Weekly Ecosystem recap May [12-18]
Let’s break down the week.
1️⃣
@Starknet makes Bitcoin private
strkBTC is now live on Starknet.
The important part is not just another wrapped BTC asset. It is the privacy layer around it. Users can bridge BTC through
@gardenfi or
@atomiqlabs, receive strkBTC and shield it directly inside the wallet.
No separate privacy app. No weird extra flow. Just BTC liquidity with optional shielding and public DeFi access when needed.
That is a serious unlock for institutions that cannot put every position, counterparty, and movement on a public timeline.
2️⃣
@endurfi turns strkBTC into yield
@endurfi shipped xstrkBTC alongside the strkBTC launch.
The flow is simple: native BTC -> strkBTC -> Endur stake -> xstrkBTC -> Starknet DeFi.
The cleaner part is UX. Endur also refreshed the app with bridge stake mint in one surface. That matters more than people think. BTCFi does not scale if every deposit requires three tabs, five signatures, and users guessing where funds landed.
3️⃣
@Stacks pushes BTC-denominated yield
@Stacks published the Bitcoin Staking whitepaper.
The pitch is direct: hold BTC, earn BTC, keep custody, and source yield from Stacks miner revenue instead of random reward tokens.
This is the right direction for Bitcoin users. They do not want synthetic yield theater. They want to know where the yield comes from, what risk they are taking, and whether they are still holding Bitcoin.
4️⃣
@ZestProtocol enters token mode
@ZestProtocol confirmed
$ZEST, opened the eligibility checker, and set trading for
@binance Alpha on May 19.
They are also launching the
$ZEST-STX pool on
@bitflow.
This is the standard liquidity formation phase: token distribution, claim checks, exchange access, DEX liquidity, and narrative control around Bitcoin lending. The bigger signal is that Stacks DeFi is becoming more financialized, not just more active.
5️⃣
@build_on_bob expands the Gateway
@build_on_bob integrated BOB Gateway into
@RouterProtocol.
Native BTC routes are now available for Router users and partner apps across 11 chains, with BOB-supported BTC route frontend fees waived for three months.
They also pushed native BTC ↔ tokenized gold swaps through BOB Gateway. That is a very specific direction: Bitcoin as the entry asset, routing as the product, and non-custodial swaps as the UX wedge.
6️⃣
@Lombard_Finance hardens cross-chain BTC
@Lombard_Finance is replacing LayerZero with
@chainlink CCIP across Solana, Etherlink, Berachain, Corn, and TAC for LBTC and BTC.b infrastructure.
LayerZero on Morph and Swell is being deprecated.
This is not a small backend change. Cross-chain BTC assets live or die by security assumptions. If BTC is going to move across ecosystems at serious size, bridge infrastructure cannot be treated like a growth hack.
7️⃣
@rootstock_io keeps leaning into security
@rootstock_io highlighted several important updates this week.
The network surpassed 20M transactions, pushed the “secured by Bitcoin hashpower” message again, and covered
@DMND_Sv2 bringing Stratum V2 mining pool architecture with direct rBTC rewards from merge mining.
They also warned users that the Ethereum ↔ Rootstock Token Bridge is sunsetting, with
@StargateFinance recommended going forward.
Not flashy, but important. Old routes get deprecated. Mining infrastructure improves. UX paths change. That is what mature chains have to do.
8️⃣
@babylonlabs_io publishes the risk framework
@babylonlabs_io released SCRIPT, a Bitcoin Collateral Risk Assessment Framework.
This is the kind of content BTCFi needs more of.
Everyone wants to call their product trustless, native, secure, or institutional-grade. The harder part is giving users and applications a way to compare counterparty risk, custody assumptions, collateral design, and failure modes across different BTC collateral systems.
BTCFi is no longer just “put BTC somewhere and earn points.”
See you next week 🫡
