Crypto’s Big Stage: Humans vs AI in Dubai’s WSCT Final
Hash Hedge and AI trading platform Walbi have teamed up to launch the World Series of Crypto Trading (WSCT), the first global crypto trading tournament. Traders from around the world will compete under equal conditions, with eight finalists selected by 20 October. The finalists will go to Dubai, all expenses paid, to battle it out live on 28-29 October during Blockchain Life 2025.
The big twist? Human traders won’t face each other, but also three AI-powered strategies from Walbi, nicknamed the “ChatGPT of trading.” The winner will take home a WSCT bracelet, a cash prize, and a funded trading account from Hash Hedge. Much like poker once created international stars, WSCT aims to crown the first legends of crypto trading.

Noah AI Brings Instant App Building to Solana
Noah AI is a no-code builder that makes creating apps on Solana as easy as sending a message. Instead of learning complex coding, such as Rust or paying developers, you can describe your idea in plain English. In addition, you have a live, production-ready dApp on Solana within seconds.
Solana is one of the fastest and cheapest blockchains, handling over 100 million transactions daily. Nevertheless, barriers, such as high costs, slow audits, and steep learning curves, have held builders back. Noah AI removes these roadblocks by automatically generating contracts, wiring in trusted integrations in Raydium, Jupiter, CoinGecko, deBridge, and Metaplex. You can also deploy your apps directly to the mainnet with built-in security audits.
If you’re launching an exchange or NFT collection, Noah AI helps you turn your ideas into real Web3 projects with no coding needed.
Hydration Unveils HOLLAR: Polkadot’s First Native Stablecoin
Hydration has launched HOLLAR, a new decentralised stablecoin on Polkadot. This coin can accomplish its vision of a full DeFi ecosystem with trading, lending, and stable value all in one place. Unlike centralised coins such as USDC or fragile algorithmic models, HOLLAR is designed to be resilient, fast, and reliable.
Backed by major assets like DOT, ETH, and BTC, HOLLAR uses a unique Stability Module. It provides real-time price support while generating yield, keeping its peg secure. It also introduces smarter liquidations, protecting users with partial interventions instead of wiping out entire positions. From day one, users can mint HOLLAR with collateral at a 5% borrow rate, while low fees and strong downside protection support trading.
Launching with a capped supply of 2 million, HOLLAR is set to become Polkadot’s go-to stablecoin, bringing security, efficiency, and innovation to DeFi.
Tea-Fi Powers One-Third of Katana Users with Reward-Driven DeFi
Tea-Fi is a DeFi platform focused on making crypto simple and rewarding. It has also quickly become the top driver of activity on Katana, a Layer 2 network for decentralised finance. Tea-Fi already accounts for one-third of Katana’s users, showing the strong demand for reward-based engagement in DeFi.
Instead of relying on short-term token incentives, Tea-Fi rewards real on-chain actions like swaps, vault deposits, and dApp interactions. At the core is the TeaPOT, a treasury powered by revenue from swaps, vaults, wallet fees, and payments. This treasury funds TEA token buybacks, continuous user rewards through TeaDrops, and future ecosystem growth.
By keeping assets productive and rewarding genuine activity, Tea-Fi and Katana create a unified approach to sustainable DeFi. Campaigns, such as TeaParty, which doubles user rewards, highlight how activity directly turns into value. With SDKs and APIs, Tea-Fi is also building a composable future where rewards flow seamlessly across apps.

Republic Crypto designed ATTX for long-term sustainability with team token locks, ongoing airdrops, and decentralised governance. By aligning growth with community rewards, Antarctic Exchange is creating a model where traders own the exchange.
