MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill is specifically about Solidity smart contract security and includes explicit contract functions and tests that transfer cryptocurrency: a payable deposit() and a withdraw(uint256) that sends ETH via msg.sender.call{value: amount}(""), plus Hardhat tests that deposit/withdraw and trigger value transfers and attacker contracts. These are concrete crypto/blockchain fund-transfer operations (sending/receiving ETH), so the skill grants direct financial execution capability.
