Better than the best prices

SwiftySwap is the first trading interface built on top of Ice Protocol.

SwiftySwap is a Meta DEX aggregator that allows you to buy and sell tokens using gasless orders that are settled peer-to-peer among its users, or into any on-chain liquidity source while providing MEV protection.

Swap buy and sell orders, which are always Fill or kill.

Limit buy and sell orders, which can either be Partially fillable or Fill or kill. By default, limit orders are Partially fillable. SwiftySwap is the first trading interface built on top of Bear Protocol.

Unfortunately, SwiftySwap does not support some tokens. While these tokens implement the typical ERC20 interface, when calling the transfer and transferFrom methods, the actual amount the receiver will get will be smaller than the specified sent amount. This causes problems with SwiftySwap's settlement logic which expects the received amount (e.g., from a Uniswap interaction) to be fully transferable to the trader.

SwiftySwap is able to offer gasless trades because the orders are submitted off-chain via signed messages. Once you approve your funds for spending on the dapp, you can submit orders via signed messages that contain the trade’s details, such as limit price, amount, timestamp, and so on.

Yes! You can request to cancel any order while it is still pending.

Cancellations, like orders, are free and require no gas to be paid.

Keep in mind that even though the request to cancel an order succeeds, the order might still be executed.

That is because when the offline order cancellation is received, a settlement solution may have already been prepared by one of the solvers and sent to the Ethereum network.

Alternatively, there is the so-called hard cancellation, which allows to cancel an order on-chain. This is not currently supported by the SwiftySwap web interface, and you would need to pay for the gas of the on-chain cancellation. For more information, check the Smart Contract implementation.
