S (S) טוקנומיקה

The transition from Fantom (FTM) to Sonic (S) represents a comprehensive rebrand and technical upgrade, introducing a new native token, S, to power the high-throughput Sonic Layer-1 blockchain. The tokenomics are designed to mirror the existing FTM supply while introducing new inflationary and incentive mechanisms to support long-term network growth.

Issuance Mechanism

The S token serves as the native utility token for the Sonic network. Its issuance is primarily governed by a 1:1 migration from FTM and subsequent inflationary rewards.

• Initial Supply: The initial total supply of S is set at 3.175 billion, matching the maximum supply of FTM.
• 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 enables bidirectional swaps. After this period, the process transitions to a one-way swap from FTM to S.
• Inflationary Emissions:
  • Validator Rewards: Remaining inflationary FTM block rewards from Fantom Opera will migrate to Sonic. These will incentivize validators for four years at a rate of approximately 70.07 million S (~2.21% of initial supply) per year.
  • Perpetual Inflation: After the initial four-year period, S will transition to a perpetual inflationary model with a target rate of 1.75% per year (assuming 50% of the supply is staked).
  • Operational Funding: Six months after launch, an additional 1.50% annual inflation (~47.63 million S) will be introduced for six years to fund Sonic Labs' operations, including dApp growth and partnerships. Unused tokens from this allocation are burned at the end of each year.

Allocation Mechanism

The allocation of S tokens is divided between the migrated FTM supply, new ecosystem incentives, and historical distributions.

Note: The historical FTM allocations for the team and advisors were reported as fully vested as of December 2024.

Usage and Incentive Mechanism

The S token is central to the Sonic ecosystem, serving multiple functional and economic roles:

• 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 and transaction fees.
• Delegation: Tokenholders can delegate their S to existing validators to share in rewards, minus a commission fee.
• Governance: Stakers are eligible to participate in network governance, though specific mechanisms are still being finalized.
• Ecosystem Incentives:
  • Sonic Boom: A program offering "Sonic Gems" (points) to developers building innovative applications.
  • Gas Fee Monetization: Designed to incentivize developers by allowing them to earn a portion of the gas fees generated by their dApps.
  • Sonic Gateway: A decentralized bridge between Ethereum and Sonic that includes a fail-safe mechanism allowing users to unlock assets on Ethereum if the bridge fails for more than 14 days.

Locking and Unlocking Mechanism

Sonic employs a unique "deflationary airdrop" and vesting strategy to manage supply pressure.

Airdrop Vesting and Burn Penalty

The 190.5 million S token airdrop for developers and early users utilizes a linear decay mechanism to encourage long-term holding:

• Initial Unlock: 25% of the airdrop allocation is available on the first day.
• Vesting Period: The remaining 75% vests over nine months (270 days) as ERC-1155 NFT positions.
• Early Claim Penalty: Users can claim their vested tokens before the nine-month period ends, but they will incur a burn penalty. The closer to the start date a user claims, the higher the percentage of tokens burned.
• Secondary Market: These NFT positions can be traded on a marketplace, allowing users to sell their future claims to speculative buyers without triggering an immediate token burn.

Validator Locking

While specific lock-up durations for general staking were not detailed, the network relies on the 50,000 S minimum stake for validators to ensure network security and commitment.
