RPC API Reference

Theta offers two sets of RPC APIs. The rationale of this division is to separate the public interface accessible to all users and personal interface that manages a specific user's private wallet.

The Theta APIs is provided by the Theta Node. It is the RPC interface via which a user can interact with the Theta Node directly. As described in the setup guide, the Theta Node can be launched with the following command. By default the Theta node runs its RPC server at port 16888.

theta start --config=<path/to/config/folder>

The ThetaCli APIs is provided by the ThetaCli Daemon. It allows a user to interact with his/her personal Theta Wallet through RPC calls. The wallet can manange multiple accounts simultaneously. The encrypted private keys of the accounts are stored under ~/.thetacli/keys/encrypted/ by default. The RPC APIs supports account creation, lock/unlock, and sending Theta/TFuel. The ThetaCli Daemon can be run by the following command. If the port parameter is not specified, by default it runs at port 16889. Note that part of the ThetaCli Daemon's functionality depends on the Theta Node. Hence we need to have the Theta Node running when we launch the ThetaCli Daemon.

thetacli daemon start --port=

In the examples below, we assume the reader has followed the setup guide to launch both the Theta Node and the ThetaCli Daemon on the local machine at port 16888 and 16889 respectively.

We have also implemented a JavaScript SDK Theta.js for ease of DApp development. Please refer to here for more details.

A block and all the transactions included in the block are considered Finalized by the validators if the block status is either 4, 5, or 6

Block status transitions:

GetBlock Example

In this example, we queried the block with hash 0x9f1e77b08c9fa8984096a735d0aae6b0e43aee297e42c54ce36334103ddd67a7. This block contains two transactions. The first one is a "coinbase" transaction (type 0), and the second is a "send" transaction (type 2). In particular, in the "send" transaction, address 0x2e833968e5bb786ae419c4d13189fb081cc43bab sent 10 Theta and 20 TFuel tokens to address 0x9f1233798e905e173560071255140b4a8abd3ec6, which cost 1000000000000 TFuelWei transaction fee.

GetBlockByHeight

This API returns the finalized block given the height. If none of the blocks at the given height are finalized (either directly or indirectly), the API simply returns an empty result.

RPC Method: theta.GetBlockByHeight

Query Parameters

  • height: the block height (need to pass in as a string instead of an integer)
  • include_eth_tx_hashes: whether to include the ETH tx hash of the smart contract transactions in the response.

Returns

Similar to the returns of the GetBlock API. Please see above.

Example

In this example, we query the block at height 3. The result is similar to the result of the GetBlock API.

GetTransaction Example 2

Smart contract transactions can be used to send TFuel. For example, if you use Metamask to send TFuel following the steps here, the TFuel is sent through a smart contract transaction. In the transaction details, transaction.from.coins.tfuelwei specifies the amount of TFuel (in Wei) sent to the receiver address (see below for more details). Similar to ETH, some of the smart contract transactions just interact with a smart contract. They may not send any TFUEL to the contract. This is a smart contract transaction that did not send any TFuel. On the other hand, this is a smart contract transaction with a non-zero TFuel value. In this example, the transaction sends 702.8783 TFUEL to the receiver address 0x8366537d56cf2b86ca90e9dbc89450207a29f6e3.

The following example show how to query the details of a "smart contract transaction" (i.e., type 7, see the Transaction types). This type of transaction is similar to the Ethereum transaction:

  • transaction.from.address is the sender address of the transaction
  • transaction.to.address is the receiver address of the transaction. It can be a regular wallet, or a smart contract address
  • transaction.from.coins.tfuelwei is the amount of TFuel (in unit wei, i.e. 10e-18 TFuel) send to the receiver address. This corresponds to the value field of an Ethereum transaction. In the example below, the sender is sending 250000000000000000000 TFuelWei (i.e. 250 TFuel) to the receiver address.
  • transaction.gas_limit and transaction.gas_price are the the gas limit and gas price of the transaction, similar to the corresponding fields of an Ethereum transaction.
  • transaction.data is an optional field to include arbitrary data, similar to the data field of an Ethereum transaction.
  • receipt is the receipt generated by the transaction, including the event logs, similar to the Ethereum transaction receipt.

Note : You can also use theta.GetBlock to retrieve all the transactions in a block. The transaction details in the theta.GetBlock response should also contain the above fields.

  • from: The address of the account to send tokens from
  • to: The address of the receipient account

  • fee: The transaction fee in TFuelWei
  • sequence: The expected sequence number of the from account
  • async: A boolean flag. If async is set to false, the RPC call will wait until the transaction has been included in a block, or a timeout reached. Otherwise, the RPC call will return immediately with the transaction hash.
