Implementations

impl TransactionApi

pub fn register_bridge( &self, bridge_contract_address: H160, initial_peers: Vec<AccountId32>, signature_version: BridgeSignatureVersion ) -> StaticTxPayload<RegisterBridge>

Register a new bridge.

Parameters:

• bridge_contract_address - address of smart-contract deployed on a corresponding network.
• initial_peers - a set of initial network peers.

pub fn add_asset( &self, asset_id: AssetId32<PredefinedAssetId>, network_id: u32 ) -> StaticTxPayload<AddAsset>

Add a Thischain asset to the bridge whitelist.

Can only be called by root.

Parameters:

• asset_id - Thischain asset identifier.
• network_id - network identifier to which the asset should be added.

pub fn add_sidechain_token( &self, token_address: H160, symbol: String, name: String, decimals: u8, network_id: u32 ) -> StaticTxPayload<AddSidechainToken>

Add a Sidechain token to the bridge whitelist.

Parameters:

• token_address - token contract address.
• symbol - token symbol (ticker).
• name - token name.
• decimals - token precision.
• network_id - network identifier.

pub fn transfer_to_sidechain( &self, asset_id: AssetId32<PredefinedAssetId>, to: H160, amount: u128, network_id: u32 ) -> StaticTxPayload<TransferToSidechain>

Transfer some amount of the given asset to Sidechain address.

Note: if the asset kind is Sidechain, the amount should fit in the asset’s precision on sidechain (SidechainAssetPrecision) without extra digits. For example, assume some ERC-20 (T) token has decimals=6, and the corresponding asset on substrate has 7. Alice’s balance on thischain is 0.1000009. If Alice would want to transfer all the amount, she will get an error NonZeroDust, because of the 9 at the end, so, the correct amount would be 0.100000 (only 6 digits after the decimal point).

Parameters:

• asset_id - thischain asset id.
• to - sidechain account id.
• amount - amount of the asset.
• network_id - network identifier.

pub fn request_from_sidechain( &self, eth_tx_hash: H256, kind: IncomingRequestKind, network_id: u32 ) -> StaticTxPayload<RequestFromSidechain>

Load incoming request from Sidechain by the given transaction hash.

Parameters:

• eth_tx_hash - transaction hash on Sidechain.
• kind - incoming request type.
• network_id - network identifier.

pub fn finalize_incoming_request( &self, hash: H256, network_id: u32 ) -> StaticTxPayload<FinalizeIncomingRequest>

Finalize incoming request (see Pallet::finalize_incoming_request_inner).

Can be only called from a bridge account.

Parameters:

• request - an incoming request.
• network_id - network identifier.

pub fn add_peer( &self, account_id: AccountId32, address: H160, network_id: u32 ) -> StaticTxPayload<AddPeer>

Add a new peer to the bridge peers set.

Parameters:

• account_id - account id on thischain.
• address - account id on sidechain.
• network_id - network identifier.

pub fn remove_peer( &self, account_id: AccountId32, peer_address: Option<H160>, network_id: u32 ) -> StaticTxPayload<RemovePeer>

Remove peer from the the bridge peers set.

Parameters:

• account_id - account id on thischain.
• network_id - network identifier.

pub fn prepare_for_migration( &self, network_id: u32 ) -> StaticTxPayload<PrepareForMigration>

Prepare the given bridge for migration.

Can only be called by an authority.

Parameters:

• network_id - bridge network identifier.

pub fn migrate( &self, new_contract_address: H160, erc20_native_tokens: Vec<H160>, network_id: u32, new_signature_version: BridgeSignatureVersion ) -> StaticTxPayload<Migrate>

Migrate the given bridge to a new smart-contract.

Can only be called by an authority.

Parameters:

• new_contract_address - new sidechain ocntract address.
• erc20_native_tokens - migrated assets ids.
• network_id - bridge network identifier.

pub fn register_incoming_request( &self, incoming_request: IncomingRequest ) -> StaticTxPayload<RegisterIncomingRequest>

Register the given incoming request and add it to the queue.

Calls validate and prepare on the request, adds it to the queue and maps it with the corresponding load-incoming-request and removes the load-request from the queue.

Can only be called by a bridge account.

pub fn import_incoming_request( &self, load_incoming_request: LoadIncomingRequest, incoming_request_result: Result<IncomingRequest, DispatchError> ) -> StaticTxPayload<ImportIncomingRequest>

Import the given incoming request.

Register’s the load request, then registers and finalizes the incoming request if it succeeded, otherwise aborts the load request.

Can only be called by a bridge account.

pub fn approve_request( &self, ocw_public: Public, hash: H256, signature_params: SignatureParams, network_id: u32 ) -> StaticTxPayload<ApproveRequest>

Approve the given outgoing request. The function is used by bridge peers.

Verifies the peer signature of the given request and adds it to RequestApprovals. Once quorum is collected, the request gets finalized and removed from request queue.

pub fn abort_request( &self, hash: H256, error: DispatchError, network_id: u32 ) -> StaticTxPayload<AbortRequest>

Cancels a registered request.

Loads request by the given hash, cancels it, changes its status to Failed and removes it from the request queues.

Can only be called from a bridge account.

pub fn force_add_peer( &self, who: AccountId32, address: H160, network_id: u32 ) -> StaticTxPayload<ForceAddPeer>

Add the given peer to the peers set without additional checks.

Can only be called by a root account.

pub fn remove_sidechain_asset( &self, asset_id: AssetId32<PredefinedAssetId>, network_id: u32 ) -> StaticTxPayload<RemoveSidechainAsset>

Remove asset

Can only be called by root.

pub fn register_existing_sidechain_asset( &self, asset_id: AssetId32<PredefinedAssetId>, token_address: H160, network_id: u32 ) -> StaticTxPayload<RegisterExistingSidechainAsset>

Register existing asset

Can only be called by root.
