The blockchain landscape is evolving rapidly, and one of the most anticipated transitions in 2025 is the migration from Fantom (FTM) to Sonic (S). In mid-December, Sonic Labs officially launched the Sonic mainnet, a high-performance, EVM-compatible Layer-1 (L1) blockchain designed to empower developers with enhanced infrastructure, scalability, and improved incentive mechanisms.
As part of this strategic upgrade, both the Fantom network and its native FTM token are transitioning to the new Sonic blockchain and its S token. This marks a significant milestone in the evolution of decentralized ecosystems, offering users faster transactions, lower fees, and greater interoperability.
Whether you're a long-term FTM holder or an active DeFi participant, understanding how to smoothly migrate your assets is crucial. This guide walks you through every step of the Fantom to Sonic migration process, including wallet transfers, staking implications, liquidity pool handling, and more.
Understanding the FTM to S Migration
The transition from Fantom to Sonic isn’t just a rebrand—it’s a full-scale network upgrade. The new Sonic chain operates independently as a fresh EVM-compatible Layer-1, meaning it starts with a clean slate: no transaction history carries over. However, your FTM balance will be mirrored 1:1 into the new S token.
This migration ensures continuity for users while unlocking next-generation performance. The upgrade is coordinated by Sonic Labs, which has introduced an official portal—MySonic—to streamline the process for both casual holders and advanced users.

Migration for Centralized Exchange (CEX) Users
If you hold your FTM tokens on a centralized exchange like Binance, OKX, or Kraken, your role in the migration is simple: you don’t need to do anything manually.
Sonic Labs has partnered with major exchanges to enable automatic 1:1 conversion of FTM to S. Once the integration is complete, your FTM balance will seamlessly convert to S within your exchange account.
However, it’s important to:
- Confirm that your exchange supports the migration.
- Monitor official announcements from your CEX regarding timelines.
- Avoid withdrawing FTM during the transition window unless you’re ready to use the on-chain bridge.
This automated path ensures security and convenience for the majority of users who prefer not to manage private keys or interact with smart contracts.
On-Chain Migration Using MySonic Upgrade Portal
For users who self-custody their assets in non-custodial wallets (e.g., MetaMask, Trust Wallet), manual migration via the MySonic upgrade portal is required.
Here’s a step-by-step breakdown:
- Visit the Official Portal: Go to my.soniclabs.com/upgrade
(Note: Always verify the URL to avoid phishing sites.) - Connect Your Wallet: Use any Web3-compatible wallet (MetaMask, WalletConnect, etc.) to securely connect to the platform.
- Enter Migration Amount: Input the amount of FTM you wish to upgrade. The system will display the equivalent amount of S you’ll receive—always a 1:1 ratio.
- Review Details: Double-check that the receiving address matches your connected wallet and that the conversion rate is accurate.
- Pay Network Fee: A small gas fee in FTM is required to process the transaction on the Fantom network.
- Approve & Confirm: Sign the approval transaction, followed by the final migration transaction.
Within seconds—typically under a minute—your S tokens will appear in the same wallet address on the Sonic network.
✅ Pro Tip: Ensure your wallet supports the Sonic network. You may need to manually add Sonic’s RPC details for full visibility of your S balance.
What Happens After Migration?
90-Day Two-Way Swap Window
For the first 90 days after launch, users can freely swap between FTM and S in both directions. This grace period allows flexibility for corrections, delayed migrations, or testing purposes.
After this window closes, only one-way swaps (FTM → S) will be permitted, effectively phasing out the old Fantom chain over time.

Staking and Validator Considerations
At launch, users will be able to:
- Unlock previously staked FTM tokens
- Migrate them via the bridge
- Begin staking S tokens on the new Sonic network
Validators and delegators should coordinate with their node operators or staking platforms to ensure smooth transitions and uninterrupted rewards.
Handling Liquidity Provider (LP) Positions
If you’re actively providing liquidity on decentralized exchanges (DEXs) like SpookySwap or SpiritSwap, additional steps are required:
- Remove Existing LP Positions: You must first exit all LP pairs on Fantom.
- Migrate Each Token Individually: Both FTM and paired tokens (e.g., USDC, DAI) must be migrated separately.
- Recreate LP Positions on Sonic: Once assets are on Sonic, deposit them into compatible DEXs (e.g., SwapX) to re-establish liquidity pools.
This process may involve impermanent loss considerations and gas costs, so plan accordingly.
Important Limitations and Notes
- ❌ Transaction History Does Not Migrate: All past interactions remain on the original Fantom chain. Sonic launches as a new blockchain with zero historical data.
- ✅ Address Compatibility: Your wallet address remains the same across chains due to EVM compatibility.
- ⚠️ No Automatic Smart Contract Migration: dApps, NFTs, and custom contracts must be redeployed independently on Sonic by their developers.
Frequently Asked Questions (FAQ)
Q: Is the FTM to S migration mandatory?
A: Yes. Over time, the old Fantom chain will be deprecated. To continue participating in the ecosystem, migrating to Sonic is necessary.
Q: Will my FTM holdings automatically become S if I do nothing?
A: Only if they’re stored on a supported centralized exchange. For self-custodied tokens, manual migration via MySonic is required.
Q: Can I move my S tokens back to FTM after migration?
A: Yes—but only during the first 90 days. After that, reverse swaps will no longer be available.
Q: Do NFTs migrate automatically?
A: No. NFTs on Fantom will remain on the legacy chain. Projects must announce individual migration plans for their collections.
Q: Are gas fees lower on Sonic compared to Fantom?
A: Early benchmarks suggest significantly reduced fees and faster finality on Sonic due to its optimized consensus mechanism.
Q: What happens to dApps I use on Fantom?
A: Developers must port their applications to Sonic. Many are expected to do so given the improved incentives and infrastructure.
Final Thoughts
The migration from Fantom to Sonic represents more than just a token swap—it's a leap forward in blockchain performance and user experience. With seamless 1:1 conversion, strong developer support, and clear migration tools, Sonic Labs has laid a solid foundation for widespread adoption.
Whether you're a passive investor or an active DeFi user, taking action now ensures you stay ahead of the curve. Remember to verify official sources, secure your wallet, and act before the two-way swap window closes.
