Transaction Types

0: coinbase transaction, for validator/guardian reward
1: slash transaction, for slashing malicious actors
2: send transaction, for sending tokens among accounts
3: reserve fund transaction, for off-chain micropayment
4: release fund transaction, for off-chain micropayment
5: service payment transaction, for off-chain micropayment
6: split rule transaction, for the "split rule" special smart contract
7: smart contract transaction, for general purpose smart contract
8: deposit stake transaction, for depositing stake to validators/guardians
9: withdraw stake transaction, for withdrawing stake from validators/guardians

Block Status

0: pending 
1: valid
2: invalid
3: committed
4: directly finalized
5: indirectly finalized
6: trusted (the first block in a verified snapshot is marked as trusted)

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:

+-------+          +-------+                          +-------------------+
|Pending+---+------>Invalid|                    +----->IndirectlyFinalized|

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)

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 1

In this example, the transaction being queried is a "send transaction" (i.e., type 2, see the Transaction types. In this transaction, address 0x2e833968e5bb786ae419c4d13189fb081cc43bab sent 10 Theta and 20 TFuel tokens to address 0x9f1233798e905e173560071255140b4a8abd3ec6, which cost 1000000000000 TFuelWei transaction fee.

            }]
        }
    }
}

GetTransaction Example 2

In this example, the transaction being queried is 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.

Send

This API sends the Theta/TFuel tokens. Note the API call can send either Theta tokens or TFuel tokens, or both in one shot.

RPC Method: thetacli.Send

Query Parameters

chain_id: ID of the chain
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.

Returns

hash: the hash of the transaction
block: the details of the block that has included the transaction
