Every FUDEX token is an ERC-3643 permissioned token. Unlike ordinary crypto tokens, it checks an on-chain identity registry before every transfer — so a regulated security can live on a public blockchain without breaking the rules.
Every whitelisted wallet is linked to a verified identity held off-chain. The contract consults this registry — not the wallet address alone — before allowing a transfer.
A transfer to a non-whitelisted wallet doesn't get "flagged" — it fails at the protocol level. Jurisdiction limits and suspensions are enforced the same way.
Only the transfer-agent wallet can mint or burn tokens, and recovery functions let the registrar restore holdings to a verified owner after wallet loss.
| ERC-20 (ordinary token) | ERC-3643 (FUDEX tokens) | |
|---|---|---|
| Who can hold it | Anyone with a wallet | Verified, whitelisted members only |
| Transfer checks | None — any address accepted | Identity registry checked on every transfer |
| Supply control | Varies by contract | Mint/burn by transfer-agent wallet only |
| Lost wallet | Assets gone | Recoverable via identity-verified process |
| Legal status | Usually none | Book-entry security on a master registry |
| Suits | Open crypto assets | Regulated, real-world securities |
Because the contract itself guarantees that every counterparty is verified and every supply change is registrar-authorized, FUDEX members can trade directly with each other — no intermediary needed at trade time. The compliance work happened up front, in the whitelist.
