“Issue trust at the speed of light.”

Privacy by design

One click verification

Verifiable by anyone

We are the simplest way to issue verifiable credentials.

For issuers (startups / platforms)

Build fast
  • Integrate in minutes with API/SDK and templates.
  • Public state to reduce disputes and fraud.
  • Tamper-proof lifecycle: verifiable state for every credential, publicly auditable.

Common alternatives — and why we win

“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

1

Issuer emits credential

Issuer calls the API/SDK; ACTA encrypts the payload and anchors it on-chain.

  • Canonical VC JSON.
  • Public on-chain anchor for verification (Active / Revoked / Expired)
  • We return verify link + QR code.
Sample
POST /v1/credentials
{
  "templateId": "tpl_escrow_completed_v1",
  "data": {
    "escrowId": "esc_7890",
    "network": "stellar-mainnet",
    "asset": "USDC",
    "amount": "500.00",
    "receiver": "GABC...RECEIVER",
    "roles": {
      "approver": "G...APP",
      "serviceProvider": "G...PROV",
      "releaseSigner": "G...SIG",
      "disputeResolver": "G...RES",
      "platform": "G...PLAT"
    },
    "releasedAt": "2025-08-15T16:30:10Z"
  }
}

Credential anchored on Stellar

We publish the credential on Stellar Blockchain without sensitive PII.

  • Selective disclosure
  • Minimal costs and latency.
  • We make issuing credentials on the Stellar blockchain simple.
Sample
On-chain record (conceptual)
{
  "id": "cred_3732",
  "issuer": "did:pkh:stellar:testnet:GCPZYT...",
  "subject": "did:example:ebfeb1f712e...",
  "status": "Active",
  "proof": "Ed25519Signature2020"
}

Anyone verifies instantly

Our dApp reader verifies the credential against the Stellar Blockchain.

  • No account needed
  • The holder desides wich PII to disclose.
  • We show ✔/⚠/✖ and metadata (issuer, type, tx).
Sample
GET /v1/verify/cred_24f9
{
  "verified": true,
  "status": "Active",
  "checks": { "hash_match": true, "onchain_status": "Active" },
  "summary": { "issuer": "Trustless Work", "type": "EscrowCompleted" },
  "proof": { "onchain": { "network": "stellar", "tx": "6b1d9a..." } }
}
