Upon execution of ABI calls, i.e scripts being executed, a JSON object representing a list of receipts will be returned to the caller. Below is the JSON specification of the possible receipt types. The root will be receipts_root which will include an array of receipts.
{
"receipts_list":[
{
"type":"<receipt_type>",
...
},
...
]
} All receipts will have a type property:
type: String; the type of the receipt. Can be one of:
Then, each receipt type will have its own properties. Some of these properties are related to the FuelVM's registers, as specified in more detail here.
Important note: For the JSON representation of receipts, we represent 64-bit unsigned integers as a JSON String due to limitations around the type Number in the JSON specification, which only supports numbers up to 2^{53-1}, while the FuelVM's registers hold values up to 2^64.
type: Panic. id: Hexadecimal string representation of the 256-bit (32-byte) contract ID of the current context if in an internal context. null otherwise. reason: Decimal string representation of an 8-bit unsigned integer; panic reason. pc: Hexadecimal string representation of a 64-bit unsigned integer; value of register $pc. is: Hexadecimal string representation of a 64-bit unsigned integer; value of register $is. contractId: Optional hexadecimal string representation of the 256-bit (32-byte) contract ID if applicable. null otherwise.
