The verified token for verified humans.
TrustPass (TPASS) is a Sybil-resistant ERC-20 that only Redbelly-KYC-verified wallets can mint — built entirely on Redbelly’s native identity infrastructure, not a centralized whitelist.
Sybil attacks are an economics problem, not a technical one
Any token, airdrop, or governance vote that treats “one wallet” as “one person” is exploitable — because making a new wallet costs nothing.
Bots mint everything
Airdrops, allowlists, and free mints get drained by scripts spinning up thousands of throwaway wallets in seconds.
One human, many wallets
Wallet addresses are free and infinite. Without an identity layer, "one wallet, one entry" means nothing.
Real users lose out
When Sybils capture the supply, genuine community members are priced out or simply never get a fair shot.
A reference implementation for Sybil-resistant tokens on Redbelly
TrustPass exists to show, end to end, how a real product wires Redbelly’s identity infrastructure into a standard ERC-20 — contract, frontend, and onboarding UX included.
Identity, not whitelists
Eligibility is verified on-chain against Redbelly's Eligibility SDK — no centralized spreadsheet of approved addresses to maintain or leak.
Enforced at the contract level
Every mint() call checks hasChainPermission() on-chain. There's no client-side check to bypass — the guarantee lives in the bytecode.
Education, not just gatekeeping
TrustPass Academy teaches newcomers what makes Redbelly different before they mint — verification with context, not just a checkbox.
Owner-configurable, not hardcoded
The eligibility registry and transfer gate are both adjustable by the contract owner post-deployment, without redeploying the token.

Why KYC matters here
TrustPass Academy is a bonus learning experience. Redbelly identity verification is the actual security boundary — it’s what makes minting expensive to fake at scale.
Verify once, reuse everywhere
Redbelly KYC issues a verifiable credential to your wallet. TrustPass — and any other Redbelly app — can check it without you re-uploading documents.
Your data stays yours
Verification uses zero-knowledge proofs. TrustPass's contract only ever learns a boolean — verified or not — never who you are.
It's the whole point of TrustPass
Without a real identity check, "Sybil-resistant" is just marketing. KYC is the mandatory security requirement TrustPass Academy explicitly does not replace.
Why we built on Redbelly
TrustPass needed a chain where identity isn’t an afterthought bolted on by a third-party provider — it’s part of the protocol.
Deterministic finality
BFT-based consensus gives fork-free, instant finality — transactions don't get reorganized away.
Parallel execution
Independent transactions process simultaneously instead of one-at-a-time, for real throughput.
Native identity layer
Receptor and the Eligibility SDK bring verifiable-credential identity checks to the protocol itself.
Built for real-world assets
Purpose-built for compliant tokenization — exactly the ground TrustPass's Sybil-resistance stands on.
Everything a Sybil-proof token needs
On-chain eligibility gate
Every mint checks hasChainPermission() against a configurable Redbelly registry.
Optional transfer gate
Owner can require both parties of a transfer to be verified, or leave transfers open.
TrustPass Academy
A 10-question, randomized quiz with explanations — education, not just gatekeeping.
Gas-optimized checks
The eligibility lookup costs under 8,000 gas — well inside the 50k budget.
Light & dark mode
A full theme system that remembers your preference and preserves Redbelly branding.
Built accessibly
Keyboard navigation, ARIA labels, reduced-motion support, and AA-contrast color choices.

Frequently asked questions
You need both: Redbelly KYC verification (the actual security requirement, enforced on-chain) and a passing TrustPass Academy score of 6/10 (an educational gate enforced by the app). The quiz never replaces KYC.
