Sonic Labs Says Its Layer-1 Blockchain Will Go Public ‘Soon’

·

The blockchain landscape continues to evolve at a rapid pace, and one of the most anticipated developments in late 2025 is the imminent public launch of Sonic, a high-performance Layer-1 blockchain developed by Sonic Labs. After achieving Genesis — the foundational first block that marks the birth of a new blockchain — the team has confirmed that the network is now entering its final deployment phase before going live to the public.

“Genesis achieved. Block zero. Infrastructure deploying. Public soon,” announced Sonic Labs in a recent post on X, signaling that the long-awaited mainnet launch is just around the corner.

A New Chapter for the Fantom Ecosystem

Sonic is not merely an upgrade — it’s a fully independent Layer-1 blockchain designed to succeed the Fantom Opera network. While it maintains strong ties with its predecessor, Sonic operates as a separate chain with enhanced capabilities focused on speed, scalability, and developer incentives.

One of the most significant transitions for existing users involves the token swap from FTM to “S” tokens. At launch, FTM holders will be able to exchange their tokens for the new S tokens on a 1:1 basis, ensuring a smooth migration path for the community.

This rebranding from Fantom Opera to Sonic reflects more than just a name change; it represents a strategic shift toward reducing latency, lowering transaction fees, and delivering a next-generation infrastructure for decentralized applications (dApps).

High-Speed Performance Meets EVM Compatibility

At its core, Sonic is an Ethereum Virtual Machine (EVM)-compatible blockchain, making it accessible to millions of developers already familiar with Ethereum-based tools and smart contracts. But what sets Sonic apart is its relentless focus on performance.

During its testnet phase, Sonic achieved a transaction finality of just 720 milliseconds — the time it takes for a transaction to become irreversible. This level of speed positions Sonic as a serious competitor to leading high-throughput chains like Solana and Base, especially within the EVM ecosystem.

With such low finality times, Sonic aims to deliver near-instant transaction confirmations, creating a seamless user experience for both consumers and developers building on the network.

Developer-Centric Incentives

Sonic Labs has placed developers at the heart of its design philosophy. According to Andre Cronje, Chief Technology Officer of Sonic Labs and former Chair and Technical Advisor of Fantom (2018–2022), 90% of all transaction fees generated on the network will be returned directly to developers.

This unprecedented incentive model is designed to attract top-tier talent and foster rapid innovation within the ecosystem. By rewarding developers so generously, Sonic hopes to become the go-to platform for building scalable dApps, DeFi protocols, and NFT marketplaces.

Testnet 2.0: The “Blaze” Upgrade

Just days before announcing Genesis, Sonic unveiled Testnet 2.0, codenamed “Blaze”, on December 1. This upgraded test environment allowed developers and early adopters to stress-test the network under real-world conditions, fine-tuning performance and security ahead of mainnet launch.

The successful rollout of Blaze demonstrated Sonic’s resilience and readiness for large-scale adoption. It also provided critical data that helped optimize consensus mechanisms, node synchronization, and overall network throughput.

S Token Airdrop Snapshot Complete

In preparation for the mainnet launch, Sonic completed a snapshot for its S token airdrop on December 2. Approximately 200 million S tokens will be distributed to eligible participants who engaged with Sonic’s ecosystem prior to the snapshot date.

Users could earn S tokens by participating in Sonic’s arcade games, including Coinflip, Rock, Paper and Scissors, Plinko, and Mines — gamified experiences designed to boost engagement and onboard new users into Web3.

However, these games have now been officially retired as Sonic shifts focus from community growth to full-scale deployment.

Once the mainnet goes live, users will be able to claim their S tokens and participate in staking, governance, and ecosystem development.

Proof-of-Stake Consensus and Staking Opportunities

Sonic operates on a proof-of-stake (PoS) consensus mechanism, aligning with modern blockchain standards for energy efficiency and decentralization. S token holders will have the ability to stake their tokens to secure the network and earn passive rewards.

Staking not only incentivizes long-term holding but also strengthens network security by increasing the cost of potential attacks. As more users stake their tokens, Sonic becomes more resilient and decentralized.

The Role of the Sonic Foundation

Launched in May, the Sonic Foundation plays a pivotal role in guiding the future of the blockchain. Tasked with overseeing governance, managing the treasury, forming strategic partnerships, and nurturing the DeFi ecosystem, the foundation ensures that Sonic remains community-driven and sustainably developed.

Backed by the Fantom Foundation — a nonprofit that has supported Fantom’s DeFi growth since 2019 — Sonic benefits from years of accumulated expertise and established infrastructure.

This institutional support provides credibility and stability as Sonic transitions from development to mainstream adoption.
