On September 4, 2024, 21.co — the parent company of crypto ETP issuer 21Shares — officially launched 21.co Wrapped Bitcoin (21BTC) on the Ethereum blockchain, marking a significant step forward in the evolution of wrapped Bitcoin products. Developed in partnership with Flow Traders, one of the world largest proprietary trading firms, 21BTC promises institutional-grade security and seamless DeFi composability without the vulnerabilities that have plagued earlier wrapped token bridges.
TL;DR
- 21.co launched 21BTC, a new wrapped Bitcoin token on Ethereum, in partnership with Flow Traders
- Unlike traditional wrapped tokens, 21BTC uses cold storage custody instead of vulnerable lock-and-mint bridges
- The product leverages 21.co experience as one of the world largest crypto ETP issuers
- 21BTC enables Bitcoin holders to access Ethereum DeFi protocols without selling their BTC
- The launch coincided with Bitcoin trading near $57,971 amid broader market uncertainty
A New Approach to Wrapped Bitcoin
Wrapped Bitcoin tokens have been a cornerstone of cross-chain DeFi since the early days of decentralized finance. The concept is straightforward: lock Bitcoin on its native chain, then issue a corresponding token on Ethereum that can be used in smart contracts, lending protocols, and decentralized exchanges. The problem is that the bridge mechanisms connecting these two chains have historically been the weakest link in the security chain — literally billions of dollars have been lost to bridge exploits.
21.co aims to change that equation with 21BTC. Rather than relying on the traditional lock-and-mint approach that requires complex cross-chain bridges, 21BTC stores the underlying Bitcoin assets in institutional-grade cold storage with third-party custodians. No bridge means no bridge exploit — a design philosophy that reflects lessons learned from the numerous cross-chain hacks that have shaken the industry.
Institutional DNA and Regulatory Readiness
What sets 21BTC apart from existing wrapped Bitcoin solutions is the institutional pedigree of its issuer. As the parent company of 21Shares, 21.co operates one of the world largest crypto exchange-traded product platforms. The company brings the same stringent asset management practices and operational protocols that govern its regulated ETP products to the world of wrapped assets.
The partnership with Flow Traders adds another layer of credibility and liquidity infrastructure. Flow Traders, headquartered in Amsterdam, is a global liquidity provider that specializes in ETPs and other exchange-traded products. Their involvement ensures that 21BTC will have robust market-making support from day one, reducing slippage and improving the overall trading experience for users.
DeFi Integration and Use Cases
The primary value proposition of 21BTC lies in its ability to unlock Bitcoin liquidity for Ethereum-based decentralized applications. Bitcoin holders who have traditionally been limited to holding or trading on centralized exchanges can now put their assets to work across the Ethereum DeFi ecosystem. This includes lending protocols like Aave and Compound, decentralized exchanges like Uniswap, and yield farming strategies that were previously inaccessible to BTC holders.
The timing of the launch is notable. With Ethereum trading around $2,400 and the broader DeFi ecosystem showing signs of recovery after a challenging summer, the arrival of a new institutional-grade wrapped Bitcoin product could catalyze fresh capital flows into Ethereum-based protocols. The total value locked in DeFi had been recovering gradually, and products like 21BTC that lower the barrier to entry for Bitcoin holders could accelerate that trend.
The Competitive Landscape
21BTC enters a market currently dominated by WBTC (Wrapped Bitcoin), which has been the de facto standard for Bitcoin representation on Ethereum since 2019. However, WBTC has faced increasing scrutiny over its custodial model and the centralized nature of its operations. Other competitors include renBTC and tBTC, each with different approaches to the trust and custody question.
The 21.co product differentiates itself through its explicit institutional framework. By leveraging cold storage custody and avoiding bridge dependencies entirely, 21BTC addresses the two biggest concerns that institutional users have had about wrapped Bitcoin products: counterparty risk and technical vulnerability. The involvement of regulated custodians provides an additional layer of assurance that could attract a new class of institutional users who have been watching from the sidelines.
Market Impact and Future Outlook
The launch of 21BTC reflects a broader trend in the cryptocurrency industry toward institutional-grade infrastructure. As the market matures, products that combine the innovation of decentralized finance with the security standards of traditional finance are increasingly in demand. The Bitcoin ETF market, which saw outflows of $37.2 million on September 3 alone, demonstrates that institutional interest in Bitcoin exposure remains strong even during periods of market weakness.
For 21.co, the launch represents a natural extension of its core competency. The company already manages billions of dollars in crypto ETP assets across multiple jurisdictions. Bringing that expertise to the wrapped token market could accelerate the professionalization of cross-chain DeFi and set new standards for how digital assets are represented across different blockchain networks.
Why This Matters
Cross-chain interoperability remains one of the most important challenges in blockchain technology. Products like 21BTC that solve the security and trust problems of wrapped tokens are essential infrastructure for a multi-chain future. By bringing institutional custody standards to wrapped Bitcoin, 21.co is not just launching a product — it is raising the bar for the entire industry. As DeFi continues to mature and attract institutional capital, the demand for secure, professionally managed cross-chain bridges will only grow.

cold storage custody instead of a bridge is the right call. how many billions lost to bridge exploits now
bridge exploits account for something like 70% of all defi hacks. cold storage was the obvious move, surprised it took this long
21shares running the custody makes sense. they already manage billions in crypto etps. the infrastructure exists
flow traders as market maker is the real signal here. institutional liquidity from day one, not just retail hoping
competing with wbtc is bold. but wbtc has the first mover advantage and liquidity. 21btc needs defi integrations fast
wbtc liquidity is unbeatable for now but the custody model is a single point of failure. 21btc might win on trust if nothing else
no bridge means no bridge hack. such a simple concept yet it took this long for someone to do it properly
