Solana Devnet: test network. Documents and acceptances here are for testing, not production evidence.

Product overview

Stele keeps a record of what people agreed to that nobody can quietly change — and, for Solana applications, makes your program require it.

Two minutes, no wallet

The live demo shows both products with real transactions.

In plain words#

  1. A company publishes its terms. Stele writes a fingerprint of the exact text to Solana. From then on nobody — not even the company — can change what that version said.
  2. People accept them by signing with Face ID, a passkey or a wallet. It is free for them: no crypto, no fees.
  3. Anyone can check later what was accepted, against Solana, without Stele's servers or the company's database.

What the evidence does and does not depend on is spelled out in the trust model.

The problem#

Most "I agree" records are rows in a company's own database: a timestamp, a user ID and perhaps a document version number. Whoever controls the database controls the evidence. Terms can be edited after the fact, older versions quietly replaced, and records added or removed, and nobody outside the company can tell.

What Stele changes#

Typical clickwrapStele
The agreed textWhatever the company says it wasCommitted on-chain by a fingerprint when it was published; cannot be edited
Version historyEditableA hash-linked chain; versions cannot be removed or reordered
The acceptanceA database rowThe user's own passkey or wallet signature over a message naming the exact version
Replay and reuseRarely consideredSingle-use, time-limited, bound to one version, one network and one site
Who can verifyOnly the companyAnyone, with open-source tools and an archival Solana endpoint
If the vendor disappearsEvidence goes with itEvidence stays on Solana; receipts carry the text

What you get#

  • Dashboard to write documents, preview the exact bytes and fingerprint, publish versions with your wallet or multisig, manage roles, verify your domain, and see acceptances.
  • Acceptance on your own site with an embeddable widget: two lines of HTML, no wallet code. A hosted acceptance page is available too.
  • Signing without a wallet: visitors can use a passkey (Face ID, fingerprint, device PIN) that protects a signing key only they can unlock. Nobody needs SOL — fees are sponsored by Stele or by you.
  • Proofs beyond documents: purchases, refunds, consents and quote acceptances, confirmed by the customer and anchored on Solana with their details kept private.
  • Receipts for every acceptance, verifiable by anyone.
  • Verification in the browser, on the command line and in code. See Verification.
  • API, webhooks and SDK to link acceptances to your users and react to them on your servers. See the SDK & API reference.
  • Stele Gate (opt-in): policies, AccessPasses, require_current() for your Solana program, an Accept & Continue modal, and dashboard pages to integrate and test it. See Stele Gate.

Who it is for#

  • Companies that need to prove which terms a customer accepted, and when.
  • Platforms and marketplaces that collect acceptances at scale and want records that hold up under scrutiny.
  • Users, auditors and courts, who can check the evidence for themselves.
  • Solana applications whose actions must not happen without the current terms (Stele Gate).

What it is not#

  • Not an identity service. A signature proves control of a key, not who controls it. Link acceptances to your own signed-in users when you need to know which customer signed.
  • Not KYC or a compliance engine. Face ID unlocks a passkey on the device; it does not identify anyone to Stele. Gate enforces one rule — acceptance of a required version — not regulation.
  • Not legal advice. Stele makes the record verifiable; whether an agreement is enforceable depends on the applicable law.
  • Not a place for personal data. Published documents are public and permanent. Only public keys, hashes, timestamps and hostnames are written to Solana.
