Staking Terms of Use

Agreement to Terms

These Staking Terms of Use ("Terms") govern your use of the $POLYBLOCK staking feature provided by Polyblock to obtain or maintain access to Auto Trader. By staking, you enter into a binding agreement with Polyblock and acknowledge that:

• •You are at least 18 years old — or the legal age of majority in your jurisdiction
• •You are not in a restricted jurisdiction — You are not located in or acting from any jurisdiction where such staking or trading is prohibited
• •You have read the disclaimer and terms — You have read the Staking Disclaimer and these Terms in full
• •You accept lock-up and no early withdrawal — You understand tokens are locked for the full period with no early withdrawal
• •You use funds you can afford to lock — You will only stake amounts you can afford to lock for the entire duration

How Staking Works

Staking allows you to lock $POLYBLOCK tokens for a fixed period (15, 30, 60, or 90 days) in exchange for Auto Trader access. Your maximum trade size is determined by your staking tier.

Process

• •Withdrawal address — You provide a Solana wallet address where your tokens will be returned when the stake ends
• •Tier selection — You choose a staking tier (days and corresponding max trade size)
• •Transfer — You send the required $POLYBLOCK amount plus a SOL fee from your own wallet (e.g. Phantom) to your unique staking wallet
• •Confirmation — Once the deposit is confirmed, Auto Trader access is granted according to your tier
• •Return — At the end of the lock period, tokens are automatically returned to your withdrawal address

Lock Period & Return

Staked tokens are locked for the full period. There is no early withdrawal, no pause, and no partial release. At the end of the period, Polyblock will return the staked $POLYBLOCK to the withdrawal address you provided.

• •Correct address — You are solely responsible for providing a correct Solana withdrawal address. Polyblock is not responsible for tokens sent to an incorrect or invalid address
• •One return per stake — Return occurs once per stake at the end of its period
• •Network and timing — Return is subject to Solana network conditions; timing is not guaranteed to the minute

Fees

To stake, you must pay:

• •$POLYBLOCK amount — The minimum staking amount (e.g. 1,000,000 $POLYBLOCK) as shown on the staking page
• •SOL fee — A one-time SOL fee (e.g. 0.1 SOL) to cover network and operational costs. This fee is non-refundable

Fees are displayed on the staking page before you confirm. By completing the stake, you agree to these fees.

Risk Disclosure

Staking and Auto Trader access involve significant risks. By staking, you acknowledge:

• •Token price risk — The value of $POLYBLOCK may go up or down during the lock period
• •No guarantee of access — Auto Trader access is subject to these terms and Polyblock policies; access may be modified or revoked as permitted
• •Technical and smart contract risk — Wallets, backend, and Solana may fail or be delayed; Polyblock is not liable for such events
• •Regulatory risk — Laws may change and affect staking or Auto Trader

Limitation of Liability

To the maximum extent permitted by law, Polyblock shall not be liable for any losses, damages, or expenses arising from staking or Auto Trader access, including but not limited to: loss of tokens, delay in return, loss of access, technical or system failures, third-party (e.g. Solana) issues, or market movements.

You agree to indemnify and hold Polyblock harmless from any claims, damages, or expenses arising from your staking or use of Auto Trader.

Modifications

Polyblock may modify these terms, staking parameters (e.g. tiers, amounts, fees), or Auto Trader access rules at any time. Continued use of staking or Auto Trader after changes constitutes acceptance. For existing stakes, return of tokens will be performed in accordance with the terms in effect at the time of the stake, unless otherwise required by law.
