Buying an asset where it appears cheaper and selling it where it appears more expensive can work only if both prices are executable for your order size, the two legs complete, and every trading, network, transfer, financing, custody and tax cost still leaves a positive net result. A visible spread is a potential edge, not a guaranteed profit.
Arbitrage can run between centralized exchanges (CEXs), between decentralized exchanges (DEXs), or from a CEX to a DEX. The controls that matter most are conservative sizing, executable-price calculations, slippage and price limits, small operational tests, limited balances on each venue, and a written response for partial fills, outages and delayed withdrawals.

What crypto arbitrage is—and why the spread can mislead you
An arbitrage trade buys an asset in one market and sells the same asset in another market at a higher price. The positions are intended to offset each other, so the trader is exposed for as little time as possible to the asset’s direction. European Securities and Markets Authority (ESMA) describes the activity this way: “Arbitrage MEV involves taking advantage of price discrepancies across exchanges, namely DEXs (on-chain arbitrage) or a mix of DEXs and CEXs (off-chain arbitrage).” Its report was dated 1 July 2025.

The important distinction is between a quoted spread and a net executable spread. A screen may show a bid on one venue and an ask on another, but the displayed quantity may be small, stale or unavailable to your account. Your order can move the market, incur fees, wait for confirmation, or fail on one side. Only the prices actually available for your intended size, after all costs, determine whether an opportunity exists.

Lower liquidity generally means more slippage and higher user costs. On an order book, depth at successive price levels determines how far a market order moves the price. In an automated-market-maker pool, the trade changes the pool’s reserves; ESMA explains that slippage depends in part on trade size relative to pool liquidity.
The main risks traders face
Price movement and the disappearing spread
Crypto markets can move between the moment you detect a gap and the moment both orders execute. A bot may submit two instructions nearly simultaneously, yet matching engines, network delays and confirmation times are not identical. If the expensive-market sale executes first and the cheap-market purchase fails, you may be short the asset. If the purchase executes first and the sale fails, you hold an unhedged long position. Either outcome converts a planned market-neutral trade into a directional bet.
Price differences can also be non-executable. A top-of-book quote may represent only a fraction of your size, while a pool quote may assume no other transaction changes its reserves before yours is confirmed. Treat every opportunity as a range of possible fills, not as one headline price.

Slippage is the deterioration between a quoted or pre-trade price and the final execution price. ESMA’s decentralised-finance analysis links the size of slippage to order size relative to pool liquidity. The SEC staff has likewise described slippage as the difference between a quoted price and final execution price in its limited statement about certain interfaces for crypto-asset securities.
Slippage can occur on both legs. A large order may consume several order-book levels, or move an automated pool’s price against you. A profitable-looking spread can become negative when the buy leg gets more expensive and the sell leg receives a lower bid. A slippage tolerance is a maximum price change you are willing to accept where the venue or protocol supports one; it does not ensure that a transaction is included, filled, or profitable.

Fees and settlement costs
Gross price difference is not profit. Your calculation should include, where applicable:
- Trading commissions and any maker, taker or tiered charges.
- The spread consumed by crossing an order book.
- Expected slippage at the planned size.
- Blockchain gas, validator or other network fees, including any priority fee.
- Deposit and withdrawal charges, minimums and transfer delays.
- Financing, borrowing or collateral costs when leverage is used.
- Conversion or foreign-exchange costs when venues use different quote currencies.
Fees, supported networks and withdrawal conditions change. Check the venue and the selected network immediately before execution rather than relying on a saved fee table. The SEC staff’s 14 April 2026 statement, whose scope is limited to certain interfaces for crypto-asset securities, identifies parameters such as slippage, gas fees, priority fees and transaction time as relevant to a transaction. Those observations should not be generalized into a universal rule for every crypto trade.
Transaction ordering and maximal extractable value on DEXs
On-chain transactions are broadcast before confirmation. Participants who can observe pending transactions may influence which transactions are selected or ordered. ESMA discusses maximal extractable value (MEV), including front-running and sandwich attacks. In a sandwich, another transaction is placed before and after yours, moving the pool price against your swap and then trading after your execution.
These tactics can worsen execution or add cost. Their likelihood and effect vary by chain, protocol, liquidity and transaction path. A private transaction route may alter who sees a pending transaction, but no route should be treated as a guarantee without current evidence about its operation. A slippage limit bounds the price deterioration you accept; it cannot guarantee inclusion, prevent a revert, or remove all ordering risk.
Exchange, counterparty and custody exposure
Cross-venue arbitrage often requires capital to remain on multiple venues so both legs can be placed without waiting for a transfer. That convenience creates concentration and counterparty exposure. An exchange outage, withdrawal pause, account restriction, insolvency event or custody failure can leave one leg open while your funds are inaccessible.
FINMA’s guidance published 12 January 2026 highlights the risks of safeguarding crypto-assets and the need for expertise and robust technical infrastructure. A hardware wallet can be appropriate for a longer-term reserve that is not needed for active execution, but it does not protect balances left on an exchange, prevent a failed trade, or insure against market loss.
The Federal Reserve’s material on payment, clearing, settlement and recording systems provides a general framework—not crypto-specific advice—for four useful risk categories:
- Credit risk: a counterparty may not deliver money or assets owed.
- Liquidity risk: you may be unable to meet an obligation when due, even if you are solvent overall.
- Operational risk: systems, people, controls or communications may fail.
- Legal risk: an obligation or claim may not be enforceable as expected.
These categories explain why a mathematically attractive spread can still produce a loss or a stranded position.
Smart-contract, protocol and pool-liquidity risk
A DEX trade depends on contract code, token behavior, interfaces, oracles where used, and available pool liquidity. A bug, exploit, paused protocol or sudden liquidity withdrawal can interrupt a strategy or make unwinding expensive. Token contracts can also impose transfer restrictions or nonstandard behavior that a quoted interface does not make obvious.
Do not confuse swapping against a pool with depositing assets as a liquidity provider. Liquidity providers face impermanent loss: the value of their deposited reserves can differ from simply holding those assets outside the pool. ESMA’s 11 October 2023 analysis cites historical research on Uniswap v3 pools representing 43% of that protocol’s total value locked in 2021; in certain selected pools, the share of users who lost more from impermanent loss than they gained in trading fees was reported as high as 70–75%. Those figures describe historical liquidity-provider results, not arbitrage-trader losses, and cannot be used as a success or failure rate for arbitrage.

Legal and tax treatment depends on your jurisdiction, the asset, the venue and the nature of your activity. There is no universal rule established here for every trader. A sequence of buys, sells, transfers, staking actions or borrowing can create separate reporting events even when the strategy is intended to be market-neutral.
Keep contemporaneous records of orders, fills, timestamps, fees, wallet addresses, transaction hashes, transfers, deposits, withdrawals and balances. Ask a qualified adviser about the rules that apply where you live and operate. Recordkeeping is prudent control, not a substitute for jurisdiction-specific advice.
CEX and DEX arbitrage: the practical trade-offs
Neither venue type is universally safer or more profitable. Compare the actual route, asset and size using these dimensions:
| Dimension | CEX execution | DEX execution |
|---|---|---|
| Custody model | The venue or its custodian holds assets while funds are deposited; access depends on account controls and venue operations. | You normally sign transactions from your own wallet, but contract and wallet-security risks remain. |
| Liquidity and price impact | Order-book depth and available counterparties determine fills; displayed depth can disappear. | Pool reserves and the constant-product or other market-making design determine price impact; your trade changes the pool price. |
| Costs | Trading fees, spread, deposits, withdrawals and possible transfer costs. | Swap fees, network gas, priority fees and any bridge or transfer cost, plus price impact. |
| Settlement dependence | Withdrawals, account reviews, maintenance and venue solvency can delay movement of funds. | Block inclusion, confirmations, congestion and contract execution determine settlement. |
| Transaction ordering | Matching-engine sequencing is controlled by the venue and is not the same as public mempool ordering. | Pending transactions can be observed and reordered; front-running and sandwich exposure may apply. |
| Controls and contingencies | Order types, price bands, withdrawal allowlists and account limits vary by venue. | Slippage settings, deadline parameters and transaction-fee choices vary by protocol and interface. |
How to calculate a defensible net edge
Use executable estimates at the intended size, not the first price displayed. A simple framework is:
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsExpected net result = sale proceeds − purchase cost − trading fees − slippage impact − network fees − deposit/withdrawal costs − financing costs − other conversion costs.
Estimate the buy and sell legs independently. For an order book, walk through the levels needed to fill the quantity. For a pool, use the protocol’s quote for that quantity and inspect the stated price impact. Then apply the venue’s current fee schedule and the network fee estimate for the exact transaction path. If the remaining edge is smaller than normal market movement, fee variation or estimation error, treat it as no edge.
Do not use a universal fee percentage: rates, tiers, gas prices and withdrawal rules vary by venue, network, account and time. Recalculate immediately before sending orders and again if either quote changes.

- Define the complete route. Write down the asset, quote currencies, venues, wallet addresses, network, order type, intended size and whether funds are pre-positioned. Identify every transfer or bridge rather than assuming settlement is instant.
- Verify executable liquidity. Inspect order-book depth or pool reserves for both legs at your size. Reduce the size until estimated impact is acceptable, or reject the opportunity.
- Compute the net edge. Include both sides’ fees, spread, expected slippage, gas or other network charges, withdrawal and deposit costs, and any borrowing expense. Use conservative estimates rather than the best displayed quote.
- Set limits before submission. Use limit orders, price bounds, deadlines and supported slippage limits where available. Decide the maximum acceptable loss from execution deterioration; never widen a limit impulsively just to complete a trade.
- Run a small operational test. Confirm that deposits, withdrawals, token contracts, address formats and the chosen network work with a small amount. Check that the receiving venue credits the exact asset and network you selected.
- Pre-position only necessary capital. Keep the minimum operational balance on each venue or protocol. Separate active trading funds from longer-term reserves and maintain contingency liquidity for fees, margin or an emergency unwind.
- Monitor both legs and timeouts. Record order IDs and transaction hashes. Set a clear time after which an unfilled, pending or reverted leg triggers your contingency plan.
- Reconcile and record. After completion, verify fills, fees, balances, confirmations and transfers. Save the records needed to investigate discrepancies and meet applicable reporting obligations.
What to do when the trade goes wrong
Only one order fills
Stop submitting new size until you know your exposure. Determine whether canceling the filled leg, completing the other leg at a controlled limit, or reducing the position is least damaging under current liquidity. Avoid turning a small failed arbitrage into an unplanned directional position by waiting for the spread to return.
A DEX transaction is pending or reverts
Check the transaction status, nonce, gas setting, deadline and protocol message before resubmitting. A replacement transaction can create duplicate exposure if the original later confirms. If it reverted, verify whether gas was still charged and whether any token transfer occurred.
A withdrawal is delayed or paused
Do not count inaccessible funds as available hedge capital. Contact the venue through its official support channel, preserve the status evidence, and size any offsetting trade as a separate risk decision. Maintain enough liquidity elsewhere to meet obligations without assuming a specific restoration time.
The venue or protocol becomes unavailable
Freeze new transfers to the affected destination, review open orders and collateral, and activate the contingency venue or wallet route you documented in advance. Diversification reduces concentration but does not eliminate correlated market, technology or regulatory failures.
Risk-management checklist
- Calculate net edge from executable prices at the intended size.
- Check depth, pool liquidity and likely price impact on each leg.
- Include trading, network, transfer, withdrawal and financing costs.
- Use conservative order sizes and price or slippage limits.
- Decide in advance how to handle partial fills, failed legs, reverts, outages and delayed withdrawals.
- Limit funds held at each venue and protocol to operational needs.
- Test addresses, token contracts and transfer routes with small amounts.
- Understand confirmation conditions, transaction fees and the exact on-chain execution path.
- Keep complete order, fill, fee, transfer and balance records.
- Reassess assumptions whenever liquidity, costs, venue status, network conditions or rules change.
Bottom line
Crypto arbitrage is a race against execution, settlement and operational uncertainty. The spread is worth pursuing only after conservative, size-specific quotes still show a net edge and you have a credible response to a one-sided fill or inaccessible funds. Controls can reduce exposure; they cannot guarantee completion, profitability or recovery from a venue, protocol or market failure.
