Key

A public key that can be associated with a Dango account. Discriminated by key family.

Definition

type Key =
  | { secp256k1: Base64 }    // compressed pubkey
  | { ethereum: Address }    // EOA address
  | { secp256r1: Base64 }    // compressed pubkey
 
const KeyTag = {
  secp256r1: 0,
  secp256k1: 1,
  ethereum: 2,
} as const

Construction

import type { Key } from "@left-curve/sdk"
 
const k1: Key = { secp256k1: "Ahw5..." }
const eth: Key = { ethereum: "0x1234567890abcdef1234567890abcdef12345678" }
const r1: Key = { secp256r1: "BJw5..." }

Notes

  • Use the in operator or check the present field to narrow: 
    if ("secp256k1" in key) { /* ... */ }
  • KeyTag is the discriminant value the chain uses when packing a key into a salt — see createAccountSalt.
