ACTA Logo Background

Acta

The new infrastructure for digital trust.

Try our Demo!
“Issue trust at the speed of light.”

Privacy by design

No PII on-chain; only hash + state. Data encrypted off-chain.

Deterministic proofs

JCS + SHA-256 → same content = same hash. Objective verification.

1-click verification

Embeddable widget + public portal. No extra integration to verify.

Verifiable by anyone

Provider-independent: public verification against the chain.

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/Panel using a template. We canonicalize and hash the payload.

  • Template → VC JSON (no volatile fields).
  • JCS canonicalization → SHA-256 = content_hash.
  • VC encrypted (AES-GCM) in Supabase Storage.
  • We return verify link + QR (capability token).
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"
  }
}

Hash anchored on Stellar

Only hash + status go on-chain via Soroban. No PII, no heavy data.

  • We publish {hash, statusRef} in Soroban contract.
  • Zero PII on-chain. Minimal costs and latency.
  • Indexer listens to events → caches state in DB.
  • We return txId and 'View on Stellar' link.
Sample
On-chain record (conceptual)
{
  "credentialId": "cred_24f9",
  "hash": "0xa3f8...e91",
  "status": "Active",
  "txId": "6b1d9a..."
}

Anyone verifies instantly

Portal & widget recompute hash server-side and compare with the chain.

  • We retrieve encrypted VC → decrypt on server.
  • Re-JCS + SHA-256 and compare with on-chain.
  • We show ✔/⚠/✖ and metadata (issuer, type, tx).
  • Embeddable widget + Verifier Portal (public).
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..." } }
}
