Cosmos

This page includes details for working with Cosmos environment chains.

Addresses

Because Wormhole works with many environments, the Wormhole address format is normalized. For Cosmos-based chains, this means a Wormhole formatted address is the bech32 format converted to hex. E.g. xpla137w0wfch2dfmz7jl2ap8pcmswasj8kg06ay4dtjzw7tzkn77ufxqfw7acv becomes 0x8f9cf727175353b17a5f574270e370776123d90fd74956ae4277962b4fdee24c.

Emitter

The emitter address on Cosmos chains is the contract's canonical address, normalized to the Wormhole address format.
