# How KaChat could use PegLab — and what “real” means KaChat ([kachat.org](https://www.kachat.org/), [vsmirn0v/KaChat](https://github.com/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. PegLab’s idea is that unit: a Kaspa-native alternative to USDT/USDC so a dapp can invoice, escrow, and tip **on Kaspa**, not on Circle. **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. KaChat should not ship that. --- ## What KaChat is today | Piece | Today | | --- | --- | | Chat | E2E payloads on L1 (`kchat:1:comm`, groups, KaPosts) | | Pay | Native **KAS** to a recipient, optional encrypted memo | | Timeout pay | Sketch already exists: `KaChatPayTimeout.sil` — recipient claims now, sender reclaims after `tx.time` | | Identity | KNS names; aliases are not consensus uniqueness | | Fees | Every message and pay still burns **KAS mass** | | FX | Portfolio uses CoinGecko; the payment itself is still sompi | 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 unit, pay in the unit** “20 tPEG for the logo” stays 20 until paid or the timeout fires. The thread is the invoice. 2. **Pay with timeout (compose, don’t rewrite chat)** Lock the unit in a covenant. Recipient claims. If they ghost, sender reclaims after timeout. That is `KaChatPayTimeout` with PegLab UNIT as the asset instead of raw KAS. 3. **Group split / tip / chess stake** Same covenant family: lock, split, release, or refund. Chat is coordination; L1 is the court. 4. **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. 5. **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) | Unit | First sentence in KaChat | PegLab role | | --- | --- | --- | | **A. KAS receipt** | “This is locked tKAS. The number is sompi, not USD.” | Productionise receipt/covenant transfer + redeem. No oracle. Closest to `backed-receipt` + PegLab UNIT transfer. | | **B. Hosted USD** | “This is USDC/USDT from *named issuer*. Freeze risk is theirs.” | PegLab is not the issuer. KaChat lists a foreign asset when it exists on Kaspa. | | **C. Fake $1 tPEG** | Do not ship. | This lab only. Admin oracle + 2 tKAS pool. | **Default for KaChat: A now, B when a real dollar is on Kaspa.** C stays the public depeg demo so nobody “just lists tPEG.” Work credits / grams (`WorkCredit.sil`) are a **fee voucher** (KIP-21 mass), not a chat dollar. Useful so messages have prepaid grams. Different button from “pay the designer.” --- ## What must be built to make A real Order matters. Skipping to mainnet chat-pay is how you mint a bridge IOU. ### 1. PegLab (or receipt) on Testnet-10 for real - Broadcast genesis, mint, transfer, redeem — not only the JS engine. - Pin series / genesis outpoint / template hash. Wallets verify those, not the word “tPEG”. - Kill the admin USD oracle for the KaChat asset. Receipts do not need a dollar feed. - Indexer (or KaChat’s Kasia indexer) must see UNIT UTXOs and balances by address. ### 2. A wallet KaChat already is KaChat is a Swift wallet (Secure Enclave, node pool, UTXO subscribe). KasWare-on-the-web is not enough. - Sign covenant spends (`act` / transfer / redeem) from the iOS/desktop wallet. - Show UNIT balance next to KAS. - Refuse unknown series. A cloned ticker is not funds. ### 3. Chat protocol Extend pay, do not invent a second messenger: - Keep `kchat:1:pay` for KAS. - Add something like `kchat:1:payunit` (or a typed field): series id, covenant id, amount, timeout, memo ciphertext. - Handshake still E2E. Payment still a recipient-addressed (or covenant) tx the recipient’s watcher can see. - Timeout reclaim uses the same idea as `KaChatPayTimeout.sil`. ### 4. Fees (“who pays the KAS”) A “dollar-shaped” pay that first says “go get KAS for mass” is dead UX. - Sponsor-fee input on the pay tx, or - Prepaid **grams** (WorkCredit) consumed when sending chat+pay, - UI: user thinks in the unit; KAS is the postage. ### 5. Product copy in the app - Asset picker: KAS | PegLab receipt | (later) named USD. - No `$` 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 | Step | Where | Done when | | --- | --- | --- | | 0 | PegLab lab | People can run the depeg demo and read this file | | 1 | PegLab TN10 | One live series, transfer+redeem accepted on Testnet-10, indexer row | | 2 | KaChat testnet | Wallet shows that series balance; send 1 unit in a 1:1 chat with timeout | | 3 | Fees | Pay tx does not fail because the receiver has 0 KAS | | 4 | Groups | Split / tip using the same covenant, still testnet | | 5 | Mainnet | Only for **receipt (A)** after audit-lite + KaChat review — still not called USD | | 6 | USD in chat | Only if a **named** USDT/USDC exists on Kaspa | --- ## 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. PegLab is the unit the conversation can settle in without USDT. Real means a receipt (or a hosted real USD), a KaChat signer for that covenant, 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](VISION.md). --- ## Open KaChat from this site KaChat is a mobile app. It does not support PC. | Device | What this site does | | --- | --- | | Windows / macOS / Linux | Shows: **KaChat does not support PC.** No desktop client.
