How KaChat could use PegLab — and what “real” means

KaChat (kachat.org, vsmirn0v/KaChat) is encrypted chat plus native KAS payments on Kaspa (kchat:1:pay memos, timeout reclaim). It already runs. What it does not have is a unit that stays still while two people argue over a price in a thread.

The unit is a KAS receipt (Parker) or a named USD later. Lab tPEG is not that unit.

PegLab today cannot sit in KaChat as money. This repo is Testnet-10, tiny pool, one admin price. If you treat tPEG as USD it depegs. tPEG cannot pay KaChat — same rule as Parker’s wTestUSD cannot buy crops. Authority: DOCTRINE.md.

What KaChat is today

The product freeze: people will chat, then refuse to send because KAS moved since the quote. That is the same merchant “don’t spend KAS” problem. A centralized stable on another chain does not fix in-chat Kaspa settlement.

Where PegLab would show up in KaChat

Not as “USDT in the bubble.” As chat actions that keep a number still:

1. Quote in the receipt, pay in the receipt

“20 000 000 sompi locked” stays that quantity until paid or the timeout fires. The thread is the invoice. Not tPEG. Not $.

1. Pay with timeout (compose, don’t rewrite chat)

Lock the receipt in a covenant. Recipient claims. If they ghost, sender reclaims after timeout. That is KaChatPayTimeout with Parker’s receipt as the asset instead of raw KAS.

1. Group split / tip / chess stake

Same covenant family: lock, split, release, or refund. Chat is coordination; L1 is the court.

1. Bots and agents

A bot quotes work in the unit, KaChat shows the 402 / pay button, sponsor pays KAS fees so the human is not told to go buy dust first.

1. Display honesty

If the unit is a KAS receipt (1 unit = 1 sompi), the UI says sompi, not dollars. If someone later hosts real USDC, that is a different asset id. Never show tPEG as $.

KaChat does not need PegLab to encrypt. It needs PegLab (or a successor unit) so the pay button is not an FX trade.

Two honest units (pick one in the first sentence)

Default for KaChat: A now, B when a real dollar is on Kaspa. C stays the public depeg demo so nobody “just lists tPEG.”

Work credits / grams (WorkCredit.sil) are a fee voucher (KIP-21 mass), not a chat dollar. Useful so messages have prepaid grams. Different button from “pay the designer.”

What must be built to make A real

Order matters. Skipping to mainnet chat-pay is how you mint a bridge IOU.

1. PegLab (or receipt) on Testnet-10 for real

• Broadcast genesis, mint, transfer, redeem — not only the JS engine.
• Pin series / genesis outpoint / template hash. Wallets verify those, not the word “tPEG”.
• Kill the admin USD oracle for the KaChat asset. Receipts do not need a dollar feed.
• Indexer (or KaChat’s Kasia indexer) must see UNIT UTXOs and balances by address.

2. A wallet KaChat already is

KaChat is a Swift wallet (Secure Enclave, node pool, UTXO subscribe). KasWare-on-the-web is not enough.

• Sign receipt lock / transfer / redeem from the iOS or Android KaChat wallet. KasWare is desktop-only and is not enough. There is no PC KaChat.
• Show UNIT balance next to KAS.
• Refuse unknown series. A cloned ticker is not funds.

3. Chat protocol

Extend pay, do not invent a second messenger:

• Keep kchat:1:pay for KAS.
• Add something like kchat:1:payunit (or a typed field): series id, covenant id, amount, timeout, memo ciphertext.
• Handshake still E2E. Payment still a recipient-addressed (or covenant) tx the recipient’s watcher can see.
• Timeout reclaim uses the same idea as KaChatPayTimeout.sil.

4. Fees (“who pays the KAS”)

A “dollar-shaped” pay that first says “go get KAS for mass” is dead UX.

• Sponsor-fee input on the pay tx, or
• Prepaid grams (WorkCredit) consumed when sending chat+pay,
• UI: user thinks in the unit; KAS is the postage.

5. Product copy in the app

• Asset picker: KAS | PegLab receipt | (later) named USD.
• No $ glyph on tPEG.
• Child Mode / gifts: receipts only, not a “stable”.
• No in-app sale of tPEG.

6. Still not a bank

If KaChat ever shows USD, the issuer is named, freeze is disclosed, and PegLab is not that issuer. Licensed payment stables are a company, not a chat feature.

Suggested build order

What not to do

• Do not put current PegLab tPEG in KaChat 4.x as “stablechat”.
• Do not raise money against a KaChat-PegLab token.
• Do not use an admin oracle as the dollar in production.
• Do not wait for Circle before shipping timeout-KAS pay (KaChatPayTimeout can go live on KAS now).

Short version: KaChat is the conversation. The unit is a KAS receipt (Parker) or a named USD later. Lab tPEG cannot pay KaChat. Real means a receipt signer in the phone app, a pay payload, and postage in KAS/grams — not a tiny pool that pretends to be $1.

The rest of the product — phones vs PC, copy, support, agents, merchants, what never to do — is VISION.md.

Open KaChat from this site

KaChat is a mobile app. It does not support PC.

kachat.org has no Apple App Site Association file, so Universal Links on that domain cannot open the app. The custom scheme is what works on a phone. Android does not accept a bare kachat:// with no host.
