Flashstack

Flash loan protocol on Bitcoin L2. Zero collateral. Built on @Stacks

BitGo has integrated the sBTC bridge.
Institutions can now convert BTC to sBTC and back directly within @BitGo.

Institutional-grade custody 🤝 Bitcoin-native finance.

[Gpsc.btc @GPSC_STX]

This is the real unlock.

@Stacks isn’t just adding yield on top of BTC — it’s creating the first native, Bitcoin-secured base rate.

$stBTC becomes the floor, and everything else builds on top of it.

This is a natural fit for Bitcoiners to dip their toes in to learn what real Bitcoin yield feels like.

Liquid staking is proven infrastructure on other chains. It never existed for Bitcoin because Bitcoin never had staking to build it on.

That's changing with stBTC from @StackingDao and @TychoOnnasch 🟩

First flash loan protocol on Bitcoin L2.

[Flashstack @FlashStackBTC]

Been building this quietly for months.
Today FlashStack goes public.

First flash loan protocol on Bitcoin L2 — borrow STX or real Bitcoin with zero collateral. Don't repay, the whole transaction reverses like it never happened.

@hillaryhardy12 Grateful to @StacksEndowment and @StacksOrg for backing this before it was proven.
If you're building on Bitcoin L2 — their grants program is real. Apply.

BIG news.

@UTXOmgmt, the Bitcoin native asset management arm of Nakamoto Inc., is the inaugural participant in Bitcoin Staking on Stacks.

This means institutional BTC earning BTC yield, without ever leaving the base layer.

[Dream @Airports57]

Stacks keeps expanding its Bitcoin economy.
• Bank of Punjab signed first national bank MOU in Stacks history
• Zest launched Bitcoin Collateral Vaults on Bitcoin L1
• 300K STX deposited into Zest lending market in single tx
Institutional adoption + BTCFi growth accelerating.

[Zest Protocol @ZestProtocol]

Zest Protocol is building the #1 use case for Bitcoin: lending and borrowing.

Hyperithm, who backed Zest Protocol early, sees the team with the track record to win.

[stacks.btc @Stacks]

You can't build the Bitcoin economy on infrastructure that doesn't scale.

Stacks core contributors explain the goal of 100x-ing throughput to support growth in user activity.

[Zest Protocol @ZestProtocol]

Zest Protocol is becoming the Bitcoin lending layer for institutions.

Backed by a two-year track record with thousands of liquidations and no bad debt.

[stacks.btc @Stacks]

Bitcoin Staking is the top of the funnel.

Stacks core contributors explain the flywheel beyond staking: Bitcoin-native finance, financial instruments, and a fully onchain Bitcoin economy built on Stacks.

[Stacks Endowment @StacksEndowment]

1/ The Bitcoin economy is being built right now. Builders are showing up. The @Stacks Ecosystem Grants program received a record 325 applications for Cycle 1.
