micro-eth-signer/src/address.ts

Lines 37 to 46 in 3208304

addChecksum(nonChecksummedAddress: string): string {
const low = addr.parse(nonChecksummedAddress).data.toLowerCase();
const hash = bytesToHex(keccak_256(low));
let checksummed = '';
for (let i = 0; i < low.length; i++) {
const hi = Number.parseInt(hash[i], 16);
const li = low[i];
checksummed += hi <= 7 ? li : li.toUpperCase(); // if char is 9-f, upcase it
}
return add0x(checksummed);
