查看Aura池的奖励代币／收益

选择池子，移至“Info”标签，然后在Etherscan上打开奖励合约地址“Rewards Contract Address”。

rewardRate 是每秒的BAL奖励产生率
extraRewards(N) 是额外奖励的合约地址 (AURA, BAL, ie. LDO, bb-a-USD 以外)

AURA会按照所累积的BAL进行按比例的铸造。

计算每个BAL可以获得多少AURA的公式：https://etherscan.io/token/0xC0c293ce456fF0ED870ADd98a0828Dd4d2903DBF#code#F1#L85

以下是一个 TypeScript 的实作：

export const getAuraMintAmount = (
  balEarned: number,
  global: Omit<Global, 'auraMinter' | 'auraMinterMinted'>,
) => {
  const reductionPerCliff = BigNumber.from(global.auraReductionPerCliff);
  const maxSupply = BigNumber.from(global.auraMaxSupply);
  const totalSupply = BigNumber.from(global.auraTotalSupply);
  const totalCliffs = BigNumber.from(global.auraTotalCliffs);
  const minterMinted = BigNumber.from(0);
 
  // e.g. emissionsMinted = 6e25 - 5e25 - 0 = 1e25;
  const emissionsMinted = totalSupply.sub(maxSupply).sub(minterMinted);
 
  // e.g. reductionPerCliff = 5e25 / 500 = 1e23
  // e.g. cliff = 1e25 / 1e23 = 100
  const cliff = emissionsMinted.div(reductionPerCliff);
 
  // e.g. 100 < 500
  if (cliff.lt(totalCliffs)) {
    // e.g. (new) reduction = (500 - 100) * 2.5 + 700 = 1700;
    // e.g. (new) reduction = (500 - 250) * 2.5 + 700 = 1325;
    // e.g. (new) reduction = (500 - 400) * 2.5 + 700 = 950;
    const reduction = totalCliffs.sub(cliff).mul(5).div(2).add(700);
    // e.g. (new) amount = 1e19 * 1700 / 500 =  34e18;
    // e.g. (new) amount = 1e19 * 1325 / 500 =  26.5e18;
    // e.g. (new) amount = 1e19 * 950 / 500  =  19e17;
    let amount = simpleToExact(balEarned).mul(reduction).div(totalCliffs);
 
    // e.g. amtTillMax = 5e25 - 1e25 = 4e25
    const amtTillMax = maxSupply.sub(emissionsMinted);
    if (amount.gt(amtTillMax)) {
      amount = amtTillMax;
    }
 
    return amount;
  }
 
  return BigNumber.from(0);
};

请勿使用链上查询

在 AuraMinter.inflationProtectionTime() 过期之后，这个计算可能不再有效。
