On-Chain Verification Scenarios

Each contract was deployed and tested with real transactions on Sepolia.

​
Example Scenarios

Test: set(42) then get()Result: PASS - returned 42
Test: mint(1000000) → verify totalSupply and encrypted balanceResult: PASS - totalSupply=1000000, encrypted balance handle non-zero
Test: createProposal("Fund dev team?", 3600) → verify proposalCountResult: PASS - proposalCount=1
Test: mintTokens(1000) + createProposal() → verify supply and proposalCountResult: PASS - supply=1000, proposalCount=1

​
FHE Operations Verified On-Chain

Type Conversion

  • Plaintext → encrypted (FHE.asEuint32)
  • External input conversion (FHE.fromExternal)
  • Type casting (euint8 → euint32)

Arithmetic

  • FHE.add, FHE.mul
  • Mixed encrypted/plaintext operands

Bitwise & Comparison

  • FHE.and, FHE.or
  • FHE.gt, FHE.ge, FHE.eq

Conditional Logic

  • FHE.select (encrypted ternary)
  • Nested selects

Access Control

  • FHE.allowThis()
  • FHE.allow(ciphertext, address)

Randomness

  • FHE.randEuint32()
  • Bounded random values

Confidential Tokens

  • Encrypted minting
  • Encrypted balance tracking
  • Silent fail transfers

Applications

  • Confidential voting
  • Sealed-bid auctions
  • DAO governance

How to Reproduce

# 1. Ensure .env has PRIVATE_KEY with Sepolia ETH
# 2. Deploy all 35 contracts
npx hardhat run scripts/deploy-all.ts --network sepolia

# 3. Run on-chain verification scenarios
npx hardhat run scripts/test-onchain.ts --network sepolia
