Cheddar Inbox converts real email activity — opens, replies, engagement signals — into cryptographic proof that powers blockchain verification and earns participants USDC rewards.
Cheddar Inbox uses real email engagement to generate heat — measurable proof of legitimate communication activity that powers our verification network.
Link your Gmail account with one click. Our system analyzes your inbox health — account age, message volume, engagement patterns — and assigns a quality score.
Your inbox participates in our engagement network automatically. Real email signals — opens, replies, interactions — create verifiable proof of legitimate communication activity.
Every verified engagement signal earns USDC rewards. Higher quality inboxes generate more heat and earn higher rates. Fully passive — connect once, earn continuously.
Email generates more verifiable human activity data than any other protocol. We harvest that signal and convert it into cryptographic proof.
Every email interaction produces measurable engagement signals — opens, replies, thread depth, response time. We call this "heat." More heat = more proof of legitimate activity.
Engagement signals are cryptographically hashed and anchored to the blockchain. This creates an immutable record of real email activity that can be independently verified.
Our proprietary scoring engine evaluates inbox health across 6 dimensions: account age, message volume, geographic signal, provider reputation, activity patterns, and network participation.
Participants across the globe contribute their inbox reputation to a distributed verification network. More nodes = stronger signal = better deliverability for the entire ecosystem.
Your inbox quality determines your earning potential. Higher quality = more heat = higher rewards.
Cheddar Inbox was built on a simple observation: email is the most underutilized source of verifiable human activity on the internet. Every day, billions of legitimate email interactions produce engagement signals that prove real human communication is happening — but that data goes uncaptured.
We built a system that harvests these signals — the opens, replies, and interactions that constitute real engagement — and converts them into cryptographic proof of work. This proof powers blockchain verification while rewarding participants with USDC for contributing their inbox reputation to the network.
The result is a new kind of infrastructure: a distributed network of real inboxes producing real engagement signals, creating real value. No mining rigs. No GPU farms. Just email doing what email has always done — connecting people — and finally getting rewarded for it.
