Our CEO joined the TxPipe Pyth Network 🔮 Input Output Group Hackathon to show what Cardano can do. We built a Polymarket-style 5-min BTC prediction market — fully on-chain with Aiken smart contracts + Pyth Lazer oracle verification. Bet YES/NO, claim winnings, all verifiable on-chain. The pieces are falling...

Self Disclosure Privacy using ZK Proofs, Demonstrated & Executed Directly on Cardano Preview I built a demo where a customer buys a beer and proves they are 18 or over, without ever showing their ID. No name. No birth year. No photo. Just maths. Two beers were ordered. Two separate transactions. The same proof, reused, no re-verification needed. The blockchain recorded "age verified" both times. That's all it knows. No name. No address. No date of birth. No photo. No personal data of any kind. This runs entirely and directly on Cardano. No sidechains. No L2s. No off-chain verification. The ZK proof is checked by the Plutus V3 validator itself, on-chain, using Groth16. And this isn't just for bars, it works for shops, website signups, any age-restricted service. One credential, reused anywhere. Self disclosure means you choose what to share, and in this case, the customer chose to share nothing except "yes, I'm old enough, give me a nice cold beer." 🍺 Massive shout out to everybody involved in the below! Aiken smart contract language on Cardano (please don't judge my Aiken... I know it's bad 😂) ak-381 by Modulo-P, Groth16 SNARK verification library for BLS12-381 on Aiken Circom + snarkjs, ZK circuit design and proof generation MeshSDK, transaction building and wallet management Blockfrost, blockchain data provider A basic demo to set the stage for further privacy enhancements that can occur directly on Cardano. Self disclosure privacy on Cardano Cheers Cardano 🍻🍻 Beer 1 Beer 2

I vibe-coded a bot for the 5M / 15M BTC markets on Polymarket. Releasing it for you for free. Open source (Python). I just earned $400 today on Polymarket with this tool myself It doesn’t trade It just prints a signal in the console: UP or DOWN 🔸 The signal appears a few seconds before the Polymarket market actually moves. The bot exploits a Chainlink oracle inefficiency. What matters is that it consistently gives you a 4-8 second lead over the actual quotes on Polymarket. In practice, you’re seeing a few seconds into the future. What you can do with it: 🔸 Possible strategies: 1/ Momentum sniper Bot gives a signal -> instant entry into the current 5-minute market in the direction of the signal (Yes/No). Works best during strong moves >0.3-0.5%. 2/ Last-second scalp before market expiration 3-12 seconds before the 5-minute candle closes, you already see where the BTC candle is going to close. -> Enter Polymarket at the very last moment. 3/ Hedging + arbitrage Strong signal against the current Yes/No price -> hedge your position or catch crowd squeezes. Especially juicy in the final seconds, when odds are still fat, but the outcome is almost decided. 🔸 This is pure price update inefficiency. Open the 5M or 15M BTC market yourself. Run the bot. Watch who moves first. Until this gets tightened up - it’s a clean inefficiency. And yes, if you ape your entire deposit into it, the market will punish you fast. 🔸 But as a tool - this is the closest thing to a "Polymarket money printer" setup I’ve seen recently. Python bot setup instructions on GitHub: DYOR. Print hard, print smart.

🚨 we’re back with the superteam india podcast! we’ve all heard of prediction markets but how do prediction markets with precision look like? on the first episode back, this episode of the superteam india podcast, Harkirat Singh sits down with Anam, blockchain engineer at Trepa — a precision prediction market built on solana (Colosseum hackathon winners by the way) where you don’t just bet yes or no, you predict exact numbers and get rewarded based on accuracy. we go deep into the technical architecture: why they store predictions in logs instead of on-chain, how rpc providers can silently truncate your program logs at 12kb, the emit cpi fix that saved them, why they rebuilt v1 from scratch over missing reserved bytes in their pdas, and the real cost challenges of sponsoring gas fees for a consumer app on solana. ⏱️ timestamps: 00:00 - cold open 00:38 - intro & guest welcome 01:08 - anam’s journey: mlh fellow → solana foundation → helius → trepa 03:04 - working at solana foundation & helius 04:20 - what are precision prediction markets? 05:03 - trepa vs polymarket: how payouts work 06:05 - the three factors: accuracy, stake & time 06:56 - what if no one else joins the pool? 08:09 - liquidity & market making challenges 09:17 - how prediction precision & steps work 10:37 - why they rebuilt v1 → v2 (reserved bytes) 12:28 - onchain storage optimization & rent reclaim 13:39 - security audit with adware labs 15:12 - the 12kb rpc log truncation discovery 15:59 - emit cpi fix: storing data as instruction data 16:33 - on-chain vs off-chain architecture deep dive 17:17 - why trepa sponsors gas (and the cost implications) 20:45 - top open source solana contracts to learn from 22:12 - what’s next: flash pools (2-minute prediction cycles) 23:38 - team size & hiring at trepa 25:50 - advice for aspiring solana smart contract devs 27:10 - outro

Nasdaq Just Exposed Wallstreets Bet on a Crypto Coin Nobodys Heard Of Nasdaq just put Wall Street's market data on a crypto coin most people have never heard of, and the company that settles almost every US stock trade is quietly moving onto crypto too. I break down which coins these giants picked and why it matters for your money inside our group. Join at the link is also in my bio. Start with Nasdaq. It is now the biggest stock exchange in the world, ahead of the New York Stock Exchange, home to Apple, Microsoft, and Amazon, with over 35 trillion dollars in listed companies. On June 30, 2026, Nasdaq brought its TotalView market data to a small crypto network called Pyth. Pyth became the first on chain network to distribute Nasdaq's data. That coin trades for around 4 cents. Then look at the back end. There is a company called the DTCC that you have probably never heard of. It settles nearly every stock trade in America and its custody just passed 100 trillion dollars. The DTCC set a July pilot and an October 2026 launch to start tokenizing real securities, which means turning stocks and bonds into blockchain tokens. And its blockchain push leans on two coins that have been public for years, Stellar and Chainlink. Stellar is the settlement chain for tokenized assets. Chainlink powers a separate 24/7 collateral system. So the front of the stock market and the back of the stock market are both moving onto crypto rails at the same time, built on coins anyone with an internet connection could already buy. This is not a coin pump. It is the plumbing of the entire market getting rebuilt in plain sight. The only question is whether you see it before everyone else does.

Tonkeeper is now Keeper The best self-custodial wallet on TON now holds assets on $BTC, Ethereum, TRON DAO, Arbitrum, Base, BNB Chain — with more chains landing soon. 77 million downloads and counting. One wallet for everything you own. Tonkeeper was built for one chain and set the standard on it. Crypto stopped being one chain per wallet, and so did we. Keeper brings that standard to every chain we support and the communities that call them home. ● TON is home Jettons, NFTs, staking, DNS, the in-wallet browser. Everything that made Tonkeeper the default on TON is here, untouched. TON is not going anywhere. Neither are we. We are taking it further. $BTC $ETH $USDT $TRX $ARB $BNB and more. One app. ● What multichain gives you One app and one recovery phrase for every account on every network — including every chain we add from here. Why do you need a new wallet instead of just adding networks to the old one? TON uses its own key generation scheme, which isn't compatible with the BIP-39/44 standard that EVM networks and most other wallets run on. That's why a single seed phrase technically can't cover both TON and the other networks. You need a separate wallet with a separate phrase. ● Swaps across chains happen inside the wallet: no bridges, no wrapped tokens, no second app to install. Pick what you have, pick what you want, confirm. Built with our partner MoonPay 🟣 . ● Gas is handled. Battery covers the network fee on TON and TRON, so you never buy a second token just to move the first one. Your USDT on TRON moves with zero TRX in the wallet. Multichain is live in the iOS and Android apps today. Web, desktop and the browser extension get it shortly after. 💙To everyone who has been with us since Tonkeeper Thank you. You've been a huge part of our growth and we want to give something back. 0% fees on cross-chain swaps until September 22, on us. And if you migrate your funds right now, you'll also get tickets toward the mystery raffle. In a week, you'll find out exactly why it was worth hurrying. This is just the beginning More networks. Battery on more chains. The wallet you trusted with one chain is about to run all of them. Be a Keeper Get Keeper:
