The Swap screen: paying ETH and receiving USDT on Ethereum

Trading and moving tokens in one app

Trading a token usually means choosing a DEX without knowing whether its price is competitive. Moving it to another network requires finding a bridge and working out its fees, and every network charges its fee in its own coin.

In FxWallet, Swap gathers quotes from several aggregators and DEXs, and Bridge from several bridges. Both show the route, the fees and the amount to be received before signing, and every transaction is signed with your own keys.

How Swap selects a route

  1. Quotes from multiple sources

    Aggregators and DEXs each quote the trade.

  2. Network fees deducted

    Each quote is compared by the amount received after the network fee.

  3. Best route selected

    The route with the highest net amount is selected.

Why swap and bridge in FxWallet

The highest amount after fees

Swap asks several aggregators and DEXs for quotes, and Bridge several bridges, and ranks them by what you receive after fees. Swap leaves out routes that have been failing, and quotes refresh every 15 seconds.

Failing swaps stopped before you pay

Every Solana swap, and EVM swaps above a set value, are simulated before you sign. If the result would fail or fall far below the quote, FxWallet does not send the swap, and no network fee is spent.

Honeypots and fake tokens refused

Before buying, FxWallet checks the token on the EVM networks GoPlus covers. Honeypots, which can be bought but never sold, fake tokens and airdrop scams are refused, and so is a trade with a very high price impact.

Approve only what the swap needs

For a swap or a bridge transfer, FxWallet approves exactly the amount needed instead of an unlimited allowance, so a contract exploited later cannot reach the rest of your balance.

Bridge transfers tracked to the last step

Each quote shows its estimated time, and the transfer is tracked until it arrives. When the destination network needs one more transaction, as a withdrawal from a layer-2 network to Ethereum does after about a week, the transfer is marked Action Needed.

Swap network fees paid by a Gas Card

On 4 EVM networks, a Gas Card pays the network fee of swaps, approvals included, so a token can be traded on a network where the wallet holds none of its coin. Details are below.

In the app

Inside Swap & Bridge

  • Route comparison

    Swap lists quotes from several aggregators and DEXs, ranked by the amount received after fees, and marks the best route. Quotes refresh every 15 seconds.

  • Costs before confirmation

    Before a swap is confirmed, the details show the minimum amount received, the slippage, the network fee and the FxWallet fee, which is 0% on some routes.

  • Bridge transfer status

    Bridge shows the estimated time and fee of each route. Transfers in progress appear at the top, and a transfer that requires a claim on the destination network is marked Action Needed.

Network fees

Sending without the network’s gas token

Every transaction pays a network fee in the network’s own coin. On some EVM networks, FxWallet offers two ways to pay it without holding that coin.

Gas Card

Prepaid credit for network fees, tied to your wallet. It pays fees on BNB Chain, Polygon, Arbitrum, and Optimism when sending tokens or NFTs, swapping or using DApps, but not for Bridge or Earn. A Gas Card is bought with USDT or USDC on BNB Chain, or USDT on Polygon, up to $10 per card; the purchase is itself a transaction, whose fee is paid in that network’s coin or with another Gas Card. A card shared by another user is redeemed with its code at no cost.

Pay the fee with a token

When tokens are sent on BNB Chain and Polygon without enough of the native coin, FxWallet can take the fee in USDT or USDC on BNB Chain, or USDT on Polygon instead. On first use, this upgrades the address with EIP-7702, which can be undone in the account’s settings.

Neither works with watch-only or hardware wallets, and both use Normal speed.

Coverage and limits

  • Swap runs on 14 networks: Ethereum, Solana, BNB Chain, Polygon, Arbitrum, Base, and 8 more networks. It trades within one network; Bridge moves tokens between networks.
  • Bridge connects 32 EVM networks, with routes from several bridges.
  • Some routes carry an FxWallet service fee, shown in the quote as “Fee (x%)”; on others it is 0%. The network fee and any DEX or bridge fee are shown as well.
  • Slippage is set automatically unless a custom value is entered.
  • Before a swap, GoPlus checks the token on the networks it covers: FxWallet will not buy tokens flagged as honeypots and warns about other red flags. Trades with a very high price impact are stopped.
  • Native bridges from a layer-2 network back to Ethereum take about a week and end with a claim transaction.
Does FxWallet charge a fee on swaps and bridges?

Some routes include an FxWallet service fee, shown in the quote as “Fee (x%)” before you confirm; on others it is 0%. You also pay the network fee, and a DEX or bridge may charge its own fee. All of them are shown before you sign.

Can I swap a token on one network for a token on another?

Not in Swap, which trades within one network. Bridge moves tokens between networks and shows the amount that can be received on the destination network.

How long does a bridge transfer take?

Each quote shows an estimate, which depends on the route. Native bridges from a layer-2 network back to Ethereum take about a week because of their challenge period and are completed with a claim transaction.

What is a Gas Card?

Prepaid credit that FxWallet uses to pay network fees on BNB Chain, Polygon, Arbitrum, and Optimism. A Gas Card is bought with USDT or USDC on BNB Chain, or USDT on Polygon, up to $10 per card, or redeemed from a code shared by another user. Transactions paid with a Gas Card use Normal speed and may take longer, and the amount taken from the card can be slightly higher than the network fee.

How can I get a Gas Card without any coin for network fees?

Ask someone who has a Gas Card to share one with you: redeeming it with its code costs nothing. Buying a card yourself is a transaction that needs a little of the network’s coin.
