Sign in with a BTX address
The apps being built on BTX, and the identity layer they log you in with. No email, no password, no account to make: you already have a BTX address, and that is the account. qID is an open post quantum identity protocol, built by easyBTX.
Apps on BTX
Honest status on each. BTX is young, so this is a short list, and it is meant to be a true one rather than a long one.
Build on BTX
The invitation, not an app: everything you need to ship one. The sign-in button on the page is real, the setup kit is generated for your stack, and it is free and MIT. Your users arrive with the wallet they already have.
Quantum Reflex
Can you out-react a quantum computer? Five rounds, your best four count. Sign in with qID to claim your place on the global leaderboard under the name you forged into your relic.
qID Dashboard
The developer portal for qID Connect: register your app, manage its keys and watch its sign-ins. It is never in your users' login path, so it can never stand between them and their account.
The Last Relic
Soulbound BZA1 keepsakes on BTX, minted and sealed. All 37,777 are claimed and the collection is closed, so the vault is now a place to look, not to mint.
BTC→BTX Bridge
Bring value from Bitcoin into BTX. Signs you in with your BTX address through qID Connect, no email and no password.
Relic Forge
The mint studio for BZA1 artifacts, now retired. It bound each order to your qID so the piece landed in the address that asked for it. The Last Relic closed the L1 set, so there is nothing left to forge.
What qID actually is
An open post quantum identity protocol. It is the thing that logs you into everything above.
One seed, a whole identity
A single 32-byte seed becomes a complete post quantum identity: keys, address, login, recovery and encryption. Pure JavaScript on the NIST standards (FIPS 203, 204 and 205), byte-exact to the BTX chain.
A login that cannot spend
Signing in proves you control an address. It does not authorize a transaction, and it never can. A sign-in proof can never move funds, which is the entire reason the scheme is shaped this way.
No account to make
No email, no password, no signup form, no database of yours to leak. You already have a BTX address, and that is the account.
Building something on BTX?
Start at Build on BTX, the developer hub with a sign-in button you can test on the page. qID Connect is how your app gets that login. Every BTX wallet works with it, including bonuz and PQ Wallet, and it costs nothing.
Two SDKs, one afternoon
A server SDK verifies the challenge and mints the session; a widget drops the sign-in button into your page. You do not implement post quantum cryptography yourself.
Every BTX wallet, free
Your users sign in with bonuz, PQ Wallet or any BTX address they already hold. qID is an open protocol and costs nothing to integrate.
Nothing to store
No passwords, no email list, no reset flow, no breach to disclose. The chain is the source of truth about who someone is.
