Quoter and Swap

In this section, we provide examples of using the iZiSwap SDK to implement price inquiry (through Quoter contract) and swap (through Swap contract). These are two of the most common and frequent operations in DEX.

Price inquiry means pre-querying amount of token acquired or token needed to pay. For example, if you want to swap 1 ETH to USDC, you can use the Quoter contract to get how much USDC can you get based on the current liquidity conditions.

Swap means invoking real trading with given exact paying amount or exact acquiring amount.

Based on exact paying amount (amount mode) or exact acquiring amount (desired mode), they are processed by different interfaces. For example, if you want to swap M ETH to N USDC, if M is pre-determined, and N is acquired by the Quoter contract, the amount mode is invoked. Otherwise, if N is pre-determined and M is acquired by the Quoter contract, this is the desired mode situation.

Quoter and Swap are 2 different contracts and the deployed contracts can be found in the corresponding section.
