CEX — DEX · centralised vs on-chain

Centralised order book
vs the on-chain pool.

Centralised exchanges and on-chain pools price the same token through different mechanisms — order books vs AMM curves. They diverge constantly, and they diverge widest on tail tokens where DEX often moves first. Buy CEX, sell into the pool. Or the reverse. Includes the MEXC-DEX hybrid feed for tokens that live on both inside one venue.

How it works

From pool diff to a Telegram alert.

01 / READ

DEX prices live

DexScreener, OKX-DEX HTML, MEXC-DEX hybrid, direct on-chain pool reads. Every pool above $50k liquidity for tracked tokens. Updates land in Redis the moment they confirm on-chain.

02 / PAIR

Match every CEX listing

For each token with a pool, find every CEX listing the same asset (spot & perp). Cross-pair against pool price. Both directions: CEX cheap (buy CEX, sell pool) and CEX rich (buy pool, sell CEX).

03 / VERIFY

Pool depth + slippage

Walk the AMM curve up to a $1k notional swap. Compute net after pool fees, gas, taker fees on the CEX side. Pool depth column on the alert tells you the realistic max size before you nuke the price.

04 / DELIVER

Swap link + CEX deeplink

Alert includes pool router address with the swap pre-filled, CEX trade page with the right pair, and the cheapest open network for any required deposit. Anti-fake-dump heuristic on every alert so you don't catch a falling knife.

Coverage

17+ chains scanned, every CEX listing paired.

DEX side reads from on-chain. CEX side covers the same 20+ venues as Spot–Spot. The MEXC-DEX hybrid is its own channel — MEXC's own internal cross-venue between their CEX listings and their DEX wrapper.

Signal format

What the CEX–DEX channel sends.

Header carries the token, spread%, magnitude, profit at $1k, and the chain the pool lives on. Buy and Sell rows show the trade direction with a swap link on the DEX side and an exchange deeplink on the CEX side.

The CEX–DEX block lists every venue trading the token, the pool address, liquidity, FDV, and a token-age check (days since pool created — protects against fresh launches that haven't priced yet).

  • Magnitude tiers: HIGH ≥3%, MEDIUM ≥1.5%
  • Pool depth + slippage warning per alert
  • Token age + FDV inline (filter against day-old pools)
  • Anti-fake-dump heuristic flag included

Pool depth + token age in one row.

All CEX–DEX firehose — every pool/CEX combination sorted by spread. Filter by chain, by min liquidity, by min token age (filter out fresh launches that haven't priced).

MEXC-DEX tab is the hybrid feed: MEXC's internal CEX listings against MEXC's own DEX wrapper. Same venue both legs — no cross-exchange transfer needed.

  • Pool address + slippage estimator inline
  • Token age filter (default ≥30 days)
  • Chain quick-filter (SOL / ETH / BSC / Base)
  • Anti-fake-dump heuristic flag on every row
Included in

CEX–DEX is in Spreads and All-in-one.

CEX–DEX (excluding the dump-specific signals) is part of Spreads. DEX-Dumps stays its own channel because the rhythm is different — both available together in All-in-one.

CEX–DEX FAQ

Practical questions about on-chain arbitrage.

How is this different from DEX-Dumps?
DEX-Dumps is the flashcrash subset: 20–40% windows that live 5–15 minutes after a rug, hack or liquidity event. CEX–DEX is the everyday spread between centralised order books and on-chain pools — usually 2–6%, lives minutes, fires steadily through the day. Different rhythm, different size. CEX–DEX is for daily flow; DEX-Dumps is for the rare big windows.
What about gas costs and MEV?
Gas is netted out of the displayed profit. Solana and BSC are cheap enough to ignore on $1k+ trades; Ethereum mainnet is gated to large enough spreads to absorb $5–15 gas. MEV is a real risk on EVM chains — for time-sensitive routes the alert recommends a private RPC (Flashbots Protect, MEV-Blocker) which the swap link supports.
Can I trust the pool depth numbers?
Pool liquidity is read directly from the AMM contract — both reserves, fully accurate at the time of the snapshot. The slippage estimate at $1k uses the actual constant-product / concentrated-liquidity math depending on the pool type. Don't size beyond the displayed depth or your effective price will be very different.
Is the MEXC-DEX hybrid different from regular CEX–DEX?
Yes. MEXC operates both a centralised exchange and an internal DEX wrapper for tail tokens not on the CEX listing. Both legs settle on MEXC — no cross-venue transfer, no on-chain confirmation. Trades are nearly atomic. It's a separate signal because the operator workflow is different (everything inside one venue).
What's the smallest spread that's still worth it?
On SOL/BSC: 1.5% net at $1k clears fees + gas comfortably. On Ethereum mainnet: 3% minimum once you account for variable gas. CEX side fees are 0.1% taker — same as Spot–Spot. Pool fees vary 0.05–1% depending on the pair tier. The displayed profit already accounts for all of these.
