ParaSwap V5
In this section, we will introduce the ParaSwap V5 SDK interfaces, which provide developers with a convenient and efficient way to interact with the ParaSwap V5 protocol. These interfaces are related to swap token and are designed to be used easily and flexibly.
The following section will introduce the interfaces related to the ParaSwap V5 protocol, which can be accessed through the api.protocols.paraswapv5.
prefix.
SwapToken
The following code defines interfaces and functions related to the ParaSwap V5 swap token logic:
Types
SwapTokenParams: A type that represents the input parameters for the ParaSwap V5 swap token logic
type SwapTokenParams =
| {
input: {
token: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
amount: string;
};
tokenOut: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
slippage?: number;
excludeDEXS?: string[]
}
| {
tokenIn: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
output: {
token: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
amount: string;
};
slippage?: number;
excludeDEXS?: string[]
};
SwapTokenFields: A type that represents the fields required for the ParaSwap V5 swap token logic.
interface SwapTokenFields {
input: {
token: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
amount: string;
};
output: {
token: {
chainId: number;
address: string;
decimals: number;
symbol: string;
name: string;
};
amount: string;
};
slippage?: number;
excludeDEXS?: string[]
}
SwapTokenLogic: An interface that extends the
Logic
interface and represents the ParaSwap V5 swap token logic. It includes therid
, andfields
properties.
interface SwapTokenLogic {
rid: string;
fields: SwapTokenFields;
}
Functions
getSwapTokenTokenList(chainId: number): An asynchronous function that retrieves the list of tokens supported by the ParaSwap V5 swap token logic on the specified
chainId
.getSwapTokenQuotation(chainId: number, params: SwapTokenParams): An asynchronous function that retrieves a quotation for swapping assets on the ParaSwap V5 protocol with the specified
params
object on the specifiedchainId
.newSwapTokenLogic(fields: SwapTokenFields): A function that creates the ParaSwap V5 swap token logic data with the given
fields
object.
Example Code
import * as api from '@protocolink/api';
const chainId = 1;
const tokenList = await api.protocols.paraswapv5.getSwapTokenTokenList(chainId);
const tokenIn = tokenList[0];
const tokenOut = tokenList[2];
const swapTokenQuotation = await api.protocols.paraswapv5.getSwapTokenQuotation(chainId, {
input: {
token: tokenIn,
amount: '10',
},
tokenOut,
slippage: 100, // 1%
});
const swapTokenLogic = await api.protocols.paraswapv5.newSwapTokenLogic(swapTokenQuotation);
