A Deep Dive into Bitlayer: Bitcoin DeFi Infrastructure
The Bitlayer Token Sale is live on CoinList until August 7 at 16:00 UTC.
Bitlayer is leading the next wave of Bitcoin DeFi with the first BitVM bridge, a Bitcoin-secured rollup, and a lightning-fast EVM-compatible layer. Backed by top investors and integrated with key partners, it’s delivering the full-stack infra Bitcoin has been waiting for.
We spoke with the team about combining Bitcoin-grade security with high-speed composability, the future of YBTC and BTR, and why 2025 is Bitcoin DeFi’s breakout year.

1. Bitlayer positions itself as the ultimate Bitcoin DeFi infrastructure. For those new to the project, what exactly is Bitlayer, and why is now the time to pay attention?
Bitlayer is emerging as the leading Bitcoin DeFi infrastructure solution at a pivotal moment - as Bitcoin's trillion-dollar liquidity attracts institutional players, the need for secure, scalable DeFi on Bitcoin has never been greater.
At its core, Bitlayer transforms the theoretical potential of BitVM into practical reality by combining Bitcoin's unmatched security with a high-performance execution layer. Bitlayer introduces two breakthrough innovations: a trust-minimized BitVM Bridge that converts BTC into yield-bearing YBTC for DeFi use, and a Bitcoin Rollup powered by BitVM stack and Real-time EVM that enables fast, low-cost smart contracts.
With its open ecosystem approach and growing partner network, Bitlayer is uniquely positioned to bridge Bitcoin's vast capital with the expanding world of decentralized finance, making now the ideal time for builders and users to engage with this next-generation infrastructure.
2. Bitcoin DeFi has long faced barriers due to Bitcoin’s limitations. How does Bitlayer unlock Bitcoin’s full potential while preserving its security model?
Bitcoin's limitations for DeFi are addressed through layered scaling, with on-chain verified Rollups becoming mainstream. Bitlayer adopts BitVM – a framework similar to Optimistic Rollups– to enable a trust-minimized BTC bridge and Bitcoin Rollup. Crucially, it preserves Bitcoin's native security while providing security-equivalent, Turing-complete smart contract capability without Bitcoin protocol changes.
By unlocking programmable DeFi capabilities directly on Bitcoin, BTC can now participate in sophisticated applications: yield generation, risk management, lending, and beyond, transforming Bitcoin from a store of value into a productive DeFi asset. This will be the foundation building block for the growth and expansion of Bitcoin DeFi.
3. Can you break down the BitVM Bridge? What makes it different from existing Bitcoin bridges and why is this such a pivotal innovation for trustless Bitcoin DeFi?
The BitVM Bridge represents a paradigm shift in trust models. Unlike previous generations of BTC bridge solutions— Gen 1 (custodial, requiring full trust) and Gen 2 (multi-signature, trusting majority signers)—BitVM requires trusting a minimum of one honest participant. This breakthrough is pivotal because it achieves trust-minimized and full programmability without requiring any changes to the Bitcoin base layer.
BitVM Bridge provides the first practical path towards onchain Bitcoin DeFi, from trust-minimized to trustless. It fundamentally redefines what's possible, enabling complex financial applications like lending and derivatives with security anchored directly to Bitcoin itself, finally unlocking its native DeFi potential.
4. With YBTC as a 1:1 BTC-backed asset, how does it function within the ecosystem and how does it enable real yield and liquidity across chains?
YBTC, a 1:1 BTC-backed asset secured by BitVM Bridge Network, brings programmable Bitcoin liquidity to mainstream blockchains. This full programmability unlocks DeFi's core requirement: composable utility.
Across multichain ecosystems, YBTC integrates natively with Bitcoin DeFi DApps—enabling lending, trading, arbitrage, and staking, etc. Crucially, this generates real yield opportunities: YBTC holders earn returns from protocol incentives by participating in these on-chain activities. By unlocking BTC's dormant capital across chains without custodial risk, YBTC positions Bitcoin as a productive token for decentralized finance.
5. Bitlayer has strong backers and ecosystem partners, from mining pools to infrastructure providers. What role do these partners play in scaling Bitlayer, and how do they contribute to long-term network resilience?
Bitlayer's partnerships are foundational to its scaling and resilience.
Strategic backing from top mining pools like Antpool, F2Pool, and SpiderPool – representing over 1/3 of Bitcoin's hashrate – is unprecedented. This cooperation not only builds up huge awareness for Bitlayer in the Bitcoin miner community, but also is the fundamentally strategic move for us to build high security, robust and good user experience BitVM Bridge solution for our Bitcoiner users. Bitlayer also is one of the 1st batch Bitcoin projects strategically working with ChainLink CCIP and LayerZero on the multichain interoperability, cross chain messaging side.
Integration with leading wallets (Binance Wallet, OKX Wallet, Trust Wallet, Bybit Wallet) is vital for adoption, ensuring smooth user access and growth. Together, these partners provide the security infrastructure, cross-chain capability, and user pathways needed for sustainable scaling and long-term network resilience.
6. What are some of the most exciting use cases and applications already being built on Bitlayer, or coming soon post-TGE? What kinds of builders should be paying attention?
Bitlayer is seeing explosive innovation across core DeFi pillars: high-utility protocols like Bitcoin lending, on-chain options trading, and perpetual DEXs are already live – addressing Bitcoiners' need for sophisticated financial primitives. We also have a few very innovative, frontier AI agent powered payment protocols that are coming to Bitlayer in the upcoming months.
We’re prioritizing builders who deeply understand Bitcoin-native user behavior, risk tolerance, and UX excellence. If you’re developing DeFi that respects Bitcoin’s security ethos while pushing composability boundaries, Bitlayer offers the ideal EVM-equivalent environment anchored to Bitcoin’s base layer.
7. How does Bitlayer’s architecture reflect Bitcoin’s ethos of decentralization and trust minimization while still embracing the flexibility of modern smart contract platforms?
Bitlayer Network embodies Bitcoin's core ethos by prioritizing decentralization and trust minimization through its BitVM-based Rollup architecture. Like Bitcoin, it relies on cryptographic proofs and on-chain verification – not trusted intermediaries.
Crucially, Bitlayer requires no changes to Bitcoin's base layer, preserving its robust security model. Yet, by implementing an EVM-equivalent environment atop Bitcoin via BitVM, it unlocks full programmability for DeFi and smart contracts.
This achieves a critical balance: inheriting Bitcoin’s battle-tested security and permissionless design, while delivering the flexibility modern applications demand – truly extending Bitcoin’s capabilities without compromising its foundational principles.
8. Looking at your 2025 roadmap, which upcoming milestones are most exciting for builders, contributors, and early supporters?
Looking ahead to 2025, two pivotal milestones will uniquely empower our ecosystem for builders, contributors, and early supporters. First, we’re accelerating the expansion of the BitVM Bridge ecosystem, driving deeper cross-chain interoperability and fueling the global adoption of YBTC—bringing Bitcoin-native assets to broader DeFi and institutional use cases. Next, the launch of Bitlayer Network Mainnet V2 will represent a major technical leap for Bitcoin Layer 2s. Together, these milestones reflect our commitment to advancing both the technology and the ecosystem, ensuring Bitlayer remains at the forefront of Bitcoin DeFi future.
