cbBTC and Bitcoin Liquidity on TON
Bringing Bitcoin liquidity to TON opens new possibilities for DeFi.
On STONfi, cbBTC is a tokenized representation of Bitcoin on The Open Network. It allows BTC holders to use their assets directly within TON-based protocols without leaving the blockchain.
The process starts with wrapping Bitcoin into cbBTC through a secure bridge. Once converted, cbBTC can be transferred, swapped, or added to liquidity pools within TON’s DeFi ecosystem.
Liquidity pools using cbBTC enable trading pairs, yield farming, and decentralized lending. Users provide cbBTC alongside other tokens, earning rewards while increasing market depth. The more participants contribute, the more efficient and liquid the ecosystem becomes.
This setup creates a seamless link between Bitcoin and TON DeFi. It combines the security of BTC with the flexibility of TON’s smart contracts, giving users exposure to BTC while participating in decentralized finance.
On STONfi, cbBTC strengthens liquidity, supports trading, and expands DeFi opportunities on The Open Network.

Polymarket Opens a New Era with Polymarket USD and CTF Exchange V2
Polymarket, the world's largest prediction market platform, announced a major infrastructure upgrade on April 6, 2026. This initiative focuses on launching its native collateral asset, Polymarket USD, marking a profound shift in the platform's trading architecture. By reducing reliance on wrapped assets and building a more institutionally compatible, vertically integrated system, this upgrade represents the beginning of a new phase in expanding decentralized prediction markets.
Polymarket USD is designed as a collateral token backed 1:1 by USDC issued directly by the platform. It will replace the USDC.e version(linked via bridge), which connects USDC across Polygon, eliminating third-party bridge risks and providing a more secure and consistent settlement standard. Rather than being a tradable or speculative asset, Polymarket USD functions as a wrapped stablecoin specifically tailored for the platform. For most users, the transition will be seamless, as the frontend automatically handles wrapping through a one-time approval request. Advanced users and API traders will have the option to convert USDC or USDC.e directly via a smart contract for Polymarket’s collateral entry point. This shift not only enhances the platform’s control over liquidity but also opens potential opportunities for new yields and revenue streams.
At the core of the upgrade is a new smart contract system for CTF Exchange V2. This is a complete rebuild of the trading engine based on a hybrid centralized order book architecture (CLOB) — combining off-chain order matching with on-chain settlement. Order structures have been simplified, matching logic accelerated, and verification steps reduced. As a result, gas fees are expected to decrease significantly, execution speeds to increase, and spreads to narrow. These improvements are essential for efficiently handling the trading volume Polymarket experienced throughout 2026.
A key feature for institutional participants is the addition of support for EIP-1271. This standard enables direct interaction with the platform for multi-signature wallets, such as Safe, for the first time. Removing this long-standing barrier will greatly facilitate the participation of DAOs, professional funds, and algorithmic trading desks. Other technical enhancements include on-chain customization of orders via build tokens and a redesigned fee collection and distribution mechanism. API users will need to update to the latest version of the CLOB-Client SDK(, available in TypeScript, Python, and Go).
These changes are closely aligned with Polymarket’s broader enterprise growth strategy. Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, completed its investment commitments with a cash infusion of $600 million in March 2026, bringing the total to approximately $2 billion since October 2025. These funds support Polymarket’s readiness for regulated environments—especially the potential expansion in the United States—and its ambition to compete with traditional derivatives exchanges. The partnership with Circle in February 2026 further cemented USDC’s central role on the platform.
The transition will be implemented gradually over the next two to three weeks. All existing order books will undergo a full update, resulting in the cancellation of all open orders and a scheduled short maintenance window. Polymarket has committed to providing at least one week’s notice before maintenance begins, allowing traders sufficient time to manage their positions.
In summary, the launch of Polymarket USD and CTF Exchange V2 marks a strategic evolution for Polymarket from reliance on general DeFi components to building a vertically integrated financial powerhouse. By reducing bridge risks, lowering transaction costs, enhancing institutional access, and gaining full control over liquidity layers, Polymarket elevates prediction markets to a more professional and scalable level. This development represents a significant milestone in integrating the industry with mainstream finance.
