We’re excited to announce Swim’s launch on Karura, bringing a multi-chain liquidity pool to the Karura and broader Kusama ecosystem. Swim will provide Karura with USDT metapool liquidity for increased DeFi and stablecoin functionality. The integration allows our users to swap native stablecoins across eight supported ecosystems. Once Acala is live on Wormhole and aUSD is fungible across Karura and Acala, Swim will also add aUSD support for both platforms.

Meet Swim

Swim is a multi-chain AMM for native assets, designed to simplify bridging through multi-token liquidity pools and the Wormhole bridge. It eliminates the need for centralized bridges or wrapped assets by facilitating native token swapping across different chains. To leverage Swim’s product, users can simultaneously connect wallets from various protocols supported on Swim to facilitate native stablecoin swapping.

Swim’s AMM technology and Wormhole’s cross-chain communication make token swaps efficient across multi-chains. The model strengthens interoperability amongst different protocols with its barrier-eliminating solution for users performing cross-chain transactions.

Swim builds Web3 and blockchain’s market presence by:

Bridging the multi-chain blockchain ecosystem through Wormhole’s bridging technology
Employing an AMM-style bridge simplifying bridging tokens for native stableswap pools
Positioning itself as a core building block in the multi-chain ecosystem

Karura marks the eighth chain integration for Swim. BNB Chain, Avalanche, Ethereum, Aurora, Fantom, Polygon, Solana, and Karura form the growing list of supported chains enabling the native stablecoin swaps across their ecosystems.

Swim’s USDT metapool increases stable swap options for users

Karura and Swim’s integration enables the USDT metapool launch, meaning USDT on Karura is now a supported metapool on Swim. Metapools allow Swim to facilitate trading between new tokens and an existing metapool or Swim’s signature hexapool of USDC, USDT on Ethereum, Solana, and BUSD on BNB Chain.

Swim’s USDT metapool increases the swap pool, improving liquidity services for Wormhole. With Swim’s multi-token liquidity pools and an easy UX, Wormhole is evolving beyond bridging activities to offer increased DeFi functionality,

Using the USDT metapool provides a broader market pool for swapping stablecoins across an expansive network of protocols supported by Swim. Karura users can leverage the new integration to access efficient USDT liquidity and easy multi-chain stablecoin swapping.
