Valence ICA IBC Transfer Library

The Valence ICA IBC Transfer Library library allows remotely executing an IBC transfer using a Valence interchain account on a remote IBC connected domain. It does that by remotely sending a MsgTransfer to the ICA created by the Valence interchain account on the remote domain. It is typically used as part of a Valence Program. In that context, a Processor contract will be the main contract interacting with the Valence ICA IBC Transfer Library.

Configuration

The library is configured on instantiation via the LibraryConfig type.

#![allow(unused)]
fn main() {
pub struct LibraryConfig {
    // Address of the input account (Valence interchain account)
    pub input_addr: LibraryAccountType,
    // Amount that is going to be transferred
    pub amount: Uint128,
    // Denom that is going to be transferred
    pub denom: String,
    // Receiver on the other chain
    pub receiver: String,
    // Remote chain info
    pub remote_chain_info: RemoteChainInfo,
}

pub struct RemoteChainInfo {
    // Channel ID to be used
    pub channel_id: String,
    // Timeout for the IBC transfer in seconds. If not specified, a default 600 seconds will be used will be used
    pub ibc_transfer_timeout: Option<u64>,
}
