## [Unreleased]

### Added

- Foundry project scaffolding (`forge-std`, CI workflow, `.gitignore`).
- `Love`, an ERC-20 token (`LOVE`, 18 decimals) on OpenZeppelin v5, pegged to
  wETH at 100000 LOVE per wETH. No mint function and no owner: supply moves
  only through the permissionless `deposit(uint256)` and `withdraw(uint256)`,
  so circulating LOVE is always backed by wETH held by the contract.
  `withdraw` reverts with `AmountNotDivisibleByRate` unless the amount is a
  multiple of the rate, keeping the peg free of rounding dust.
- `MockWETH`, a test-only WETH9 stand-in, and tests covering deposit, withdraw,
  the divisibility revert, backing invariants, round-trips, transfers,
  approve/`transferFrom`, reverts and fuzzing.
- Deployment script `script/Love.s.sol`, deploying with CREATE2 through the
  canonical deterministic deployer; salt defaults to `keccak256("LOVE")` and is
  overridable via `SALT`, wETH defaults to the OP-Stack address and is
  overridable via `WETH`. The address embeds the wETH argument, so it is
  identical across chains that share one wETH deployment.
- `predict()` entrypoint printing the deployment address without broadcasting,
  and CREATE2 tests pinning address determinism across chain IDs and its
  dependence on the wETH argument.
- `foundry.toml` with pinned solc 0.8.30, optimizer, fmt rules, fuzz/invariant
  defaults, and Base Sepolia RPC/Etherscan endpoints driven by env vars.
- `script/multichain-check.sh`, deploying `Love` on two local anvil nodes with
  different chain IDs and failing if the two addresses don't match.
- `remappings.txt` for `@openzeppelin/contracts/` and `forge-std/`.
- `.env.example` documenting required environment variables, including `WETH`.
