Operating smoothly on the $TON blockchain requires strict control over the types of assets made available for trading. A major consideration is how tokens behave during execution, especially those that apply automatic fees or transfer taxes. These so called tax tokens reduce the final amount received compared to the quoted estimate, creating inconsistencies for traders. To preserve reliability and transparency, such assets are generally excluded from the core interface of STONfi.

Because these embedded fees are written directly into a token’s smart contract, they cannot be adjusted by external platforms. The absence of a standardized framework for handling them introduces uncertainty, particularly in multi step routing where a swap moves across several liquidity pools. In these scenarios, taxed assets may interrupt the transaction flow or cause inaccurate output calculations. By prioritizing tokens with stable and predictable mechanics, the protocol ensures that users receive outcomes that accurately reflect their quoted expectations.

Beyond asset filtering, STONfi implements specialized execution frameworks to support more complex instruments. Escrow-based swaps are used for structured assets such as xStocks, enabling trustless transactions through solver-provided pricing. This mechanism connects to OTC liquidity and guarantees that trades are executed only if all predefined conditions are satisfied. The result is an atomic settlement process designed to meet higher security and performance standards for advanced token classes on the $TON network.

Applying disciplined listing criteria is fundamental to maintaining a dependable decentralized ecosystem. Clear rules around asset eligibility strengthen trust, reduce operational risk, and enhance overall network efficiency. When participants interact with tokens that behave consistently and transparently, the trading environment becomes significantly more stable. This structured and security-focused approach allows STONfi to expand supported digital assets responsibly while ensuring that every transaction on the $TON blockchain remains reliable, transparent, and professionally managed.
