Transfer

The Transfer entity represents a successful native token (CSPR) transfer on the Casper network. Transfers are tracked from the WriteTransfer transforms found in the deploy execution results.

Properties

The Transfer entity has the following properties:

Property Type Description

Property	Type	Description
`id`	`uint64`	Transfer identifier provided by the deploy caller if the deploy is a native transfer. Default is `0`.
`deploy_hash`	`string(64)`	Deploy hash represented as a hexadecimal string
`block_height`	`uint64`	Height of the block in which the transfer happened
`transform_key`	`string(64)`	`WriteTransfer` transform key represented as a hexademical string
`initiator_account_hash`	`string(64)`	Deploy caller account hash represented as a hexadecimal string
`from_purse`	`string(73)`	Source purse URef in the `uref-dead...beef-007` format
`to_purse`	`string(73)`	Target purse URef in the `uref-dead...beef-007` format
`to_account_hash`	`string(64)`	Transfer recipient account hash represetnted as a hexadecimal string
`amount`	`string`	Transfer amount in motes. The type is `string` to avoid overflow in languages that don't support uint64, which is the correct type.
`timestamp`	`string`	Deploy creation timestmap in the ISO 8601 format

id

uint64

Transfer identifier provided by the deploy caller if the deploy is a native transfer. Default is 0.

deploy_hash

string(64)

Deploy hash represented as a hexadecimal string

block_height

uint64

Height of the block in which the transfer happened

transform_key

string(64)

Target purse URef in the uref-dead...beef-007 format

to_account_hash

string(64)

Transfer recipient account hash represetnted as a hexadecimal string

amount

string

Transfer amount in motes. The type is string to avoid overflow in languages that don't support uint64, which is the correct type.
