What’s happening on Stacks lately?

• Hermetica introduced hBTC, a Bitcoin yield product designed to earn from the top-performing DeFi strategies

• WalletConnect integration is underway, expanding access to Stacks apps for a much broader base of Bitcoin users

• Bitflow opened early access applications for HODLMM, its upcoming concentrated liquidity DEX

SIP-033 and SIP-034 (Clarity 4) has now been activated.

With new built-in functions and post-condition support, builders can create more powerful and efficient smart contracts.

Building on Bitcoin via Stacks has never been easier.

Dual Stacking gives Bitcoiners a clear incentive to put their BTC to work.

By simply holding sBTC on Stacks, they can earn a base yield.

But why stop there, when you can boost rewards up to 10x when you deploy sBTC in DeFi or stack STX alongside it.

An amazing milestone by the BD team on delivering the Circle integration.

As the liquidity layer for Bitcoin, Stacks can now welcome the world’s most trusted digital dollar into the ecosystem.

This makes Stacks the leading and only Bitcoin L2 with a tier-1 stablecoin.

The integration unlocks a dollar stablecoin issued on Stacks, fully backed onchain and 1:1 interchangeable with native USDC.

It means institutional and retail BTC can now tap into the world’s most adopted dollar liquidity, all managed by Circle.

Stacks is already the leading Bitcoin L2 by BTC supply.

Dual Stacking will keep pulling more BTC to Stacks, and the Circle collaboration for a USDC-backed stablecoin will cement that lead.

The setup for the Bitcoin economy to actually thrive is here.

The leading exchange MEXC is officially listing sBTC, a big milestone thanks to the BD team.

sBTC is now accessible to many more BTC holders worldwide, making it easier than ever to enter the Stacks ecosystem.

Another sign that Stacks is leading the Bitcoin economy growth.
