+# Solidity & ZkSync Development Standards
+
+## Toolchain & Environment
+- **Primary Tool**: `forge` (ZkSync fork). Use for compilation, testing, and generic scripting.
+- **Secondary Tool**: `hardhat`. Use only when `forge` encounters compatibility issues (e.g., complex deployments, specific plugin needs).
+- **Network Target**: ZkSync Era (Layer 2).
+- **Solidity Version**: `^0.8.20` (or `0.8.24` if strictly supported by the zk-compiler).
+
+## Modern Solidity Best Practices
+- **Safety First**:
+  - **Checks-Effects-Interactions (CEI)** pattern must be strictly followed.
+  - When a contract requires an owner (e.g., admin-configurable parameters), prefer `Ownable2Step` over `Ownable`. Do **not** add ownership to contracts that don't need it — many contracts are fully permissionless by design.
+  - Prefer `ReentrancyGuard` for external calls where appropriate.
+- **Gas & Efficiency**:
+  - Use **Custom Errors** (`error MyError();`) instead of `require` strings.
+  - Use `mapping` over arrays for membership checks where possible.
+  - Minimize on-chain storage; use events for off-chain indexing.
+
+## Testing Standards
+- **Framework**: Foundry (Forge).
+- **Methodology**:
+  - **Unit Tests**: Comprehensive coverage for all functions.
+  - **Fuzz Testing**: Required for arithmetic and purely functional logic.
+  - **Invariant Testing**: Define invariants for stateful system properties.
+- **Naming Convention**:
+  - `test_Description`
+  - `testFuzz_Description`
+  - `test_RevertIf_Condition`
+
+## ZkSync Specifics
+- **System Contracts**: Be aware of ZkSync system contracts (e.g., `ContractDeployer`, `L2EthToken`) when interacting with low-level features.
+- **Gas Model**: Account for ZkSync's different gas metering if performing low-level optimization.
+- **Compiler Differences**: Be mindful of differences between `solc` and `zksolc` (e.g., `create2` address derivation).

+
+## L1-Only Contracts (No --zksync flag)
+
+The following contracts use opcodes/patterns incompatible with ZkSync Era and must be built/tested **without** the `--zksync` flag:
+
+- **SwarmRegistryL1**: Uses `SSTORE2` (relies on `EXTCODECOPY` which is unsupported on ZkSync).
+
+For these contracts, use:
+
+```bash
+forge build --match-path src/swarms/SwarmRegistryL1.sol
+forge test --match-path test/SwarmRegistryL1.t.sol
+```
