# Arbitrage
#### Arbitraging in traditional finance
Arbitrage, a cornerstone concept in traditional finance, offers investors a strategic way to profit from market inefficiencies while taking minimal risk. At its core, arbitrage involves the simultaneous buying and selling of assets in different markets to exploit price differentials. This practice capitalizes on the inherent tendency of markets to temporarily misprice assets, providing astute traders with the opportunity to secure gains.
**Funding Rate Arbitrage (Basis Trade)**
\
Funding rate arbitrage is a strategy commonly employed in cryptocurrency derivatives trading, particularly in perpetual futures contracts. These contracts are designed to track the price of the underlying asset but do not have an expiration date; instead, they use a mechanism called the funding rate to ensure that the contract price closely mirrors the spot price of the asset.
The funding rate is used to maintain balance between the perpetual futures market and the spot market. It is periodically exchanged between long and short traders based on the difference between the contract price and the spot price. When the contract price is trading above the spot price, long traders pay short traders a funding rate, and vice versa.
Funding rate arbitrage involves taking corresponding long and short positions to capitalize on funding rate discrepancies across different trading venues, both on-chain (DEXs) and centralized exchanges (CEXs).
