The WeakHands contract is a DeFi mechanism designed to encourage long-term holding of ETH by allowing users to lock their funds until either a specific date is reached, or a target ETH price is achieved. This contract leverages a Chainlink price feed to provide reliable ETH/USD price data for determining withdrawal conditions.
Allows users to deposit ETH into the contract. Multiple deposits are allowed as long as a previous lock hasn't been withdrawn.
Sets the conditions for withdrawal: a future target date and a target ETH price in USD. Can only be set once per lock and requires an existing deposit.
Retrieves the current ETH/USD price from the Chainlink price feed oracle.
Checks if the withdrawal conditions have been met (either target date reached or price threshold exceeded).
Allows users to withdraw their locked ETH if the conditions are met.
Returns complete information about a user's lock, including amount, target date, target price, and status flags.
- Implement partial withdrawal functionality to allow users to withdraw portions of their locked amount while maintaining the remaining balance under the same conditions.
- Add support for multiple concurrent locks per user, enabling different timeframes and price targets for different portions of their holdings.
The contract currently only allows a single deposit and subsequent withdrawal. It would need to be improved to allow a single ETH address to use the contract more once. Perhaps by implementing some sort of reset function or allowing the user to have more than one account somehow...
