Know your code
hasn't been tampered with
Software supply chains are broken
The biggest breaches of the last few years weren't hackers breaking in. They were malicious code shipped through trusted pipelines.
SolarWinds
$18B+ damage
Malicious code injected into the build pipeline. 18,000+ organizations compromised, including US government agencies.
Codecov
Secrets exposed
A modified bash uploader script exfiltrated CI/CD secrets from thousands of repositories.
npm attacks
Millions affected
Typosquatting and account takeovers distributed cryptominers and credential stealers to millions.
How It Works
Three steps. Full trust.
Sign
Cryptographically sign your code with Ed25519 keys. SBOMs are generated automatically.
Store
Attestations are anchored to the blockchain — a tamper-proof, immutable record.
Verify
Anyone can verify any package against its blockchain attestation. Detect tampering instantly.
