Expand description

Trait for various implementations of generators of common on-chain transaction payloads.

Required Methods§

Source

fn approve(&self, spender: Address, amount: Balance) -> Result<T>

Create a ERC20 approve transaction payload. Pre-requisite to open payment channels. The spender address is typically the HOPR Channels contract address.

Source

fn transfer(&self, destination: Address, amount: Balance) -> Result<T>

Create a ERC20 transfer transaction payload

Source

fn announce(&self, announcement: AnnouncementData) -> Result<T>

Creates the transaction payload to announce a node on-chain.

Source

fn fund_channel(&self, dest: Address, amount: Balance) -> Result<T>

Creates the transaction payload to open a payment channel

Source

fn close_incoming_channel(&self, source: Address) -> Result<T>

Creates the transaction payload to immediately close an incoming payment channel

Source

fn initiate_outgoing_channel_closure(&self, destination: Address) -> Result<T>

Creates the transaction payload that initiates the closure of a payment channel. Once the notice period is due, the funds can be withdrawn using a finalizeChannelClosure transaction.
