SolvBTC Lands on Tydro: Kraken-Aligned BTC Collateral on Ink L2

What started as a BTC reserve asset has evolved into a multi-venue BTC rail spanning 19+ networks, with SolvBTC now embedded across lending markets, liquidity pools, and yield strategies. SolvBTC has already proven collateral-grade demand on BNB Chain, becoming the largest Bitcoin asset on the network, widely utilized across ListaDAO and Venus lending markets, and even distributed via Binance Wallet’s loan flows, with ~90% utilization showing it’s BTC that’s actively being borrowed for DeFi composability.

Today marks the most meaningful step in that journey: SolvBTC is live on Tydro, Ink’s non-custodial money market, powered by Aave and incubated by Kraken.

With Kraken’s onchain ecosystem and Tyro recognizing SolvBTC as collateral-grade, SolvBTC is now eligible to anchor Tydro’s money markets and positioning it as a core Bitcoin collateral asset on Ink.

The Kraken Ecosystem Stamp

SolvBTC, asset listed on Tydro has passed through a risk framework with strict institutional standards behind it, collateral quality, liquidity depth, liquidation mechanics.

Here’s what makes this integration different from most DeFi lending integrations:

Ink is Kraken’s Layer 2, built to bridge the trust expectations of a compliance-strict CEX ecosystem with the composability of DeFi. Tydro is Ink’s flagship money market—powered by AAVE, with the risk layer (listings, parameters, and ongoing adjustments) managed directly by the Ink team.

That combination unlocks three things that matter most for serious BTC capital:

An institutional-grade credit lane powered by AAVE 

Non-custodial borrowing is standard DeFi. What’s rarer is borrowing inside a market where risk parameters are actively stewarded by Ink in a Kraken-aligned framework, making SolvBTC-backed borrowing more institutional-friendly through volatility.

Default-collateral network effects on Ink

Once SolvBTC sits inside Ink’s core money market, it becomes the easiest BTC building block for downstream protocols, vaults, LP strategies, perps, and structured products, accelerating integrations and reinforcing SolvBTC as a blue-chip BTC collateral asset in Kraken’s onchain stack.

SolvBTC Enters Kraken Ecosystem as a Blue-chip Bitcoin Asset

SolvBTC entered this environment alongside kBTC, Ink’s own native BTC wrapper and Its positioned one of the blue-chip BTC collateral assets in Kraken’s onchain stack.

kBTC launched as Ink’s native BTC asset. SolvBTC enters as the first external BTC wrapper to earn placement alongside it.

Assets that make it onto Kraken’s risk-managed money market have cleared a standard that most other wrappers don’t.

For the BTCFi ecosystem, the next phase of Bitcoin in DeFi will be determined by which assets pass risk committees, hold up in volatile markets, and become the default building blocks that other protocols reach for first.

SolvBTC’s arc started from BTC reserve primitive → multi-chain asset rail → Institutional-preferred asset → Kraken ecosystem collateral on Ink.

Unlock $INK Rewards Through Lending and Borrowing

SolvBTC is live on Tydro now and incentivized. 

The core mechanic is simple: active participation in the lending markets earns you $INK rewards.

• Supply SolvBTC to the lending pool → earn market-rate yield and accumulate $INK rewards proportional to your activity. 
• Borrow stables against your SolvBTC position → that borrowing activity also counts toward your $INK rewards.

Tydro rewards users who actually use the protocol, lenders and borrowers alike. The more you engage with the lending markets, the more proportional your share of $INK becomes. SolvBTC holders now have a direct path to earn those rewards.

Full details and market access are available through Tydro’s official app and documentation.

Bitcoin should work harder. 

SolvBTC on Tydro is how it does.
