Dual-standard capture
Every photo and video is sealed with a C2PA Content Credential (creator, time, GPS, device) embedded in the file plus an ERC-7053 record on the Numbers Mainnet — the same dual-standard backbone as ProofSnap.
Mobile App
Capture Cam Web3 camera for crypto-native creators
Capture Cam is the original Web3 blockchain camera from Numbers Protocol — iOS and Android. Every shot ships with cryptographic provenance (C2PA + ERC-7053), decentralised IPFS storage, and one-click NFT minting on Ethereum, Avalanche, and Numbers Mainnet. Built for crypto creators who want the full Web3 toolkit in one camera.
What is Capture Cam?
Capture Cam (originally launched as the Capture App in 2021) is Numbers Protocol's Web3 blockchain camera for iOS and Android. It embeds C2PA Content Credentials, registers each capture via ERC-7053 on the Numbers Mainnet, stores assets on IPFS, and lets creators mint NFTs in one tap on Ethereum, Avalanche, or Numbers Mainnet. It is the feature-rich sibling of ProofSnap, targeting crypto-native creators rather than newsroom workflows.
Capabilities
What you get
One-click NFT minting
Turn any capture into an NFT directly from the app on Ethereum, Avalanche, or Numbers Mainnet. No separate wallet flow, no gas-tank wrestling.
Decentralised storage
Originals are pinned to IPFS with redundant gateways. You own the storage; Capture Cam never holds custody.
x402 licensing built in
Every captured asset is automatically discoverable through Capture's x402 licensing layer — AI agents pay USDC per fetch, receipts settle on Base L2 in seconds.

Frequently asked
Capture Cam questions
How is Capture Cam different from ProofSnap?
Both apps come from Numbers Protocol and share the same C2PA + ERC-7053 secure backbone. Capture Cam is the original Web3-native camera (launched 2021) with NFT minting, multi-chain support, and decentralised IPFS storage — built for crypto creators. ProofSnap is the journalism-focused sibling app (iOS-only, launched 2026) — minimal UI, instant proof, no crypto skills required.
Is Capture Cam free?
Yes. Capture Cam is a free download on iOS and Android. On-chain registration and NFT minting use the network's native gas fees, paid directly from your wallet. Capture earns revenue when AI agents license your work through x402 — you keep the majority of every transaction.
Which blockchains does Capture Cam support for NFT minting?
Ethereum, Avalanche, and the Numbers Mainnet. The choice is per-capture from inside the app.
Does Capture Cam work without internet?
Yes. C2PA signing happens entirely on-device. ERC-7053 registration, IPFS pinning, NFT minting, and x402 endpoint creation are queued and submitted when you reconnect.
Is Capture Cam being replaced by ProofSnap?
No. Capture Cam continues as the Web3 flagship for crypto creators. ProofSnap is a new, focused product for newsrooms and frontline storytellers. The two share the same provenance backbone but target different audiences and remain actively maintained.
