Two core components
Marketplace + Protocol
4K consists of a marketplace and protocol that are designed to seamlessly on-ramp physical assets.
Meet our Physical NFT Marketplace
The 4K Marketplace is a decentralized Physical NFT exchange and aggregator. Discover and swap assets across chains using the full power of Web3.
Only 1% fee for sellers. Buyer pays gas. Far better than legacy Web2 platforms.
Built for Physical Assets
Seamless transactions for on-chain physical items. Buy and sell without managing an IRL inventory.
You own the items. Redeem your physically-backed NFT for the physical asset at any time.
Off-chain order books. On-chain settlements. No middleman.
The 4K Protocol Vision
The 4K Protocol is built with interoperability, decentralization, and composability in mind to support an ecosystem of people, projects, platforms, and communities.
Guardians are nodes on the network that store physical assets and approve minting of physically-backed NFTs.
Physical Validators are nodes on the network that coordinate authenticators and appraisers to determine authenticity and asset value.
Audit Oracles keep Guardians accountable by physically auditing the assets stored. Physical Asset Pricing Oracles provide a price feed to enable DeFi integrations.
The 4K Protocol is the bridge that enables physically-backed NFTs to move across multiple L1s and L2s without a working bridge. Even on non-EVM compatible blockchains.

The ability to connect the physical and on-chain worlds has long been one of the holy grails of blockchain. Though to date, attempts to bridge these worlds have been centralized, ad-hoc, and rife with misaligned incentives.
