Everything you need to know about trading, staking, and earning on Kyo Finance on SONEIUM.
Kyo Finance is a decentralized exchange built on SONEIUM that combines automated market making with a vote-escrow governance model. Unlike simpler swap protocols, Kyo Finance ties liquidity incentives directly to veKYO token holders who vote on which pools receive emissions. This creates a flywheel: more locked tokens, more directed rewards, deeper liquidity in the pools that matter most.
The platform supports both standard volatile pairs and stable pairs with different AMM curves. Token tickers in play are KYO and veKYO. The protocol draws inspiration from the ve(3,3) model, but the Kyo Finance team has made significant modifications to the fee distribution and gauge weighting logic.
Connect your wallet using the button in the top-right corner of the Kyo Finance app. Once connected, select the token you want to sell in the top input and the token you want to receive in the bottom input. Enter your amount, review the quoted output and the price impact figure, then click the swap button.
If you enable Aggregator Mode, Kyo Finance routes your trade across multiple liquidity sources to find you a better rate. Slippage tolerance can be adjusted in the settings panel — the gear icon near the swap card. For most pairs a 0.5% slippage setting is fine; stablecoin pairs can usually go lower.
veSTAKING is the vote-escrow system at the heart of Kyo Finance. You lock KYO tokens for a chosen duration, receiving veKYO in return. The longer the lock, the more veKYO you get per KYO. veKYO is not a transferable token — it represents your time-weighted governance power.
Holders of veKYO vote each epoch to direct KYO emissions toward specific liquidity pools. In exchange for voting, they collect 100% of trading fees and bribes from the pools they voted for. It is a direct way to earn yield without providing liquidity yourself, though combining veKYO voting with LP positions is a common strategy among active participants.
You can access this feature via the veSTAKING tab in the main navigation.
The Kyo Finance team has engaged third-party security auditors to review the core contracts before the mainnet launch. Audit reports are referenced in the official documentation. That said, no audit eliminates all risk. Smart contract exploits remain possible on any protocol.
Best practices still apply: only deposit what you can afford to lose, check that you are on the correct URL before connecting your wallet, and keep large holdings in a hardware wallet. The Kyo Finance contracts are deployed on SONEIUM, so gas costs for precautionary exits are low relative to Ethereum mainnet.
Navigate to the POOL section. Choose between creating a new position or adding to an existing pool. You will need to supply both tokens in the pair at the current ratio. After depositing, you receive LP tokens representing your share of that pool.
Fee income comes from every swap that passes through your pool. The exact fee tier depends on the pool type — volatile or stable — set at the time of pool creation. On top of swap fees, LP token holders can stake those tokens in the corresponding gauge to earn KYO emissions, provided veKYO voters have directed emissions toward that gauge in the current epoch.
Standard AMM pools on Kyo Finance require both tokens in the pair. There is no single-sided deposit mechanism built into the core contracts at this time. If you only hold one token, you would need to first swap roughly half of it into the other token before depositing.
Keep in mind that splitting your position in one transaction versus two separate transactions can affect how much price impact you absorb. Using the built-in swap before adding liquidity is usually more efficient because Kyo Finance can route across its own pools.
The BRIDGE feature inside Kyo Finance lets you move assets from other networks into SONEIUM so you can use them on the platform. Supported source chains and bridge providers are shown directly in the interface — the list can change as the protocol adds integrations.
Bridging typically takes a few minutes depending on block confirmation times on the origin chain. Always double-check the destination address and that you have enough native gas on SONEIUM to interact with the protocol after your assets arrive. The Kyo Finance project page contains more background on the network strategy.
Price impact is high when the liquidity in a pool is thin relative to the size of your trade. A swap that moves the price by more than 1-2% will show a warning. You can reduce the impact by splitting your order into smaller chunks over time, or by enabling Aggregator Mode so the trade is routed across multiple pools.
A failed transaction most often means your slippage tolerance was too tight and the price moved before your transaction was confirmed. Raise slippage slightly, or try again during a period of lower volatility. Very occasionally a swap fails due to a gas estimation issue — refreshing the page and reconnecting your wallet resolves this.
The QUEST section hosts on-chain and off-chain tasks that reward participants for engaging with Kyo Finance. Tasks range from making your first swap to holding veKYO for a set number of epochs. Rewards are typically distributed in KYO tokens or protocol points depending on the active campaign.
Quest availability changes over time. Some quests have hard deadlines; others are ongoing. Completing quests is one of the ways newer users can accumulate KYO before committing to a longer veKYO lock, which makes it a sensible starting point for people who want to understand the protocol before putting significant capital in.
Aggregator Mode routes your swap across multiple liquidity sources rather than a single Kyo Finance pool. The toggle appears in the swap card toolbar. When enabled, the protocol queries external routes and compares them against its own internal pools, then executes through whichever path gives you the best net output after fees.
Turn it on for larger trades or for token pairs with low depth in Kyo Finance's own pools. For tiny trades on well-established pairs the gas overhead of multi-hop routing may actually net you less, so it is worth checking both options before confirming.
Each epoch, a fixed amount of KYO tokens is minted and allocated to gauges. The share each gauge receives is proportional to the veKYO votes it collected during the voting period. If a gauge received 10% of all veKYO votes, it gets 10% of that epoch's emissions.
LP stakers in a gauge then earn a share of that gauge's KYO allocation proportional to their staked LP token balance. The epoch length and total emission schedule are defined in the contracts. The emission rate is designed to decrease over time, so early participants receive relatively more KYO for the same LP position size than later entrants.
veKYO balance is calculated as KYO amount multiplied by the fraction of maximum lock time remaining. A two-year lock gives you far more voting power and fee-claim rights than a two-week lock for the same number of KYO. Short locks decay quickly, reducing your influence with each passing epoch.
Compounding matters here. A strong voting position lets you direct emissions toward pools where you are also an LP, which amplifies your yield on both fronts simultaneously. Participants with small balances often find that even a modest lock duration makes a meaningful difference in accumulated fees over a full quarter.
The PORTFOLIO tab gives a consolidated view of all your active positions: LP deposits, staked LP tokens in gauges, veKYO locks, and any unclaimed rewards. Figures update in near real time based on on-chain data.
You can also check your wallet balance for any listed token directly from the swap interface — the balance shows below each token selector. For detailed transaction history, SONEIUM's block explorer at soneium.blockscout.com lets you search by wallet address.
Once the lock period ends, your veKYO balance decays to zero. You can then withdraw the underlying KYO tokens freely. Your voting power and fee entitlements both drop to zero at expiry, so if you want to remain active in governance you need to extend or renew your lock before it runs out.
The UI will display a warning when your lock is approaching expiry. Extending a lock resets the decay counter from the new end date, not from today, so extending by a year on a lock that already expired gains you the same veKYO as locking fresh KYO for a year.
The Kyo Finance community Discord is the fastest way to reach the team and other users. A link to the Discord server is available in the support widget at the bottom-right of every page. There is also a Telegram channel monitored by moderators during most time zones.
For on-chain issues like stuck transactions, the block explorer is your primary diagnostic tool. For anything involving lost funds or suspected exploits, report directly in the Discord security channel so the team can investigate quickly.
