Economia del token di Arbitrum (ARB)

The Arbitrum (ARB) token serves as the primary governance mechanism for the Arbitrum ecosystem, specifically governing the Arbitrum One and Arbitrum Nova networks. Launched on March 16, 2023, with a total supply of 10 billion tokens, ARB enables a decentralized community to manage protocol upgrades, treasury allocations, and the technical evolution of the network.

Issuance Mechanism

The ARB token was issued as an ERC-20 equivalent token on the Arbitrum One network. While the initial supply is capped at 10 billion tokens, the Arbitrum DAO maintains the authority to control future token inflation. The issuance was designed to distribute ownership across the community, the developing team, and early investors.

Allocation Mechanism

The initial allocation of the 10 billion ARB tokens was distributed among several key stakeholder groups to ensure a balanced governance structure. Following a reallocation of 7.5% of the total supply from the DAO to the Arbitrum Foundation, the distribution is structured as follows:

Usage and Incentive Mechanism

The ARB token is primarily a governance token. It does not function as a gas token for the network (ETH is used for transaction fees), but it provides holders with several critical rights:

• Governance Participation: Token holders can vote on Arbitrum Improvement Proposals (AIPs) via Snapshot (off-chain) and Tally (on-chain). This includes "Constitutional AIPs" that can modify the protocol's core architecture.
• Treasury Management: The DAO uses ARB to fund incentive programs. For example, the Short-Term Incentive Program (STIP) allocated 50 million ARB to ecosystem protocols, and the Gaming Catalyst Program (GCP) was approved to distribute up to 225 million ARB over three years to gaming projects.
• Security and Disputes: In the Bounded Liquidity Delay (BoLD) protocol, while ETH is currently used for challenge bonds on Arbitrum One to ensure security, the DAO has the authority to change the bonding asset to ARB in the future.
• Sequencer Profits: The protocol generates free cash flow through sequencer profits (the difference between L2 fees collected and L1 fees paid), which are directed to the DAO treasury.

Locking and Unlocking Mechanism

To prevent market oversaturation and ensure long-term alignment, a significant portion of the ARB supply is subject to a strict vesting schedule.

Locking Mechanism

While user and DAO airdrops were made available shortly after launch, all tokens allocated to investors and the Offchain Labs team were subject to a four-year lockup. These tokens remained fully locked for the first year following the token generation event.

Unlocking Schedule

The unlocking process follows a linear monthly schedule after the initial cliff. Key milestones include:

• First Major Unlock: Occurred on March 23, 2024, marking the end of the one-year cliff for team and investor tokens.
• Monthly Vesting: Following the first unlock, tokens vest monthly for the remaining three years. Approximately 1.1% of the total supply vests every month.
• Full Vesting: The entire initial supply is scheduled to be fully vested by March 2027.

As of April 2026, daily unlock events continue to distribute tokens to the DAO Treasury, Arbitrum Foundation, Team, and Investors. For instance, on April 7, 2026, approximately 513,347 ARB tokens are scheduled to be unlocked for each major recipient group, representing a consistent and systematic increase in the circulating supply.
