Arbitrage

What is Arbitrage?

Arbitrage is buying an asset where it is slightly cheaper and selling it where it is slightly pricier, pocketing the difference after costs. Think of spotting the same sneakers cheaper across town, then flipping them for a small, clean win.

How Arbitrage works

Here is a quick walk through using two exchanges and one token. Nothing fancy, just timing and math.

• Step 1: You notice ETH is 1,845 on Exchange A and 1,855 on Exchange B.
• Step 2: You buy on A at the lower price, preferably with a market or limit order that actually fills.
• Step 3: You move the ETH to B or you already have inventory on B ready to sell.
• Step 4: You sell on B at the higher price before the spread closes.
• Step 5: You count profit after trading fees, gas, and any transfer costs.

Price gaps show up for lots of reasons, often tied to uneven order books and different buyers on each venue. A common driver is Liquidity Variations, which is a fancy way of saying some pools are deeper than others.

Why Arbitrage Matters

So what does this do for you and the market as a whole?

• Benefit: It can be a steady trickle of small wins that add up if you keep costs tight.
• Perspective: It helps align prices across venues and chains, so one token does not feel like two different assets.
• Relevance: You will see it on centralized exchanges, DEXs, and even during NFT mints with price references in stablecoins.

Key Characteristics of Arbitrage

These traits tend to show up again and again:

1. Speed: Price gaps often last minutes or less, so execution timing rules the outcome.
2. Neutrality: You are not betting on up or down, you are exploiting a difference.
3. Fee focus: Profit lives in the small print, so costs and slippage decide if a trade works.

Variations

Same idea, different routes to the spread:

• Cross exchange: Buy on one exchange and sell on another.
• Triangular: Cycle through three pairs on one venue to lock a tiny gain.
• Cross chain: Move or mirror exposure between chains when prices drift.
• Funding rate: Hedge spot against perps when funding tilts too far.
• Stat arb: Use data and probability to trade mean reversion in related assets.

Example

Buy 2 ETH at 1,845 on Exchange A, sell 2 ETH at 1,855 on Exchange B, net about 20 before fees and gas.

Fun Fact

Old school traders used telegraph lines to spot price gaps between cities, and some even sent prices by carrier pigeon to beat rivals by a few minutes. Same idea, better Wi Fi now.

Wrap-Up

Short take: find a price gap, move fast, let costs be your compass, repeat when it makes sense.
