Contract blacklisting (Circle Blacklist)
The status is confirmed in the relevant contract. Further steps require establishing the basis for the restriction.

Diagnosis
One symptom.
Different causes.
The balance is visible, but the transfer fails. That alone does not explain who imposed a restriction or whom to contact.
Exchange restriction
Withdrawals are unavailable within the platform. Start with the support notice and case number; the cause may relate to an account review.
Check: the platform noticePrepare informationTechnical error
Insufficient fees or resources, the wrong network or another transaction failure may be involved. The error message and context are needed.

What Circle blacklisting restricts
In the USDC EVM architecture there are functions for checking status and managing blacklisting. Verify the contract and implementation used for the particular token.
A USDC restriction does not automatically block ETH and all other assets at the same address.
- 01
Identify the exact USDC token you hold
Check the network and contract against Circle's official list. Native USDC and a bridged token may require different checks.
- 02
Check status in the relevant contract
In the relevant EVM implementation, the
isBlacklistedfunction lets you check an address status. A failed request must not be interpreted as proof that no restriction exists. - 03
Establish the scope of the restriction
Token blacklisting differs from restricted exchange withdrawals and a technical transaction error. Each scenario has its own checks and enquiry recipient.
- 04
Prepare information for the assessment
Save the address, network, transaction hashes and notices. The documents needed and further steps depend on the restriction's basis and applicable requirements.

How we work
Unfreeze USDC:
from checks to an enquiry.
From analysing transactions and the source of funds to preparing documents and supporting your enquiry.
Initial assessment
We clarify where the restriction arose, review notices and define the scope of work.
Analysis and documents
We review transaction history and source-of-funds information, and help gather missing documents.
Preparing the enquiry
We identify the appropriate recipient and prepare the materials. If needed, we agree on a separate legal opinion.
Enquiry support
We agree on fees, preparation timelines and the scope of work, and help with correspondence within that scope.
Unfreezing USDC depends on the authorised party's decision. Preparation time and the external review period are different.
USDT AND USDC
A shared approach to checking.
Different contracts.
Both tokens require the network, address, transaction history and basis for the restriction. However, status checks and the authority to change that status must be verified for the particular issuer.

Questions and answers
Unfreeze USDC:
questions and answers.
Short answers about status checks, the tool's limits and possible next steps.
Does a transfer error mean Circle has blocked the address?
Not necessarily. First check the network, contract, funds for fees and actual address status. An application or exchange restriction may also have a different cause.
Can USDC be checked on any network?
The current tool on this site covers Ethereum ERC-20. Its result cannot automatically be applied to USDC on another network; verify the contract using Circle's official list. For a bridged version, first identify the contract and the responsible party.
Does Circle block the entire wallet, including ETH?
Blacklisting in the relevant USDC contract restricts operations with that token. It does not, by itself, change the ability to transact in ETH and all other tokens at the address.
If USDC is held on an exchange, should I contact Circle immediately?
First ask the exchange's support team why access is restricted. A withdrawal restriction within a platform does not prove Circle blacklisting; the review process may belong to the exchange itself.
Does the absence of blacklisting mean the funds are clean?
The result describes only the checked status in a particular contract at a particular time. It does not replace a source-of-funds assessment or rule out platform restrictions and other risks.
Does every enquiry require a Legal Opinion?
A universal requirement cannot be assumed. The documents needed depend on the request received, the restriction's basis and applicable law. The need for a legal opinion is assessed separately.
