Register

Register an account by public key

Registering an account isn't needed to use LTO You can simply sign and broadcast transactions. The register transaction publishes a public key, so a new account can be used for a DID verification method.

  • id and height should be omitted when broadcasting. These fields are set by the node.

  • Binary strings are base58 encoded.

  • timestamp is in microseconds since epoch.

  • fee includes 8 digits, so LTO * 10^8

  • Account key type and public key is repeated for each account.

  • Network id can be obtained by taking the 2nd byte from the sender address.

  • Integers (short, int, long) have a big endian byte order.
