## How DeBank Bypass Works
DeBank actively monitors and bans IP addresses that perform bulk wallet queries. When your IP is flagged, DeBank returns fraudulent data (zero balances, fake token counts) or blocks requests entirely — a technique known as "API fraud."
**Crypto Checker bypasses DeBank fraud using proxy rotation:**
1. **Proxy Pool** — Load HTTP/SOCKS5 proxies from file or config
2. **Auto-Validation** — Proxies are tested and dead ones are removed automatically
3. **IP Rotation** — Each DeBank API request goes through a different proxy IP (round-robin or random)
4. **Fraud Detection** — Responses are validated; if DeBank returns suspicious data (zero balances for known-active addresses), the proxy is flagged and blacklisted
5. **Seamless Bypass** — DeBank sees each request as coming from a fresh, clean IP — no bans, no fraud, no fake data
The tool queries DeBank's API through rotating proxies, making it impossible for DeBank to correlate requests or flag your activity. Each wallet lookup appears as a unique, first-time visitor.
