ApeStake Smart Contract Disclaimer
The ApeStake smart contract (the “Smart Contract”) was developed at the direction of the ApeCoin DAO community pursuant
to a grant by the Ape Foundation.  The grant instructs the development of the Smart Contract and the developer’s user
interface to enable a non-exclusive, user friendly means of access to the rewards program offered to the APE community
by the Ape Foundation pursuant to the specifications set forth in AIPs 21/22. The Smart Contract is made up of free,
public, open-source or source-available software deployed on the Ethereum Blockchain.
Use Disclaimer.
Your use of the Smart Contract involves various risks, including, but not limited to, losses while digital
assets are being supplied and/or removed from the Smart Contract, losses due to the volatility of token price,
risks in connection with your personal wallet access, system failures, opportunity loss while participating in the
Smart Contract, loss of tokens in connection with non-fungible token transfers, risk of cyber attack and/or security
breach, risk of legal uncertainty and/or changes in legal environment, and additional risks which may be based upon
utilization of any third party other than the Smart Contract developer who provides you with access to the Smart
Contract. Before using the Smart Contract, you should review the relevant documentation to make sure you understand
