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

• Direct money access detected (high risk: 1.00). The skill is explicitly targeted at writing Solidity smart contracts that handle tokens and ETH and references concrete blockchain/payment-related libraries and tooling. It mandates use of SafeERC20 and ReentrancyGuard for any contract that transfers tokens/ETH, references PaymentSplitter (a payments-splitting library), ERC-4626 (vaults), stablecoin templates, and account abstractions (ERC-4337). It also mentions Foundry cast CLI (call / send) and deployment/interaction scripts (*.s.sol) for on-chain calls. These are specific crypto/blockchain tools and patterns that enable signing/sending or managing on-chain value, so the skill grants direct crypto financial execution capability.
