ekSign brings document signing back inside the bank. Customers sign in your own app or branded page — with the MFA they already use, and a signature that's cryptographically bound to the document so tampering is detectable forever.
Most banks sign through an external e-signature platform. That means a customer receives an email that is not from the bank, is redirected to another brand's portal, and verifies with that platform's own SMS OTP — an event with no link to their banking identity. The signed documents and the audit trail then live in the vendor's platform, where the bank is a tenant and pricing or availability changes affect access to its own records.
Experience
The journey leaves the bank
Another brand's email, domain and portal sit in the middle of a regulated banking action.
Identity
Signing is not tied to the customer
A vendor OTP proves access to an inbox or a phone number, not that your verified customer signed.
Custody & cost
The bank does not own the record
Audit trail held externally, priced per envelope. ekSign replaces that with a marginal cost per signing event on infrastructure the bank already runs.
Every signature is mathematically bound to the exact document and to a verified identity — so nothing about it can be faked, altered, or disputed later.
01
Tamper-evident by design
Alter one character after signing, and verification fails immediately.
02
Bound to a verified identity
The bank's existing MFA fires at the moment of signing, so the signature is tied to a real, verified customer.
03
Non-customers verified too
Guarantors and co-applicants sign using national digital ID — no bank account or new app required.
04
One complete audit record
Every signature, chained to the ones before it, held entirely on the bank's own systems.
01
A single customer
A push notification, a review inside the banking app, and one authentication step — the same MFA already used for transfers.
02
Multiple signatories
Loan agreements, joint accounts, and mandate changes often need more than one signature. ekSign supports signing in sequence, in parallel, or a mix of both — the bank's workflow decides the order.
03
Guarantors and other non-customers
A secure link sent from the bank's own domain, opened on a bank-branded page, verified with national digital ID — no bank account or app required.
