Executive Summary: Decentralized Front-Ends for DeFi Protocols

1. Technical Implementation of Decentralized Front-Ends

Decentralized Hosting Methods:

DeFi front-ends (the web interfaces users interact with) can be hosted on distributed, censorship-resistant storage networks instead of centralized servers. Common approaches include IPFS (InterPlanetary File System), Arweave, Sia/Skynet, and others:

• IPFS: IPFS is a peer-to-peer content-addressable storage network.
• Filecoin (IPFS+Incentives): Filecoin is a sister network to IPFS that adds economic incentives for storage.
• Arweave: Arweave is a decentralized permanent storage network (the “Permaweb”).
• Sia/Skynet: Sia is another decentralized storage network where users form smart contracts with hosts to store data (hosts put up collateral and are penalized if they fail to store the data)
• Other Distributed Hosting: Besides the above, there are other niche solutions.

DNS Alternatives & Accessibility:

Replacing the hosting is one part; the other is how users find the front-end. Traditional DNS (e.g. app.uniswap.org) is centralized – domains can be seized or censored by authorities or registrars. To avoid this, DeFi projects use decentralized naming systems like ENS or Handshake, and other censorship-resistant links:

• Ethereum Name Service (ENS): ENS provides human-readable .eth names that are owned via Ethereum smart contracts.
• Handshake: Handshake is a decentralized DNS root protocol.
• Direct IPFS links and Others: Some users can bypass naming entirely by using the content hash URL.

Censorship Resistance vs. Usability:

A key challenge is ensuring accessibility without central dependencies. Decentralized front-ends can be made available through multiple channels – ENS domains, Handshake domains, IPFS gateways, etc., so that if one route is cut off, others work. For example, the Chainlink team’s “unstoppable web” demo stored their site on several networks (Arweave, Sia, Filecoin/IPFS) and then used an ENS name to map to all those content hashes as backups (Decentralized Storage (dStorage): A Beginner’s Guide | Chainlink) (Decentralized Storage (dStorage): A Beginner’s Guide | Chainlink). If the primary gateway was down, users could retrieve the hashes from ENS and plug them into another gateway or directly into their IPFS/Arweave node (Decentralized Storage (dStorage): A Beginner’s Guide | Chainlink). This multi-layer approach (multiple storage networks + a decentralized name + multiple access points like Tor or gateways) maximizes censorship-resistance. On the flip side, each added layer can hurt convenience (casual users may not know how to switch gateways or configure a browser). Many DAOs therefore maintain hybrid setups: a user-friendly web2 route that quietly serves from a decentralized backend. Uniswap did this by pointing app.uniswap.org (a DNS domain) to Cloudflare’s IPFS gateway via DNSLink (Uniswap Interface + IPFS). Users going to the normal URL were actually getting the IPFS-hosted app behind the scenes (Uniswap Interface + IPFS). This kind of approach uses central infrastructure (Cloudflare DNS and gateway) as a performance and accessibility booster, but if that fails, the truly decentralized routes (like dweb.link or uniswap.eth) are still available. In summary, DNS alternatives like ENS/Handshake are crucial for decentralization, but projects often combine them with traditional DNS or gateways for convenience. The goal is to make the decentralized front-end feel as smooth as a normal website while retaining the ability to fall back to censorship-resistant access if needed.

Security Considerations in a Decentralized Front-End Model:

Moving the front-end to decentralized hosting changes the threat model. There’s no centralized server to hack, but new risks emerge around the integrity of the content and the controls for updating it:
