Use Case
E-Signatures for Finance & Banking
Meet regulatory requirements with PAdES-LTA digital signatures, dual RFC 3161 timestamps, immutable WORM storage, and 5 independent verification anchors for every signed document.
Challenges financial institutions face
⚠ Regulatory compliance burden
SOX, SEC, Dodd-Frank, and state regulations require provable document integrity, timestamping, and retention. Generic e-signature logs rarely satisfy examiner scrutiny.
⚠ Fraud & non-repudiation risk
Loan applications, wire authorizations, and investment agreements are high-value targets. Without cryptographic proof of who signed and when, disputed signatures become costly legal battles.
⚠ Audit trail requirements
Financial regulators expect immutable, tamper-evident records. Simple event logs without hash chaining or external anchoring fail to demonstrate document integrity over multi-year retention periods.
How Abundera Sign supports financial workflows
✓ PAdES-LTA digital signatures
Every sealed PDF carries a PAdES-LTA digital signature with AATL-certified credentials. Green checkmark verification in Adobe Acrobat, the standard financial auditors expect.
✓ Dual RFC 3161 timestamps
Two independent trusted timestamp authorities (DigiCert + SwissSign) produce cryptographic proof of signing time. Compliant with eIDAS and accepted by financial regulators worldwide.
✓ 5 independent verification anchors
GitHub, GitLab, Sigstore Rekor, dual RFC 3161 TSA, and Bitcoin blockchain anchoring, all run in parallel. Even if one anchor is unavailable, the others provide independent proof.
✓ Immutable WORM storage
Signed documents are sealed in write-once storage with configurable retention (3 to 99 years). Once written, evidence packages cannot be modified or deleted.
✓ Access controls & identity verification
Access code gates, SMS OTP, government ID verification (Veriff), knowledge-based authentication (LexisNexis), and geography locking. Layer controls appropriate to transaction value and risk.
✓ API-first automation
REST API with 139 endpoints, webhook event notifications, and embedded signing. Integrate directly into loan origination systems, CRMs, and compliance platforms, no manual steps.
