VC Playground Enhancements
Credentials or credential offers can be communicated to any Web or Native wallet via CHAPI.
Now provides multiple API support for different issuance APIs. Choose between CHAPI, VC-API Issuance, OID4VCI, or use VC-API Exchanges to offer both VC-API Issuance & OID4VCI.

VC-API Exchanges and Other Protocols
VC-API Exchanges enable reusable parts. Issuers and Verifiers initiate exchange workflows which then use any supported protocol compatible to directly deliver to a or receive a presentation from a Wallet.
Wallet A
Wallet B
Wallet C
VC-API HTTP Post
OID4VCI / OID4VP
DIDComm
VC-API Exchange (Uses VC-API issuer and verifier internally)
Issuer
Verifier
Define “Workflows” by providing:
Presentation Requests and/or Credentials to Issue
CHAPI or protocol-specific QR code for wallet to scan to deliver URL to exchange

Community responses to the
VC Playground
“The VC playground makes the exchange of credentials real. For wallet holders, it's just like using the Pinterest extension to collect images, but the credentials being collected, stored and verified have value in a much broader ecosystem of opportunities.“
- Kimberly Wilson Linson, Director of Credential Ecosystems
"The team at Digital Bazaar continues to impress me with their knack for intuitive design of complex processes. Their latest extensions to the VC Playground make it seamless to simulate a standards-based credential request from a verifier to a wallet, complete with status and confirmation reporting. Additionally, with recent enhancements to the wallet registration process, native wallets like the Universal Talent Passport, receive the same first-class experience as web wallets. Tools like this are exactly what we need to ensure standards compliance among practitioners in our community.”
– Kayode Ezike, CTO
Territorium is pleased to extend our wallet interoperability capabilities with the VC Playground. We already supported wallet export using the CHAPI protocol. With the Plugfest 3 initiative we were able to extend our wallet import use case as well as demonstrate the ability to allow for verifiable presentations.
