FLP/sFLPトークン価格取得

1

SDKの使用（高度な統合）

const getLpTokenPrices = async () => {
    await flashClient.loadAddressLookupTable(POOL_CONFIG)
    const stakedLpPrice = await flashClient.getStakedLpTokenPrice(POOL_CONFIG.poolAddress, POOL_CONFIG); // sFLP price
    const compoundingLPTokenPrice = await flashClient.getCompoundingLPTokenPrice(POOL_CONFIG.poolAddress, POOL_CONFIG); // FLP price

    console.log('stakedLpPrice :>> ', stakedLpPrice);
    console.log('compoundingLPTokenPrice :>> ', compoundingLPTokenPrice);
}

APIの使用（迅速で簡単）

すべてのプールの価格データを取得するには、以下のエンドポイントをクエリしてください：

https://api.prod.flash.trade/earn-page/data

✅ レスポンス形式（例）

レスポンスはpoolsの配列を含むJSONオブジェクトであり、それぞれがユニークなFLPプールを表しています。各キーの意味は以下の通りです：

フィールド	説明
poolAddress	流動性プールのユニークなオンチェーンアドレス
aum	このプールの運用資産（USD建て）
flpTokenSymbol	複利運用FLPトークンのシンボル（例：FLP.1、FLP.2）
sFlpTokenSymbol	ステークドFLPトークンのシンボル（例：sFLP.1、sFLP.2）
flpDailyApy	複利運用FLPトークンの日次APY（自動再投資）
flpWeeklyApy	複利運用FLPトークンの週次APY
flpWeeklyApr	複利運用FLPトークンの週次APR（非複利運用）
sFlpDailyApr	ステークドFLPトークンの日次APR（非複利運用）
sFlpPrice	ステークドFLPトークンの現在価格
flpPrice	複利運用FLPトークンの現在価格
sFlpPriceWithYield	利回りが評価に含まれる場合のsFLPトークンの導出価格

🔎 使用方法

トークン価格を取得するには：

• flpTokenSymbol（例："FLP.1"）またはpoolAddressを照合して、希望するプールを特定します。

• 複利運用FLPトークンにはflpPriceを、ステーク版にはsFlpPriceを使用します。

これは、SDKのセットアップやブロックチェーンのクエリなしに、リアルタイムの価格設定と利回りデータを必要とするフロントエンドやダッシュボードにとって最も簡単な方法です。
