The largest financing amount at the beginning of 2024 falls to the Bitcoin on-chain ecological track, but the protagonist may struggle to bear the weight
Author: DeMan
The prosperity of the Bitcoin public chain ecosystem may be the most mainstream narrative in the crypto space in 2024, with Bitcoin cross-chain transactions being one of the hottest tracks, accompanied by news of significant financing.
On January 30, it was reported that the decentralized exchange (DEX) Portal, based on Bitcoin, raised $34 million in a seed funding round, with participation from Coinbase Ventures, OKX Ventures, Arrington Capital, and Gate.io Ventures. This funding is intended for the development of Portal. Portal is a cross-chain atomic swap protocol that provides decentralized trading and wallet services. Portal plans to launch its product on the mainnet and expand its ecosystem to reduce custodial risks.
In fact, as early as September 2021, Portal completed a financing round of $8.5 million, with investors including Coinbase Ventures, OKEx Blockdream Ventures, and Tether co-founder Craic Sellars, among others, showcasing a strong lineup. Notably, its founding team has been strategically positioning itself in the Bitcoin on-chain ecosystem for a long time, demonstrating foresight, which is undoubtedly influenced by the unique experiences of its founders. Eric Martindale, co-founder and CEO of Portal, has been involved in Bitcoin for 10 years, serving as the open-source lead at Blockstream, engineering lead at BitPay, advisor at Lemniscap, and is also the inventor of Fabric.

The two rounds of financing have injected $42.5 million into Portal, but can Portal deliver the most efficient and secure Bitcoin on-chain DeFi applications as the industry hopes? The following text will provide a detailed introduction to this project for users.
Claiming High Security and Privacy, What Unique Features Does Portal's Atomic Swap Protocol Have?
Portal is a self-custodial Layer 2 wallet and cross-chain DEX built on Bitcoin to facilitate atomic swaps between Bitcoin and other crypto assets; built on Fabric technology, Portal offers privacy, high performance, and security. According to official information, Portal currently has four major business segments: Wallet, DEX, SDK (an interface to help developers build applications), and Rafa (an automated trading program).

The background of Portal's inception is likely very familiar to users. Since the launch of Ordinals, the trading volume of Bitcoin inscriptions has continuously reached new highs, giving rise to an on-chain trading ecosystem for Bitcoin, even directly competing with Ethereum to build a complete Bitcoin DeFi system. However, the question remains: how can assets on the Bitcoin chain be efficiently exchanged with those on the Ethereum chain? This has led to a new approach: "tokenized Bitcoin."
In simple terms, tokenized Bitcoin refers to wrapping Bitcoin into another format of asset from a technical and protocol perspective, allowing for a 1:1 value exchange on the Ethereum chain, with representative assets like WBTC (Wrapped BTC). However, this solution inevitably faces high costs in cross-chain transactions, privacy leaks, and poor liquidity. In response, Portal has created its own atomic swap protocol that alleviates these industry challenges to a large extent by aggregating liquidity, building order books, and transferring data to Layer 2, which likely explains the project's substantial financing.
Key Initiatives in Portal's Ecosystem Development, Understanding Its Potential Future Layout
In addition to progress in financing, Portal has also made impressive strides in ecosystem collaboration recently. The Ordinals NFT market and BRC-20 token exchange LFG have just announced the integration of the Portal DEX protocol into their cross-chain trading system, which will make cross-chain transactions between Bitcoin and other digital assets fast, secure, and private.
Historically, the exchange of NFTs and BRC-20 assets on the Bitcoin chain with mainstream assets has faced a series of issues, including cumbersome processes, back-and-forth switching, poor security, and the need for custodianship. As a new exchange in this emerging field, LFG cannot solve these difficulties through its own technical system; currently, LFG only supports BTC payments and transactions, which is also a consideration for user asset security. By introducing the cross-chain atomic swap functionality of Portal DEX, ETH, USDT, USDC, and even other Ethereum Layer 2 assets can be freely exchanged within LFG and the entire BTC ecosystem. In response, Portal has stated that it is actively integrating more public chains, wallets, and other DeFi projects on different chains.

So, why can Portal DEX provide such complex cross-chain trading functions? This is mainly due to the Fabric protocol.
Fabric itself is an open-source protocol built on Bitcoin to create an anti-censorship layer, which can be understood as a Layer 2 solution for Bitcoin, and Portal is built on Fabric. As a result, Portal inherits many advantages of Fabric, including censorship resistance, efficiency, trustworthiness, de-financialization, and cross-chain interoperability, while also inheriting the security of Bitcoin Layer 1. However, Portal's official statement indicates that the team has made a series of expansions on the functionality of Fabric, including extending its data computation capabilities, which may help in building gaming projects on the BTC chain in the future, although this is currently just a plan.
Additionally, while announcing the financing news, Portal also stated that it will launch an AI-driven investment application in the coming months to help users make intelligent investment decisions using AI technology. Currently, Portal has not disclosed much detail about this AI investment tool, but based on information from the official website, this tool is likely an upgrade based on the existing Rafa.

According to the official website, Rafa is an app that helps users achieve automated trading, and its official Twitter frequently recommends various new assets to users; however, the specific yield situation is currently unknown.
Risks Cannot Be Ignored: While 2024 Starts Well, Portal's Prospects May Not Be As Bright As Expected
In summary, Portal has achieved an ideal start in 2024, with over $40 million in financing far exceeding the industry average in a bear market, and its anchored Bitcoin on-chain ecosystem still presents multiple opportunities. However, the risks faced by Portal cannot be overlooked.
First, the enthusiasm for the inscription track has cooled, and the effects of a red ocean are beginning to show. At the same time, the Ethereum Cancun upgrade is approaching, and under the rotation of sectors, more hot money may shift from the Bitcoin ecosystem to the Ethereum ecosystem.
Second, the overall market situation is far from the conditions at the end of December last year; after the approval of the Bitcoin spot ETF, the industry has exhausted its positive news, leading to capital outflows, which will directly impact Portal's project operations in the future.
Finally, the most critical progress in Portal's ecosystem development is its deep binding with LFG, as mentioned earlier, but LFG itself is also a startup project, and its trading volume and user numbers are not ideal. This raises a deeper question: is the exchange of assets in the Bitcoin on-chain ecosystem for other public chains a pseudo-demand? Because the Bitcoin ecosystem has not yet produced applications of practical significance, many practitioners criticize its speculative nature. If the overall market cools down, the segmented market that Portal targets may have few excellent opportunities.
In conclusion, we believe that users participating in the Portal ecosystem and BRC-20 projects need to maintain sensitivity to overall market conditions and segmented tracks, and gaining a multi-dimensional understanding of the details within the ecosystem will aid in our decision-making.
