Interlay and Kintsugi are being wound down and will stop producing blocks on 22 July 2026.
Users should withdraw their assets from these chains before that deadline. Additionally, if you hold Interlay/Kintsugi assets such as iBTC on other parachains, for example, on Hydration, you should XCM these assets back to those chains and withdraw the corresponding BTC, etc.
Please review the post from the Interlay team below.

The Polkadot mobile app.
It seems that you can get some nice screenshots of the new Polkadot t3rminal / W3S Pay from these newly public repos, if you ask your AI friend nice enough.
These are the "merchant/terminal" part β i.e. what a vendor sets up when you are purchasing something from them.

How it works
A smart contract on Asset Hub holds the offer book, the handoff-agent registry, and the escrow that locks a seller's tokens until both sides confirm β or a 24-hour timeout refunds them.
Bulk data (listing details, profile photos, handover videos) lives on the Bulletin Chain, addressed by content hash (CID).
Trade requests, accept/decline, and meetup coordination travel over the Statement Store β Polkadot's decentralized messaging, not an open chat.
No "connect wallet" button β the app is a Product that runs inside a Polkadot Host (the desktop app or dot.li), which lends it the signer.
Two ways to trade: direct (two people meet) or agent-mediated (a local shop confirms the cash handover).

New today:
- t3rminal β β The real T3RMINAL / W3S Pay repo went public (previously only the -OS-test POC was). This is a heavy-hitter off the still-private list β the POS/payments app (static Next.js β .dot, pallet-revive contract, Bulletin metadata). So W3S Pay is now fully open, and with it the client side of the Coinage flow.
- festival β Brand-new repo, and notably not on the open-sourcing map (repos.csv is unchanged β this one isn't tracked there). "Web3 Festival management prototype": on-chain soulbound tickets, attendance POAPs, and composable unconference-style sessions. Full stack β Solidity contracts (Festival, FestivalSession, AttendancePOAP), separate admin (desktop)
- host-api-test-sdk β Flipped public (was π on the map). @parity/host-api-test-sdk β a thin test host for E2E-testing embedded Polkadot dapps, published to npm.

Disclaimer once again, this is all from public repos, I have no idea what I am doing, I just ask Claude to show me stuff and this is the output π€·ββοΈ
Disclaimer number 2 β this is probably not a final product, WIP, whatever, so don't take it as gospel that this is what shit looks like, ta.

This is the merchant/terminal half. Actual settlement needs a customer's Polkadot mobile host paying in Coinage β that side I can't reproduce here (mobile app still private). The "Environment is not correct" / "1 Issue" are artifacts of the stand-in account, not real bugs.

Even more Polkadot stuff has been made public.
Make sure you read yesterday's thread to find out more about "W3S Coin" - a UTXO-like, privacy-preserving bearer-cash system :)
Asked my AI friend to check for any updates again.
Here's some new Polkadot-related stuff in PUBLIC repos.

Our statement on the UK governmentβs demand that all content on all devices sold or used in the country be scanned, on the presumption of nudity, using a dystopian combination of age verification and content scanning. This proposal will not safeguard children. It endangers us all.

If you spend more than 10 seconds on this you can find even more stuff β my Claude found something called "W3S Coin" and I asked it to find me more info about it.
It looks like some private transfer system, pretty cool.
Yes β quite a lot, actually. "W3S Coin" isn't a repo (repo: null, w3f: true = internally W3F-deployed). It's the Web3 Summit deployment of "Coinage" β Polkadot's private, bearer "cash" payment system. Here's everything I pulled from public code/docs:
What Coinage is
A UTXO-like, privacy-preserving bearer-cash system where a coin literally is an sr25519 secret key:
- Transfers happen off-chain via private-key handoff β whoever holds the secret holds the value (cash-like). Coins can be "spent" or "sniped" (someone else claims first).
- Privacy: uses ring-VRF proofs; cashing out to external accounts needs "matured recycler vouchers"; secrets are transmitted over the Statement Store, encrypted with ECIES / ephemeral P-256 keys.
- Firewalled from products β apps never see coin secrets; the host/user-agent owns all key material.
- Core objects: Purse (balance container), Receivable (pubkey identifying a payment), Cheque (encrypted coin-secret transfer), Invoice (channel receivable amount β QR/deep-link). Settlement is asynchronous.
Where it lives (all public)
- Spec: public HackMD β "Sample Coinage API" β
hackmd.io/@polkadot/coinage-β¦
- RFCs in paritytech/truapi/docs/rfcs/: 0006-payments (Payment Host API), 0017-coinage-payment (the Coinage UA API), 0021-payment-topup-coins (adds a Coins{ sr25519_secret_keys } top-up variant, authored 2026-05-29, motivated by a polkadot-app-android-v2 issue), plus payment-topup-sr25519.md. Rust impl: truapi/.../coin_payment.rs.
- Client implementation: t3rminal-OS-test/lib/payments/coinage/* (the W3S Pay POS POC).
The concrete "W3S Pay" mechanics
- Pay deep-link: polkadotapp://pay/cheque?id=<id>&amount=<amount>&key=<base64url P-256 pubkey>&name=<recipient>
- Max amount 10000, 2 decimal places β i.e. fiat-style denominations. This is effectively a festival cashless-payment system (think wristband/top-up cash at an event), settled in private bearer coins.
- Native handler is W3sPayDeepLinkHandler (Android PR #757); original spec scheme was polkadotapp://w3spay.dot/pay-w3s.
- This is the "CASH" the game-results-webview prize draw pays out, and the balance t3rminal/W3S Pay tops up.
Why it's a "Mobile Review Prerequisite"
It sits in lane 7 with that exact label β meaning the mobile wallet must support the coin-purse before the apps can pass app-store review. So Coinage support is gating the iOS/Android v2 releases.
One thing that's not the coin (easy to conflate)
contracts-boilerplate/.../w3s/W3S.sol is the Web3 Summit 2026 Ticketing contract (ERC721: Standard/Staff/Free tickets, multi-token USDC/DOT deposits refunds, W3F/VOLUNTEER roles, Merkle whitelists) β related summit infra, but separate from Coinage.
Bigger picture: this slots right into the privacy theme (browse = "home for privacy apps", bcts = privacy crypto) β Coinage is private bearer cash for the summit.
