Context for the contract execution.

Fields

current_account_id: AccountId

The account id of the current contract that we are executing.

signer_account_id: AccountId

The account id of that signed the original transaction that led to this execution.

signer_account_pk: PublicKey

The public key that was used to sign the original transaction that led to this execution.

predecessor_account_id: AccountId

If this execution is the result of cross-contract call or a callback then predecessor is the account that called it. If this execution is the result of direct execution of transaction then it is equal to signer_account_id.

input: Vec<u8>

The input to the contract call. Encoded as base64 string to be able to pass input in borsh binary format.

block_index: BlockHeight

The current block height.

block_timestamp: u64

The current block timestamp (number of non-leap-nanoseconds since January 1, 1970 0:00:00 UTC).

epoch_height: EpochHeight

The current epoch height.

account_balance: Balance

The balance attached to the given account. Excludes the attached_deposit that was attached to the transaction.

account_locked_balance: Balance

The balance of locked tokens on the given account.

storage_usage: StorageUsage

The account's storage usage before the contract execution

attached_deposit: Balance

The balance that was attached to the call that will be immediately deposited before the contract execution starts.

prepaid_gas: Gas

The gas attached to the call that can be used to pay for the gas fees.

random_seed: Vec<u8>

Initial seed for randomness

is_view: bool

Whether the execution should not charge any costs.

output_data_receivers: Vec<AccountId>

How many DataReceipt's should receive this execution result. This should be empty if this function call is a part of a batch and it is not the last action.
