cross-chain applicability and “proof of verifiable work” concepts for rewarding useful compute.
