集成挖矿奖励申领
背景
JustLend DAO 于 2023 年 2 月 20 日将存款挖矿奖励发放方式从空投升级为用户主动申领。
详细公告请查看：关于调整 JustLend DAO 奖励发放方式的公告
领取挖矿收益请参阅：如何领取挖矿收益?
从分配合约中手动领取奖励
用户可以在JustLend DAO UI页面默认领取奖励。 如果用户无法从 JustLend DAO UI 中领取奖励，也可以通过触发奖励分配合约手动领取奖励。 例如，用户帐户设置了多签。
通过 Tronscan.org 上的合约领取
目前，如果用户有多个未申领的记录，则只能在 tronscan 上逐一申领。 申领函数名为“claim”，需要 4 个参数。
单笔领取交易样本：
方法及参数：
如何获取参数：
API：https://openapi.just.network/mining/distributions?address=
注：API 访问的频率限制是 10次/秒， 请开发者优化代码逻辑，防止由于访问频率过高引起 API 不稳定。
以TR4AHdK6LKANAcP12Eqdy2t45Dt7PwbpT4为例，用户可以根据需要改成其他地址。 所有参数都可以从 JustLend DAO API 查询，下面是 API 的详细信息。
https://openapi.just.network/mining/distributions?address=TR4AHdK6LKANAcP12Eqdy2t45Dt7PwbpT4
返回值说明：
“22”:{} : 表示一条未领取的记录。如果用户没有认领之前的奖励，将会有多个记录。
以下是触发 claim 函数所需的参数：
“merkleIndex”
“Index”
“amount”
“prooft”
在 Tronscan.rog 上发送交易
填写所有参数，然后单击“发送”按钮。 以下为参数详细信息。
通过 SW 项目领取
以 TronWeb 为例详细说明如何领取。通过 TronWeb 触发 claim 或 multiClaim 函数可以轻松获得奖励。
Claim 的代码示例：
Claim 的代码示例：第一步与 Tronscan 上领取相同，用户需要从 JustLend DAO API 获取所有参数。
