Frequently asked questions

Everything you need to know about PartyLayer.

Yes! PartyLayer is fully open source under the MIT license. You can view the source code, submit issues, and contribute on GitHub. We believe in transparency and community-driven development.

The registry is a JSON manifest of wallet metadata, served from a single HTTPS origin and published from a public repository, so every change to it is visible in commit history. Each entry is validated against a JSON Schema on every build, and a gate blocks the removal of a wallet's CIP-0103 native flag, because losing that flag silently downgrades how the SDK detects it. The client also supports Ed25519 signature verification, but that path only runs when a consumer configures registryPublicKeys, and no signature is published today. Treat the registry as a version-controlled list served over TLS, not as a cryptographically attested one.

PartyLayer supports all Canton networks including mainnet, testnet, and devnet environments. The SDK automatically detects the connected network and adapts accordingly. Each wallet adapter handles network-specific connection logic.

Common error codes include WALLET_NOT_INSTALLED (wallet app not detected), USER_REJECTED (user declined connection), SESSION_EXPIRED (session timed out), and TRANSPORT_ERROR (communication failure). All errors are typed and documented in the SDK.

The suite covers origin allowlisting and session binding, transport handling, and registry schema validation, and it runs on every build. Registry signature verification is implemented in the client but is not exercised in production, because no signature is published and nothing configures registryPublicKeys. See the security checklist in the docs for what is enforced today.

Wallet providers can apply for registry inclusion by submitting a pull request to the PartyLayer repository. Requirements include implementing the standard adapter interface, passing conformance tests, and providing wallet metadata. See the wallet-provider-guide in our docs.
