The complete guide to WOOfi Finance — the decentralised trading and yield platform built by WOO Network that uses a proprietary synthetic Proactive Market Making (sPMM) algorithm to deliver CEX-quality prices on-chain, eliminating the price impact and spread inefficiencies of traditional AMMs. Understand how sPMM achieves near-zero slippage by sourcing professional market-maker liquidity from WOO Network's institutional order book, how WOOfi Earn vaults let anyone deposit stablecoins and blue-chip assets for competitive yield, how WOO token staking unlocks fee rebates and enhanced vault APY, and how WOOfi operates across 10+ EVM chains with unified cross-chain swap routing.
Connect your EVM wallet on any of WOOfi's 10+ supported chains — Ethereum, Arbitrum, BNB Chain, Polygon, Avalanche, Optimism, Fantom, and more. WOOfi's interface auto-detects your chain and shows available trading pairs and vault options.
Execute token swaps through WOOfi's sPMM algorithm — which sources pricing from WOO Network's institutional market-making infrastructure and on-chain liquidity simultaneously. For major pairs, this typically delivers tighter spreads and lower price impact than standard AMM DEXs.
Deposit USDC, USDT, WOO, BTC, ETH, or other supported assets into WOOfi Earn vaults to earn yield. Vaults deploy capital into WOO Network's lending operations and optimised DeFi strategies — delivering competitive APY without manual management.
Stake WOO tokens to receive trading fee rebates on all WOOfi swaps — reducing your effective trading cost to near-zero. WOO stakers also access boosted vault APY and governance participation in WOO Network's DAO.
WOOfi is the decentralised finance arm of WOO Network — a crypto liquidity network founded in 2019 that combines institutional market-making with retail trading products. WOO Network operates both a centralised exchange (WOO X) and WOOfi — its on-chain DEX and yield platform — sharing liquidity infrastructure between both.
The key insight behind WOOfi is that traditional AMM DEXs price trades using only the liquidity in their own on-chain pools — creating price impact and spread costs proportional to pool depth. WOOfi's sPMM algorithm supplements on-chain liquidity with WOO Network's institutional market-making data, delivering pricing closer to CEX mid-price than most on-chain alternatives.
Get near-CEX prices on major token pairs without leaving your wallet. WOOfi's sPMM delivers tighter spreads than standard AMMs on large trades for major pairs like ETH/USDC, BTC/USDC, and WOO pairs. Staking WOO reduces trading fees to near-zero on top of the already competitive pricing.
WOOfi Earn offers stablecoin and blue-chip asset vaults with APY sourced from WOO Network's institutional lending and optimised DeFi strategies. Single-asset deposits with auto-compounding — no LP complexity or impermanent loss exposure.
Stake WOO on WOOfi to earn fee rebates on every swap, boosted vault APY, and governance rights. The WOO staking model aligns token holders with platform trading volume — more volume means more fee redistribution to stakers.
WOOfi exposes a developer API and router that other protocols use to source WOOfi's sPMM pricing for their own swaps. Many DeFi aggregators (1inch, Paraswap, OpenOcean) route through WOOfi when it offers best execution — making WOOfi a backend liquidity source across the DeFi ecosystem.
Synthetic Proactive Market Making (sPMM) is WOOfi's proprietary pricing algorithm — the core innovation that distinguishes it from standard AMMs like Uniswap or Curve.
sPMM uses a parametric price function informed by WOO Network's off-chain market-making data — specifically the mid-price (p), spread (s), and slippage coefficient (k) for each pair. These parameters are updated continuously by WOO Network's market-making engine, keeping on-chain prices aligned with institutional quote streams rather than just pool supply/demand ratios.
sPMM's advantage is most significant on large trades for major liquid pairs (ETH, BTC, WOO against USDC/USDT). For small trades (<$1,000) on standard pairs, the price difference vs Uniswap V3 may be negligible. For long-tail tokens with low CEX liquidity, sPMM may not have superior data to draw from. Always compare with a DEX aggregator quote for the best overall execution.
WOOfi Swap is the trading interface powered by sPMM — supporting spot swaps on 10+ chains and cross-chain swaps between them via Stargate or native bridge integrations.
| Feature | Details | User benefit |
|---|---|---|
| Spot swaps | sPMM-priced swaps for major token pairs on each supported chain | Near-CEX pricing with DeFi custody — no KYC, no withdrawal delays |
| Cross-chain swaps | Swap and bridge in a single transaction — e.g. ETH on Arbitrum → USDC on BNB Chain | Eliminates the multi-step bridge-then-swap workflow; single confirmation UX |
| Trading fee | 0.025%–0.1% depending on pair and WOO staking tier | Lower than most AMM DEXs (Uniswap charges 0.05%–1% depending on pool) |
| WOO staker rebate | WOO stakers receive up to 100% fee rebate on eligible swap volume | Effective 0% trading fee for WOO stakers — significant saving for active traders |
| Aggregator sourcing | WOOfi quotes are available via 1inch, Paraswap, and OpenOcean — routed automatically when WOOfi offers best execution | Even non-WOOfi users benefit from WOOfi's pricing via DEX aggregators |
WOOfi Earn is a single-asset yield platform where users deposit tokens and earn APY without LP complexity, impermanent loss, or active management. Vaults deploy capital into WOO Network's lending operations and optimised DeFi strategies.
WOO is the native token of WOO Network — the central utility and governance token across both WOO X (CEX) and WOOfi (DEX), creating a unified token economy across the entire ecosystem.
| Function | How WOO is used | Benefit |
|---|---|---|
| Trading fee rebates (WOOfi) | Stake WOO to receive rebates on WOOfi swap fees — up to 100% rebate at highest tier | Effectively 0% trading fee for large WOO stakers — significant for high-volume traders |
| Vault APY boost | WOO stakers receive higher base APY on WOOfi Earn vaults across all assets | Enhanced yield on existing DeFi positions for WOO holders |
| WOO X fee discounts (CEX) | Hold WOO on WOO X to reduce trading fees on the centralised exchange | Unified token utility across both CEX and DEX — rare in crypto |
| Governance (WOO DAO) | WOO stakers vote on protocol parameters, fee structures, and treasury allocation | Influence over both WOOfi and WOO Network's operational direction |
| Market maker collateral | WOO Network's market-making operations use WOO as part of their collateral pool | Creates structural demand for WOO from the institutional operations that power sPMM |
Total supply: 2,900,000,000 WOO (2.9 billion). Verify via official WOO Network documentation.
WOOfi's cross-chain swap combines Stargate Finance's bridge infrastructure with WOOfi's sPMM DEX in a single atomic flow. When you select "ETH on Arbitrum → USDC on BNB Chain," WOOfi routes through Stargate to bridge and simultaneously executes the destination swap — one transaction from your perspective, fully handled by the protocol on the backend.
Cross-chain swap costs include: WOOfi's swap fee on both legs (with WOO staker rebates applied), the Stargate bridge fee, and gas on both source and destination chains. The WOOfi interface shows the full cost breakdown before confirmation — including expected received amount on destination. Compare with manual bridge-then-swap to verify the cross-chain route is competitive.
| Risk | Level | Mitigation |
|---|---|---|
| Smart-contract exploit | Medium | WOOfi contracts audited by multiple firms; bug bounty programme active; significant TVL creating ongoing scrutiny incentive from the security community |
| sPMM oracle manipulation | Medium | sPMM price parameters are updated by WOO Network's market-making system — a centralised oracle risk. If the price feed is manipulated, trades could execute at incorrect prices. WOOfi has circuit breakers and slippage limits as guards |
| Earn vault strategy risk | Medium | WOOfi Earn vaults deploy capital into DeFi strategies — underlying strategy exploits can affect vault principal. Stablecoin vaults have lower strategy risk than more complex yield strategies |
| WOO Network counterparty risk | Medium | WOOfi's sPMM pricing depends on WOO Network's operational integrity as a market maker. WOO Network is a regulated, institutional entity — but counterparty concentration is a real risk vs fully decentralised AMMs |
| Cross-chain bridge risk | Medium | Cross-chain swaps use Stargate — inherit Stargate's bridge risks. Bridges are the highest-risk DeFi category; use cross-chain swaps for necessary cross-chain transfers, not as primary trading strategy |
| Phishing / fake WOOfi sites | High (user-controlled) | Bookmark fi.woo.org; verify domain every session; never connect wallet to sites reached via social media links or DMs claiming to be WOOfi |

WOOfi is a DEX and yield platform built by WOO Network that uses a synthetic Proactive Market Making (sPMM) algorithm — not a traditional AMM like Uniswap. Uniswap prices trades using only the liquidity in its own on-chain pools, creating price impact that scales with trade size. WOOfi's sPMM supplements on-chain liquidity with pricing data from WOO Network's institutional market-making operation, delivering tighter spreads on major pairs — particularly on large trades. Additionally, WOOfi offers single-asset yield vaults (WOOfi Earn) and WOO token fee rebates that Uniswap doesn't have.
sPMM (synthetic Proactive Market Making) is WOOfi's proprietary pricing algorithm. It uses a parametric price function with three key parameters — mid-price (p), spread (s), and slippage coefficient (k) — that are updated continuously by WOO Network's institutional market-making engine. Rather than pricing purely from pool supply/demand ratios, sPMM anchors on-chain prices to institutional order book data. The result is spreads and price impact closer to CEX quality, especially for major liquid pairs where WOO Network's market-making data is most relevant.
WOOfi Earn vaults accept single-asset deposits (USDC, USDT, ETH, BTC, WOO) and deploy the capital into yield-generating strategies — including WOO Network's institutional lending operations and optimised DeFi strategies. Depositors receive an interest-bearing token representing their vault share, and rewards auto-compound without manual claiming. You can withdraw at any time. APY is variable and displayed live in the WOOfi interface. WOO stakers receive enhanced APY across all vaults.
Stake WOO tokens on WOOfi to enter the fee rebate programme. Different staking tiers (based on WOO staked amount) receive different rebate percentages — ranging from partial rebates at lower tiers to up to 100% fee rebate at the highest tier. The rebate is credited in WOO tokens or deducted from fee calculations depending on the implementation. For high-frequency traders, the effective trading cost with WOO staking can approach zero — making WOOfi among the cheapest execution venues in DeFi for those who hold WOO.
In March 2023, WOOfi suffered a flash loan exploit on Arbitrum where an attacker manipulated the sPMM price oracle, resulting in approximately $8.5M in losses from the liquidity pool. WOO Network reimbursed affected liquidity providers in full. Following the incident, WOOfi implemented Chainlink price reference validation as a secondary oracle check, tightened circuit breakers, and improved slippage limits. The exploit is documented in WOOfi's public post-mortem. Since the fix, WOOfi has operated without a repeat incident — but the oracle risk is real and users should understand it before using WOOfi for large positions.
WOOfi's cross-chain swap combines Stargate Finance's bridge with WOOfi's sPMM DEX in a single transaction. You select source chain, source token, destination chain, and destination token in WOOfi's interface. WOOfi handles the bridge routing (via Stargate) and the destination swap automatically — you sign one transaction on the source chain and receive your destination tokens without managing the bridge step separately. The full cost (swap fees on both legs + bridge fee + gas) is shown before confirmation. Cross-chain swaps typically complete in 2–10 minutes depending on source chain finality.
WOOfi supports Ethereum, Arbitrum One, Optimism, BNB Chain, Polygon, Avalanche, Fantom, zkSync Era, Base, Linea, and additional chains with ongoing expansion. The WOOfi interface shows all currently active chain deployments — check fi.woo.org for the current supported chain list. WOOfi Earn vault availability varies by chain — some vaults are chain-specific while others are available across multiple networks.
GMX offers yield via its GLP token (providing liquidity to its perp DEX), while WOOfi Earn offers single-asset vaults. Key differences: GMX's GLP yield is higher but carries exposure to trader P&L (if traders profit, GLP holders lose) and impermanent loss from the multi-asset basket. WOOfi Earn vaults are single-asset with no impermanent loss — USDC deposited always returns USDC (plus yield). WOOfi's stablecoin vault APY is typically comparable to or above GMX GLP stablecoin APY without the trader counterparty risk. For risk-adjusted stablecoin yield, WOOfi Earn is generally the more conservative choice.
WOOfi and WOO X are both products of WOO Network — they share the WOO token ecosystem and underlying liquidity infrastructure. WOO X is the centralised exchange for users who prefer CEX trading with KYC; WOOfi is the DeFi arm for users who want self-custodial trading. The WOO token provides utility on both platforms — fee discounts on WOO X and fee rebates on WOOfi — making it one of the few tokens with genuine dual-venue utility. WOOfi's sPMM pricing draws from the same market-making intelligence that powers WOO X's institutional order book, bridging the CEX-DeFi pricing gap.
