the rules?
A token can move today and still have controls that change what happens tomorrow. See who holds which powers—and what the evidence leaves open.

Free snapshot
Five controls worth understanding.
USDC was not paused when read. Its reviewed contracts still allow pausing, blacklisting, changes to minting privileges and code upgrades. These controls are not a finding of fraud or a guarantee of safety.
Pauser
Ordinary transfers can stop.
Can pause and unpause. Ordinary transfer and transferFrom calls require the token to be unpaused.
Blacklister
Address restrictions can change.
Can add or remove addresses from the blacklist. Transfer checks apply to relevant sender, recipient and caller addresses.
Master minter
Issuance privileges can change.
Can configure authorized minters and their allowances, or remove minters. Configuring requires the token to be unpaused. This does not establish unlimited minting by this role.
Proxy admin
The code can be replaced.
Can replace the implementation through upgradeTo. This is a separate role from the token owner.
Know the boundary
What this snapshot
doesn’t establish.
No safety score. No buy or sell simulation. Only the dated Ethereum USDC example above is covered.
- Who controls the role addresses, their custody arrangements, multisig thresholds or timelocks.
- Current authorized minters and allowances, or any selected address’s blacklist status.
- Every possible privilege, historical action or future change.
- Whether you personally can transfer or sell. No such transaction was performed.
Observed runtime bytes matched Sourcify’s on-chain records. Source correspondence relies on its match result and the reviewed verified-artifact source; recompiled metadata differed. Cedar did not compile the contracts. This is not a complete security audit or investment recommendation.

A transfer signature does not sign the product terms. This product, version and content hash are pinned by the client and bound by the server to the accepted proof. Payment and delivery are not atomic.

Recover an existing order
Use only a Cedar recovery file you previously saved. Paste its JSON below. This stays in this page until you explicitly retry that original order. Never paste a wallet recovery phrase or private key.
Loading creates no new signature and sends nothing. Retrying is a separate action. This page does not save recovery data automatically.
