  • Having a private ECDSA key

  • Take the corresponding public key generated with it (33 bytes, 1 byte 0x02 (y-coord is even), and 32 bytes corresponding to X coordinate)
0250863ad64a87ae8a2fe83c1af1a8403cb53f53e486d8511dad8a04887e5b2352
  • Perform SHA-256 hashing on the public key

  • Perform RIPEMD-160 hashing on the result of SHA-256

  • Add version byte in front of RIPEMD-160 hash (0x00 for Main Network)

  • Perform SHA-256 hash on the extended RIPEMD-160 result

  • Perform SHA-256 hash on the result of the previous SHA-256 hash

  • Take the first 4 bytes of the second SHA-256 hash. This is the address checksum

  • Add the 4 checksum bytes from stage 7 at the end of extended RIPEMD-160 hash from stage 4. This is the 25-byte binary wallet Address.
