VERSIONv1.0
01OVERVIEW

Introduction

These Terms of Service (the “Terms”) govern your access to and use of the HighGardenprotocol, websites, smart contracts, APIs, and any related services (collectively, the “Services”). HighGarden is a Solana-native prediction market that allows eligible users to trade YES/NO outcomes on real-world events, settled in USDC on Solana.

By connecting a wallet, signing a transaction, or otherwise interacting with the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

02WHO CAN TRADE

Eligibility

You may use the Services only if you are at least 18 years old (or the age of majority in your jurisdiction, whichever is greater), have full legal capacity to enter into binding agreements, and are not a person barred from trading on prediction markets under applicable law.

You represent that you are not located in, organized under the laws of, or a resident of any jurisdiction listed in the section titled “Prohibited Jurisdictions” and that you are not subject to any sanctions list maintained by the U.S. Office of Foreign Assets Control (OFAC), the European Union, the United Kingdom, or the United Nations.

03KEYS & CUSTODY

Accounts and wallets

The Services are non-custodial. Trades, deposits, and withdrawals are initiated from a Solana wallet that you control. HighGarden does not store, hold, or have access to your private keys, seed phrases, or signing credentials at any time.

You are solely responsible for the security of your wallet and any device you use to access the Services. Any transaction signed by your wallet is presumed to be authorized by you. HighGarden cannot reverse, cancel, or refund a transaction once it is confirmed on the Solana blockchain.

04OUTCOMES

Market rules and resolution

Each market on HighGarden is governed by a public rule set that defines the YES condition, the NO condition, and the source of truth used to determine the final outcome. The rules are visible on the market page before any trade is placed and are immutable for the lifetime of the market.

Markets resolve when the source of truth confirms the outcome. In rare cases where the source of truth is unavailable, ambiguous, or compromised,HighGarden may apply the documented fallback resolution procedure, which can include market invalidation and pro-rata refund of stake to participants.

Resolution decisions are final. You acknowledge that the interpretation of real-world events for the purposes of market resolution can be a judgment call, and you accept the resolution mechanism described on each market page as a condition of participating.

05COSTS

Fees and settlement

Trades on HighGardenare settled in USDC on Solana. Solana network fees (“gas”) are paid by you in SOL at the time of signing.HighGarden may charge a protocol fee on filled orders or on settlement payouts; the current fee schedule is published on the Services and may be updated from time to time with reasonable notice.

Settlement of a winning position is performed by smart contract once the market is resolved. You are responsible for claiming or withdrawing your settled USDC to your wallet. HighGarden does not guarantee delivery of funds to addresses that are sanctioned, blacklisted by the USDC issuer, or otherwise subject to enforcement action.

06KNOW THE RISK

Risk disclosure

Prediction markets are speculative. You can lose the entire amount you stake on any position. Prices reflect market sentiment, not the actual probability of an outcome, and can move sharply against you. Do not trade with funds you cannot afford to lose.

Additional risks include, without limitation: smart contract risk, oracle risk, network congestion or downtime on Solana, depeg or freezing of USDC, wallet compromise, regulatory changes affecting the legality of prediction markets in your jurisdiction, and resolution disputes. HighGarden does not provide investment, legal, tax, or financial advice.

Prohibited conduct
