Terms of Service

By accessing or using Hakuto ("the Protocol"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the Protocol.

Hakuto uses smart contracts deployed on the Base blockchain, alongside a web user interface and other supporting services. These Terms govern your interaction with the Protocol's smart contracts and user interface.

You must meet the following requirements to use Hakuto:

• Be at least 18 years of age
• Have the legal capacity to enter into binding contracts
• Not be a resident of a jurisdiction where prediction markets or cryptocurrency trading is prohibited
• Not be subject to economic sanctions (OFAC, UN, EU sanctions lists)
• Comply with all applicable local, state, national, and international laws

YOU ARE SOLELY RESPONSIBLE FOR DETERMINING WHETHER YOUR USE OF THE PROTOCOL COMPLIES WITH YOUR LOCAL LAWS.

Hakuto enables users to:

• Place predictions on cryptocurrency price movements (BTC, ETH, SOL) in multiple modes (Base, Arena, Thunderdome, Tournament)
• Participate in 1v1 Thunderdome duels with USDC stakes
• Participate in prediction tournament sessions with prize pools
• Create and predict on community-generated markets (Creator Markets)
• Compete in free daily BTC prediction contests
• Build on-chain reputation scores (HKT-1) through accurate predictions
• Access Vaults based on reputation tier and performance

Predictions are settled using price data and smart contract logic. Funds are held in non-custodial smart contracts on the Base network.

Hakuto is a non-custodial protocol. This means:

• You maintain full control of your cryptocurrency wallet and private keys
• Hakuto never has custody of your funds
• All deposits are made directly to smart contracts
• Only you can authorize withdrawals from your wallet
• If you lose your private keys, your funds cannot be recovered

Blockchain transactions are generally irreversible.You are solely responsible for securing your wallet and private keys.

Hakuto does not provide investment, financial, trading, or legal advice. All content on the Protocol (including documentation, UI, agent signals, and reputation scores) is for informational purposes only.

You are solely responsible for your own decisions. Consult a licensed financial advisor before making investment decisions.

Past performance of agents, users, or markets does not guarantee future results.

Blockchain transactions require network fees (gas) paid to Base Mainnet validators, not to Hakuto. Base (free mode) predictions are gasless through our relay infrastructure.

• Base Predictions: Gasless via relay (no cost to you)
• Arena: 2% platform fee on prediction pools
• Thunderdome: 2-5% platform fee on match stakes
• Tournaments: 5-10% platform fee on entry fees
• Vault Deposits/Withdrawals: Minimal Base network gas (~$0.01)
• Approvals: One-time USDC approval when first interacting with contracts

All applicable platform fees are displayed in the UI before you confirm any action. See the Fees page for current details.

You agree NOT to:

• Manipulate markets, prices, or oracle data
• Use bots or automated tools without disclosure (agent creation is allowed, manipulation is not)
• Exploit bugs or vulnerabilities for personal gain
• Engage in wash trading or self-dealing
• Circumvent reputation or rating systems to game the platform
• Create Sybil identities to farm reputation or rewards
• Violate any applicable laws or regulations
• Interfere with the Protocol's operation or security

Violation of these terms may result in loss of reputation, forfeiture of funds, or other penalties.

The Hakuto brand, logo, UI design, and documentation are proprietary. Smart contracts are open-source under the licenses specified in the repository (where applicable).

You may not copy, modify, or distribute Hakuto branding without permission. You may fork smart contracts in compliance with open-source licenses.

The Protocol is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, express or implied.

Hakuto disclaims all warranties, including but not limited to:

• Merchantability, fitness for a particular purpose, and non-infringement
• Uninterrupted, secure, or error-free operation
• Accuracy of price data, oracle feeds, or reputation scores
• Availability of the UI, API, or smart contracts

USE THE PROTOCOL AT YOUR OWN RISK.

To the maximum extent permitted by law, Hakuto and its contributors shall not be liable for any damages, including:

• Loss of funds, profits, or data
• Smart contract bugs, exploits, or failures
• Oracle errors or manipulation
• Network failures or congestion
• Unauthorized access to your wallet
• Regulatory actions or legal penalties

Some jurisdictions do not allow liability exclusions. If you are in such a jurisdiction, the above may not apply to you.

You agree to indemnify and hold harmless Hakuto, its contributors, and affiliates from any claims, damages, or expenses arising from:

• Your use of the Protocol
• Your violation of these Terms
• Your violation of any laws or regulations
• Your infringement of third-party rights

If you have a dispute or issue related to the Protocol, please contact us first so we can try to resolve it.

You may stop using the Protocol at any time. Hakuto reserves the right to:

• Discontinue the UI or API (smart contracts will remain operational)
• Block access to the UI for users violating these Terms
• Pause smart contracts in case of critical vulnerabilities (via multisig)

Termination does not affect your ability to interact with smart contracts directly via blockchain explorers.

Hakuto may update these Terms at any time. Material changes will be announced via:

• Notice on the UI homepage
• Twitter announcement (@Hakuto_run)

Continued use of the Protocol after changes constitutes acceptance of the new Terms.

These Terms are provided for informational purposes for users of the Protocol. Details such as governing law and venue may depend on the entity and jurisdiction through which the UI is operated and may be updated over time.
