What this monitor is — and what it is not
The Live Spot Arbitrage Monitor on ArbDecoded is not a signal service, not a promise of profit, and not a simulation.
It is a raw, real-time view of price differences between crypto exchanges — exactly as they appear in the market.

What we actually measure
For each asset, the system continuously checks:
- Best ask price on a buy exchange
- Best bid price on a sell exchange
- Gap percentage (spread) between buy and sell
- Estimated notional value on both sides (USDT)
- Withdrawal network compatibility
- Withdrawal fees, normalized to USDT
The gap you see is not theoretical — it is computed from live order books.
Why “gap %” alone is not enough
Many arbitrage tools stop at price difference.
We don’t.
A gap is only meaningful if:
- The asset can be withdrawn from the buy exchange
- The deposit network is supported on the sell exchange
- Withdrawal fees don’t erase the spread
- The prices are available at real liquidity, not fake depth
That’s why the monitor also shows:
- Matched blockchain networks
- Estimated withdrawal fee in USDT
- Prices on other exchanges for context
Exchanges currently covered
The monitor currently tracks spot markets across major exchanges, including:
- Binance
- MEXC
- Gate.io
- CoinEx
- Bybit
- KuCoin
- Bitget
Coverage expands over time as infrastructure and data quality allow.
What this tool is designed for
This monitor is built for:
- Traders who want transparent data
- Analysts studying real market inefficiencies
- Developers validating arbitrage logic
- Anyone tired of exaggerated arbitrage claims
It is not designed for fast-click trading or guaranteed execution.
A note on risk and reality
Spot arbitrage in the real world is:
- Low margin
- Operationally constrained
- Sensitive to fees, delays, and limits
If done correctly, market direction risk is minimal —
but execution risk is always real.
This tool exists to make those constraints visible.
Transfer taxes and fee-on-transfer tokens
Not all tokens behave the same when transferred.
Some tokens implement a transfer tax directly at the smart contract level.
This fee is applied every time the token is transferred, regardless of exchange or network.
This fee is not the exchange withdrawal fee.
It is enforced by the token contract itself and usually takes the form of:
- A percentage deducted on transfer (e.g. 1%–10%)
- Burn mechanisms
- Redistribution to holders or treasury addresses
Why this is dangerous for arbitrage
In spot arbitrage, this creates hidden losses because:
- The transfer tax is not visible in order books
- The deducted amount reduces the actual received balance
- The tax applies even if withdrawal fees are low
- The loss happens after the trade decision is made
A price gap that looks profitable can instantly turn negative once the token is transferred.
Contract-level behavior matters
Even if two exchanges list the same symbol:
- The token may have different contract logic
- The transfer tax may be active on one network but not another
- Wrapped or bridged versions may behave differently
If the contract deducts value on transfer, no amount of price difference can compensate for it.
Real-world outcome
In practice, these tokens cause losses because:
- Capital arrives smaller than expected
- Hedging or resale calculations break
- Execution assumptions become invalid
This is why serious arbitrage systems must be aware of: contract behavior — not just prices.
Seeing a gap is easy.
Surviving the transfer is the real challenge.
Use it as a lens, not a promise
Think of the Live Spot Arbitrage Monitor as a diagnostic instrument:
- It shows where gaps appear
- It shows why many gaps are not usable
- It reveals how fragile most “opportunities” really are
