Network specific features and requirements for Cosmos SDK based wallets.

Cosmos SDK is a framework used to build application specific blockchains. This page describes features that are common across Cosmos based networks when using IBM Digital Asset Haven wallets.

Supported networks
IBM Digital Asset Haven supports the following Cosmos SDK networks:
  • Cosmos Hub
  • Babylon Genesis
  • Sei Pacific (Cosmos transactions only)
Message based transactions
Cosmos SDK uses a message based transaction model. Each transaction contains one or more messages, and each message represents an action such as sending tokens, staking, or voting
Transfer messages
IBM Digital Asset Haven uses the standard MsgSend message type for native token transfers. Some networks may define additional message types for chain specific functionality.
Transfers
Use the Transfer Asset endpoint for Cosmos transfers.
  • Native tokens: Use kind: Native (for example, ATOM on Cosmos Hub)
  • Memo: Cosmos transactions support an optional memo field for notes or application level identifiers
On Sei Pacific, only Cosmos based transactions are indexed. EVM transactions on Sei are not supported through the Cosmos interface.
