fswap.io presents itself as Fswap, a cryptocurrency exchange promising low fees and great rates on crypto and altcoin swaps. Its audience is people looking for a quick place to convert coins. PhishDestroy first flagged the domain on 2026-07-27 and placed it on our blocklist. As of 2026-10-19 the site was still online and serving content.
How the scam works
PhishDestroy has not yet assigned a specific scheme type, so there is no confirmed mechanism to describe. The risk comes from the format: an instant-swap exchange asks users to send coins first and trust the site to send back the converted asset. If the operator is not legitimate, funds sent to a deposit address are generally unrecoverable. Some sites of this kind also request extra payments or identity documents before releasing funds.
Evidence
Independent detection is limited. On VirusTotal, 4 of 89 engines flagged the domain as of 2026-09-14: alphaMountain.ai, Forcepoint ThreatSeeker, Gridinsoft and SOCRadar. That is a minority verdict, but it comes from several unrelated vendors. The domain also appears in 3 AlienVault OTX threat pulses, so other researchers have tracked it as well. PhishDestroy is the only blocklist known to carry it so far.
Infrastructure
The domain was registered through NameCheap, Inc. on 2024-05-13, more than two years before PhishDestroy flagged it. That gap points to a long-running site rather than a throwaway domain. It is hosted on the StormWall s.r.o. network in Germany. Its certificate comes from Let's Encrypt, which only confirms the connection is encrypted and says nothing about whether the operator can be trusted.
What to do
Do not send new deposits to fswap.io. If a swap you already started has stalled, do not pay any extra fee, tax or verification charge that is presented as the way to release your funds. Save transaction hashes, deposit addresses and any messages with the site, then report the loss to the exchange or wallet you sent from and to local authorities. If you uploaded ID documents, watch for identity misuse and targeted follow-up scams. Defenders should block the domain, check DNS and proxy logs for visits, and keep an eye on vendor verdicts as detection coverage grows.

“This is a coordinated "frozen order" exchange scam operated through a Telegram account named "Flowisland Support." The group poses as a cryptocurrency exchange service.
Method of operation: After a victim sends crypto for a swap (SOL to TRX), the operators claim the order is "frozen" due to a fabricated network error — e.g. a "7th validator error" on Solana, or a claimed amount mismatch (5.55 vs 5.56 SOL). No such error exists; this is a pretext.
They then demand the victim make a second ident”

After a phishing incident
Recomendações e orientações para as vítimas
Choose the steps that match what you shared. Keep a copy of this report alongside your own records.
O que devo fazer agora mesmo?
Urgente
Stop using the suspicious site. Open the real service through its official app or an address you already trust.
Alterar todas as senhas — e-mail, contas do Exchange, qualquer coisa que use a mesma senha
Ativar a autenticação de dois fatores usando um aplicativo autenticador (não por SMS). Desative a recuperação por SMS
Cartões de congelamento se você inseriu dados bancários no site de phishing
Que informações devo coletar para o meu relatório?
Diretrizes do FBI
Keep original emails, receipts, messages and screenshots in a secure place. A factual timeline helps the receiving authority understand what happened. IC3 evidence guidance ↗
Payment records — if you paid, save the receipt, amount, date, payment provider and recipient details.
Datas e horários exatos — de cada transação e do primeiro contato com o golpista
Capturas de tela — sites fraudulentos, mensagens de bate-papo, e-mails, transações em carteiras digitais, redes sociais
Todas as URLs e domínios utilizado pelo golpista (incluindo fswap.io)
Comunicações — e-mails, mensagens de texto, números de telefone e nomes de usuário que o golpista utilizou
Mesmo que você não tenha todos os detalhes — registre uma ocorrência mesmo assim. Mesmo informações parciais ainda ajudam nas investigações.
A quem devo denunciar o golpe?
FBI IC3 — Centro de Denúncias de Crimes na Internet (sistema federal de denúncias dos EUA)
Europol — Relatórios sobre crimes cibernéticos na Europa (UE)
Your bank or payment provider — contact its fraud team promptly through official contact details if money or card information was exposed.
Polícia local — cria um registro oficial, mesmo que não possam agir imediatamente
A report is not a guarantee of recovery or investigation, but prompt, accurate transaction data can help authorities and service providers trace the incident.
How do phishing scams typically work?
Sites falsos — clones idênticos, até o último pixel, de sites legítimos, com domínios ligeiramente alterados
Abate de suínos — confiança construída ao longo de semanas pelo Telegram, WhatsApp e aplicativos de namoro; em seguida, o dinheiro foi roubado
Golpes relacionados à recuperação — fraudsters pose as recovery agents and demand upfront fees. Never share a seed phrase or pay before independently verifying the provider
Golpes baseados em IA — deepfakes, phishing automatizado e sites gerados por IA, o que torna a fraude mais difícil de detectar
Como posso me proteger no futuro?
Adicione os sites oficiais aos favoritos — nunca clique em links de e-mails, mensagens diretas ou anúncios
Verificar domínios — verificar PhishDestroy antes de interagir. Verifique se o site usa HTTPS, a ortografia e a idade do domínio
"Bom demais para ser verdade" = golpe — retornos garantidos, endossos de celebridades, prazos urgentes
