Wei

A micro-framework for working with $ETH cryptocurrency

Note: Requires Swift 5.2+

TL;DR

Take any String, Integer, or Float and instanteously convert it to Wei:

  • 1(as: .ether);
  • "1"(as: .ether);
  • 1.0(as: .ether);

Convert Wei between denominations:

1(as: .gwei).to(.wei) // 1000000 WEI

Test Examples


/** Given this array of values:
let value = [
    [ "wei"   :"1" ],
    [ "kwei"  :"1" ],
    [ "mwei"  :"1" ],
    [ "gwei"  :"1" ],
    [ "micro" :"1" ],
    [ "milli" :"1" ],
    [ "ether" :"1" ],
]
 */

Test Case '-[WeiTests.WeiTests testDenominationCodable]' started.
"1" WEI   is: 1 WEI
"1" KWEI  is: 1000 WEI

"1" MICRO is: 1000000000000 WEI
