STON.fi brings seamless self-custodial DeFi to US Telegram users TOP portfolio project STON.fi, the leading swap decentralized app and protocol suite on TON Blockchain, now enables users in the US to easily swap digital assets within TON Wallet — a self-custodial crypto wallet built into Telegram. Nearly 87 million US Telegram users can access STON.fi through TON Wallet or the standalone STON.fi app. STON.fi powers swaps using Omniston, a decentralized system that connects multiple liquidity sources to ensure users get the best rates without the usual complexity of crypto trading. This launch marks a key milestone in making decentralized finance accessible to everyday users in the US, expanding the TON ecosystem and enabling people to manage digital assets securely and conveniently. "This integration represents a significant step toward mainstream cryptocurrency adoption. By bringing swapping services directly into one of the most widely adopted TON wallets, we’re removing the traditional friction points that have long kept everyday users from accessing decentralized finance. Users can now use crypto as easily as sending a message."  – Slavik Baranov, CEO of STON.fi Dev.

Stablecoins are not yet widely used to support real economic activities – such as for payments. However, stablecoin issuers are becoming significant players in traditional financial markets. Their substantial reserve holdings are now comparable to those from foreign governments or large money market funds. The concentration of holdings among a few stablecoin issuers raises concerns about potential market disruptions during periods of stress. Stablecoin issuers may be forced to liquidate reserves rapidly to meet redemption requests. For these reasons, it is important to closely monitor developments and have robust regulatory safeguards in place, especially given stablecoins’ growing use cases (particularly in emerging market and developing economies), the potential for bank disintermediation, and risks that may arise from certain business models that issue stablecoins across multiple jurisdictions and may need to manage reserves across borders. Read more about the financial stability implications of the rise of stablecoins as well as about the implementation of a regulatory framework in our report: https://bit.ly/4n8pNDU #Stablecoin #Crypto #Payments #Treasuries #EMDE #EmergingMarkets #BankDisintermediation
