₿ BTC Karma Adds Phantom Wallet Support, Easing Bitcoin's Path Into Cardano DeFi

 CSWAP announced that BTC Karma — one of the first Bitcoin-native DeFi protocols running directly on the Cardano mainnet — now supports the Phantom wallet. Bitcoin holders can connect Phantom and stake BTC in just a few clicks, earning yield while participating in the Cardano ecosystem.

CSWAP framed the integration as a liquidity gateway: each additional wallet supported lowers the friction for Bitcoin liquidity to enter Cardano-based applications. CEO Jon Kravetz said more wallet integrations are already in development, with further onboarding paths on the way.

The move fits Cardano's broader 2026 push to bring idle Bitcoin capital on-chain to earn yield. Turning BTC into productive collateral on #Cardano widens the potential user and liquidity base for DeFi on $ADA, tapping one of the largest pools of dormant capital in crypto.

🛠️ TxPipe Adds Leios Support to Pallas

TxPipe announced new Leios support in Pallas, its Rust library for Cardano. Developers can now talk to the Ouroboros Leios protocol directly from Rust, and the update is ready to run against the live Musashi Dojo Leios public testnet.

This gives builders early, low-level access to Cardano's next-generation scaling layer as it moves through public testing toward a mainnet hard fork targeted later in 2026. It is a concrete new protocol capability, letting infrastructure teams, indexers, and tooling providers build against Leios now rather than waiting for mainnet.

TxPipe's pattern of shipping open-source #Cardano infrastructure — alongside Dolos, Oura, and Tx3 — keeps lowering the barrier for developers and AI coding agents to build on $ADA. Leaner, ready-to-use tooling is exactly what turns scaling research into products real users can touch.

🏛️ Cardano Foundation's June Update Highlights New Partnerships and Governance Progress

Cardano Foundation published a transparency report showcasing new partnerships and strong governance progress across the ecosystem, reinforcing its expanding role as steward of community funding and constitutional processes.

The report includes the publication of the Foundation's voting rationale for all 69 proposals in the 2026 Intersect budget process, alongside ongoing Governance Hours, a Community Director process, and Constitutional Committee elections run through Intersect — turning institutional voting from a black box into a reviewable public record for the community.

By consistently documenting its decisions and partnerships in monthly reports, the Foundation reinforces a pattern of accountable, transparent stewardship at a moment when Voltaire-era governance is being tested with real treasury decisions on #Cardano. This kind of routine transparency is exactly what a maturing on-chain governance system needs to build long-term trust in $ADA.
