The blockchain landscape is evolving rapidly, and one of the most significant transitions in early 2025 is the migration from Fantom (FTM) to Sonic (S). As part of a major network upgrade, the Fantom ecosystem is rebranding and launching a new high-performance Layer-1 blockchain under the Sonic Labs banner. This shift brings enhanced scalability, faster finality, and improved developer incentives — but it also means token holders must act swiftly to ensure their assets are not left behind.
Whether you're holding FTM in a decentralized wallet or on a centralized exchange (CEX), understanding the migration process is crucial. This guide breaks down everything you need to know about the FTM-to-S swap, including which exchanges support automatic conversion, how to manually migrate your tokens, and what changes to expect with the new Sonic network.
Understanding the Fantom to Sonic Transition
Earlier in 2025, Sonic Labs — formerly known as Fantom — announced the official launch of the Sonic mainnet, an EVM-compatible Layer-1 blockchain designed for speed and efficiency. With capabilities like 10,000+ TPS and sub-second finality, Sonic aims to become a premier infrastructure platform for developers building scalable dApps.
As part of this transformation, all existing Fantom (FTM) tokens will be upgraded to Sonic (S) tokens. The total supply remains consistent at 3.175 billion tokens, ensuring no dilution or inflation during the transition. The circulating supply of S will mirror that of FTM at the time of migration.

This rebranding isn't just cosmetic — it reflects a deeper technological evolution. However, for token holders, the core value remains intact. Your FTM holdings will seamlessly convert to S, preserving market cap and ownership stakes.
Which Centralized Exchanges Support the FTM to S Swap?
One of the biggest advantages for users holding FTM on centralized platforms is that many major exchanges are offering automatic token swaps. If your FTM is stored on a supporting CEX, you don’t need to take any action — the exchange will handle the entire migration process behind the scenes.
Below is a comprehensive list of exchanges confirmed to support the FTM-to-S transition:
Exchanges Supporting Automatic Migration
- Binance – Full swap support with automatic conversion
- Bybit – Supports spot and futures delisting with seamless token upgrade
- OKX – Confirmed support for deposit, trading, and staking of S tokens
- KuCoin – Enabled migration across spot, margin, and futures markets
- Bitget, Gate.io, HTX, CoinEx, Crypto.com, MEXC, Phemex, Pionex, Tapbit, XT.com, Bitrue, Bitunix, LBank, WhiteBit, and BingX – All have announced full support
Notably, some exchanges initially planned to delist FTM but reversed their decisions. BloFin and Bitfinex, for example, now support the swap after community feedback. On Bitfinex, users can deposit FTM until February 13, 2025, though most other platforms halted deposits by January 13.
Exchanges Not Supporting the Swap
- Kraken – No official support announced
- PrimeXBT – Announced full delisting without migration options
If your FTM is on an unsupported exchange, immediate action is required. You should withdraw your tokens before withdrawal functions are disabled.

What Changes With the Sonic (S) Token?
The S token is the native cryptocurrency of the Sonic blockchain. It serves multiple critical functions:
- Paying transaction fees
- Staking and validator operations
- Governance participation
- Incentivizing ecosystem growth
For the first six months post-launch, no new tokens will be minted beyond the initial 3.175 billion supply. Afterward, additional S tokens will be gradually released to fund partnerships, ecosystem development, and network scaling initiatives.
A key feature during the transition period is the two-way swap window: for the first 90 days after launch, users can freely convert between FTM and S. After this grace period, only one-way swaps (FTM → S) will be allowed.
How Does the Swap Work on Supported Exchanges?
On CEXs that support the migration:
- Your FTM balance will automatically convert to S
- No user confirmation or manual steps are needed
- Trading pairs will update from FTM/USDT to S/USDT
- Deposits and withdrawals of FTM will be disabled
However, there are important implications for active traders:
Spot Market Orders
All open buy/sell orders involving FTM will be canceled. You’ll need to re-enter your trades once S becomes available.
Futures Positions
This is critical: all open FTM futures positions will be forcibly liquidated. Exchanges will close both long and short positions regardless of profit or loss. The new S token will have its own separate futures contracts — your previous exposure does not carry over.
How to Manually Migrate FTM to S
If you prefer full control or your exchange doesn’t support the swap, you can migrate manually using the official upgrade portal.
Step-by-Step Manual Migration
- Go to my.soniclabs.com/upgrade
- Connect your Web3 wallet (e.g., MetaMask)
- Enter the amount of FTM you wish to upgrade
- Review the equivalent S token amount
- Pay the nominal gas fee and confirm the transaction
- Receive S tokens on the Sonic network within seconds
You retain full control throughout this process. Just ensure your wallet supports custom RPC configurations for the new Sonic chain.
Frequently Asked Questions (FAQ)
Will my FTM automatically become S on all exchanges?
No — only exchanges that officially support the migration will perform automatic swaps. Check the list above to confirm if your platform is included.
Can I still use my FTM after January 13, 2025?
On most supported exchanges, FTM deposits were disabled after January 13. Withdrawals may remain open slightly longer, but delaying increases risk of inaccessibility.
Do I lose money during the FTM to S conversion?
No. The migration is a 1:1 swap with no change in value or supply. Your holdings are preserved exactly as they were.
What happens if I don’t migrate my FTM?
Unmigrated tokens may become illiquid or untradable over time. While FTM might retain some legacy value, future development and incentives will focus entirely on S.
Can I stake S tokens right after migration?
Yes — staking will be supported from day one on both decentralized platforms and participating exchanges.
Is Sonic secure and audited?
Sonic Labs has conducted third-party audits and implemented formal verification methods to enhance network security and reliability.

Final Thoughts: Act Now to Secure Your Assets
The transition from Fantom to Sonic represents more than a name change — it’s a strategic leap toward a faster, more scalable blockchain future. For investors and users, the key takeaway is simple: ensure your FTM is either on a supporting exchange or migrated via the official bridge.
With most CEXs completing swaps automatically, passive holders have little to worry about — as long as they’re on the right platform. Active traders must close futures positions and adjust spot orders accordingly.
As always in crypto, self-custody and timely action are your best defenses against disruption. Whether you choose convenience or control, now is the time to act.
