Ensuring a predictable and safe experience on the TON blockchain depends heavily on the quality of the assets available for swaps. One specific area of focus is the management of tokens that include built-in fees or taxes on every operation. These tax tokens can lead to unexpected results because the final amount received by a participant is often lower than the initial quote. To maintain high standards, such assets are typically excluded from the primary interface of STONfi. ──── ᧓. ✿ .᧔ ──── These built-in costs are hardcoded into the token's logic, and without a unified technical standard, they can cause significant issues for automated swap systems. In complex routing where a swap passes through multiple pools, these assets can sometimes become stuck or result in failed operations. By focusing on tokens with clear and predictable behavior, the platform ensures that the final outcome of an exchange matches the parameters set by the smart contracts. ──── ᧓. ✿ .᧔ ──── In addition to filtering these assets, the protocol uses advanced execution models like escrow swaps for more specialized tokens. This is the case for xStocks, where a trustless mechanism allows for direct exchanges based on prices provided by professional solvers. This system taps into OTC liquidity and ensures that the operation is only completed if all conditions are met. This provides a high level of security and institutional quality for specialized assets on the TON network. ──── ᧓. ✿ .᧔ ──── Maintaining strict listing policies is a necessary part of building a professional and reliable decentralized environment. When users can trust the data and assets they interact with, the entire network becomes more functional. This disciplined approach to asset quality is what allows the platform to support a wide variety of digital holdings while keeping the experience secure and transparent for everyone involved in the TON ecosystem. $NEAR
