Understanding these is critical to +building applications that preserve confidentiality. + +## 1. `msg.value` Is Always Public + +`msg.value` is a transaction-level field that is publicly visible on-chain. Assigning +it to a shielded type does **not** retroactively hide the value: + +```solidity +function deposit() public payable { + // WARNING: msg.value was already visible in the transaction. + // Wrapping it in a shielded type does not hide the deposited amount. + suint256 amount = suint256(msg.value); +} +``` + +If your application requires private ETH amounts, you must use a separate wrapped +token design (e.g., a shielded ERC-20) rather than relying on native ETH transfers. + +## 2. Dynamic Shielded Array Lengths + +Dynamic arrays with shielded element types store their length in confidential storage. +However, **an upper bound on the array length may still be observable** through gas +cost analysis. Each `push` or `pop` operation consumes gas proportional to the work +performed, and an observer monitoring gas usage may be able to infer whether elements +were added or removed, and estimate the size of the array over time. + +For arrays of structs with mixed shielded and non-shielded fields (e.g., some +`uint256` and some `suint256`), the length can be deduced by querying the public +storage slots of the non-shielded fields. + +Fixed-length shielded arrays always have a public length by definition, since the +length is part of the type itself. + +## 3. ABI Encoding and Shielded Types + +Shielded types **cannot** be ABI-encoded. The compiler rejects calls such as +`abi.encode(shieldedValue)` to prevent accidental plaintext serialization. + +When explicitly casting a shielded value to its public counterpart (e.g., +`uint256(myShieldedValue)`) and then ABI-encoding the result, be aware that the +value is revealed at the point of casting. Any intermediary or observer of the +execution trace may see the unshielded value. Only cast from shielded to public +when you intentionally want to reveal the data. + +## 4. Shielded Booleans in Branching Conditions + +Using an `sbool` (or an expression producing `sbool`) in control-flow constructs +— `if`, `while`, `for`, ternary `? :`, `require()`, `assert()` — can leak +information. Although the boolean value itself is shielded, the *branch taken* is +observable through: + +- **Gas cost differences** between the two branches +- **State changes** that only occur in one branch +- **Execution traces** visible to sequencers / block builders + +The compiler emits a warning when shielded types are used in branching conditions. + +## 5. `saddress` Member Limitations + +Shielded addresses (`saddress`) only expose the `.code` and `.codehash` members. +Other address members (`.balance`, `.transfer()`, `.send()`, `.call()`, etc.) +require casting to a public `address` first: + +```solidity +saddress secret = saddress(someAddr); +// secret.balance; // ERROR +// address(secret).balance; // OK — but reveals the address +``` + +Accessing these members inherently requires revealing the address on-chain, which +is why the cast must be explicit. + +## 6. Literal Values Leak During Deployment + +Literal values that are converted to shielded types at contract construction time +will be visible in the deployment bytecode: + +```solidity +suint256 private constant SECRET = suint256(42); // 42 is visible in deploy tx +``` + +The compiler warns when it detects literals being directly converted to shielded +types.
