Build with Stele.

Prove which terms each user accepted — or make your Solana program require them. Install a package, follow one guide, look things up in the references.

Stele Proof

Prove which terms each user accepted

1Publish your terms in the dashboard.
2Add the widget: the user signs the exact text, free.
3Check acceptances from your server or verify them on Solana.

<div
  data-stele-organization="acme.com"
  data-stele-document="terms-of-service"
></div>

<script src="https://stele.site/sdk/v1/stele.js" defer></script>

import { TermsAcceptance } from "@stelehq/sdk/react";

<TermsAcceptance
  apiBaseUrl="https://stele.site/api"
  appUrl="https://stele.site"
  organization="acme.com"
  document="terms-of-service"
/>

import { mount } from "@stelehq/sdk";

mount(document.querySelector("#terms"), {
  apiBaseUrl: "https://stele.site/api",
  appUrl: "https://stele.site",
  organization: "acme.com",
  document: "terms-of-service",
});

Proof guide — step by step

Stele Gate

Make your program require the current terms

1Create a policy: which document and version an action needs.
2Call require_current() in your Solana program.
3Wrap the action with gate() in your app: Accept & Continue.

// Cargo.toml: stele-gate = "1"
pub const POLICY: Pubkey = pubkey!("YOUR_POLICY_ADDRESS");

pub fn deposit(ctx: Context<Deposit>, amount: u64) -> Result<()> {
    stele_gate::require_current(
        &ctx.accounts.access_pass,
        &ctx.accounts.policy, // #[account(address = POLICY)]
        &ctx.accounts.user,
    )?;
    // … the protected action
    Ok(())
}

import { createSteleGate } from "@stelehq/sdk";

const stele = createSteleGate({ apiBaseUrl: "https://stele.site/api", wallet });

await stele.gate({
  policy: "YOUR_POLICY_ADDRESS",
  action: () => sendDepositTransaction(), // runs once the terms are accepted
});
