Wallet Interoperability Special Interest Group (SIG)¶
The Wallet Interoperability SIG explores how different wallet systems can interoperate across technical stacks, ecosystems, and standards. It promotes collaboration around APIs, protocols, and integration patterns that enable wallet-to-wallet and wallet-to-service compatibility.
This SIG was accepted by the TAC on June 14, 2023.

About This SIG¶
The Wallet Interoperability SIG provides a forum to coordinate and align on cross-compatibility between wallet systems. The group investigates how to achieve interoperability through shared protocols, capability declarations, API patterns, and common data models.
It encourages participation from implementers, standards contributors, and service integrators.

Deliverables and Workstreams¶
This SIG is currently focused on:
- Exploring cross-ecosystem interoperability use cases
- Mapping existing wallet-to-wallet or wallet-to-service integration efforts
- Identifying opportunities to support or align with relevant standards
The SIG will incrementally publish interoperability documentation, comparison tables, and guidance materials as its work evolves.
