The Liquidity Hub on Solana. Swap · Bridge · Pool · Stake · Earn — all in one protocol.

HumidiFi is a full-stack exchange protocol built on Solana. It combines asset swapping, cross-chain bridging, concentrated liquidity pools, SOL staking, and yield rewards in a single non-custodial platform. Available at humidifi-dex.net.

Connect your Solana wallet (Phantom, Solflare, Backpack, or Ledger), select your input and output assets, enter the amount, review the route and price impact, and click Swap. HumidiFi's smart router automatically finds the best price across all Solana AMMs. Transactions confirm in under 400 milliseconds.

HumidiFi charges a base swap fee of just 0.04% on all swaps — the lowest fee of any major DEX on Solana. Fee tiers for liquidity pools range from 0.01% for stable pairs to 0.25% for volatile pairs. All fees are distributed to liquidity providers and HMDF stakers — zero protocol treasury cut.

Yes. HumidiFi has been audited by 5 independent security firms: Otter Security, Halborn, OtterSec + Neodyme, Trail of Bits, and Sec3. All smart contracts are open-source and formally verified. The protocol has secured over $640M TVL without any security incidents. A $10M bug bounty is active.

HumidiFi supports all major Solana wallets: Phantom, Solflare, Backpack, Glow, Coin98, Trust Wallet, Ledger hardware wallet, and any wallet compatible with the Solana Wallet Adapter standard. Mobile users can connect via WalletConnect.

HumidiFi uses a Concentrated Liquidity Market Maker (CLMM) model. Instead of spreading liquidity across all prices, LPs choose a specific price range to concentrate their capital. This means higher fee earnings per dollar of liquidity provided — typically 5–10× more efficient than traditional AMMs. You can earn up to 31% APR in the top pools.

HMDF is the native governance and reward asset of HumidiFi. You earn HMDF by trading on the platform (trading rewards), providing liquidity (LP rewards), referring users (referral rewards), and participating in governance. HMDF can be staked for additional yield and locked as veHMDF for boosted APY and voting power.

HumidiFi offers three staking products: (1) hSOL Liquid Staking — stake SOL and receive hSOL liquid staking assets at 7.2% APY with instant unstaking. (2) HMDF Vault — stake HMDF for 18.5% APY with a 14-day lock. (3) veHMDF Governance — lock HMDF for up to 4 years for 12.1% APY plus voting power and fee revenue share.

hSOL is HumidiFi's liquid staking asset representing staked SOL. It appreciates in value relative to SOL as staking rewards accrue. Unlike native staked SOL, hSOL is fully liquid — you can use it as collateral on lending protocols, provide hSOL/SOL liquidity, bridge it cross-chain, or swap it back to SOL instantly at any time.

HumidiFi's bridge uses Wormhole Guardian network as the base security layer, combined with HumidiFi's optimized routing for best rates. You can bridge SOL, USDC, USDT, wBTC, wETH and more between Solana, Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, and 5+ other networks. Bridge transfers typically complete in 10–20 minutes.

The HumidiFi bridge supports 12+ networks including Solana, Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Fantom, Sui, Aptos, and NEAR. New chains are added regularly through governance proposals. All bridge routes can be checked in the Bridge tab of the app.

HumidiFi's Smart Order Routing (SOR) engine queries liquidity across all major Solana AMMs — including HumidiFi's own CLMM pools, Raydium, Orca, Meteora, and others — then splits and routes orders for optimal price execution. This aggregation means you always get better prices on HumidiFi than on any single AMM alone.

Yes. HumidiFi integrates with Jito's MEV-protection infrastructure on Solana, which routes transactions through a private mempool to prevent sandwich attacks and front-running. Combined with Solana's parallel transaction processing, HumidiFi offers strong MEV-resistance without sacrificing execution speed.

HumidiFi's referral program rewards you with 20% of the trading fees generated by users you refer, paid in real-time in HMDF. There's no cap — top referrers earn thousands of dollars monthly. Generate your referral link from the Rewards tab once you connect your wallet. Referral rewards are claimable at any time.

Navigate to the Pools tab, select an existing pool or create a new one. Choose your price range (for concentrated liquidity) and deposit amounts. Your LP position is represented as an NFT on Solana. You start earning fees and HMDF rewards immediately with no lock-up required.

HumidiFi supports 400+ Solana assets, including SOL, USDC, USDT, wBTC, wETH, JUP, BONK, PYTH, WIF, RAY, ORCA, mSOL, stSOL, hSOL, and thousands more. Any SPL asset can be traded. New assets are available as soon as their pool is created — no permission required.

While Raydium and Orca are primarily AMMs and Jupiter is a swap aggregator, HumidiFi is a unified protocol combining aggregated swaps, CLMM pools, cross-chain bridging, liquid staking, and governance — all in one interface. HumidiFi aggregates across other DEXs including Raydium and Orca to ensure best prices, while offering unique native liquidity pools and the highest LP APRs.

Yes. HumidiFi supports on-chain limit orders for all pairs. Set your desired price and the order executes automatically when the market reaches your target. Limit orders are non-custodial and can be cancelled at any time. They're powered by Solana's OpenBook order book integrated within HumidiFi's routing engine.

Yes. HumidiFi is fully responsive and works in any mobile browser. For the best experience, use Phantom or Solflare's built-in browser on iOS or Android. HumidiFi also works seamlessly inside Backpack's integrated browser. A native iOS and Android app is on the roadmap.

veHMDF (vote-escrowed HMDF) is received when you lock HMDF for a chosen period (1 week to 4 years). The longer you lock, the more veHMDF you receive. veHMDF earns boosted APY (up to 2.5× base rates), protocol fee revenue share (50% of all fees), and voting power over pool emission allocations and governance proposals.

Yes. HumidiFi is a fully on-chain, non-custodial protocol with no central intermediary. Smart contracts are deployed on Solana mainnet, are open-source on GitHub, and have no admin upgrade keys. Protocol governance is entirely controlled by veHMDF holders. The team cannot access user funds or modify contracts without a governance vote and 48-hour timelock.

Solana processes blocks approximately every 400 milliseconds, making HumidiFi trades among the fastest available. Swap transactions typically confirm within 1–3 blocks (0.4–1.2 seconds). This compares to 12–30 seconds for Ethereum DEXs and 3–5 seconds for BNB Chain DEXs. There's no mempool congestion on Solana.

Solana base network fees are approximately $0.00025 per transaction — making each HumidiFi swap cost a fraction of a cent in gas. This is up to 10,000× cheaper than Ethereum DEX gas fees. Combined with HumidiFi's 0.04% trading fee, the total cost of a $1,000 swap on HumidiFi is approximately $0.40 — vs. $5–50 on Ethereum.

Slippage tolerance is the maximum price change you accept between submitting and executing your trade. The HumidiFi default is 0.5%, which works well for most liquid pairs like SOL/USDC. For less liquid assets, set slippage to 1–3%. For stablecoin swaps (USDC/USDT), you can set it as low as 0.1%.

Failed transactions on Solana cost near-zero (the small priority fee is burned). HumidiFi's transaction simulation engine pre-validates all swaps off-chain before submitting to prevent failures. If a swap still fails due to slippage exceeded, the transaction reverts and no funds move. HumidiFi automatically retries with adjusted parameters when appropriate.

HumidiFi distributes 40% of all protocol fee revenue as LP mining rewards on top of standard trading fees. Rewards are denominated in HMDF and accrue every epoch (12 hours). Additionally, select high-priority pools receive extra HMDF emissions voted on by governance. You can claim rewards anytime from the Rewards tab.

HumidiFi is a fully non-custodial protocol with no KYC requirements and no geographic restrictions at the smart contract level. The frontend at humidifi-dex.net may have geo-restrictions in certain jurisdictions in compliance with local laws. As a non-custodial protocol, users interact directly with Solana smart contracts and are responsible for compliance with their local regulations.
