Universal Quoter and SwapΒΆ
Origin examples for Swap and Quoter can only deal with paths without V2 pool.
To help you deal with paths which may contain both V2 pool(or we say iZi Classic Pool) and V3 pool, we newly implement UniversalQuoter and UniversalSwapRouter contracts.
In this section, we provide examples of using the iZiSwap SDK to implement price inquiry (through UniversalQuoter contract) and swap (through UniversalSwapRouter 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 UniversalQuoter contract, the amount mode is invoked. Otherwise, if N is pre-determined and M is acquired by the UniversalQuoter contract, this is the desired mode situation.
UniversalQuoter and UniversalSwap are 2 different contracts and the deployed contracts can be found in the corresponding section.
