Signature

將簽名從對象轉換為元組格式，壓縮簽名。

從 @kaiachain/ethers-ext 軟件包中導入 getSignatureTuple

要將公鑰從{r, s, v}格式壓縮為元組格式，請使用 getSignatureTuple 並將簽名對象作為參數

要將公鑰從緊湊的 65 字節格式壓縮成元組，請使用 getSignatureTuple 並將緊湊簽名作為參數

signatureUtils.js


const { getSignatureTuple } = require('@kaiachain/ethers-ext/v5')
async function main() {
  console.log(
    'signature from { v, r, s } object =',
    getSignatureTuple({
      v: 27,
      r: '0x66809fb130a6ea4ae4e823baa92573a5f1bfb4e88e64048aecfb18a2b4012b99',
      s: '0x75c2c3e5f7b0a182c767137c488649cd5104a5e747371fd922d618e328e5c508',
    })
  )
  console.log(
    'signature from compact 65 bytes =',
    getSignatureTuple(
      '0x66809fb130a6ea4ae4e823baa92573a5f1bfb4e88e64048aecfb18a2b4012b9975c2c3e5f7b0a182c767137c488649cd5104a5e747371fd922d618e328e5c5081b'
