Nepal's all-in-one digital signature platform.
Sign, seal and verify documents on any device — desktop, mobile or through your own systems. Built on the same EU DSS and ETSI standards used by Europe's national e-signing stacks, and made for recognition under the Electronic Transactions Act, 2063.
Every digital signature service, in one platform.
Whether you sign one document with a USB token or a million through an API, iSigner has a service for it.

Secure by design — only the hash leaves your server.
iSigner uses a deferred-signing model: the document stays server-side and only its hash travels to the signer's token or phone.
Prepare
The server computes the document hash and builds the signature placeholder — the file is never uploaded to the signer's device.
Sign
The signer approves with a USB token, Mobile-ID or biometric. The private key stays on the device; only the signature returns.
Seal & verify
iSigner embeds the signature, adds a trusted timestamp and revocation data, logs it to a transparency log, and issues a QR to verify.
Add signing with a few API calls.
A clean REST API, an OpenAPI 3.1 spec, signed webhooks and official SDKs. Prepare a signature, sign with any device channel, then embed and verify.
Pick the way you want to deploy.
From public-service use to fully self-hosted enterprise. Verifying a signed document is always free.
