Enosys Dex V3

Enosys DEX V3 — Developer Reference

Source-verified from the dex-v3-main repository (Next.js/wagmi frontend). All addresses, ABIs, and reward mechanics confirmed from source code.

Quick orientation

Enosys DEX V3 is a Uniswap V3 fork (CLMM) on Flare Network (chainId 14). Positions are ERC-721 NFTs. Each position can accumulate up to four distinct reward types, each with its own contract and claim method. See references/rewards.md for the full breakdown.

Reward system — how to check and claim

Read references/rewards.md for the full mechanics. Summary:

| Reward type | Contract | Check method | Condition to check | |--------------------|----------------------------|---------------------------------------|-------------------------| | Swap fees | POSITIONMANAGER | tokensOwed0/1 from positions() | Always | | APS incentives | per-pool RewardManager | getUnclaimed([id], 80) | Pool has rewardManagers | | Delegation (FTSO) | FTSOREWARDREDISTRIBUTOR | getUnclaimed([id]) | Pool is native: true | | FlareDrops monthly | MONTHLYREWARD_MANAGER | getUnclaimed([id]) | native + chainId === 14 | | rFLR | n/a — display only | via portal.flare.network | Pool has rflr: true |

> WFLR pool fallback: If a pool is missing from the registry, also run FTSO/Monthly > checks when token0 === WFLR_ADDR || token1 === WFLR_ADDR. This catches WFLR-containing > pools that weren't registered. Always check isNative || isWflrPool. > WFLR_ADDR = '0x1d80c49bbbcd1c0911346656b529df9e5c2f783d' (lowercase for comparison)

Fee growth math (in-range positions)

tokensOwed0/1 from positions() only reflects fees collected at last interaction. For in-range (active) positions, true pending fees must be reconstructed from the pool's fee growth accumulators. Use these helpers (ethers.js v6 / vanilla BigInt):

const U256 = 1n = tickLower ? lowerFGO : u256sub(fgGlobal, lowerFGO)
  const fgAbove = tickCurrent > 128n
}

Required pool contract calls (add to V3_POOL_ABI):

'function feeGrowthGlobal0X128() view returns (uint256)',
'function feeGrowthGlobal1X128() view returns (uint256)',
'function ticks(int24 tick) view returns (uint128 liquidityGross, int128 liquidityNet, uint256 feeGrowthOutside0X128, uint256 feeGrowthOutside1X128, int56 tickCumulativeOutside, uint160 secondsPerLiquidityOutsideX128, uint32 secondsOutside, bool initialized)',

Fetch fgGlobal from pool, feeGrowthOutside0/1X128 from ticks(tickLower) and ticks(tickUpper), then call calcFeeGrowthInside. Compare result against pos.feeGrowthInside0/1LastX128 from positions() using calcPendingFeeAmount.

Claim sequence (run sequentially, continue on individual failure):

1. Fees → collect({ tokenId, recipient, amount0Max: MAX_UINT128, amount1Max: MAX_UINT128 })
2. APS incentives → rewardManager.claim([tokenId], 10, recipient) — gas: min(est*2, 8_000_000)
3. Delegation → ftsoRewardRedistributor.claim([tokenId], recipient) — if native pool
4. Monthly drops → monthlyRewardManager.claim([tokenId], recipient) — if native + chainId 14

Pool registry

Read references/pools.md for the full pool list. Key fields per pool entry:

• native: true — pool earns delegation rewards + FlareDrops
• rflr: true — pool participates in monthly rFLR program (display-only link)
• rewardManagers: [...] — APS incentive managers; always use the last entry as the active one

function findPool(token0, token1, fee, registry) {
  const t0 = token0.toLowerCase(), t1 = token1.toLowerCase()
  return registry.find(p =>
    p.fee === fee &&
    ((p.tokens[0].toLowerCase() === t0 && p.tokens[1].toLowerCase() === t1) ||
     (p.tokens[0].toLowerCase() === t1 && p.tokens[1].toLowerCase() === t0))
  ) || null
}

function getActiveRewardManager(pool) {
  if (!pool?.rewardManagers?.length) return null
  return pool.rewardManagers[pool.rewardManagers.length - 1]
}

Token registry (Flare Mainnet key tokens)

Key constants

const MAX_UINT128            = 2n ** 128n - 1n
const FEE_TIER_LABELS        = { 100: '0.01%', 500: '0.05%', 3000: '0.30%', 10000: '1.00%' }
const INCENTIVE_EPOCHS_CHECK = 80    // getUnclaimed wide window
const INCENTIVE_EPOCHS_CLAIM = 10    // claim() window
const INCENTIVE_GAS_CAP      = 8_000_000n
const RFLR_PORTAL_URL        = 'https://portal.flare.network'
const EXPLORER_BASE          = 'https://flare-explorer.flare.network'

Burn eligibility

A position NFT can only be burned when ALL of the following are true:

• liquidity === 0n
• tokensOwed0 === 0n AND tokensOwed1 === 0n (swap fees)
• getUnclaimed([tokenId], 80) === 0n on its rewardManager (APS)
• ftsoRewardRedistributor.getUnclaimed([tokenId]) === 0n (if native pool)
• monthlyRewardManager.getUnclaimed([tokenId]) === 0n (if native + Flare)

Re-verify by re-calling positions(tokenId) immediately before sending the burn tx.

App architecture pattern (from dex-v3-main)

The existing frontend splits position rows into two components:

• InactivePositionRow — zero-liquidity positions. Uses tokensOwed0/1 directly (no fee growth math). Loads ~3-4 RPC calls total.
• ActivePositionRowFull — positions with liquidity. Runs full fee growth recalculation using feeGrowthGlobal + tick data from pool slot0 and ticks(). Heavier (~15 RPC calls).

The gate component (ActivePositionRow) fetches tokenId + position data (2 calls), checks liquidity === 0n, and routes to the appropriate component. This is the right pattern to replicate in vanilla JS tools.
