The 4K Protocol Vision

4K Protocol is built with interoperability, decentralization, and composability in mind to support a growing ecosystem of collectors, marketplaces, dApps, and communities.


Guardians are nodes on the network that store physical assets and approve minting of physically-backed NFTs.

Physical Validators

Physical Validators are nodes on the network that coordinate authenticators and appraisers to determine authenticity and asset value.

Physical Oracles

Audit Oracles keep Guardians accountable by physically auditing the stored assets. Physical Asset Pricing Oracles provide a price feed to enable integrations with DeFi.


4K Protocol is a bridge that enables Physical NFTs to move across multiple L1s and L2s, even on non-EVM compatible blockchains.
