The new infrastructure
for digital trust
The simplest way to issue blockchain-based verifiable credentials. Encrypted, anchored on Stellar, and verifiable by anyone, with a zero-databases architecture.

Why ACTA
Common alternatives, and why we win
Most teams reach for tools that look like a shortcut and become a liability. Here is how ACTA compares on the things that matter.
Build in-house
Expensive, slow, and requires deep expertise to build DID, encryption, Vaults, on-chain anchoring, and public verification.
Ships the full stack: did:stellar, issuer API/SDK, encrypted Vault, Soroban anchoring, and instant on-chain verification.
PDFs / e-sign
Easy to forge, hard to verify, and no live status: no revocation, no updates.
Cryptographic credentials with live on-chain status and public, objective verification.
Web2 storage
Centralized servers hold unencrypted PII that's easy to breach, modify, or lose. If the company dies, your credential dies.
Encrypted Vaults on-chain. Even if ACTA disappears, your credentials remain verifiable forever thanks to Soroban.
VCs without anchoring
Rely entirely on the issuer's backend; no public proof of authenticity or revocation.
Anchored on Soroban for public, tamper-proof verification that never depends on the issuer.
“Zero databases architecture”
You don't need to store or manage credential data. ACTA keeps the encrypted payload on-chain and manages the full lifecycle on Soroban.
How it works
Three steps. Zero complexity.
Issuer emits credential
Issuer calls the API/SDK; ACTA encrypts the payload and anchors it on-chain.
- Canonical VC JSON
- Public on-chain anchor (Active / Revoked / Expired)
- We return a verify link + QR code
Credential anchored on Stellar
We publish the credential on the Stellar blockchain without sensitive PII.
- Selective disclosure
- Minimal costs and latency
- Issuing on Stellar made simple
Anyone verifies instantly
Our dApp reader verifies the credential against the Stellar blockchain.
- No account needed
- The holder decides which PII to disclose
- Shows status and metadata (issuer, type, tx)
For developers
Issue your first credential in minutes
Install the SDK, issue an encrypted credential anchored on Stellar, and let anyone verify it on-chain. No backend required.
