Variants

upgrade

Sends command to the Gateway contract to upgrade itself with a new implementation contract

Fee required: No

• origin: Must be Root.
• impl_address: The address of the implementation contract.
• impl_code_hash: The codehash of the implementation contract.
• initializer: Optionally call an initializer on the implementation contract.

Fields

impl_address: H160

impl_code_hash: H256

initializer: Option<Initializer>

set_operating_mode

Sends a message to the Gateway contract to change its operating mode

Fee required: No

• origin: Must be Location

Fields

mode: OperatingMode

set_pricing_parameters

Set pricing parameters on both sides of the bridge

Fee required: No

• origin: Must be root

Fields

params: PricingParametersOf<T>

create_agent

Sends a command to the Gateway contract to instantiate a new agent contract representing origin.

Fee required: Yes

• origin: Must be Location of a sibling parachain

create_channel

Sends a message to the Gateway contract to create a new channel representing origin

Fee required: Yes

This extrinsic is permissionless, so a fee is charged to prevent spamming and pay for execution costs on the remote side.

The message is sent over the bridge on BridgeHub’s own channel to the Gateway.

• origin: Must be Location
• mode: Initial operating mode of the channel

Fields

mode: OperatingMode

update_channel

Sends a message to the Gateway contract to update a channel configuration

The origin must already have a channel initialized, as this message is sent over it.

A partial fee will be charged for local processing only.

• origin: Must be Location
• mode: Initial operating mode of the channel

Fields

mode: OperatingMode

force_update_channel

Sends a message to the Gateway contract to update an arbitrary channel

Fee required: No

• origin: Must be root
• channel_id: ID of channel
• mode: Initial operating mode of the channel
• outbound_fee: Fee charged to users for sending outbound messages to Polkadot

Fields

channel_id: ChannelId

mode: OperatingMode

transfer_native_from_agent

Sends a message to the Gateway contract to transfer ether from an agent to recipient.

A partial fee will be charged for local processing only.

• origin: Must be Location

Fields

recipient: H160

amount: u128

force_transfer_native_from_agent

Sends a message to the Gateway contract to transfer ether from an agent to recipient.

Privileged. Can only be called by root.

• location: Location used to resolve the agent
• recipient: Recipient of funds
• amount: Amount to transfer

Fields

location: Box<VersionedLocation>

recipient: H160

amount: u128

set_token_transfer_fees

Sends a message to the Gateway contract to update fee related parameters for token transfers.

Privileged. Can only be called by root.

Fee required: No

• origin: Must be root
• create_asset_xcm: The XCM execution cost for creating a new asset class on AssetHub, in DOT
• transfer_asset_xcm: The XCM execution cost for performing a reserve transfer on AssetHub, in DOT
• register_token: The Ether fee for registering a new token, to discourage spamming

Fields

create_asset_xcm: u128

transfer_asset_xcm: u128

register_token: U256

register_token

Registers a Polkadot-native token as a wrapped ERC20 token on Ethereum. Privileged. Can only be called by root.

Fee required: No

• origin: Must be root
• location: Location of the asset (relative to this chain)
• metadata: Metadata to include in the instantiated ERC20 contract on Ethereum

Fields

location: Box<VersionedLocation>

metadata: AssetMetadata
