Almost none. RivrDEX runs on Vara Network, where the network fee is a tiny amount of VARA — a fraction of a cent, not an EVM-style gas bill. In practice you pay the 0.35% swap fee on each trade, and liquidity providers earn 0.3% of it. Your first swap is even better: a voucher covers its network fee entirely, so it works with a zero VARA balance.
Any fungible token deployed on Vara Network. If a trading pair already exists, you can swap immediately. If one doesn’t exist yet, you can create it yourself by depositing both tokens and setting the initial price. RivrDEX is fully permissionless — there is no token allowlist.
RivrDEX supports the following Vara-compatible wallets:
  • SubWallet (recommended)
  • Talisman
  • Nova Wallet
  • Polkadot.js extension
Install the extension for your preferred wallet, create or import an account, and connect it to the app at app.rivrdex.io.
No. RivrDEX is fully non-custodial. You retain control of your private keys and assets at all times. When you add liquidity, the tokens are held in on-chain pool contracts — but no central party can access or move your funds. Only you can withdraw your position by redeeming your LP tokens.
Impermanent loss occurs when the price of tokens in a pool changes relative to when you deposited them. Because the AMM rebalances your position to maintain the constant product formula, you may end up holding more of the token that fell in price and less of the one that rose.The difference between the value of your pool position and the value of simply holding both tokens outside the pool is called impermanent loss. It is “impermanent” because if prices return to their original ratio, the loss disappears entirely. Trading fees earned while you are in the pool partially offset this risk.
Impermanent loss is most significant in volatile or highly directional markets. Consider the risk before providing liquidity to pairs with large price swings.
Fees are not distributed immediately. Instead, they accumulate inside the pool over time, gradually increasing the value of each LP token. When you remove liquidity and burn your LP tokens, you receive your proportional share of the pool — your original principal plus all fees earned while you were in the pool.
Yes. RivrDEX is permissionless — anyone can create a new pair by depositing both tokens into a new pool contract. You set the initial price by choosing the ratio of tokens you deposit. Once created, the pair is immediately available for other users to trade and provide liquidity to.
Yes. All RivrDEX smart contracts are public and auditable. You can review the on-chain code directly on GitHub. Open-source development means anyone can verify how the protocol works and that there are no hidden mechanisms. See the Links page for the repository.
RivrDEX is deployed on Vara Network — a standalone layer-1 blockchain built on the Gear Protocol. Vara’s actor-based messaging model enables near-gasless transactions and high-throughput on-chain execution, making it well-suited for a real-time DEX.
RivrDEX is live on Vara Network mainnet. You trade with real assets — VARA and tokens bridged from Ethereum. Follow rivrdex.io, X, and Discord for announcements and new features.
Two ways: buy VARA on an exchange — Coinbase, Gate.io, or Crypto.com — and withdraw it on the native Vara Network, or bridge USDT from Ethereum with the Vara Network Bridge (~20 minutes with Fast speed). The bridge also carries ETH, BTC, and USDC, but the DEX currently trades only against wUSDT — bridge USDT unless you specifically need another asset on Vara. See Get tokens for the step-by-step walkthrough, and vara.network/get-vara for the current exchange list.
No. Your first swap is covered by a voucher — RivrDEX pays the network fee for it, even if your VARA balance is zero. Typical flow: bridge USDT → wUSDT, then make your first swap wUSDT → VARA. After that you hold VARA, which covers gas for all future transactions.
Your balance is most likely sitting as wVARA (wrapped VARA). Check the Swap page — if you hold wVARA, a “You have … wVARA” banner appears at the top; click Receive VARA to convert it on the spot. You can also convert from the bridge’s My Tokens tab. Also refresh the page or reconnect your wallet: balances sometimes display stale numbers. In every reported case so far, the funds were safe on-chain.
A loyalty program where trading earns you points. Points build XP and levels, unlock loyalty multipliers up to +25%, and can be spent in the rewards shop on USDT coupons, hardware wallets, and an exclusive Discord role. Your wallet is the account — join at rivrdex.io/rewards. See the Rewards overview for details.
No. Points are campaign points tracked by the rewards program — they are not a cryptocurrency, are not transferable, and exist only to be redeemed in the rewards shop. Points you spend are deducted from your balance, but your lifetime XP and level never go down.
The usual reasons, in order of likelihood:
  • Your wallet wasn’t verified yet — only swaps made after you verify at rivrdex.io/rewards count.
  • The day hasn’t closed — trading points are credited shortly after 00:00 UTC. Until then they show in the live “Earning today” counter.
  • You hit the daily cap — trading points max out at 150 per day (before your loyalty multiplier).
See Earning points for the full rules.
