Core Capabilities

Locking HYDX

• Lock HYDX to receive veHYDX (vote-escrowed HYDX)
• Receive an NFT representing your locked position
• Gain voting power starting next epoch
• Rolling locks (Type 1) provide maximum voting power
• Auto-extends to maintain 2-year lock with no manual management
• Earning power = 1.3x voting power for fee distributions

Reference: references/locking.md

Voting on Pools

• Vote to allocate voting power across liquidity pools
• Direct HYDX emissions based on your votes
• Earn fees from supported pools
• Optimize for maximum fee returns
• Natural language voting by pool name

Reference: references/voting.md

Single-Sided Liquidity (ICHI Vaults)

• Deposit a single token into an auto-managed vault
• Earn oHYDX yields on your deposited value
• Vault manages both sides of the liquidity position
• Withdraw with up to 70/30 split (deposit token / counter token)
• No need to source both sides of a pair

Reference: references/single-sided-liquidity.md

Claiming and Managing Rewards

• Check unclaimed oHYDX across all incentive campaigns
• Claim all eligible rewards in a single transaction
• Convert oHYDX into a veHYDX lock position via exerciseVe
• Exercising oHYDX requires a discounted ETH payment and produces a rolling veHYDX lock

Reference: references/rewards.md

Contracts (Base Mainnet)

Pool Information API

Get current liquidity pool data:

bankr agent "What are the top Hydrex pools by projected fees?"
bankr agent "Show me all Hydrex liquidity pools with their voting weights"

Key fields for voting optimization:

• address — Pool address (voting target)
• title — Pool name (e.g., "HYDX/USDC")
• gauge.projectedFeeInUsd — Primary optimization metric
• gauge.liveVotingWeight — Current competition for fees
• gauge.votingAprProjection — Expected APR from voting

Efficiency formula: projectedFeeInUsd / liveVotingWeight = fee revenue per vote

Common Workflows

First-Time Setup

1. Get HYDX — Acquire HYDX tokens on Base
2. Approve HYDX — Approve veHYDX contract to spend HYDX
3. Lock HYDX — Create rolling lock (Type 1) for voting power
4. Wait for epoch — Voting power activates next epoch (~weekly)
5. Vote — Allocate voting power to pools

Example:

# Step 1: Check HYDX balance
"What's my HYDX balance on Base?"

# Step 2 & 3: Approve and lock in one go
"Lock 1000 HYDX on Hydrex with rolling lock"

# Step 4: Wait for next epoch (typically next Thursday 00:00 UTC)

# Step 5: Vote optimally
"Vote optimally on Hydrex to maximize fees"

Optimized Voting

When you want maximum returns:

Vote optimally on Hydrex to maximize my fee earnings

Bankr will:

1. Fetch all pools from API
2. Calculate efficiency (fees per vote) for each pool
3. Rank pools by efficiency
4. Allocate votes to top pools
5. Execute vote transaction

Named Pool Voting

Vote by pool name instead of addresses:

Vote 100% on HYDX/USDC on Hydrex

Vote 60% on HYDX/USDC and 40% on cbBTC/WETH on Hydrex

Vote 33/33/34 on HYDX/USDC, cbBTC/WETH, and USDC/USDbC on Hydrex

Changing Votes

Reallocate your voting power:

Change my Hydrex vote to 100% on cbBTC/WETH

This will reset current votes and apply new allocation.

Optimization Strategies

Simple Strategy

Vote 100% on the pool with highest projectedFeeInUsd / liveVotingWeight ratio.

Example:

Vote on the single best Hydrex pool by fees

Balanced Strategy

Split votes equally across top 3-5 efficient pools for diversification.

Example:

Vote equally on top 3 Hydrex pools by projected fees

Weighted Strategy

Allocate votes proportional to efficiency scores.

Example:

Vote on Hydrex pools weighted by their fee efficiency

Understanding Voting Power

How Voting Power Works

1. Lock HYDX → Receive veHYDX NFT
2. veHYDX amount = Your voting power
3. Rolling locks (Type 1) = Maximum voting power with auto-extension
4. Earning power = 1.3x voting power (used for fee distributions)
5. Next epoch = Voting power activates
6. Vote allocation = Direct emissions to pools

Checking Your Power

# Check voting power
bankr agent "What's my Hydrex voting power?"

# Check earning power (1.3x voting power)
bankr agent "What's my Hydrex earning power?"

# Check veHYDX NFT balance
bankr agent "Show my veHYDX NFT balance"

# Check a specific NFT's earning power
bankr agent "How much earning power does my veHYDX NFT #5 have?"

Display to users: Show earning power (voting power × 1.3) when discussing fee earnings, as this is what determines your share of distributions.

Vote Proportions

Vote weights are in basis points (10000 = 100%):

Proportions must sum to exactly 10000.

Epoch System

Hydrex operates on epochs:

• Duration: Typically 1 week
• Voting power activation: Next epoch after locking
• Vote changes: Respect vote delay between changes
• Epoch boundary: Usually Thursday 00:00 UTC

Example Prompts

Locking

• "Lock 1000 HYDX on Hydrex with rolling lock"
• "Create veHYDX rolling lock with 500 HYDX on Base"
• "Add 250 HYDX to my veHYDX NFT #1"

Voting

• "Vote optimally on Hydrex"
• "Vote 50/50 on HYDX/USDC and cbBTC/WETH on Hydrex"
• "Allocate my votes to top 3 Hydrex pools by fees"
• "Change my Hydrex vote to 100% on HYDX/USDC"

Queries

• "What's my Hydrex earning power?"
• "Show me the best Hydrex pools to vote for"
• "How much earning power does my veHYDX NFT #5 have?"

Single-Sided Liquidity

• "What single-sided liquidity vaults are available on Hydrex?"
• "What single-sided vaults can I deposit BNKR into on Hydrex?"
• "Deposit 500 BNKR into the BNKR/WETH single-sided vault on Hydrex"
• "Show my Hydrex single-sided liquidity positions"
• "Withdraw my BNKR/WETH single-sided position on Hydrex"

• "Claim all my unclaimed Hydrex incentives"
• "What's my oHYDX balance on Base?"
• "Convert my oHYDX to veHYDX on Hydrex"
• "Exercise my oHYDX rewards into veHYDX"

Tips

For New Users

• Start small: Lock a small amount first to learn the flow
• Rolling locks: Use Type 1 for maximum voting power with auto-extension
• Wait for epoch: Voting power activates at next epoch boundary
• Let Bankr optimize: "Vote optimally" handles everything automatically
• Earning power: Remember your fee earnings are based on 1.3x your voting power

For Active Voters

• Track efficiency: Monitor projectedFeeInUsd / liveVotingWeight
• Diversify votes: Split across 3-5 pools to reduce risk
• Watch bribes: Check API for additional incentive opportunities
• Respect delays: Vote delay prevents too-frequent changes
• Use pool names: Easier than remembering addresses

For Maximizers

• Efficiency > absolute fees: $5k fees with 100k weight beats $10k fees with 500k weight
• Use earning power: Calculate earnings with 1.3x voting power for accurate projections
• Rebalance periodically: Pool efficiency changes over time
• Consider liquidity: High-volume pools may be more stable
• Factor in bribes: Check gauge.bribes for extra rewards
• Rolling locks: Type 1 automatically maintains 2-year duration for max power

Natural Language Voting Guide for Bankr

When processing Hydrex voting requests:

1. Fetch pool data from https://api.hydrex.fi/strategies
2. Get user earning power: Query voting power, multiply by 1.3
3. Parse user intent:
   • Pool names → Look up addresses in API (title field)
   • "Optimally" / "maximize fees" → Calculate efficiency rankings
   • Percentages → Convert to basis points (60% = 6000)
4. Validate proportions sum to 10000
5. Execute vote via voter contract 0xc69E3eF39E3fFBcE2A1c570f8d3ADF76909ef17b

When displaying earnings projections, always use earning power (voting power × 1.3), not raw voting power.

Example optimization logic:

curl -s https://api.hydrex.fi/strategies | jq '[.[] |
  select(.gauge.projectedFeeInUsd != null and .gauge.liveVotingWeight > 0) |
  {
    address,
    title,
    efficiency: (.gauge.projectedFeeInUsd / .gauge.liveVotingWeight)
  }
] | sort_by(-.efficiency) | .[0:3]'

💡 Pro Tip: Efficiency (fees per vote) matters more than absolute fees. Say "vote optimally on Hydrex" and let Bankr handle the math. Remember your earnings are based on earning power (1.3x voting power).

⚠️ Important: Rolling locks (Type 1) automatically extend to maintain 2-year duration. This maximizes your voting power without manual management.

🚀 Quick Win: Lock HYDX with rolling lock, wait for next epoch, then say "vote optimally on Hydrex to maximize fees" — Bankr calculates using your earning power and does the rest.
