ERC7984 Confidential Tokens
Use this skill for work involving confidential fungible tokens built on FHEVM.
When To Use
- Implementing or reviewing an
ERC7984token - Building a confidential wrapper around an ERC20
- Designing wallet, app, or exchange flows for confidential transfers
- Reviewing operator permissions and transfer semantics
- Implementing unwrap flows that need verified plaintext finalization
- Comparing a custom token with OpenZeppelin confidential contracts
Core Mental Model
ERC7984 is not ERC20 with hidden events. It changes the data model and control flow.
- Balances and transfer amounts are encrypted onchain
euint64values are handles to ciphertext, not readable integers

11fhevm-testing
Use when writing, structuring, or debugging tests for FHEVM contracts. Covers mocked mode vs real protocol, Hardhat decrypt helpers, input encryption in tests, and the false-confidence gap between local and testnet behavior.
11fhevm-acl-lifecycle
Use when granting, auditing, or debugging ACL permissions on encrypted handles in FHEVM. Covers FHE.allow, FHE.allowThis, FHE.allowTransient, and the critical rule that new handles do not inherit prior persistent ACL grants.
11fhevm-control-flow
Use when replacing if/else, require, or any conditional logic that depends on encrypted values in FHEVM. Covers FHE.select as the inline branching primitive, fallback semantics on encrypted conditions, and async public decryption when logic must branch back to plaintext state.
11oz-utils-safemath
Use when you need overflow-safe encrypted arithmetic on euint64 values. Covers the OpenZeppelin FHESafeMath library (tryIncrease, tryDecrease, tryAdd, trySub), uninitialized-handle semantics, and when to prefer it over raw FHE.add / FHE.sub.
11fhevm-public-decryption
Use when implementing two-step public decryption for state-changing operations in FHEVM. Covers makePubliclyDecryptable, off-chain proof retrieval, onchain verification with checkSignatures, and the critical single-step unwrap bug.
