katana mainnet is live
katana mainnet is live, with 1 billion KAT available to users as incentives to bootstrap the chain
the wait is officially over: katana mainnet has launched, built to fix broken defi liquidity and yield. with over $240 million in pre-deposits in just a few weeks, katana goes live on mainnet with an ecosystem ready to use and users being rewarded from day one.
start using the beta version of katana app now to begin earning and take advantage of the 1b KAT liquidity mining incentives across core apps.
while the katana app is in beta, core assets available now to bridge include stablecoins (USDC, USDT, AUSD) and ETH. a native bridge UI path will be live in the coming days, supporting WBTC, WETH, and any other asset for clean bridge execution on all assets.
in the meantime, bridging large amounts of WBTC and WETH in and out the katana chain may incur bridge-related slippage—so, eyes sharp, samurai. but onchain, liquidity is deep. trade, borrow, vault, go crazy.
if you predeposited, now’s the time to have fun.
how to grow your bags with the katana app
the first version of the katana app simplifies your defi experience:
bridge, deposit, and earn into top yield opportunities in a single flow
easily add funds from more than 75 supported chains
explore 30+ apps on katana to earn, borrow, trade, and more
manage balances and defi positions
track earned KAT tokens in real-time, in a single unified view (from pre-deposits and the new KAT liquidity mining campaign)
view your full defi activity history and access comprehensive documentation
no guessing which apps are live. all are aggregated here and easy to navigate. come build on and around the core apps.
katana is for users. the app is only going to get better. alfa of what’s next:

for the thousands who participated in the predeposit campaign:
you’re og samurais. your assets are already earning in yearn v3 vaults on katana.
go check out your deposits on the katana app, and make sure you connect with the same wallet used for pre-deposits.
the underlying strategies in these vaults are earning vaultbridge-boosted yields plus KAT rewards. additional MORPHO and SUSHI token incentives come from core defi apps like morpho and sushi.
you've been patient, you're early, and now you're here.
welcome to katana.
mainnet puts your assets to work
katana mainnet brings the full potential of katana’s core economic mechanisms (the flywheel):
vaultbridge: enables yield from L1 strategies directly into katana defi pools
chain-owned liquidity (CoL): built over time with sequencer fees, reinvested into long-term ecosystem liquidity
AUSD (by agora): routes off-chain US treasury yield back to AUSD core app defi pools, diversifying and enhancing returns
net sequencer fees: every katana transaction generates fees. after paying for L1 data and infrastructure costs, net fees are routed back to core defi pools to boost yields and build deeper CoL.
together, these innovative mechanisms ensure katana’s defi yields and liquidity remain robust, attractive, and sustainable long-term.
pre-deposited assets: what you need to know
katana krates:
pre-deposit assets have been deployed to yearn v3 vaults.
your funds are already earning from multiple yield sources: native core app yield, vaultbridge-boosted yield, KAT incentives, and bonus MORPHO and/or SUSHI incentives.
no lock-up period; you can withdraw from vaults anytime, but it’s an opportunity cost: you’ll miss out sweet yield. by leaving your assets deposited, you’ll continue to earn yield on katana
over 67M unclaimed KAT from krate predeposits will be redistributed to participants, weighted by both deposit amount and length of deposit. more details coming soon
past depositors in turtle club + lombard + etherfi:
you’re still earning boosted KAT yield but must remain deposited for three months post-mainnet launch to earn full KAT APR (30 days for etherfi vault)
assets deployed to yearn v3 vaults on katana
early withdrawals result in reduced rewards (specific details via turtle club)
new depositors in turtle club:
you’re still early! to deposit in size to vaults and continue to earn, you can still deposit through turtle club
1b KAT liquidity mining campaign
a program planned for two years starts today, with KAT rewards heavily weighted towards the beginning of the campaign.
following the pre-deposit success, katana has allocated an additional 1 billion KAT tokens (10% of the supply) for post-launch liquidity incentives, consistent with the tokenomics laid out here:
sushi: 400M KAT (4.0%)
morpho: 250M KAT (2.5%)
future perpetual DEX, launchpad, & yield tokenization: up to 350M KAT (3.5%)
these tokens, immediately available as core app rewards, remain locked until KAT becomes transferable (no later than february 20, 2026 but expected earlier). track earned KAT in real-time through the katana app frontend.
so very smooth.
over time, with robust network effects, the mechanisms of the katana flywheel will replace KAT emissions as a cherry-on-top source of yield.
important note on KAT tokens
all KAT tokens earned during pre-deposit or liquidity mining phases remain initially non-transferable. KAT tokens become transferrable on, or sometime before, february 20, 2026. upon becoming transferrable, holders will be able to lock KAT to become vKAT holders. vKAT enables stakers to vote on which liquidity pools grow from future KAT emission. by voting for specific liquidity pools, vKAT voters earn fees from those pools. aligning incentives directly with ecosystem growth.
core apps and assets
katana launches with a select group of elite defi primitives, ensuring liquidity is concentrated, yields maximized, and fragmentation eliminated:
core apps:
sushi: spot trading with deep liquidity pools.
morpho: flexible lending & borrowing solutions.
perp DEX, launchpad, and yield tokenization: to come soon.
core asset providers:
agora (AUSD): native stablecoin capturing off-chain US Treasury yields.
bitvault (bvBTC): BTC-backed yield-bearing assets.
etherfi (weETH): liquid restaked ETH.
jito (jitoSOL): high-performance staked SOL.
lombard (LBTC and BTCK): liquid staked BTC & natively minted BTC.
universal (uTokens): cross-chain assets like uSOL, uXRP, and uSUI.
day one ecosystem & expanding defi universe
katana’s launch isn't limited to core apps and assets. it's a bustling defi ecosystem from the outset. day one sees a ton of protocols, live: spectra, charm fi, afi, steer finance, apebond, chimpx, demether, ichi, wolfswap, gamma, hikari, tea-fi, lucidly finance, stratifi, and yearn
that’s only to start. more launching soon, amping up to, more than 30 protocols in production, including: mizu, superlend, concrete, kaemon, kodachi, teller, tenor, treehouse finance, superform, levrex finance, summer finance, and more.
assets will grow in the coming days. core assets bvBTC, weETH, LBTC, BTCK, and uTokens will come to the chain late this week and early next week. many more assets to come. bring that jitoSOL over now, samurai.

infra for builders
katana launches day one with top-tier infrastructure providers ensuring a seamless and secure defi experiences:
chainlink: trusted data feeds, streams, and secure cross-chain interoperability (CCIP)
fireblocks: institutional-grade digital asset infrastructure
safe: secure multisig wallets and smart accounts
tenderly: reliable node RPC, dev environments, and exploration tools
thegraph: decentralized blockchain data indexing and querying
katana also integrates other critical infrastructure partners—including etherscan, rabby, zerion, li.fi, dune, fun.xyz/checkout, bitget wallet, debank, redstone, layerzero, merkl, zerodev, indexsupply, relay, blockscout, and defillama—to provide comprehensive, builder-friendly, and efficient defi tooling from day one.
long-term vision
as katana’s ecosystem expands, the flywheel intensifies.
liquidity deepens, yields rise, and the network reaches escape velocity. once KAT unlocks (on or before february 20, 2026), vKAT holders will directly influence future KAT emissions, driving sustained growth and ecosystem value.
the path ahead:
katana app: the app experience will continue to improve, making it easier to get on katana and start earning.
token unlock: february 2026, or sooner.
growth: katana evolves into a blooming, economically resilient chain, with apps for everyone and users having the best defi experience in the world for retail, whales and institutions alike.
