Convert Ethereum hex style address to bech32 via Javascript

harmoyeah · March 9, 2022, 7:25pm

Hi folks,

Do you know if there is a native Harmony Javascript SDK method to convert an address from hex to bech32?

I found this excellent npm package called bech32-converting, but I wonder if there already is a solution built into the current JS SDK.

Thanks in advance for your help.

You can use the Harmony JS SDK to do this.

github.com

harmony-one/sdk/blob/3c7061887f25c6ba8def5af05672cdc4f44eb2dc/packages/harmony-crypto/src/bech32.ts#L187

      
        
              } else if (bits >= fromWidth || (acc << (toWidth - bits)) & maxv) {
                return null;
              }
            
            
  return Buffer.from(ret);
            };
            
            
/**
             * toBech32Address
             *
             * bech32Encodes a canonical 20-byte Ethereum-style address as a bech32 Harmony
             * address.
             *
             * The expected format is one1<address><checksum> where address and checksum
             * are the result of bech32 encoding a Buffer containing the address bytes.
             *
             * @param {string} 20 byte canonical address
             * @returns {string} 38 char bech32 bech32Encoded Harmony address
             */
            export const toBech32 = (address: string, useHRP: string = HRP): string => {
              if (!isAddress(address)) {

Also this I wrote in Python… More of an API service… GitHub - johnashu/harmony_convert_address: Service to convert One Addresses to ETH format
