Cross-chain & Private Swaps

The Crypto Swap feature lets you exchange one token for another directly from your wallet. Sumex automatically finds the most efficient route across supported networks, liquidity pools, and bridge providers.

Instead of relying on a single exchange, Sumex aggregates multiple sources and executes the swap through the best available path at the time of the transaction.

How Swap Works​

When you create a swap, Sumex analyzes available liquidity across integrated protocols and builds an optimized execution route.

Depending on the selected tokens and networks, the swap may include:

  • A direct swap within a single liquidity pool
  • A multi-hop route across several pools
  • A cross-chain transaction using a bridge

All steps are combined into a single flow, so you don’t need to manage them manually.

Key Features​

Liquidity Aggregation​

Sumex scans multiple DEXs and liquidity pools to find the best available price and execution conditions.

Smart Routing​

The system builds an optimized execution path that may include multiple steps to reduce cost and improve execution.

Cross-Chain Execution​

You can cryptocurrency swap assets across different blockchains without manually bridging funds.

Non-Custodial​

All swaps are executed directly from your wallet. Sumex does not hold your assets.

Private Swaps​

Ability to opt for Private swaps to minimize your on-chain history exposure and increase privacy of cross-chain swap transactions.

How to Make a Swap​

  1. Connect Your Wallet Use a supported wallet to access the Swap interface.

  2. Select Tokens Choose the token you want to swap and the token you want to receive.

  3. Select Networks For cross-chain swaps, choose the source and destination networks.

  4. Enter the Amount The interface will display the estimated output.

  5. Review the Route Before confirming, review:

  • Estimated output
  • Execution route
  • Fees
  • Price impact

  1. Adjust Settings (Optional) You can set slippage tolerance if needed.

  2. Confirm the Transaction Approve the swap in your wallet.

Privite Swaps​

Private Swaps are a transaction execution mode designed to reduce the exposure of swap activity to the public mempool before confirmation. In traditional on-chain swaps, pending transactions can often be visible before they are finalized, which may expose traders to risks such as frontrunning, sandwich attacks, MEV exploitation, and unnecessary slippage caused by bots reacting to visible orders.

Private Swap infrastructure helps route transactions through more protected execution channels, reducing visibility before settlement and improving execution quality in certain market conditions. This can be particularly useful for traders executing large orders, volatile asset swaps, cross-chain operations, or transactions where minimizing market impact and preserving execution privacy is important.

Rewards and Progression​

Each swap on Sumex earns rewards as part of the platform’s gamified ecosystem.

Users receive XP for activity, helping them level up their profile and progress within the ecosystem via the Rewards Hub.

Swaps also generate Sigma Points (SP), designed to be convertible into tokens after the Token Generation Event (TGE). You can track progression on the Leaderboard.

Reward amounts depend on transaction parameters such as:

  • Trade size
  • Route complexity
  • Network conditions

Rewards are integrated into the broader Complete & Earn system, allowing users to gain experience, explore new tools, and unlock additional opportunities while interacting with the platform.

Pricing, Slippage, and Price Impact​

The final amount you receive depends on:

  • Available liquidity
  • Trade size
  • Market conditions

Slippage​

Slippage is the difference between the expected and actual execution price.

Price Impact​

Price impact reflects how your trade affects the pool price, especially for larger orders.

If liquidity is low or the market is volatile, the result may differ from the estimate.

Fees​

Swap transactions may include:

  • Network (gas) fees
  • Liquidity provider fees
  • Bridge fees for cross-chain swaps

All costs are displayed before confirmation.

Execution and Routing Behavior​

Simple swaps within the same network are usually completed in a single transaction.

More complex swaps may:

  • Use multiple liquidity pools
  • Include intermediate tokens
  • Involve cross-chain bridging

In such cases, execution may take longer and depend on external protocols.

Edge Cases and Limitations​

No Route Available​

If sufficient liquidity is not found, the swap cannot be executed.

Transaction Delays​

Network congestion or bridge processing may increase execution time.

Partial Failures​

In rare cases, a route may fail due to external protocol conditions.

Price Changes​

Market movement during execution may affect the final output.

Important​

Sumex is a non-custodial platform. You remain in control of your funds at all times.

Always review transaction details before confirming.

FAQ​

What is the best way to swap crypto?​

Using an aggregator like Sumex helps optimize routing and improve execution across multiple liquidity sources.

Can you swap cryptocurrency directly?​

Yes. You can exchange one token for another directly without converting to fiat.

Is it cheaper to swap or sell crypto?​

Swapping is often more efficient within crypto ecosystems, especially when routing reduces fees and price impact.

Is swapping crypto safe?​

Swapping is generally safe when using non-custodial platforms, but risks such as smart contract vulnerabilities and market volatility still apply.

What is a Private Swap?​

A Private Swap is a transaction execution method that reduces public exposure of swap activity before confirmation, helping lower risks related to MEV, frontrunning, and sandwich attacks, while increasing privacy of personal data.

Who are Private Swaps useful for?​

Private Swaps are useful for traders handling larger transactions, volatile assets, low-liquidity tokens, or users who want additional transaction protection and reduced market visibility.

Do Private Swaps make transactions completely anonymous?​

Yes, but to a high degree. While the mechanics of Private Swaps can't erase all on-chain history, most of the routes can disrupt the direct link between the sender and recepient addresses via bridging on privicy chains or the use of CEX-based liquidity.

Can Private Swaps improve pricing?​

In some situations, yes. By reducing exposure to MEV bots and frontrunning activity, Private Swaps may help reduce slippage and improve execution efficiency during volatile market conditions.

Why do I lose money when swapping crypto?​

Losses may occur due to slippage, fees, price impact, or rapid market changes during execution.

Does Swap require KYC?​

No. Swap transactions are executed directly from your connected wallet and do not require KYC verification. Sumex is a non-custodial platform and does not take custody of user funds during execution.
