Acta

The new infrastructure for digital trust.

“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 hours with API/SDK and templates.
  • Public state to reduce disputes and fraud.
  • Webhooks to automate lifecycle: issued/revoked/expired.

Common alternatives — and why we win

“Zero databases” — what we mean

You don't need to run a database for credentials. Acta manages encrypted storage and on-chain state; your app can be stateless (store only the credentialId).

How it works

1

Issuer emits credential

Issuer calls our API or use our dAppp. We canonicalize and hash the payload.

  • Template → VC JSON (no volatile fields).
  • Content Secure and protected against tampering.
  • 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"
  }
}
2

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"
}
3

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..." } }
}
