Java

The Java integration is delivered via the DIF Universal Resolver and Universal Registrar drivers maintained by Danube Tech.

• uni-resolver-driver-did-btcr2
• uni-registrar-driver-did-btcr2

Status — Driver-only. There is no standalone Java SDK at this time; JVM consumers should drive the operations via the Universal Resolver / Registrar HTTP APIs.

Install

Both drivers are distributed as Docker images. Pull and run via docker compose; see the per-driver READMEs for compose snippets.

POST https://uniregistrar.io/1.0/create?method=btcr2
