# Sonic Upgrade Stages

Migrating the hubchain to **Sonic** is a major system upgrade affecting the protocol’s architecture, mechanics, and economy. The principles of working with liquidity are changing, system resilience is increasing, and new earning opportunities are opening up for **CrossCurve** users. Below are the key stages of this transition:

### 1. Deployment of Pools on Sonic✅

Pools based on a new architecture—isolated pair pools—are being launched on **Sonic**. Previously, large multichain pools were used, combining up to 8 blockchains with synthetic derivatives. Now, each pool includes only the liquidity of one isolated blockchain and the hubchain – in this case, the liquid tokens of the **Sonic** blockchain.

This approach enhances the system’s overall resilience and reduces imbalance risks. Individually, the pools will be less liquid, but the overall architecture will provide greater flexibility, resilience, and potentially higher returns for liquidity providers. 

### 2. Whitelisting on Curve and Activation of CRV Incentives✅

We are initiating a voting process in the **Curve DAO** to get whitelisted and connect the pools to protocol reward distribution. This will allow us to activate **CRV** incentives for our pools and increase yields for our liquidity providers. Since the voting takes about two weeks, we are starting the process in advance to launch reward distribution as quickly as possible after migrating our hubchain. 

### 3. Connecting Sonic Pools to Routing

After deployment and basic setup, the **Sonic** pools will be connected to our routing system. At this stage, swaps through the new pools in **Sonic** will become available to **CrossCurve** users. To ensure a seamless transition, **Sonic** and **Fantom** pools will operate in parallel, allowing liquidity to flow between them without interrupting system functionality.

### 4. Activation of CrossCurve DAO Incentives on New Pools✅

After launching the pools and connecting them to the infrastructure, we will activate incentives from **CrossCurve DAO** – our first step in attracting liquidity to the new **Sonic** pools. External projects will be able to offer rewards to **CrossCurve DAO** participants in exchange for votes on specific liquidity pools, allowing users to start earning right away.

### 5 Connecting Sonic Gems  to Incentives on Fantom Pools✅

As Sapphire-tier winners in the **Sonic Boom** program, we possess special airdrop points called **Gems**. These are distributed among applications based on product metrics and activity. We will direct all of them toward incentivizing liquidity in our pools in the form of the **cmGEMS1** token, using it as a reward distribution mechanism within the protocol.

### 6. Disabling Incentives on Fantom Pools

As incentives are activated on **Sonic** pools, they will simultaneously be disabled on **Fantom**. However, **CRV** rewards will continue to be distributed for some time after deactivation due to the mechanics of **Curve**.

### 7. Disconnecting Fantom Pools from Routing

After most of the liquidity has been migrated to **Sonic**, **Fantom** pools will be disconnected from the routing system. Swaps through them will no longer be possible; the pools will remain accessible for withdrawals only. It is especially important for **CrossCurve** users to move their assets before this stage to avoid high slippage, as the majority of liquidity will have already been relocated.

### 8. Connecting Sonic Points and Rings to New Pools

At this stage, the pools will start generating **Sonic Points** and **Rings**, allowing liquidity providers to participate in additional reward programs, including all future airdrops. Thanks to the new pool architecture, half of the liquidity will be concentrated in Sonic blockchain assets, enabling our users to earn even more incentives

### 9. Activation of $EYWA and $CRV Rewards via Votemarket

After completing the **Curve** vote and configuring campaigns on **Votemarket**, we will activate the reward distribution in **$EYWA** and **$CRV** tokens – thus completing the migration of our hubchain to Sonic and fully launching most of the economic incentives in the new pools.
