No, contract replacement refers to the transaction mode of asset replacement through futures contracts, which usually involves two different assets, such as digital currency, crude oil and gold. When exchanging contracts, both parties will negotiate to use a specific futures contract for exchange and deliver at the agreed price. Unlike contract replacement, swap refers to the way of trading through the exchange of different currencies. In currency exchange transactions, both parties will negotiate to use different currencies for exchange, usually involving two different currencies, such as RMB and USD, Euro and GBP. At the time of exchange, both parties shall exchange according to the agreed exchange rate. Therefore, contract replacement and currency swap are two different trading methods, in which contract replacement refers to the trading method of asset replacement through futures contracts, and currency swap refers to the trading method of different currency swaps.
