The decentralized finance ecosystem on Ethereum is about to receive its most significant infusion of bitcoin liquidity yet. Thesis, the crypto venture studio behind the Keep network, has closed a $7.7 million funding round as it prepares to launch tBTC — a bitcoin-pegged token designed to bring the world’s largest cryptocurrency into Ethereum’s rapidly growing DeFi ecosystem.
Announced on April 2, 2020, the funding round comes at a critical juncture for both bitcoin and decentralized finance. While bitcoin has been recovering from its mid-March crash to trade around $7,271, the broader DeFi ecosystem on Ethereum has been steadily building infrastructure that could fundamentally change how value moves across blockchain networks. Ethereum itself was showing strength, trading at approximately $169 — up over 17% on the day and a remarkable 27% over the past week.
TL;DR
- Thesis closes $7.7 million funding round ahead of tBTC launch on April 27
- tBTC will allow bitcoin holders to use BTC in Ethereum DeFi applications without centralized intermediaries
- Keep network provides the trustless infrastructure for the Bitcoin-Ethereum bridge
- Ethereum surging 17% daily as DeFi momentum builds
- Ether-Bitcoin volatility spread hits 4-month low, signaling converging market dynamics
What Is tBTC and Why Does It Matter?
tBTC is an open-source project that allows bitcoin holders to deposit BTC and receive a corresponding ERC-20 token on the Ethereum blockchain. Unlike wrapped bitcoin solutions that rely on centralized custodians, tBTC uses a decentralized system of signers operating on the Keep network to manage the peg. The result is a trustless bridge between the two largest blockchain ecosystems — one that preserves the security guarantees that make bitcoin valuable while unlocking access to Ethereum’s programmable financial infrastructure.
Matt Luongo, CEO of Thesis — which is also the parent company of Fold and Keep — has positioned tBTC as the key to unlocking billions of dollars in dormant bitcoin liquidity. For years, bitcoin holders have watched from the sidelines as Ethereum’s DeFi ecosystem exploded with lending protocols, decentralized exchanges, and yield-generating applications. tBTC aims to give those holders a way to participate without surrendering custody of their assets to a centralized third party.
The Keep Network: Decentralized Infrastructure
The technical backbone of tBTC is the Keep network, a privacy-focused layer that enables secure off-chain computation. In the context of tBTC, Keep provides the infrastructure for a group of signers who collectively manage the bitcoin deposits backing each tBTC token. These signers must post collateral in the form of KEEP tokens, creating a strong economic incentive for honest behavior.
This design addresses one of the most persistent criticisms of existing bitcoin-on-Ethereum solutions: the single point of failure created by centralized custodians. By distributing trust across multiple signers with real financial stakes in the system’s integrity, tBTC offers a more resilient and censorship-resistant approach to cross-chain asset transfers.
DeFi Ecosystem Primed for Bitcoin Liquidity
The timing of tBTC’s arrival is noteworthy. The DeFi ecosystem on Ethereum has been growing at a rapid pace, with protocols like MakerDAO, Compound, and Uniswap establishing themselves as foundational building blocks for decentralized financial services. However, the total value locked in DeFi has been constrained by the fact that the cryptocurrency market’s largest asset — bitcoin, with its $133 billion market capitalization at the time — has been largely absent from the ecosystem.
The ether-bitcoin price volatility spread hit a 4-month low around April 6, 2020, according to CoinDesk data, suggesting that the two largest cryptocurrencies were moving in increasingly correlated patterns. This convergence could make cross-chain solutions like tBTC more practically useful, as reduced volatility between the two assets minimizes the risk of peg instability.
The broader market context adds urgency to the project. The COVID-19 pandemic has triggered unprecedented monetary stimulus from central banks worldwide, with the U.S. Federal Reserve announcing essentially unlimited quantitative easing. The resulting concerns about currency debasement have renewed interest in bitcoin as a store of value — and by extension, in solutions that can make bitcoin productive within decentralized financial applications.
Why This Matters
The launch of tBTC represents more than just another token on Ethereum. It is a test of whether the two dominant blockchain ecosystems can be bridged in a truly trustless manner. If successful, tBTC could unlock a wave of bitcoin liquidity into DeFi, potentially doubling or tripling the total value locked in decentralized financial protocols. The $7.7 million raised by Thesis signals that investors are betting on this outcome — and that the crypto industry is increasingly focused on interoperability rather than tribalism. As the April 27 launch date approaches, all eyes will be on whether tBTC can deliver on its promise of decentralized, censorship-resistant Bitcoin-Ethereum connectivity.

tbtc was supposed to be the trustless bridge that changed everything. then the first version had bugs and wbtc won by just being simpler
$7.7 million for a Bitcoin-Ethereum bridge in April 2020 was ambitious. The real question is why it took so long for wrapped assets to become standard infrastructure.
Henrik J. 7.7M was cheap for building the first trustless BTC bridge. problem was every successor had a critical bug within weeks of launch
tbtc v2 is actually live and working now. took 3 years longer than anyone expected but the trustless model finally shipped
3 years late but the trustless model is finally production grade. wbtc still has more tvl but the centralized counterparty risk is starting to matter
wbtc won because bitgo was already trusted. trustless bridges sound great until you see the exploit history
wrap_skep WBTC won on liquidity not trust. BitGo had first mover advantage and DeFi composability locked it in before anyone could challenge the centralized model
bridge_orphan_ WBTC won on liquidity not trust is exactly right. first mover advantage in DeFi composability is nearly impossible to overcome
wrap_skep WBTC won because BitGo was trusted AND because it launched first. tBTC had the right idea 3 years too late
eth up 17% in a single day to 169 and the keep network thesis made so much sense on paper. bringing btc liquidity to defi was the right call, execution just couldnt keep up
17% eth pump in one day was the defi signal. everyone suddenly wanted yield and btc holders needed a bridge. timing was perfect, execution was not
tBTC was supposed to kill wBTC and instead both just coexist now. the bridge thesis was right but the timeline was brutal, 2020 to actual adoption took half a decade
ETH at $169 up 17% in a day. April 2020 was the DeFi genesis moment. nobody knew it then but compound, aave, and uniswap were about to change everything
$7.7M to build a trustless BTC bridge in 2020 was ambitious. everyone else just did wrapped IOUs and called it a day
tbic_skep_ tBTC launch was supposed to be April 27 2020. it got delayed multiple times. the Keep network signers were buggy
tBTC was supposed to be the trustless bridge and then it launched with a federation of signers anyway. the gap between the whitepaper promises and v1 reality was brutal
tbic_ghost_ the gap between the whitepaper and v1 reality was brutal. promised trustless, delivered a federation of signers. took 3 more years to fix what should have been day one
ETH at $169 up 17% was when DeFi went from side project to main event. the Keep Network thesis was correct, the execution was 3 years late
BTC at $7,271 and ETH at $169 when this dropped. wild to think that was the entry point for a bridge nobody asked for yet
ETH at 169 up 17% in a day. April 2020 was when DeFi went from hobby to industry and nobody realized it yet
bought KEEP at the tBTC hype peak. token bled for 2 years straight. the tech worked eventually but the tokenomics were non-existent. classic 2020 DeFi experience
keep bagholders always the same story. the tech eventually works but the token bleeds for years. KEEP was supposed to be 5 dollars, bought at 0.60 and watched it go to 0.02
7.7M raise for a BTC bridge in 2020 was honestly nothing. most defi protocols were raising 2-3x that and still died. thesis played the long game
7.7M for the keep network thesis was cheap. the problem was every trustless bridge that launched after had a critical bug within weeks
