Features

formatEther

BasedUtils.formatEther(BigInt("6900000000000000000000000000")) // "6900000000"

parseEther

BasedUtils.parseEther("1") // BigInt("1000000000000000000")
BasedUtils.parseEther("1", .gwei) // BigInt("1000000000")

parseUnits

BasedUtils.parseUnits("40", 18) // BigInt("40000000000000000000")

isAddress

BasedUtils.isAddress("0x220866B1A2219f40e72f5c628B65D54268cA3A9D") // true
BasedUtils.isAddress("220866B1A2219f40e72f5c628B65D54268cA3A9D") // false
BasedUtils.isAddress("0x220866B1A2219f40e72f5c628B65D54268cA3A9") // false

isSameAddress

let address1 = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
let address2 = "0x220866B1A2219f40e72f5c628B65D54268cA3A9D"
BasedUtils.isSameAddress(address1, address1) // true
BasedUtils.isSameAddress(address1, address2) // false

shortenAddress

let address1 = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
BasedUtils.shortenAddress(address1) // "0xd8dA...6045"

Extensions

Data

let data = "https://example.com".data(using: .utf8)!
data.base64UrlEncode() // "aHR0cHM6Ly9leGFtcGxlLmNvbQ"

String

let address = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
let hash = "d8dA6B"
hash.addHexPrefix() // "0xd8dA6B"
address.addHexPrefix() // "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" (only adds if it doesn't exist)
address.removeHexPrefix() // "d8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
