Katana (Ronin) exchange profile

Katana’s former swap page now directs users to Ronin Wallet Swap, while retaining a separate link to liquidity pools. The current service is therefore a continuing Ronin exchange with a changed swap entry point. An older tutorial showing the standalone swap screen should not be taken as the current navigation.[1]

DefiLlama’s Katana Ronin DEX entry displayed approximately US$10.98 million of TVL and US$20.9 million of trailing 30-day DEX volume at the 21 October 2026 research snapshot. The page aggregates Katana V2 and V3. Those figures describe deployed liquidity and turnover, not funded accounts or unique active customers. Its approximately US$14.50 billion cumulative volume is historical activity rather than available depth today.[23]

Each pool on the route charges its input token. Wallet Swap separately adds 0.5% in the output token. Network gas and price impact are additional considerations; percentages applied to different token bases cannot simply be added to determine the final cost.[3]

For a hypothetical 1,000-token input into a single 0.30% pool, the pool fee is 3 input tokens: 1,000 × 0.003. This isolates one fee only; it does not calculate output, price impact, gas or a subsequent pool’s charge.[7]

For a separate wallet-fee illustration, assume the route would produce 200 output tokens before the 0.5% wallet charge. That charge is 1 output token, leaving 199. This assumes the quoted amount already reflects pool execution; it excludes gas and rounding. Review the actual quote before submission.[3]

The wallet guide exposes maximum slippage, price impact, provider and transaction-fee details before confirmation. Review the minimum acceptable output in the chosen route. A tighter tolerance may cause failure; a looser one permits a worse execution price. Neither setting supplies missing liquidity or fixes an incorrect token selection.[4]

RON can arrive from an external exchange, an on-ramp or a cross-chain service. The funding guide stresses the destination network and notes that available fiat providers depend on country and currency. These are separate provider relationships, not a Katana bank deposit facility. Confirm that an external exchange currently supports withdrawals on Ronin before using its route.[10]

V2 fees compound within the pool position. V3 trading fees accumulate separately and require collection; they are not automatically reinvested. A single-sided V3 deposit can begin outside the active range and enter trading when price reaches it. That exposure needs monitoring even when the user is not submitting individual swaps.[5]

For cross-chain funding, inspect the source and destination network, provider, output, bridge-related route and fee breakdown. The wallet documentation describes one-click submission without a second wallet-signature prompt. Review those details before the final button; the page does not establish one universal arrival time or refund rule for every provider and route.[11]

Ronin Wallet is non-custodial: Sky Mavis cannot restore a lost seed or reset the relevant recovery secret for the user. That wallet control is distinct from assets committed to a Katana liquidity contract. A wallet displaying an LP token or NFT is showing a claim represented by that position, rather than keeping both original deposited token amounts idle in the wallet.[12][5]

Code4rena’s report, published in November 2024, covers the Katana V3 code reviewed during October 2024 and records no high- or medium-severity findings, alongside low/non-critical findings. Its examined scope includes contracts used for routing, migration and governance. This is evidence about that assessment, not certification of every later deployment, wallet release or bridge. Current live administrator and upgrade settings were not independently established.[24]

The current Ronin app displays a notice excluding citizens or residents of Vietnam. Its acknowledgement is an interface access condition. It should not be silently generalised into a rule about every unrelated wallet, token or exchange with Ronin support.[1]

Ronin Wallet terms require users to be at least 18 and of the age of majority where they reside, and apply legal and sanctions restrictions. They permit requests for further information and suspension of access. A successful wallet connection is therefore not proof of eligibility, and service access can be restricted without changing who holds the wallet’s private key.[25]

Katana labels Main and Seed tokens using published screening criteria; Seed covers newer or less established tokens, without a redemption guarantee. The creator guide requires review and whitelisting for a token creator’s own ERC-20 launch, distinguishes existing-token liquidity provision, and allows others to create pools after the whitelist period. Ordinary trading is a separate activity.[2][7]

The Ronin support portal provides a request route, product help and a linked service-status page. The portal was accessible during research; that is not a measured response time or a dealing guarantee. When reporting an execution issue, retain the public wallet address, network, transaction hash and relevant pool or position identifier, while keeping signing secrets private.[18]

No standard Katana customer tax certificate was established from the reviewed record tools. A useful record set includes token quantities and networks, pool fees, network charges, LP changes, reward receipts and the valuations used for the user’s own reporting. Public-chain history and a portfolio chart answer different accounting questions.[6]

The app-linked Sky Mavis terms describe a software interface and disclaim acting as a custodial wallet provider or exchange. They warn that digital assets may lack investor-compensation and deposit protection. No entity-specific exchange licence or named insurance entitlement for all Katana LPs was established. The Singapore company identity is not, on its own, a financial authorisation.[26]

The general app agreement specifies Singapore law and SIAC arbitration. Its arbitration opt-out uses [email protected] within 30 days of first use under that agreement. Ronin Wallet has a separate terms page with its own legal-notice address, [email protected]. The applicable agreement and its conditions matter; a support ticket is not automatically a valid legal opt-out.[26][25]

The privacy policy linked from the current Ronin app identifies Sky Mavis Pte. Ltd. as a Singapore-incorporated company. It is the named interface counterparty; the AMM pools, wallet software and blockchain have distinct technical functions. This profile concerns the Katana DEX on Ronin, not the separately branded Katana blockchain.[27]

Ronin’s 13 May 2026 announcement says its migration to an Ethereum L2 using the OP Stack was complete. RON remained the gas token and Katana LP positions were unaffected. It also announced a new explorer and the end of network staking rewards. Older directions to the legacy explorer or descriptions of validator-staking yield therefore require reconciliation with that change.[20]

The farm-creation guide requires a separately approved creator address and funded reward tokens. It defines rewards over a set duration, with a start at least seven days ahead, and permits changes under its published rules, including ending a published farm early and reclaiming unused rewards. Those conditions describe the mechanism; they do not establish a live reward rate for every Katana pool.[8]

The LP staking guide describes choosing an eligible farm, staking LP tokens and claiming its specified reward token. Current campaign eligibility and funding should be checked for that farm. This is separate from Ronin network staking, whose reward programme changed with the May 2026 network migration.[9][20]
