In January 2025, the Fantom blockchain completed the most radical self-reinvention in crypto: it rebranded entirely to Sonic, migrated all FTM holders to a new S token at 1:1 ratio, launched an upgraded blockchain architecture targeting 10,000 transactions per second, and grew its DeFi TVL from $27 million to over $1 billion in just eight weeks. For presale investors looking at fast-growing ecosystems in 2026, Sonic is one of the most important case studies available.
From Fantom to Sonic: What Changed
Fantom launched in 2018 as a DAG-based blockchain using the Lachesis consensus mechanism. By 2023 it had a strong DeFi ecosystem but struggled with declining TVL and developer attention as newer chains (Arbitrum, Base, Optimism) captured EVM activity. The decision to rebrand wasn't just cosmetic — it involved a complete infrastructure overhaul:
- New blockchain architecture with fully upgraded execution engine
- New native token: S (replacing FTM at 1:1 ratio)
- New incentive model: FeeM (Fee Monetisation for developers)
- New Ethereum bridge: Sonic Gateway
- New branding, website, and developer tooling from scratch
The migration window for FTM → S conversion was announced in December 2024, with all existing FTM holders able to swap their tokens 1:1 for S. This guaranteed that the existing holder base — hundreds of thousands of wallets — automatically became S holders at launch without losing any value.
Technology: 10,000 TPS and 720ms Finality
Sonic's performance benchmarks represent a genuine step forward from original Fantom:
- 10,000+ TPS on the upgraded execution layer
- 720 millisecond finality — transactions confirmed in under one second
- Lachesis ABFT consensus — the same asynchronous Byzantine Fault Tolerant mechanism that made Fantom fast, now upgraded for greater throughput
- Full EVM compatibility — all Ethereum Solidity contracts deployable without modification
At 720ms finality, Sonic is faster than most payment processors. This makes it viable for real-time applications — gaming, micro-transactions, high-frequency DeFi strategies — that are impractical on Ethereum (12 second blocks) or even Polygon (2 second blocks).
FeeM: Developers Earn 90% of Gas Fees
Sonic's most innovative feature is Fee Monetisation (FeeM). In standard blockchains, gas fees go to validators. In Sonic, developers who deploy smart contracts earn up to 90% of the gas fees generated by users interacting with their contracts. Validators receive the remaining 10%.
This fundamentally changes the developer incentive model. Instead of paying to deploy a contract and hoping users pay subscription fees, Sonic developers earn directly from usage. A DEX generating $1M in daily gas fees returns $900,000 per day to its development team under FeeM. This makes Sonic uniquely attractive for developer acquisition — which drives protocol launches — which drives TVL — which attracts presale projects.
TVL Growth: $27M to $1B in 8 Weeks
Sonic's TVL trajectory was extraordinary. At mainnet launch in January 2025, TVL sat at approximately $27 million. By early March 2025 — just eight weeks later — TVL had crossed $1 billion, a 2,951% increase in under two months.
This growth was driven by three factors: the 1:1 FTM migration bringing in existing liquidity, aggressive FeeM rewards attracting DeFi developers from other chains, and Sonic Gateway enabling seamless capital inflow from Ethereum without high bridge fees.

Top Sonic dApps and Presale Projects
By mid-2025, Sonic had established a distinct DeFi ecosystem with several high-profile protocols:
- Silo Finance: Isolated lending markets that prevent systemic risk — TVL quickly exceeded $200M on Sonic
- Shadow Exchange: Sonic's native DEX with innovative tokenomics linking trading volume to protocol revenue
- Rings Protocol: Sonic's native stablecoin protocol, with $108M in stablecoin TVL within months of launch
- SpookySwap (migrated): The original Fantom AMM, which migrated to Sonic and remains the largest legacy DEX by volume
Several of these protocols launched presales or IDOs for their governance tokens before full release. The pattern is consistent: protocols building on Sonic use the chain's fast finality and FeeM to justify launching their own token sales to capture early supporters.
Sonic Gateway: Ethereum Bridge
Sonic Gateway allows assets to move between Ethereum and Sonic with minimal fees and fast confirmation times. This is critical for DeFi TVL — without an efficient Ethereum bridge, Sonic would struggle to attract the large capital pools that currently sit in Ethereum DeFi. Sonic Gateway uses a secure multi-sig architecture with planned migration to a trust-minimised ZK-proof bridge in 2026.
How to Find Sonic Presales in 2026
Sonic ecosystem presales typically appear in three places: the official Sonic Foundation ecosystem page (sonic.org), dedicated Sonic community Discord servers, and crypto presale aggregator sites. Key evaluation criteria for Sonic-specific projects:
- Does the project use FeeM effectively — does its token model depend on genuine on-chain fee revenue?
- Has the smart contract been audited by a reputable firm? See our smart contract audit verification guide to confirm any Sonic dApp audit is real, and our presale phishing guide for spotting fake Sonic presale sites on Telegram.
- Is liquidity locked post-launch, or can the team remove it?
- What is the token's fully diluted valuation at presale price versus comparable Sonic ecosystem projects?
Glossary
- FeeM (Fee Monetisation)
- Sonic's system where developers earn up to 90% of gas fees generated by users interacting with their smart contracts, creating a direct revenue model for protocol builders.
- Lachesis ABFT
- Sonic's asynchronous Byzantine Fault Tolerant consensus mechanism, enabling sub-second finality without requiring synchronous communication between all validators.
- Sonic Gateway
- Sonic's official Ethereum-to-Sonic bridge, allowing assets to move between chains with low fees and fast confirmation times.
- TVL (Total Value Locked)
- The total value of assets deposited in a blockchain's DeFi protocols. Sonic grew TVL from $27M to $1B+ in eight weeks after January 2025 launch.
- S Token
- Sonic's native currency, replacing Fantom's FTM at a 1:1 conversion ratio in January 2025. Used for gas fees, staking, and governance.
- Isolated Lending Market
- A lending system (like Silo Finance) where each asset pair operates in its own pool, preventing bad debt in one market from affecting others.
