You've initiated a bank transfer, but the platform refused to credit it on FixedFloat. FixedFloat is a non-custodial swap service based in distributed (no single HQ), regulated under varies by user jurisdiction. Unlike traditional exchanges, FixedFloat can hold your funds during AML checks even though you never created an account. The service uses Crystal Blockchain for transaction screening. FixedFloat holds transactions when Crystal Blockchain flags source addresses with high risk scores, requiring source-of-funds proof before releasing funds. You send crypto to your deposit address, but it doesn't appear in your account. Or you initiate a bank transfer, and the platform refuses to credit it. You may receive a notification that the deposit is under review, or you may hear nothing at all.
FixedFloat holds transactions when Crystal Blockchain flags source addresses with high risk scores, requiring source-of-funds proof before releasing funds. FixedFloat suffered a major hack in 2024 that compromised their operations and eroded user trust. The hack also affected their compliance processes — they became more aggressive in holding transactions, partly to compensate for the hack losses and partly because their compliance infrastructure was disrupted. This background matters because it shapes how FixedFloat handles compliance — and how we approach resolving your case.
The compliance framework: FixedFloat operates under varies by user jurisdiction, overseen by unclear (no single jurisdiction). Their compliance infrastructure uses Crystal Blockchain for blockchain analytics and manual for identity verification. FixedFloat is known for fixed-rate and floating-rate crypto swaps, Lightning Network support, serving traders who want predictable swap rates and Lightning Network users — and their compliance team is calibrated to flag deviations from typical user behavior in that segment.
What triggers deposit rejected on FixedFloat:
Real case — post-hack paranoia: After the 2024 hack, a user's ongoing swap on FixedFloat was held indefinitely. FixedFloat's support — already disrupted by the hack — didn't respond for 3 weeks. The user's 1.2 BTC was stuck. We submitted a legal demand citing consumer protection obligations and the fact that holding user funds indefinitely without explanation constitutes conversion (unlawful detention of property). FixedFloat released the funds within 5 days of receiving the legal letter.
What FixedFloat requires to resolve this: Depending on the trigger, FixedFloat may ask for government-issued photo ID (verified through manual), proof of address (utility bill or bank statement within 3 months), crypto withdrawal blocks (exchange statements, bank records, payslips, tax returns, or business documents), detailed transaction explanations with on-chain evidence, and in some cases a video verification interview. The challenge: FixedFloat rarely tells you which specific trigger caused the deposit rejected, so you're guessing at what documentation to provide — and each rejected submission makes the next one harder.
Our approach is specific to FixedFloat: FixedFloat's post-hack compliance posture is defensive and uncommunicative. Their distributed structure (no clear HQ) makes regulatory escalation harder — there's no single regulator to complain to. We use legal pressure focused on the conversion claim (unlawful detention of property) rather than regulatory complaints. FixedFloat's lack of clear jurisdiction actually works in our favor — they can't invoke a specific regulatory framework to justify indefinite holding.
Deposit Rejected on FixedFloat — our strategy: We trace the deposit on-chain (for crypto) or through banking records (for fiat), identify why the platform flagged it, and prepare documentation that demonstrates the legitimate origin of the funds and clears the deposit for crediting.
The submission that matters: Instead of submitting through FixedFloat's standard support channels (where you'll get automated responses or generic template replies), we prepare a professional legal submission — a structured compliance package with a cover letter from a Swiss law firm citing unclear (no single jurisdiction) obligations and varies by user jurisdiction. FixedFloat's compliance team processes legal submissions differently from regular user tickets — they're assigned to senior compliance officers, not support agents, and they bypass the automated response loop that delays most cases by weeks.
Was this triggered by a hack or scam? If your FixedFloat account was frozen after unauthorized access, a phishing attack, or a SIM swap, the freeze may be a secondary consequence. Our crypto fraud recovery practice can trace stolen assets through on-chain analysis while we simultaneously work to unfreeze your account — the two processes are complementary, not sequential.
When standard compliance isn't enough: Some situations fall outside the normal compliance flow — inherited crypto holdings, accounts registered under another person's name, unprovable source of funds through conventional documentation, or cross-jurisdictional complications where your residence, the exchange's jurisdiction, and the fiat banking path all differ. If that sounds like your case, our complex cases practice handles scenarios that other firms decline.
Further reading: our guide on what to do when a crypto exchange freezes your account covers the documentation and legal strategy in more depth.
We trace the rejected deposit on-chain (for crypto) or through banking records (for fiat). Crypto deposits are rejected when {compliance_tool} flags the sending address; fiat deposits are rejected by banking partners.
For crypto: we prepare on-chain evidence showing the legitimate origin of the sending address, transaction history, and exchange records. For fiat: we prepare bank statements and transfer documentation.
We submit a formal appeal to {p_name}'s compliance team with a legal cover letter citing {aml_law}. Our appeal includes transaction tracing, source proof, and a narrative explaining the legitimate origin of the deposit.
Deposit credited to your {p_name} account — or returned to the source if {p_name} refuses. We advise on deposit patterns that trigger rejections and how to pre-clear large deposits.
The hack disrupted FixedFloat's operations, including their compliance and support teams. If your swap was held during or after the hack, response times are significantly longer than pre-hack. FixedFloat has not been transparent about the hack's full impact, which makes resolution harder. We use legal pressure (specifically, a demand for release of property) to force FixedFloat to process held transactions, regardless of their operational disruptions.
FixedFloat operates without a publicly disclosed headquarters, which creates regulatory ambiguity. This is both a problem and an advantage: there's no single regulator to complain to, but FixedFloat also can't invoke a specific regulatory framework to justify indefinite fund holding. We use general legal principles (conversion, unjust enrichment) rather than specific regulatory complaints.
Crypto deposits are screened by blockchain analytics before being credited. If the sending address has a high risk score — associated with mixers, darknet markets, sanctioned entities, or known scam addresses — the platform may hold or reject the deposit. Even if you bought the crypto legitimately on another exchange, the address history matters. We trace the chain and document the legitimate acquisition.
Fiat deposit rejections happen when: your bank's country is restricted, the sender name doesn't match your platform account, the payment reference includes suspicious text, or the banking partner flagged the transfer. Card deposits can be rejected by the card issuer's fraud detection system, not the platform itself. We identify whether the block is on the platform's side or the banking side.
For crypto: the funds may be held in the platform's wallet (not credited to your account) or returned to the sender address. For fiat: the bank transfer may be reversed and returned to your bank. In both cases, your funds aren't lost — but they're inaccessible. We help recover held deposits by providing the documentation needed to credit them.
