DEX-Dumps · flashcrash detection

20–40% windows when
DEX dumps before CEX reacts.

When a token tanks on-chain after a rug, hack or liquidity event — DEX adjusts in seconds, CEX takes 5–15 minutes. The gap is real, executable, and big. Buy on DEX, short on CEX perp, hold until CEX catches up.

Case study

SFUND −99.3% on DEX,
spread up to 8,726%.

A textbook flashcrash signal: SFUND tanked 99.3% on DEX in minutes. The token was simultaneously trading on multiple CEX where the price hadn't adjusted yet — the spread between DEX and CEX hit 8,726% at the depth of the dump.

Within 3 minutes, the on-chain price recovered nearly 2,200% from the bottom — and that's the window that matters. Not every dump signal turns into 8,726% — but most live long enough to capture 10–40% at scale.

The signal arrived in our DEX-Dump channel at the start of the move. Subscribers had the route, the open networks, the cheapest perp leg, and the funding rate — all in one Telegram message.

How it works

From on-chain dump to your alert in seconds.

01 / DETECT

Track DEX prices

DexScreener stream, OKX-DEX HTML, MEXC-DEX hybrid. Every pool above $50k liquidity is monitored. Price changes over 5M / 1H / 6H / 24H windows feed the dump detector.

02 / FLAG

Threshold + heuristics

Sharp 5M drops with 1H confirmation flag a dump. Anti-fake-dump heuristic checks pool depth, volume profile, and CMC flag for rug-typical patterns. Ghost dumps don't fire signals.

03 / PAIR

Match against CEX

Cross-reference dump token against the same listing on every CEX (spot & perp). Compute spread = CEX price / DEX price. Only spreads ≥10% with valid CEX liquidity qualify.

04 / DELIVER

Buy DEX → Short CEX

Signal includes: dump origin, FDV, days, liquidity warning, recommended trade direction with the best CEX leg, funding rate (the hold can run hours), DEX swap deeplink.

Coverage

Chains and venues we monitor for dumps.

Detection happens on-chain. Settlement happens on CEX perpetuals. Both sides need to be live for an alert to fire.

What lands in your DEX-Dump channel.

Header shows the price move (-47% in 5min), chain, top spread vs CEX, profit at $1k. Then the timeframe row (5M / 1H / 6H / 24H) for context — is this a one-off blip or the start of something bigger.

Below — token info (name, days, liquidity, FDV) and the recommended trade direction. The FUTURES table lists every perp venue trading the token with funding rates, since the hold can span funding cycles.

Dashboard

Track the dump as it unfolds.

Live dumps shows pools currently in active drawdown — enter while the spread is widest. The pool snapshot updates every 2s so you see the price move in real time.

Closed dumps archives the last 24h of resolved signals — useful for reviewing entry/exit timing on your own trades.

DEX-Dumps FAQ

Practical questions about flashcrash arb.

How fast do I need to react to a DEX-Dump signal?

Inside 1–3 minutes for the entry leg. The DEX moves first; CEX takes 5–15 minutes to catch up. The window where the spread is biggest is in the first 2–3 minutes. After that the spread halves quickly. Setup matters: have a Solana wallet funded, perp accounts margined, swap router pre-bookmarked.

What's the worst-case loss?

The dump keeps going while you hold the short. Mitigation: exit when the CEX catches up to within 5% of DEX, not when it fully closes. The signal carries an anti-fake-dump heuristic — pools that look like rug-style dumps where liquidity vanishes get flagged separately. Avoid chasing those.

Why short on CEX perp instead of CEX spot?

Two reasons. First, you don't need to own the token on the CEX side — perp is just a margin position. Second, perp gives you instant exit liquidity. Spot exit means selling into a thin book at the bottom of a panic. Perps clear at index price.

What's the typical hold time?

5–15 minutes for the spread to close. Sometimes 30+ if the CEX takes longer to react (illiquid token, hot market). The funding rate over those holds is small — 0.01–0.05%. Negligible compared to the 20–40% spread you're capturing.

Can I do this with $500 or do I need $5k+?

Both work. The pool depth column tells you max realistic size before slippage on the DEX side. On Solana with $1.4M pools, $1–3k trades fine. On smaller pools ($100–300k), $500 is the safe ceiling. Some operators run $10k+ on the deepest pools but that's a different risk profile.
