Field Descriptions

Below you can find some key types descriptions.

All types descriptions can be found in GraphQL schema as it is self-descriptive. Just go to playground and click "DOCS". Docs in Playground are the latest.

These types are met in most of GraphQL queries result data.

Account type

Recall that a smart contract and an account are the same thing in the context of the Everscale Blockchain, and that these terms can be used interchangeably, at least as long as only small (or “usual”) smart contracts are considered. A large smart-contract may employ several accounts lying in different shardchains of the same workchain for load balancing purposes.

An account is identified by its full address and is completely described by its state. In other words, there is nothing else in an account apart from its address and state.

Can be queried by following fields:

FIELD	TYPE	DESCRIPTION
id	string	Account address in raw format
acc_type	uint8	The current status of the account according to original Everscale blockchain specification: uninitialized - 0, active - 1,frozen - 2
last_paid	uint256	Contains either the unixtime of the most recent storage payment collected (usually this is the unixtime of the most recent transaction), or the unixtime when the account was created (again, by a transaction)
due_payment	hex string (uint256)	If present, accumulates the storage payments that could not be exacted from the balance of the account, represented by a strictly positive amount of nanotokens; it can be present only for uninitialized or frozen accounts that have a balance of zero tokens (but may have non-zero balances in other cryptocurrencies). When due_payment becomes larger than the value of a configurable parameter of the blockchain, the ac- count is destroyed altogether, and its balance, if any, is transferred to the zero account.
last_trans_lt	uint64	the last account's transaction logic time
balance	uint128	Account balance in nanotokens
balance_other	{ currency: uint32, value: hex string (uint256) }	Array of other currency balances
split_depth	uint8	Number of the split depth for large contracts. Is present and non-zero only in instances of large smart contracts.
tick	bool	May be present only in the masterchain—and within the masterchain, only in some fundamental smart contracts required for the whole system to function
code	base64	If present, contains smart-contract code encoded with in base64
data	base64	If present, contains smart-contract data encoded with in base64

FIELD TYPE DESCRIPTION

FIELD	TYPE	DESCRIPTION
id	string	transaction hash
tr_type	int	Transaction type according to the original blockchain specification, clause 4.2.4. ordinary - 0, storage - 1, tick - 2, tock - 3, splitPrepare - 4, splitInstall - 5, mergePrepare - 6, mergeInstall - 7
status	unknown - 0, preliminary - 1, proposed - 2, finalized - 3, refused - 4	Transaction processing status
block_id	string	block hash
account_addr	uint256	Address of an account for the transaction (Tip: check the notion of an Account collection in the specification)
lt		Transaction logical time. LT and the account address define the transaction on the blockchain
prev_trans_hash		hash of the previous transaction for the account
prev_trans_lt		logical time of a previous transaction for the account
now		block creation time
outmsg_cnt		The number of generated outbound messages (one of the common transaction parameters defined by the specification)
orig_status		The initial state of account. Note that in this case the query may return 0, if the account was not active before the transaction and 1 if it was already active
end_status		The end state of an account after a transaction, 1 is returned to indicate a finalized transaction at an active account
in_msg		Dictionary of transaction inbound message ID's as specified in the specification
in_message		Dictionary of transaction inbound messages as specified in the specification
out_msgs		Dictionary of transaction outbound message ID's as specified in the specification
out_message		Dictionary of transaction outbound messages as specified in the specification
total_fees		Total amount of fees that entails account state change and used in Merkle update
total_fees_other		Same as above, but reserved for other coins that may appear in the blockchain
old_hash, new_hash	uint256	Hashes of the account state before and after the transaction
credit_first
STORAGE (phase)		The storage phase is present in ordinary, merge, split, storage and tock transactions, so a common representation for this phase includes three fields. The first defines the amount , the second can be empty, the third specifies the account status change
storage_fees_collected, storage_fees_due, status_change		Fields show amounts related to storage fees and account status change (e.g. it may be frozen or remain active (unchanged))
CREDIT (phase)		The account is credited with the value of the inbound message received. The credit phase can result in the collection of some due payments
due_fees_collected		The sum of `due_fees_collected` and credit must equal the value of the message received, plus its `ihr_fee` if the message has not been received via Instant Hypercube Routing, IHR (otherwise the `ihr_fee` is awarded to the validators).
credit
credit_other
COMPUTE (phase)		The code of the smart contract is invoked inside an instance of TVM with adequate parameters, including a copy of the inbound message and of the persistent data, and terminates with an exit code, the new persistent data, and an action list (which includes, for instance, outbound messages to be sent). The processing phase may lead to the creation of a new account (uninitialized or active), or to the activation of a previously uninitialized or frozen account. The gas payment, equal to the product of the gas price and the gas consumed, is exacted from the account balance. If there is no reason to skip the computing phase, TVM is invoked and the results of the computation are logged. Possible parameters are covered below.
compute_type		0: skipped, then only `skipped_reason` is defined. 1: not skipped, then other fields for the phase are filled
skipped_reason		Reason for skipping the compute phase. According to the specification, the phase can be skipped due to the absence of funds to buy gas, absence of state of an account or a message, failure to provide a valid state in the message
success		This flag is set if and only if `exit_code` is either 0 or 1.
msg_state_used		This parameter reflects whether the state passed in the message has been used. If it is set, the `account_activated` flag is used (see below)
account_activated		The flag reflects whether this has resulted in the activation of a previously frozen, uninitialized or non-existent account.
gas_fees		This parameter reflects the total gas fees collected by the validators for executing this transaction. It must be equal to the product of `gas_used` and `gas_price` from the current block header.
gas_used		See above
gas_limit		This parameter reflects the gas limit for this instance of TVM. It equals the lesser of either the tokens credited in the credit phase from the value of the inbound message divided by the current gas price, or the global per-transaction gas limit.
gas_credit		This parameter may be non-zero only for external inbound messages. It is the lesser of either the amount of gas that can be paid from the account balance or the maximum gas credit
mode
exit_code, exit_arg		These parameters represent the status values returned by TVM; for a successful transaction, `exit_code` has to be 0 or 1
vm_steps		the total number of steps performed by TVM (usually equal to two plus the number of instructions executed, including implicit RETs)
vm_init_state_hash, vm_final_state_hash		These parameters are the representation hashes of the original and resulting states of TVM
ACTION (phase)		If the smart contract has terminated successfully (with exit code 0 or 1), the actions from the list are performed. If it is impossible to perform all of them—for example, because of insufficient funds to transfer with an outbound message—then the transaction is aborted and the account state is rolled back. The transaction is also aborted if the smart contract did not terminate successfully, or if it was not possible to invoke the smart contract at all because it is uninitialized or frozen.
success
valid
no_funds		The flag indicates absence of funds required to create an outbound message
status_change		Account status change according to the list of statuses provided by the specification
total_fwd_fees		Amount in tokens
total_action_fees		Amount in tokens
result_code
result_arg
tot_actions
spec_actions
skipped_actions
msgs_created
action_list_hash		Hash of the action list created during the compuation phase
total_msg_size_cells
total_msg_size_bits
BOUNCE (phase)		If the transaction has been aborted, and the inbound message has its bounce flag set, then it is “bounced” by automatically generating an outbound message (with the bounce flag clear) to its original sender. Almost all value of the original inbound message (minus gas payments and forwarding fees) is transferred to the generated message, which otherwise has an empty body.
bounce_type		0 - Negfunds, 1 - Nofunds, 2 - Ok
msg_size_cells
msg_size_bits
req_fwd_fees
msg_fees
fwd_fees		Amount to be bounced back
aborted		The flag is set either if there is no action phase or if the action phase was unsuccessful. The bounce phase occurs only if the `aborted` flag is set and the inbound message was bounceable.
destroyed
tt
split_info		The fields below cover split prepare and install transactions and merge prepare and install transactions, the fields correspond to the relevant schemes covered by the blockchain specification.
cur_shard_pfx_len		length of the current shard prefix
acc_split_depth
this_addr
sibling_addr
prepare_transaction
installed
proof

BlockMasterShardHashesDescr type

ShardHashes is represented by a dictionary with 32-bit workchain_ids as keys, and “shard binary trees”, represented by TL-B type BinTree ShardDescr, as values. Each leaf of this shard binary tree contains a value of type ShardDescr, which describes a single shard by indicating the sequence number seq_no, the logical time lt, and the hash hash of the latest (signed) block of the corresponding shardchain.

FIELD	TYPE	DESCRIPTION
seq_no	uint32	sequence number
reg_mc_seqno	string	Representation hash of shard block's root cell. Returns last known master block at the time of shard generation. The shard block configuration is derived from that block.
start_lt		Logical time of the shardchain start.
end_lt		Logical time of the shardchain end.
root_hash	string	Representation hash of shard block's root cell. Returns last known master block at the time of shard generation. The shard block configuration is derived from that block.
file_hash		Shard block file hash.
before_split	bool	Everscale Blockchain supports dynamic sharding, so the shard configuration may change from block to block because of shard merge and split events. Therefore, we cannot simply say that each shardchain corresponds to a fixed set of accountchains. A shardchain block and its state may each be classified into two distinct parts. The parts with the ISP-dictated form of will be called the split parts of the block and its state, while the remainder will be called the non-split parts. The masterchain cannot be split or merged.
