Voyager CosmWasm Proof Module

Section titled “Voyager CosmWasm Proof Module”

This module provides state proof querying functionality for the Union IBC stack deployed on CosmWasm. State proofs are read through abci_query, under the storage key defined here.

Configuration

Section titled “Configuration”

  • rpc_url: String. The CometBFT RPC url for this CosmosSDK based chain. The node that this points to must support historical state proofs (this is usually enabled by default for all CosmosSDK nodes, however some chains have optimization settings for higher performance that may disable historical state commitments).

  • ibc_host_contract_address: Bech32. The address of the deployed ibc-union contract on this chain. The contract will be checked to see if it exists at startup. Canonical deployments can be found here.

Module Info

Section titled “Module Info”

This module only provides proofs for the ibc-union IBC specification.
