Variants

relay

Fields

rates: BoundedVec<(T::Symbol, u64), T::MaxRelaySymbols>

resolve_time: u64

request_id: u64

Relay a list of symbols and their associated rates along with the resolve time and request id on BandChain.

Checks if:

• The caller is a relayer;
• The resolve_time for a particular symbol is not lower than previous saved value, ignores this rate if so;

If rates contains duplicated symbols, then the last rate will be stored.

• origin: the relayer account on whose behalf the transaction is being executed,
• rates: symbols with rates in USD represented as fixed point with precision = 9,
• resolve_time: symbols which rates are provided,
• request_id: id of the request sent to the BandChain to retrieve this data.

force_relay

Fields

rates: BoundedVec<(T::Symbol, u64), T::MaxRelaySymbols>

resolve_time: u64

request_id: u64

Similar to [relay()] but without the resolve time guard.

Should be used in emergency situations i.e. then previous value was relayed by a faulty/malicious actor.

• origin: the relayer account on whose behalf the transaction is being executed,
• rates: symbols with rates in USD represented as fixed point with precision = 9,
• resolve_time: symbols which rates are provided,
• request_id: id of the request sent to the BandChain to retrieve this data.

add_relayers

Fields

account_ids: Vec<T::AccountId>

Add account_ids to the list of trusted relayers.

Ignores repeated accounts in account_ids. If one of account is already a trusted relayer an Error::AlreadyATrustedRelayer will be returned.

• origin: the sudo account on whose behalf the transaction is being executed,
• account_ids: list of new trusted relayers to add.

remove_relayers

Fields

account_ids: Vec<T::AccountId>

Remove account_ids from the list of trusted relayers.

Ignores repeated accounts in account_ids. If one of account is not a trusted relayer an Error::AlreadyATrustedRelayer will be returned.

• origin: the sudo account on whose behalf the transaction is being executed,
• account_ids: list of relayers to remove.

set_dynamic_fee_parameters

Fields

fee_parameters: FeeCalculationParameters
