Operations

GET /explorer/op/{hash|id}

The operations endpoint returns info about a single operation or a list of related operations. Because Tezos supports batch operations (multiple operations sharing the same hash) and internal operations (created by smart contract calls in response to a transaction) this endpoint always returns an array of operation objects. In many cases this array contains one element only. Use the optional prim (boolean) parameter to embed Michelson primitive trees with smart contract calls. Use meta (boolean) to add optional account metadata.

Schema

Field	Description
id uint64	Global unique id.
hash hash	Operation hash.
type enum	Operation type.
block hash	Block hash at which the operation was included on-chain.
time datetime	Block time at which the operation was included on-chain.
height int64	Block height at which the operation was included on-chain.
cycle int64	Cycle in which the operation was included on-chain.
counter int64	Unique sender account 'nonce' value.
op_n int64	In block operation counter.
op_p int64	Tezos RPC operation list position.
status enum	Operation status applied, failed, backtracked, skipped.
is_success bool	Flag indicating operation was successfully applied.
is_contract bool	Flag indicating smart-contract calls.
is_event bool	Flag indicating an event, i.e. state changes that don't have an operation hash such as bake, unfreeze, seed_slash, airdrop, invoice, migration, subsidy, deposit, reward, bonus, stake_slash and internal versions of stake, unstake, finalize_unstake.
is_internal bool	Flag indicating if this operation was sent be a smart contract.
is_rollup bool	Flag indicating this is a rollup related operation.
gas_limit int64	Caller-defined gas limit.
gas_used int64	Gas used by the operation.
storage_limit int64	Caller-defined storage limit.
storage_paid int64	Part of the storage the operation paid for.
volume money	Amount of tokens transferred in tz. In denunciation operations, this field contains the accuser reward, in delegation operations this field contains the initially delegated balance.
fee money	Fees paid in tez. In denunciation operations, this field contains the offender loss as negative value.
reward money	Rewards earned in tez. In denunciation operations, this field contains the offender loss as negative value.
deposit money	Amount of deposited tokens in tez. In denunciation operations, this field contains the offender loss as negative value.
burned money	Amount of burned tokens in tez.
data polymorph	Extra type-dependent operation data. See below.
errors array	Native Tezos RPC errors.
parameters object	Call parameters as embedded JSON object, contract-only.
script object	Embedded Micheline script on originations.
storage object	Updated contract storage as embedded JSON object, contract-only. Optional, use storage=1 to add.
big_map_diff object	Inserted, updated or deleted bigmap entries as embedded JSON object, contract-only. Optional, use storage=1 to add.
value object	Micheline data for global constants.
code_hash bytes	Short hash to uniquely identify the receiver contract, first 8 bytes of the SHA256 hash over binary encoded Michelson script code.
sender hash	Operation sender (note some event types have no sender).
receiver hash	Transaction receiver, may be empty. For activation the source account is referenced when the activation merged coins from a second blinded account (i.e. when a fundraiser signed up twice). For delegation the previous delegate is referenced.
source hash	In internal operations, source is the original signer of the outer transaction.
creator hash	Contains contract creator on origination. For nonce_revelation the actual seed publisher is referenced.
baker hash	New baker, only used by origination and delegation. When empty for a delegation the operation was a withdrawal.
previous_baker hash	On re-delegations, contains the previous baker.
accuser hash	For double bake/endorse this is the account who sent the accusation.
offender hash	For double bake/endorse this is the account who was slashed.
level int64	Rollup level, rollup ops only.
power int64	Endorsing power (in number of slots), (pre)endorsement only.
limit money	Deposits limit, set deposit limit op only.
solution bytes	VDF operation solution bytes
proof bytes	VDF operation proof bytes
confirmations int64	Number of blocks following the inclusion of this operation. Usually 6 blocks are OK to consider an operation final (not subject to reorg).
metadata object	Use meta=1 to embed optional account metadata for sender, receiver, delegate, creator. May be empty if no account has metadata defined.
events array	List of emitted on-chain events. Kathmandu+
ticket_updates array	List of emitted ticket updates. Lima+

Event

Event Sub-Schema

Field	Description
contract hash	Event emitter contract
type object	Micheline encoded event type
payload object	Micheline encoded value
tag string	Event tag defined by the contract author
type_hash hash	Unique type hash as uint64 in hex format. Hash is sha256(type_no_annots)

Ticket

Ticket Update Sub-Schema

Field	Description
ticketer hash	Ticket issuer contract
type object	Micheline encoded ticket type
content object	Micheline encoded ticket content
account hash	Owner account of the ticket
amount bigint	Amount of tickets owned by account
