ZKB Tokens
& NFTs

The ZK Cross Chain operates in an innovative way thanks to the following key attributes:

• (Fungible) Token ZKB using liquidity pools with a flexible deposit & claim approach and a limited hack risk compared to ZKB with minter roles
• ZKB support for ETH, BNB, MATIC, AVAX & FTM networks
• ZKB collections for NFTs
• Permissionless self-listings of (fungible) tokens
• Incentive for projects to use the ZK Cross Chain as they earn yield on the liquidity they provide themselves through fee-participation in the Liquidity Mining Pools.
• Incentives for community-sourced ZKB liquidity as everyone can earn part of the protocol incentive or ZKB fees from the Liquidity Mining Pools or for ZKB token holders, they can access the more attractive Reward Pools.
• Flexible and expandable concept to achieve decentralization right from the beginning
• Multi-Signature validation instead of using Key-Sharing wallet for the oracles
• Security-focused architecture that has been through internal and external audits

Crypto Projects or anyone can just provide the necessary liquidity on each of the connected chains for the ZKB to work properly. New tokens can be found by pasting the contract address in the search field on zkcross.org.

Here you find a step-by-step guide.

The ZK Cross Chain v2.3 currently supports token and NFT ZKBs between the following connected networks.

• Ethereum
• Binance BNB Smart Chain (BSC)
• Polygon
• Avalanche
• Fantom

We are aiming to expand this list quickly to include all other EVM compatible chains and will connect to almost every blockchain in the near future (with a focus on EVM-compatible chains first).

The ZKB token is a fair-launched utility token for the ZK Cross Chain. In the future, the ZKB token will get product-focused governance rights. Newly minted ZKB is emitted daily via the ZK Cross Chain USDT Farm.

Having farmed or bought ZKB entitles the holder to earn a share of 70% of the protocol incentive or token ZKB fees as rewards in one of the Rewards Pools.

Multiple burn mechanisms have been introduced that can cause ZKB to be deflationary depending on the amount of ZKB volume on the ZK Cross Chain. The buy-back & burn Protocol Incentive collects 15% of all ZKB fees which will be used to periodically burn ZKB. Additionally, ZKB is burned from every withdrawal from the Reward Pools.

The ZKB token is currently listed on

• Uniswap (Ethereum)
• PancakeSwap (BSC)
• SushiSwap (Polygon)
• TraderJoe (Avalanche)
• SpookySwap (Fantom)

ZKB Contract Address on Ethereum, BNB Smart Chain, Polygon & Fantom: 0x92868a5255c628da08f550a858a802f5351c5223

Most ZKBs work with a minter/burn functionality in which a token creator has to grant the ZKB a minter role of the token. The ZK Cross Chain uses Liquidity Pools to provide ZKB services, as this minimizes hack risks. The Liquidity Pools allow liquidity in any supported token to be added without the need to synchronize or partner with a project or even grant token minting permission to the ZKB contract.

The Smart Contracts have been extensively audited, both internally and externally (by Chainsulting and Haechi).
