Bribes & Rewards

​
Reward Flow

The Hyperdrome reward system has three distinct streams flowing to different participants:
  1. LP Emissions — The Minter creates HDROME each epoch. The Voter contract distributes it to gauges based on veHDROME vote weights. LPs staked in gauges earn these emissions on a per-second basis proportional to their share of the gauge.
  2. Trading Fees + External Bribes → Voters — 100% of trading fees from each pool and any external bribes deposited for that pool’s gauge flow to the veHDROME holders who voted for it. These are claimable after each epoch flip.
  3. Rebases → veHDROME Holders — The RewardsDistributor sends anti-dilution HDROME rebases to all veHDROME holders proportional to their voting power, protecting lockers from emission dilution.

External Bribes

Bribe Marketplace
External bribes allow protocols to incentivize veHDROME voters to direct emissions toward specific pools. This is the primary mechanism for protocols to acquire deep liquidity on Hyperdrome.
1

Deposit Bribe

A protocol deposits tokens into the ExternalBribe contract for a specific gauge before the epoch flip.
2

Bribe Activates

At epoch flip, the bribe becomes visible to voters. veHDROME holders factor bribe value into their voting decisions for the current epoch.
3

Voters Earn

After the epoch ends, voters who allocated votes to that gauge can claim their proportional share of the bribe based on their vote weight.

​
Bribe Efficiency

  • Protocols typically acquire 2−5ofliquidityforevery2-5 of liquidity for every 1 spent on bribes
  • Bribe ROI varies by epoch — lower total vote weight means higher per-vote returns
  • Consistent bribing across multiple epochs builds sustained liquidity depth
  • Up to 16 different reward tokens can be used as bribes per gauge

​
Internal Bribes (Trading Fees)

Internal bribes are not deposited by external parties — they are the trading fees generated by each pool. 100% of swap fees are automatically routed to the InternalBribe contract for that pool’s gauge. veHDROME voters who voted for the gauge claim these fees after each epoch flip. Higher-volume pools generate more internal bribes, making them attractive voting targets.

​
Rebases

Rebases are anti-dilution rewards distributed to all veHDROME holders via the RewardsDistributor contract. When new HDROME is minted each epoch, a proportional amount is distributed as rebases to prevent voting power dilution. The rebase amount scales with the ratio of locked HDROME to total circulating supply — more locking means higher rebases.
