How Uniswap Swaps Work​

  1. Select tokens — Choose from the curated top-100 list or search for any token
  2. Enter amount — Type the amount to swap or use quick buttons (Max, 50%, 25%)
  3. Review quote — See price impact, route details, and fee breakdown
  4. Approve token (first time only) — Confirm the approval with clear risk information
  5. Execute swap — Sign and submit via UniswapX or Classic routing
  6. Track status — Real-time status updates until confirmation

Fee Structure​

  • SuperSafe Fee: 0.2%
  • Uniswap Labs Fee: 0.2%
  • Total: 0.4%
Approval Confirmation

When approving a token for the first time, SuperSafe shows a detailed confirmation screen explaining what "Approve" means, the spender address, and any unlimited approval warnings. This protects you from unknowingly granting excessive permissions.

🔗 Relay.link (Cross-Chain)​

The go-to provider for cross-chain swaps and bridging — swap tokens between different networks in a single transaction.

Key Features​

  • Cross-Chain Swaps: Swap tokens across different networks in one step
  • 85+ Blockchains: Wide network support including all SuperSafe networks
  • Meta-Aggregation: Best prices from multiple DEXs and bridges combined
  • Route Visualization: See the step-by-step execution path (bridge, swap, approval)
  • Bridge Time Estimation: Dynamic completion time based on network congestion
  • Gas Estimation: Real-time gas cost display per step and total

How Relay Swaps Work​

  1. Select origin token — Uses your active network (switch network via the header to change)
  2. Select destination — Choose the destination network and token
  3. Enter amount — Specify how much to swap
  4. Review route — See the multi-step route visualization (bridge + swap hops)
  5. Execute swap — Approve and submit the cross-chain transaction
  6. Track bridging — Follow real-time status with estimated completion time

Fee Structure​

  • SuperSafe Partner Fee: 0.4%
  • Total: 0.4%
Network Selection

The origin (Pay) network is always your currently active network. To swap from a different network, switch your active network first via the header. This ensures balances are always accurate and transactions can be properly signed.

🐝 Bebop (Gasless)​

The original SuperSafe swap provider — completely gasless swaps via the Bebop JAM (Just Another Market) protocol with built-in MEV protection.

Key Features​

  • Gasless Swaps: Zero gas fees via Permit2 — you only pay for the one-time token approval
  • MEV Protection: Private mempool protects from sandwich attacks and frontrunning
  • EIP-712 Signing: Orders are signed, not sent as transactions — no gas consumed
  • Best Price: Aggregated liquidity from multiple professional market makers
  • Single Approval: One-time Permit2 approval covers all future swaps for that token

How Bebop Swaps Work​

  1. Select tokens — Choose from and to tokens
  2. Enter amount — Specify the amount to swap
  3. Review quote — See price impact, route, and fee breakdown
  4. Approve token (first time only) — One-time Permit2 approval (gas required)
  5. Sign order — Sign the EIP-712 typed data (no gas!)
  6. Order executes — Bebop settles the order on-chain

Fee Structure​

  • SuperSafe Partner Fee: 0.4%
  • Total: 0.4%
Why Gasless?

Bebop uses Permit2 + EIP-712 signing, which means your swap doesn't require an on-chain transaction from you. The market maker settles the trade, so you pay zero gas for the swap itself. You only pay gas once per token for the initial Permit2 approval.

⛽ Gas Validation System​

SuperSafe protects every swap with real-time gas validation:

  • Scam Detection: Blocks transactions with gas > 50% of swap value
  • Balance Validation: Ensures sufficient native tokens for gas
  • Real-time Monitoring: Fetches current network gas prices
  • Button-Integrated Alerts: Visual feedback directly on the swap button

See Gas Validation System for full details.

🛡️ Price Deviation Alerts​

  • > 5% deviation: High alert — "Unfavorable quote" warning
  • > 2% deviation: Moderate alert — caution indicator
  • < 2% deviation: Normal — no alerts

Troubleshooting​

Common Issues​

IssueLikely CauseSolution
Swap button disabledInsufficient gas balanceAdd native tokens (ETH, BNB, etc.)
"Gas Fee Too High" warningPossible scam contractVerify the token contract before proceeding
High price impactLarge amount or low liquidityReduce amount or wait for more liquidity
Approval failedInsufficient gasEnsure enough native tokens for the approval transaction
Slippage exceededMarket moved during swapIncrease slippage tolerance and retry
Cross-chain swap slowBridge congestionCheck the estimated bridge time in Relay panel

Choosing the Right Provider​

  • Standard swaps (ETH ↔ USDC, etc.): Use Uniswap for best routing and token coverage
  • Cross-chain transfers: Use Relay.link to swap + bridge in one step
  • Gas-free swaps: Use Bebop for zero-gas swaps on supported networks

Best Practices​

  • Compare providers — Check quotes across providers for best price
  • Start with small amounts — Test new token pairs with small swaps first
  • Watch slippage — Use 0.5% for stable pairs, higher for volatile tokens
  • Check gas alerts — If the swap button shows a warning, investigate before proceeding
  • Verify tokens — Always confirm the token contract address, especially for new tokens
