qID Connect

qID Connect is a connection layer, in development as of July 2026, that lets applications on the BTX blockchain request sign-in and approvals from a user's wallet. Its role is comparable to WalletConnect in other blockchain ecosystems: a standard channel between an application and whatever wallet the user runs. It is developed alongside qID and documented at qid.dev.

#Motivation

Without a shared connection layer, every application that wants wallet sign-in or transaction approval must integrate each wallet individually, and every wallet must integrate each application. A connection layer replaces this pairwise work with one protocol: the application issues a request, the user's wallet displays it, the user approves or rejects it, and the response returns to the application. In ecosystems built on Ethereum and similar chains, WalletConnect fills this role; qID Connect targets the same interaction pattern for BTX applications. In such systems the application typically presents a pairing code or link, the wallet accepts the pairing, and subsequent requests flow over the established channel with the wallet as the approval surface.

For BTX, the wallets concerned are PQ Wallet on desktop and bonuz wallet on mobile, both of which ship qID for identity.

#Design goal

The stated goal is that applications never handle key material. Keys remain in the wallet, every request is explicit, and every approval is a deliberate user action. Sign-in requests resolve to qID signatures made with the user's post-quantum keys, the same ML-DSA and SLH-DSA key types required by BTX consensus, so an application can verify a login with the same cryptography a node uses to verify a transaction. Approval requests extend the same pattern to actions such as authorizing a transaction that the wallet then signs and broadcasts.

#Status

qID Connect is in development as of July 2026. No protocol version has been published as shipped, and this entry describes the project's stated goal rather than released features. Specifications, transport details, and wallet support will be documented at qid.dev as they are released. Applications that only need sign-in verification can already evaluate qID itself, which is open source and ships inside both BTX wallets.
