Swapping tokens in non-custodial wallets such as Tonkeeper gives users a powerful level of control and privacy over their cryptocurrency assets. Tonkeeper is designed to put users in charge, with built-in features for managing Toncoin, USDT, and various tokens on The Open Network (TON). With instant transactions, an extensive dApp ecosystem, and seamless token swaps, it represents the ideals of decentralization and self-custody. However, this empowerment also comes with a greater responsibility for thoroughness. Every click matters—especially when confirming swaps—since any mistake can result in the permanent loss of funds, with no centralized entity to intervene or undo errors.
This article explains the most important safety checks every Tonkeeper user should follow before confirming a token swap. By carefully verifying token identity, reviewing swap fees and confirmation screens, and understanding the concrete risks of DeFi and on-chain swaps, users can make informed decisions and minimize avoidable mistakes.
Inspecting Token Identity and Swap Route
A crucial first step before any swap is to confirm you are interacting with the correct tokens. This may sound simple, but given the diversity and similarity among tokens within the TON ecosystem, it is easy to make errors. Some scammers exploit token similarities—copying names, symbols, or logos—to trick users into swapping for malicious lookalikes. Relying purely on appearance is risky.
Always check the unique token contract address before swapping. The contract address is the definitive identifier for every legitimate token, distinguishing it regardless of its name or symbol. For popular options like Toncoin or USDT, Tonkeeper helps present the correct information, but if you are swapping for a less common asset, you should cross-reference its contract address using official sources or trusted community channels. Do not proceed with a swap if you cannot verify the token’s legitimacy with information provided directly by the project or recognized aggregators.
When considering the swap route, take note of the path your transaction follows. Many swaps use decentralized exchangers or aggregators, which may involve intermediate tokens or multiple hops to facilitate the swap. Hidden or complex routes can introduce extra fees, expose you to unexpected price changes, or even increase vulnerability to malicious actors. Transparency is key: Tonkeeper aims to display clear information, but if the route seems unclear or suspicious, pause and investigate before moving forward. Understanding exactly what you are signing is essential for effective self-custody.

Reviewing Fees and Confirmation Prompts
- The type and amount of token you are offering
- The type and amount of token you will receive
- All network and swap fees (including decentralized exchange fees)
- The contract address of both tokens
- Any slippage setting or margin for price movement
- The wallet address involved in the transaction
Hasty confirmations are a leading cause of accidental losses. If the figures or addresses shown do not align with your expectations or your own external checks, do not proceed. In DeFi, mistakes cannot be reversed, and wallet confirmations represent final, on-chain authorizations.
It is also important to recognize that fees can sometimes be higher than expected due to network congestion, intermediary routing, or volatile liquidity conditions. This is especially true for tokens with smaller pools or newly launched assets—where prices may fluctuate rapidly.
Recognizing Token, Price, and Smart-Contract Risks
Token Risks
Because token contracts can be freely created on blockchains like TON, there is potential for counterfeit, cloned, or otherwise malicious smart contracts. Swapping for a token with the correct name but a fraudulent contract address can result in receiving an asset with no real value or, worse, an exploit embedded within the contract. Always treat contract addresses as unique fingerprints for tokens.
Price and Execution Risks
On-chain swaps are subject to rapid market changes and execution quirks. The final execution price may differ from what was previewed, especially during periods of volatility or when operating with tokens that lack deep liquidity. This difference is called slippage, and if set too loosely, it could result in significant loss. Carefully monitor all price outputs, and use conservative slippage settings when possible.
Smart Contract Risks
Interacting with smart contracts is fundamental to decentralized swapping, but it brings exposure to technical bugs and security vulnerabilities. Even established protocols can encounter unforeseen issues, as DeFi is a fast-moving field. Avoid connecting to third-party dApps or entering into complex swaps unless you trust the application and it has received some community scrutiny or security review. If unsure, seek advice from more experienced users or the broader TON community.
