Storage functions¶

FeeLessChannelIds¶

storage map. key is tuple of (source_channel.sequence(), destination_channel.sequence()) and value () that means that this group of channels is feeless

Python¶

result = substrate.query(
    'Ics20Fee', 'FeeLessChannelIds', [('u64', 'u64')]
)

Return value¶

()

ServiceChargeIn¶

Python¶

result = substrate.query(
    'Ics20Fee', 'ServiceChargeIn', []
)

Return value¶

'u32'

Constants¶

PalletId¶

Value¶

'0x6963733230666565'

Python¶

constant = substrate.get_constant('Ics20Fee', 'PalletId')

ServiceChargeIn¶

ServiceChargeIn represents the service charge rate applied to assets upon receipt via IBC.

The charge is applied when assets are delivered to the receiving side, on deliver(before to mint, send assets to destination account) extrinsic using the Inter-Blockchain Communication (IBC) protocol.

For example, if the service charge rate for incoming assets is 0.04%, ServiceChargeIn will be configured in rutime as parameter_types! { pub IbcIcs20ServiceChargeIn: Perbill = Perbill::from_rational(4_u32, 1000_u32 ) };

Value¶

Python¶

constant = substrate.get_constant('Ics20Fee', 'ServiceChargeIn')
