pub struct ChainMetadata {
    pub slot_time: SlotTime,
}
Expand description

Chain metadata accessible to both receive and init methods. Information about the chain available to smart contracts.

Fields§

§slot_time: SlotTime

The objective (i.e., the entire network agrees on it) time of the block in whose context the smart contract is being executed.
