How client-side validation complicates wallet SDK architecture: RGB-WDK integration analysis

A CTDG Dev Hub participant introduces an adapter layer for RGB to facilitate seamless integration with wallet SDKs.

Interoperability is crucial for a seamless experience with blockchains and cryptocurrencies. However, it is largely missing in integrations between many existing wallet SDKs and RGB, a protocol for issuing assets and running smart contracts on Bitcoin.

Utexo, a CTDG Dev Hub participant, has introduced RGB support for Tether’s Wallet Development Kit (WDK) via the Utexo SDK. The support essentially reconciles two fundamentally different views of asset state.

Most wallet SDKs are designed around a narrow and well-defined set of responsibilities: managing keys, tracking balances, constructing transactions and interacting with the underlying chain. They assume that asset state is globally observable, derived from the blockchain and updated monotonically.
