This is a Solidity contract that implements a Know Your Customer (KYC) system for a blockchain-based application. The contract allows users to create accounts, lock funds, and securely transfer funds to other verified accounts.
- Account Creation: Users can create new accounts by sending Ether to the contract. The contract will automatically create a new account with the user's address, locked balance, KYC status, and transaction count.
- Balance Withdrawal: Users can withdraw their locked balance from the contract.
- Account Removal: Users can remove their account from the contract, but only if their locked balance is zero.
- KYC Verification: The contract provides a
kycCheck()
function that allows users to check the KYC status of a given address. - Secure Transfer: The contract provides a
secureTransfer()
function that allows users to transfer funds to other verified accounts.
The contract emits the following events:
newAccountListed
: Emitted when a new account is created.balanceUnlocked
: Emitted when a user withdraws their locked balance.accountRemoved
: Emitted when a user removes their account.accountUpdated
: Emitted when an account is updated.transferSuccess
: Emitted when a successful transfer is made.
The contract provides the following functions:
addNewAccount(address requester, uint valueToLock)
: Adds a new account to the contract.transferBack(uint backValue)
: Allows a user to withdraw their locked balance.removeAccount()
: Allows a user to remove their account from the contract.userView()
: Allows a user to view their account details.kycCheck(address target)
: Allows a user to check the KYC status of a given address.secureTransfer(address destination, uint sendValue)
: Allows a user to securely transfer funds to another verified account.fallback()
: Allows users to create new accounts by sending Ether to the contract.
To use this contract, you can deploy it to a Ethereum-based blockchain and interact with it using a Solidity-compatible development environment, such as Remix or Truffle.
