Tuna Chain Integrates Portal DeFi to Enable Cross-Chain Swaps All In-App

Tuna Chain, the first modular Layer 2 solution on Bitcoin, today announced a new integration with Portal DeFi, the world’s first trust-minimized Layer 2 cross-chain swaps protocol that involves no bridges, custody or wrapping. The partnership will integrate $Tuna token in the Portal DEX network, making it one-click cross-chain tradable with native BTC, BRCs and native assets on top Layer 1 and Layer 2 chains.

“We are thrilled to partner with Portal DeFi, marking a significant leap in blockchain interoperability and user empowerment. This collaboration not only integrates $TUNA within the expansive Portal DEX network but also enhances the liquidity and accessibility of our native assets across multiple chains without compromising security," said Ax, COO of Tuna Chain. "By aligning with Portal’s innovative cross-chain technology, we are setting a new standard for seamless and trust-minimised trading within the cryptocurrency ecosystem, furthering our mission to bridge the gap between decentralised and centralised financial services.

As the first DEX of its kind, Portal facilitates trust-minimized, cross-chain swaps that involve no bridges, custody or wrapping. This integration of the Portal Swaps SDK into the Tuna Chain infrastructure, allows users to buy and sell native BTC, Eth and other cross-chain cross-layer assets without leaving the Tuna ecosystem. Further, Portal DEX will integrate Tuna’s revolutionary stablecoin $Toro, making it one-click cross-chain tradable against assets on other chains and support pools of $Tuna token in Portal’s cross-chain DEX. This integration will allow the Tuna community to benefit from the users and liquidity of the broader Portal DEX Network (wallets, DEXs, bridges using Portal Swaps SDK) enabling users to buy and sell both native and bridged assets directly inside ecosystem applications.

“We are excited to offer Tuna Chain users the ability to buy and sell directly in-app to benefit from the speed and seamless user experience ordinarily associated with centralised exchanges, trustlessly,” said Chandra Duggirala, CEO and co-founder of Portal. “Our partnership represents our shared vision with Tuna Chain of increasing financial access for the masses and signifies an important step towards this.”
