Address

Utils for converting public address, public key.

Import the getCompressedPublicKey from @kaiachain/ethers-ext packages

From an Account object you can get the public address with address_from_private_key or get the compressed public key with compressed_key

From x and y coordinates of an uncompressed public key, you can get the public key and the address using compressed_key_from_xy and compressed_key_and_address_from_xy
