The IOTA Developer Hub

Welcome to the IOTA developer hub. You'll find comprehensive guides and documentation to help you start working with IOTA as quickly as possible, as well as support if you get stuck. Let's jump right in!

Get Started    

Here we list and describe all additional parameters which are required to be passed along for certain commands.

  • seed: string tryte encoded string which contains the accounts seed. The seed must be correctly encoded trytes: only uppercase latin letters and 9’s. No other characters are allowed. The maximum security level is 81-trytes, but you can choose longer/shorter seeds.
  • address: string 81-trytes long address of the recipient of a transaction.
  • value: string the quantity of IOTA’s which should be transferred.
  • message: string tryte-encoded string which can contain arbitrary information and is sent alongside a transaction. The message value is publicly visible. The max value is 2187 trytes, which is 6561 trits (or roughly 1312 bytes).
  • transaction / hash: string hash of a transaction. A single transaction hash is 81-chars long.
  • trytes: string the raw data of a transaction.
  • bundles: list contains a list of transaction bundles. Bundles are basically linked, individual transactions which were created with a single transfer. They are uniquely identified by a 27-char hash.
  • addresses : list a list of addresses. A single address is 81-chars long.
  • tags: list the tag of a transaction.
  • approvees: list a list of transaction which were referenced by this transaction
  • securityLevel: int specifies the security level of your transaction. Can either by 0 (for 81-trit security), 1 (for 162-trit security) and 2 (for 243-trit security). Lower security transactions are faster to generate.
  • minWeightMagnitude: int specifies the amount of Proof of Work that will be carried out. Currently can only take the value 18.
