Fetching All Pairs | Agora Finance

Every AgoraStableSwapFactory keeps an on-chain registry of every pair it deploys. This guide shows how to query all available pairs using the wallet client created earlier.

The convenient view function getAllPairData() returns:

Field	Description
`pairAddress`	Proxy address of the pair contract
`token0 / token1`	Structs containing address, name, symbol, and decimals

1. Pick a factory address

1 // AgoraStableSwapFactory contract on Avalanche Fuji Testnet
2 const TESTNET_FACTORY = '0x237591AaF2FCCb34464Ceae9EeA1eb6f375843AF';

2. Helper to read the purchase fees

1 /**
2  * Returns an array of pair data for every pool created by the factory.
3  */
4 async function getAllPairData(factory: `0x${string}`) {
5   return await client.readContract({
6     address: factory,
7     abi: stableSwapFactoryAbi,
8     functionName: "getAllPairData",
9   });
10 }

3. Run the query

1 (async () => {
2   const allPairData = await getAllPairData(TESTNET_FACTORY);
3   console.log(allPairData);
4 })();
