Mechanics of 1inch Network’s Fusion Mode

With this update, a new 1inch swap engine is introduced for filling and executing orders. Called "Fusion" on the user interface, it allows users to swap at a competitive rate without paying for gas fees and seamlessly prevents front-running (MEV) attacks. In a general sense, it can be seen as a total overhaul of 1inch Network’s existing Limit order and aggregation protocols.

Similar to a normal swap, you first enter the token amounts that you want to swap. This designates you as the "maker". Once the order is placed, resolvers (takers) compete to fill your order and also pay for any associated gas fees!

Who is a resolver?

A resolver is any address that stakes 1INCH tokens and is registered to fill 1inch Network Fusion orders.

The competition between resolvers occurs as a ‘dutch auction’, where the rate starts high, and moves lower until:

  1. The order is taken (filled) by a resolver

  2. The price moves below the user's desired slippage tolerance

  3. The order reaches its expiration time

Please note:

***If the price moves below your slippage tolerance, the swap will fail, and it must be resubmitted.

***With Fusion mode, there is no gas cost required, even for expired/failed swaps!

Why use Fusion Mode?

With this new 1inch swap engine, there are several benefits for both users and resolvers.


  • Gasless swaps (within a specific price and time range)

  • MEV protection

  • No price impact

  • No cost for failed transactions

  • Fast execution


  • Earn stake rewards

  • Resolver fees

  • Participate in the 1inch Network Gas refund program

  • Earn 1inch DAO governance voting power

How to swap:

With Fusion mode, there are several options :

Fast (recommended): Execute the fastest trade.

Fair: Execute a trade with a slower speed, but at a better rate.

Auction: Execute their trade at the best rate possible, but at the slowest speed.

Custom: This feature is under development. Stay tuned for future updates!

By default “Fast” is the recommended speed, as it offers the smoothest user experience.

How to swap:

First, connect your wallet to the 1inch dApp.

Then, enter the amounts you would like to swap, and click either “Permit and swap” or “Approve tokens” depending on the token you are selling.

Next, you will need to sign this first transaction in your wallet.

Once the approval or permit is successful, confirm the details on the following screen, and click “Confirm swap”.

What happens if my swap expires?

If the swap expires, it will need to be resubmitted. You can check the status by clicking on your connected address in the upper right corner of the screen.

How to stake

With 1inch Fusion, you can stake 1INCH tokens to earn rewards and Unicorn power. Once staked, your tokens cannot be unstaked/withdrawn without penalty until the designated lock period expires. The default lock period for staking is 2 years.

As time progresses, the penalty for unstaking 1INCH tokens decreases. Also, the longer the lock period, the more Unicorn power is received at the time of staking.

Similar to the withdrawal penalty, the amount of held Unicorn power also decreases with time.

This graph shows how both the penalty for withdrawing st1INCH and the amount of held Unicorn power decreases over time.

A guide on how to stake:

To stake tokens, first connect your wallet. Then click on the “DAO” tab, followed by “Staking”.

Next, enter the amount of 1INCH you would like to stake, set the locking period (default is 2 years) and click “Give permission to stake”. Then sign the transaction in your connected wallet.

This will permit the 1INCH tokens to be used by the smart contract and stake them in one single transaction. Once completed, your 1INCH tokens will be staked! You will then be able to see the total amount of tokens staked, your lock period, and your total Unicorn Power (used for delegation or 1inch DAO governance voting).

Please note: Unstaking before the end of the lock period will result in a penalty.

How to Delegate your Unicorn power, for either resolving or 1inch DAO governance

Stakers of 1INCH tokens can delegate their Unicorn power to both resolvers and governance participants. Delegation for Fusion resolving will deploy extra tokens for every resolver that registers as a delegate.

Any resolver who delegates for Fusion resolving will receive additional 1INCH tokens, proportionate to the amount that is delegated. This resolver-specific token will represent shares of users that delegated their “voting power” to this resolver.

Resolvers can also deploy farms from their balance of 1INCH tokens specific to reward all the delegators proportionally to their stake within each farm.

How to delegate to a resolver:

First, you will need to stake some 1INCH tokens.

Once you hold st1INCH, click on the "Earn" tab at the top of the page, and then "Delegate".

On the next screen you will see all of the available resolvers that can be delegated to. After choosing the desired resolver, click "Delegate".

Next, click "Confirm" delegation, and then confirm the transaction in your connected wallet.

Once the transaction confirms on chain, you will have successfully delegated your Unicorn Power to the resolver!

How to become a resolver:

In order to become a resolver, you must hold a balance of staked 1INCH (st1INCH) tokens.

To be put on the whitelist, resolvers will need to stake the amount of 1INCH tokens for any lock period to have enough voting power to get into "top 5" of 1inch stakers. To achieve this, a resolver can lock tokens by themselves OR attract users who delegate their voting power in exchange for rewards (farming).

Any user can lock (stake) 1inch tokens to get st1inch tokens, with a lock period between 1 month and 2 years.

Holding staked 1INCH (st1INCH) gives users “Unicorn power” which they can later use to participate in farming programs or other various activities. The longer the locking period, the more “voting power” you can get as a resolver.

In short, the amount of voting power granted is directly proportional to the amount of time that the tokens are staked.
