Codebase Heritage

Hyperdrome is built on the Velodrome/Solidly codebase, one of the most battle-tested ve(3,3) implementations in DeFi:
  • Solidly — Original ve(3,3) AMM by Andre Cronje on Fantom
  • Velodrome — Refined fork on Optimism, the largest DEX by TVL on OP

Timelock

The HyperdromeGovernor multisig includes per-function timelocks:
  • Custom delay per function selector / destination combo
  • Batch transaction execution support
  • Based on 0x’s ZeroExGovernor pattern

​
Key Security Properties

  • Immutable Minter assignment — setMinter() can only be called once on the HDROME token
  • CREATE2 deterministic deployment — Pair addresses are predictable and verifiable
  • veNFT attachment system — Prevents transfer of veNFTs while staked in gauges
  • Epoch-locked votes — Votes cannot be changed mid-epoch, preventing manipulation
  • TWAP oracle — 30-minute observation periods resist price manipulation

​
Solidity Version

All contracts compiled with Solidity 0.8.13 with standard overflow/underflow protections.

​
Test Suite

The protocol includes 21 Foundry test files covering:
  • AMM pair mechanics and fee accounting
  • veNFT lock/unlock/merge operations
  • Emission calculations and decay schedules
  • Gauge staking and reward distribution
  • Voting mechanics and epoch transitions
  • Emergency gauge kill/revive
  • Merkle claim airdrop distribution
  • On-chain governance proposals
  • Anti-wash-trade protection
  • Oracle accuracy and edge cases
