S (S) Tokenomie

The transition from Fantom (FTM) to Sonic (S) represents a comprehensive rebranding and technical evolution of the ecosystem. The S token serves as the native utility and governance token for the new Sonic Layer-1 blockchain, maintaining a supply structure that mirrors the original Fantom Opera network while introducing new inflationary and incentive mechanisms.

Issuance Mechanism

The S token was designed with an initial total supply of 3.175 billion, matching the maximum supply of FTM. The issuance follows a multi-phased approach:

• 1:1 Migration: FTM holders can exchange their tokens for S at a 1:1 ratio. For the first 90 days following the December 2024 launch, a bridge enabled bidirectional swaps. After this period, the process transitioned to a one-way swap from FTM to S.
• Validator Rewards Migration: Remaining inflationary FTM block rewards from Fantom Opera were migrated to Sonic at launch. These rewards incentivize Sonic validators for the first four years at a rate of approximately 70.07 million S per year (roughly 2.21% of the initial supply).
• Perpetual Inflation: After the initial four-year period, S will transition to perpetual inflationary emissions to fund block rewards. The target inflation rate is 1.75% per year, assuming 50% of the total supply is staked.
• Operational Funding: Six months after launch, S began additional inflationary emissions at an annual rate of 1.50% of the initial supply (approx. 47.63 million S) for six years. These tokens are directed to Sonic Labs for network growth, with any unused tokens burned at the end of each year.

Allocation Mechanism

The allocation of the SONIC supply is heavily weighted toward community and ecosystem growth. As of early 2025, the distribution is structured as follows:

Notably, approximately 57% of the total supply is allocated to the community through the Ecosystem, HyperGrid Rewards, Early Supporters, and Initial Claim categories.

Usage and Incentive Mechanism

The S token is central to the Sonic network's functionality and its "builder-first" philosophy:

• Transaction Fees: S is used to settle all network transaction fees.
• Staking and Validation: Users must stake a minimum of 50,000 S to operate a validator node. Validators earn block rewards consisting of token emissions and transaction fees.
• Governance: Tokenholders who stake S can participate in the governance of the Sonic network.
• Fee Monetization (FeeM): A unique incentive where developers can earn up to 90% of the gas fees generated by their applications, while the remaining 10% is distributed to validators.
• Ecosystem Funds: The Sonic Labs Innovator Fund was allocated up to 200 million S to accelerate partner migration and support infrastructure providers. Other programs include Sonic Boom (developer points called "Gems") and Sonic Spark (grants for DeFi, Gaming, and SocialFi).

Locking and Unlocking Mechanism

Sonic employs specific locking and vesting schedules to manage liquidity and encourage long-term participation:

• Airdrop Vesting: A total of 190.5 million S (6% of the initial supply) was allocated for an airdrop to historic Fantom and new Sonic users. The distribution uses a "deflationary" model:
  • 25% is unlocked and liquid on the first day.
  • 75% is vested over nine months (270 days) as ERC-1155 NFT positions.
  • Early Claim Penalty: Users can claim their full allocation before the nine-month period ends, but they incur a burn penalty on the unvested portion.
• Staking Lock-up: S token staking features a maximum lock-up period of 14 days, designed to facilitate a more efficient experience for liquid staking protocols.
• General Vesting: The broader token supply is projected to reach full vesting by 2029. While the "Initial Claim" was available at launch, allocations for Investors and the Foundation follow a gradual release schedule. The Ecosystem and HyperGrid Rewards portions do not have predefined, rigid vesting schedules, allowing for flexible distribution based on network needs.
