⚠️ Potential issue | 🟡 Minor

Naming vs. behavior: this is a mintable ERC-20, not a stablecoin.

The contract is named KiiStablecoin and the token is "Kii Dollar / KIIUSD", but there is no peg, collateral, oracle, or stability mechanism — just an owner-mintable ERC-20. For a testnet builder-guide sample this is fine, but consider either:

  • Renaming the contract/symbol to reflect what it actually is (e.g., KiiMintableToken), or
  • Adding a NatSpec note clarifying that the "stablecoin" naming is illustrative only and that no peg mechanism is implemented.

Additionally, mint is unbounded and owner-controlled with no cap or events beyond ERC20's Transfer. For testnet this is acceptable, but worth flagging as a centralization/inflation risk if this contract is ever copy-pasted toward mainnet usage.

In `@testnet_oro/KiiUSD_hunterkurfi.sol` around lines 11 - 25, The contract
KiiStablecoin and ERC20 metadata ("Kii Dollar", "KIIUSD") claim a stablecoin but
implement only an owner-mintable ERC20 (see constructor ERC20("Kii Dollar",
"KIIUSD") Ownable(msg.sender) and function mint(address to, uint256 amount)
public onlyOwner). Either rename the contract and token to something like
KiiMintableToken/KII (or another non-stable name) and update the constructor
metadata, or add a clear NatSpec comment above the contract and the mint()
method stating this is an illustrative, unpegged, owner-mintable token with no
oracle/collateral/stability mechanisms; optionally consider documenting or
implementing supply caps/limits (e.g., a maxSupply check in mint) if you want to
mitigate centralization/inflation risks before reuse in production.
