STRK

Overview

Similar to other blockchains, Starknet uses the STRK token for paying fees to enable operation of the network, maintaining and securing the network by enabling staking for consensus, and deciding on Starknet’s values and technology goals by voting for governance proposals, of which ten billion tokens are planned to or have already been distributed,  as well as, further tokens minted through an inflation mechanism.

The primary purpose of the Starknet token, STRK, is to facilitate operations and activities on Starknet and it is not intended to serve as an investment.

Major economic mechanisms of STRK, also known as tokenomics, are subject to change based on governance decisions made by the larger community of Starknet and are described here for informational purposes only.

For more details on Starknet’s governance processes, see the Starknet Governance Hub.

Background

Blockchains are valuable because they are data structures maintained by diverse and, ideally, large groups of otherwise unaffiliated persons. This gives them resilience: Any one participant can disappear, but the data structure is preserved. This also gives them censorship resistance: No single person can unilaterally decide to forbid certain persons from using the network.

To achieve this, blockchains work through a combination of cryptography and economic incentives: Cryptography limits what actors in the system can do (for example, transactions must be validly signed to be included in the chain) and economic incentives encourage actors to voluntarily perform actions that maintain the network’s capabilities when spending their own resources (for example, miners or stakers actively publish new blocks to the chain because they can receive fees and new tokens as a reward).

Starknet achieves secure low-cost transactions by using the STARK cryptographic proof system to reduce the size of transaction data while preserving and verifying the integrity of that data. To achieve resilience and censorship resistance, Starknet uses the STRK token to incentivize network participants to sequence transactions for users of the network and to ensure that there is a provably fair proof-of-stake mechanism to determine who should sequence and submit a proof for the network blocks.

Purposes

• Transaction fees: Originally, fees in Starknet were paid only in Ether (ETH), which was followed by the functionality of paying fees for transactions on the network using both STRK, as well as ETH. As of the release of v.0.14.0 on September 1, 2025, transaction fees on Starknet can only be paid with STRK.
  A portion of the fees paid in STRK may be converted to ETH by the receiving sequencer, in order to cover Ethereum L1 gas costs, which, due to the specifications of the Ethereum protocol, must be paid in ETH.
• Staking:  Certain services that are critical to the liveness and security of Starknet may require the staking of Starknet tokens. These services might be offered by multiple providers, and could include sequencing, reaching temporary L2 consensus before L1 finality is reached, STARK-proving services, and data availability provisioning, to name a few examples. Some of these protocol changes are still under discussion within the larger governance community and are targeted for 2025 -2026. As of the last update of this paper, staking is live and validators are required to attest blocks to ensure the network’s stability and security - for more information on Starknet staking, see here.
• Governance: Proposals for improving Starknet might require a minimal token support threshold. Voting, either directly or via delegation, will be required for changes to the protocol that are essential to Starknet’s liveness, security, and maintenance. Today, for example, major updates to the Starknet Operating System require the approval of token holders. For more information about Governance see the Starknet Governance Hub

As discussed above, the Starknet tokens are digital assets intended to support the operation and usage of Starknet and are not offered as an investment. As such, the Starknet tokens do not represent any equity in StarkWare or the Starknet Foundation, nor do they provide any participation right in StarkWare or grant any right of claim from StarkWare or the Starknet Foundation.

Supply and distribution

Ten billion Starknet tokens were initially created by StarkWare in May 2022 and minted onchain on November 30, 2022.

The existing ten billion tokens have been or are planned to be distributed according to the following:

20.04%: Early Contributors	Tokens allocated for StarkWare’s team members and early contributors. These tokens are subject to a lock-up schedule, as further detailed below.
18.17%: Investors	Tokens allocated for StarkWare’s investors. These tokens are subject to a lock-up schedule, as further detailed below.
10.76%: StarkWare	Tokens allocated for StarkWare for operation services such as to pay fees, provide other services on Starknet, and engage other service providers.
12.93%: Grants including Development Partners (aka DPs)	Tokens allocated for grants for research or work done to develop, test, deploy and maintain the Starknet protocol. The process for applications and allocations related to Starknet Foundation Grants will be outlined in a post at a later date.
9.00%: Community Provisions	Tokens distributed to those who contributed to Starknet and powered or developed its underlying technology.
9.00%: Community Rebates	Tokens allocated for rebates in Starknet tokens to partially cover the costs of onboarding to Starknet from Ethereum.
10.00%: Foundation Strategic Reserves	Tokens allocated for the Starknet Foundation to fund ecosystem activities that are aligned with the Foundation’s mission.
8.10%: Foundation Treasury	Token allocated for the Starknet Foundation’s treasury available for operations and other future initiatives by the Starknet Foundation.
2.00%: Donations	Tokens reserved for donations to institutions and organizations, such as universities, NGOs, etc, as decided by the Starknet Foundation.

To align long-term incentives of the Investors and Early Contributors with the interests of the Starknet community, and following common practice in decentralized ecosystems, all tokens allocated to Investors and Early Contributors is subject to the following lock-up schedule, where percentages are based on the total token supply:

• Up to 0.64% (64 million tokens) have been unlocked on the 15th of each month, starting April 15, 2024, and going through March 15, 2025, for a total of 7.68% (768 million tokens) unlocked by March 15, 2025.
• Up to 1.27% (127 million tokens) have been and will be unlocked on the 15th of each month, starting April 15, 2025, and going through March 15, 2027, for a total of 30.48% (3.048 billion tokens) unlocked by March 15, 2027.

The above graph excludes newly circulating tokens resulting from inflation or staking (see below).Token allotments currently retained by the Starknet Foundation, while contractually unlocked, are not considered circulating unless granted, donated, or otherwise allocated out of originating wallets through future grants, provisions, donations, developer initiatives, or other programs.

Through this lock-up period, token holders cannot transfer, sell, or pledge their STRK tokens. Delegation of voting is permitted with locked tokens. As of the last date of update of this paper, staking with locked tokens is not permitted.

The total supply of tokens increases over time with the minting of new tokens by the protocol, as staking rewards, block rewards, or other rewards associated with the staking process. Such minting is made pursuant to a schedule determined with the community (for further reading: here and here). The supply in circulation, therefore, does not remain fixed. However, as long as StarkWare is the sole operator of the Starknet sequencer, there will be no issuance of new tokens for the purpose of block rewards. For more information, see A token-minting proposal to manage inflation.

Risks and disclaimers

Starknet is a developing decentralized protocol and the economic mechanisms described herein are subject to change based on decisions made by the larger community of Starknet builders and users. Starknet relies upon third parties to adopt and implement software and protocols as users and contributors of Starknet. It also relies, in whole or partly, on third parties to develop, supply and otherwise support it. There is no assurance or guarantee that such third parties will continue to participate in the network or that the network will continue to function as intended.

The technical documents provided herein describe certain planned and specified economic fundamentals of a digital asset, STRK. These materials are intended for informational purposes only and are meant to outline the usage and functionalities of the asset within Starknet. It is important to understand that the primary purpose of STRK is to pay for fees, provide a mechanism for securing consensus, and allow for decentralized governance on Starknet; it is not intended to serve as an investment.

Starknet relies upon third parties to adopt and implement the software and protocols as users of Starknet. It also relies, in whole or partly, on third parties to develop, supply and otherwise support it. As a Layer 2 network over Ethereum, Starknet also relies upon third parties maintaining and operating the Ethereum network. There is no assurance or guarantee that those third parties will complete their work, properly carry out their obligations, and/or otherwise meet anyone’s needs.

STRK, as the native token of Starknet, may be subject to the risks of the Starknet network, including, without limitation, the following: (i) the technology associated with Starknet may not function as intended; (ii) the details of the Starknet token economics including the total supply and distribution schedule may be changed due to decisions made, amongst other, by the consensus of participants of the Starknet network; (iii) Starknet may fail to attract sufficient interest from key stakeholders or users; (iv) Starknet may not progress satisfactorily and Starknet tokens may not be useful or valuable; (v) Starknet may suffer from attacks by hackers or other individuals; and (vi) Starknet is comprised of open-source technologies that depend on a network of computers to run certain software programs to process transactions, and because of this model StarkWare and the Starknet Foundation have very limited control over Starknet.

Risks related to blockchain technology in general and Starknet in particular may impact the usefulness of Starknet, and, in turn, the utility or value of STRK. The software and hardware, technology and technical concepts and theories applicable to Starknet and STRK are still in an early development stage and there is no warranty that Starknet will achieve any specific level of functionality or success, nor that the underlying technology will be uninterrupted or error-free, and there is an inherent risk that the technology could contain weaknesses, vulnerabilities or bugs causing, potentially, the complete loss of any Starknet tokens held by Starknet users.

As with most commonly used public blockchains, STRKs held in user accounts are most commonly accessed using a private key that corresponds to the address at which they are stored. However, alternative access mechanisms, such as biometrics, multisignature setups, or other authentication methods, are also available depending on the account’s contract code. If the private key, or the “seed” used to create the address and corresponding private key are lost or stolen, the tokens associated with that address might be unrecoverable and might be permanently lost.

Public blockchain-based systems, including Starknet and the underlying Ethereum network, depend on independent verifiers, and therefore may be vulnerable to consensus attacks including, but not limited to, double-spend attacks, majority voting power attacks, race condition attacks, and censorship attacks. These attacks, if successful, could result in the permanent loss of STRK.

Starknet, STRK, and blockchain technology are nascent, and there may be additional risks not described above or that may be new or unanticipated. We recommend only using Starknet or holding STRK if you are familiar with the technology and aware of the risks.
