U.CASH Verify is the identity and holdings gateway for the U.CASH ecosystem. By cryptographically linking a verified email address to an Ethereum wallet and reading the on-chain UCASH token balance, it assigns each user a tier that other U.CASH services use to unlock perks, premium features, and access. Verification is non-custodial: the wallet stays in your control and only its public balance is queried. An optional U Account sign-in layers your centralized identity on top.
How it works
Wallet, email, tier
Sign in with Ethereum
Connect your web3 wallet through the browser. U.CASH Verify reads the connected account address on-chain; no private key ever leaves your wallet.
Read your UCASH balance
The on-chain UCASH ERC-20 contract is queried for the wallet's live balance and your uLevel is computed instantly.
Submit your email
Enter the email address you want linked to the wallet. A single-use verification token is generated and a confirmation email is sent via a transactional email service.
Confirm via secure link
Click the tokenized link in your inbox. The token is validated server-side and the email is marked verified against the wallet address.
Unlock your uLevel
Your verified email plus UCASH holdings resolve to one of six tiers, from User through Ultimate. Other U.CASH services query your status to unlock perks.
Optionally bind your account
Sign in with your U Account through portal SSO to surface your centralized identity alongside the wallet verification. The wallet flow works fully without it.
uLevel tiers
Six tiers by UCASH held
Your live balance maps to a tier, recomputed every time you sign in. Higher tiers unlock progressively richer perks across the ecosystem.

What U.CASH Verify can do
Six-tier uLevel system
Your UCASH balance maps to a tier, from User (1+) through Ultimate (1,000,000+), each unlocking progressively richer perks.
Email-to-wallet binding
A verified email is cryptographically tied to a wallet address through a tokenized confirmation flow, producing a reusable identity record other services trust.
Live on-chain balance read
The wallet's UCASH balance is read directly from the Ethereum contract via Ethers.js, so your tier always reflects real, current holdings rather than a stale snapshot.
Single-use verification tokens
Each verification mints a fresh 256-bit token that expires, preventing replay and ensuring the email owner is the one who clicked the link.
Public verification lookup
A REST endpoint lets authorized ecosystem services check whether an address has a verified email, enabling consistent perk gating across apps.
U.CASH SSO integration
An optional Sign in with U.CASH layer, signed through the portal with HMAC and surfaced via a whoami endpoint, adds centralized identity and account-status awareness.
Non-custodial by design
No funds are ever moved or held. Verify only reads public balance data and stores the email-to-address mapping, keeping full custody with the user.
How it fits in U.CASH
Verify and the rest of the network
Verify is the trust layer; other apps read verified status and uLevel to gate perks.
Pay - reads a wallet's verified status and uLevel to gate premium merchant features
Portal - acts as the SSO identity provider; Verify forwards the session via HMAC whoami
Agents - agent-facing services consult the record before granting elevated capabilities
Prime - a verified email and UCASH tier feed eligibility and reward calculations
Bounties - a verified wallet plus email binding reduces fraud and ensures payouts land right
FAQ
Questions, answered
What does U.CASH Verify actually check?
It reads your wallet's live UCASH token balance from the Ethereum contract and confirms you own the email address you submitted via a tokenized confirmation link. It does not access your private keys or move any funds.
What are the uLevel tiers?
There are six tiers based on UCASH holdings: User at 1 UCASH, Unifier at 100, Unleasher at 1,000, Unrelenter at 10,000, Utopian at 100,000, and Ultimate at 1,000,000. Your tier is recomputed from your live balance each time you sign in.
Do I need a U Account to use it?
No. The wallet-and-email verification flow works fully on its own. Signing in with your U Account is optional and adds your centralized identity and account status on top.
How is my email kept secure?
Each verification uses a single-use 256-bit token delivered through a transactional email service. The token is validated server-side when you click the link, and the link expires, so the binding cannot be replayed.
Can other U.CASH apps see my verification?
Yes. A public lookup endpoint lets authorized ecosystem services check whether an address has a verified email and, through the tier system, unlock perks and premium features accordingly.
