Identity, signing, and governance — privacy-preserving by design

Verify identities. Sign documents with legal validity. Govern organizations on-chain. Treasury, compliance, and credentials — all integrated. Built on open standards with self-sovereign identity optionality. Zero-knowledge proofs. Selective disclosure. Your data stays yours.

Everything you need to operate at scale

Identity verification, document signing, treasury management, compliance tooling, and a credential wallet — integrated into a single platform.

KYC / KYB

Identity and business verification. Document AI, PEP/sanctions screening, UBO analysis. Approval workflows with risk scoring.

Document Signing

Multiple signing methods — Firma Digital, Web3 wallet, mobile passkey. Every method produces a verifiable, tamper-evident document.

Governance

Multisig vaults, org structure, cap tables, approval flows. Transparent, auditable, cryptographically enforced.

Treasury

USDC/EURC wallets, Circle integration, CCTP bridge, settlement batching. Org-scoped, fully audited.

Credential Wallet

Browser extension + dashboard. Store, present, and share verifiable credentials. Selective disclosure built in.

Compliance

Fraud detection, sanctions screening, circuit breakers. Velocity checks and impossible travel detection.

LEI Issuance & Maintenance Coming soon

Legal Entity Identifier issuance and annual maintenance. GLEIF-compliant, automated renewal, integrated with KYB verification.

Digital Currency Rails Coming soon

Stablecoin rails — USDC/EURC on-ramp, off-ramp, and minting. Cross-border settlement and fiat conversion. CRCD digital colón proof of concept for local currency tokenization.

Sign documents with legal validity

Multiple signing methods — from simple electronic to legally binding digital signatures. Every method produces a verifiable, tamper-evident document.

Firma Digital

PKCS#11 integration with Costa Rica's national PKI (BCCR/SINPE). Legal equivalence under Ley 8454.

Web3 Wallet

Sign with Solana wallet (Phantom, Backpack). Ed25519 signature anchored on-chain. Verifiable forever.

Mobile Passkey

FIDO2 WebAuthn signing from phone. Biometric-gated, device-bound. No passwords, no tokens.

PDF Attestation

Signed PDFs with embedded QR verification. Tamper-evident hash, blockchain anchor, human-readable proof.

Organization infrastructure on-chain

Corporate governance primitives — from cap tables to multisig vaults. Transparent, auditable, cryptographically enforced.

Multisig Vaults

Squads v4 on Solana. 2-of-3 or custom thresholds. Protect domains, assets, and signing keys. No single point of failure.

Org Structure

Departments, designations, branches. Role-based access control derived from on-chain membership. KYB-verified entities.

Cap Table

Ownership percentages, governance groups, voting thresholds. Transparent equity structure for DAOs and traditional orgs.

Approval Flows

Multi-step approval workflows with audit trail. Document signing, transfers, member changes — all gated by governance rules.

Domain Governance

SNS domain registration, subdomain delegation, and transfer protection via multisig vault custody.

Audit Logs

Every governance action logged with actor, timestamp, and cryptographic proof. Immutable. Exportable. Compliant.

Credential infrastructure as an API

Issue verifiable credentials, verify presentations, manage revocation, and enforce selective disclosure. One integration, any credential type.

Issue

Issue W3C Verifiable Credentials signed with Ed25519 or P-256. SD-JWT selective disclosure built in. Schema-validated, blockchain-anchored.

Verify

Verify credentials and presentations in real-time. Three-layer verification — institutional, registry, ledger. Any two of three sufficient.

Revoke

Revocation lists on-chain and off-chain. Status checks without contacting the issuer. Offline-capable verification.

Present

OpenID4VP presentations. Selective disclosure — verifiers see only what's needed. Zero-knowledge predicates for range proofs.

// Issue a verifiable credential
const credential = await attestto.issue({
  type: 'DrivingLicense',
  subject: 'did:web:citizen.example',
  claims: {
    category: 'B',
    issuedDate: '2026-04-02',
    expiresAt: '2031-04-02',
  },
  disclosure: 'selective',
  anchor: 'solana:mainnet',
});

// Verify a presentation
const result = await attestto.verify({
  presentation: vp,
  requiredType: 'DrivingLicense',
  checkRevocation: true,
});

Open specifications and conformance

Everything we build conforms to international standards. Every spec is public. Every implementation is open source.

Built on Attestto Open

Open digital public infrastructure. Sovereign, interoperable, privacy-preserving. No vendor lock-in.
