توكنوميكس SEI (SEI)

Overview

Sei (SEI) is the native token of the Sei Network, a high-performance Layer-1 blockchain optimized for digital asset exchange. The SEI token is central to the network’s security, governance, and ecosystem growth, with a total capped supply of 10 billion tokens. Its tokenomics are designed to incentivize long-term participation, decentralization, and sustainable ecosystem development.

1. Issuance Mechanism

• Total Supply: 10 billion SEI (fixed cap).
• Initial Distribution: At mainnet launch, a portion of tokens was unlocked, with the remainder subject to multi-year vesting schedules.
• Inflation: A portion of tokens (up to 15% of total supply) is distributed as inflationary rewards to validators over 10 years, supporting network security and participation.

2. Allocation Mechanism

3. Usage and Incentive Mechanism

• Network Fees: SEI is used to pay transaction fees on the Sei blockchain.
• Staking & Security: SEI holders can delegate tokens to validators or run their own validator node, securing the network and earning staking rewards. Staking rewards are distributed pro-rata, minus validator commission.
• Governance: Staked SEI grants voting power for on-chain governance proposals, allowing holders to influence protocol upgrades and parameters.
• Ecosystem Incentives: The Ecosystem Reserve funds grants, airdrops, and incentives for builders, contributors, and users.
• Collateral & DeFi: SEI can be used as native collateral in DeFi applications and for liquidity provision.
• Fee Markets: Users can pay tips to validators for transaction prioritization, with rewards shared with delegators.
• Trading Fees: SEI is used as a fee token for exchanges built on Sei.

4. Locking and Unlocking Mechanism

• Vesting Schedules: Most allocations (except Binance Launchpool) are subject to multi-year vesting with cliffs and linear unlocks.
• Staking Lock: Staked SEI is subject to a 21-day unbonding period before it can be withdrawn.
• Slashing: Misbehaving validators can be penalized (slashed), burning a portion of staked SEI.

5. Unlocking Timeline

• Start: August 2023 (mainnet launch)
• End: August 2032 (final vesting/unlock for all major allocations)
• Monthly Unlocks: Most allocations unlock monthly after their respective cliffs.
• Cliff Periods: Team and Private Sale allocations have a 1-year cliff before vesting begins.

7. Additional Notes

• No ICO or Community Sale: SEI was not distributed via a public ICO; distribution was through airdrops, launchpool, and private sales.
• Staking APR: As of early 2024, staking APR was ~4.46%, subject to change based on network conditions.
• Governance: Proposals require a minimum deposit (3,500 SEI, or 7,000 SEI for expedited proposals) and a 2-day deposit period (1 day for expedited).
• No Minimums/Maximums: No minimum or maximum for amount staked or number of delegators.

9. Implications and Analysis

• Long-Term Alignment: The extended vesting schedules for team and investors align incentives with the network’s long-term success.
• Ecosystem Growth: Nearly half the supply is reserved for ecosystem development, supporting grants, incentives, and user growth.
• Decentralization: Staking and governance mechanisms empower the community, while slashing and unbonding periods ensure network security.
• Unlocking Risks: Gradual unlocks help mitigate inflation and price volatility, but large unlock events (especially after cliffs) may impact market dynamics.

In summary:
Sei’s token economics are structured to balance immediate ecosystem needs with long-term sustainability, using a combination of cliffs, linear vesting, and broad-based incentives to foster a robust, decentralized, and innovative blockchain ecosystem.
