Sundae V4 Don Launch for Cardano With Two RealFi Pools
The initial rollout opens a USDCx/USDrf Linear Swap pool and a USDrf/sUSDrf stableswap pool. Atomic routing connects both markets, while additional V4 features will roll out in stages.

Sundae Labs don launch Sundae V4 for Cardano mainnet on October 1, 2026, open two pools together with RealFi mainnet debut. The deployment connect USDCx liquidity with the new RealFi stablecoin and im staked counterpart.
SundaeSwap na decentralized exchange for Cardano wey dey enable token swaps and liquidity provision through smart contracts. V4 introduce configurable pool structures and new order execution system.
Two RealFi Pools Start the V4 Rollout
Pi Lanningham, CTO of Sundae Labs, explain say two V4 pools dey live at launch: USDCx/USDrf Linear Swap and USDrf/sUSDrf stableswap. Sundae Labs describe the release as gradual rollout to support testing and im RealFi partnership.
RealFi dey issue $USDrf, one stablecoin wey dem design to track the U.S. dollar with backing from real world financial assets. Im staked counterpart, $sUSDrf, represent share of the protocol staking vault.
RealFi dey calculate sUSDrf redemption value by dividing the value wey dey back im staking vault by the number of sUSDrf tokens wey dey circulate. As portfolio income dey allocate, the amount of USDrf wey each sUSDrf represent fit increase.
This difference na wetin shape the two opening markets. USDCx/USDrf dey connect dollar assets with fixed exchange ratio. USDrf/sUSDrf dey trade between the base stablecoin and token wey get changing redemption value.
According to Sundae Labs, the stableswap reference ratio dey follow that value as returns dey accrue. Movement for the reference ratio dey different from trading slippage, wey happen when order push the pool away from im reference price.
Linear Swaps and Routing in One Transaction
The Linear Swap pool dey exchange USDCx and USDrf at 1:1 ratio with predictable percentage fee. According to the team, even if order size increase, e no go move the exchange rate within available reserves.
Conventional constant product pool dey change im quoted price as trades dey alter the balance between im assets. Linear Swap keep the exchange ratio fixed. Sundae design this model for stablecoin conversions for payment flows and other applications wey require predictable amounts.
Im capacity depend on inventory. If demand drain one token from the pool, orders wey require that asset no fit get fill for there again until reserves don replenish. The available balance dey limit execution without the exchange rate dey progressively worsen.
Lanningham talk say atomic routing dey connect the two opening pools inside single Cardano transaction. USDCx to sUSDrf swap go pass through the Linear Swap pool to obtain USDrf, then pass through the stableswap pool to obtain sUSDrf. The reverse route go follow the same markets for the opposite direction.
The user go submit one routed order, with the two exchange steps settling together. This process dey purchase existing sUSDrf from pool liquidity. To deposit USDrf into RealFi staking vault and receive newly issued sUSDrf remain separate protocol operation.
Modular Pools and Further V4 Deployment
V4 modular architecture dey separate pool reserves and liquidity provider claims from configurable components like pricing curves, execution rules, and permissions.
The design allow specialized markets to share Sundae interface and routing infrastructure. Builders fit adapt pool behavior to one asset or product while dem still connect to the exchange existing order flow.
V4 broader routing model allow orders to specify the desired asset and minimum output while execution dey search available paths. Sundae talk say any additional output wey improved routing produce go go to the user.
The wider design include concentrated liquidity, custom vaults, limit orders, and partial fills. Their mainnet availability no confirm inside the initial launch announcements.
Access to the underlying tokens still dey subject to RealFi eligibility rules. Their documentation exclude users for the United States, European Union, European Economic Area, United Kingdom, Hong Kong, and other restricted jurisdictions.
RealFi mainnet launch now get dedicated markets for both im base stablecoin and staked token for Sundae V4.
