The Opportunity: Uniting Fragmented DeFi Liquidity

Decentralized Finance (DeFi) has introduced a new financial landscape where users enjoy transparency, security, and complete control over their assets. However, despite these advantages, DeFi still trails behind centralized exchanges (CeXs) in terms of user adoption. 

Outside of the subpar UX offered by tools such as MetaMask, the primary challenge is fragmented liquidity. In DeFi, liquidity is scattered across different blockchains and platforms, often making token liquidity network-specific or even DEX-specific. As a result, users are forced to manage multiple wallets, frequently bridge assets across chains, and distribute funds across networks. This creates a complex, inefficient, and often frustrating trading experience.

Even after high-profile CeFi failures like FTX, where significant amounts of user funds were lost, centralized exchanges continue to dominate. Despite the risks of CeFi - such as poor oversight, security vulnerabilities, and the risks of leaking personal data - users prefer the convenience it offers. On centralized platforms, trading is seamless, and liquidity is readily available, unlike in DeFi, where users must navigate fragmented ecosystems to access liquidity.

This gap presents a massive opportunity for DeFi. While crypto CeFi serves approximately 420 million users globally, DeFi has only captured about 5 million of those users. Crypto exchanges handle over $84 billion daily spot trading and another $102 billion in derivatives. While DeFi promises greater security and control, it hasn’t yet managed to capture anywhere near the share of this activity that it should have. What’s needed is a solution that brings liquidity together in one place, providing access to all crypto assets in a seamless, user-friendly way while maintaining DeFi’s core values of decentralization and user control.

Flash Liquidity: The Solution to Fragmented Liquidity

Flash Liquidity, a groundbreaking system being developed on Radix, directly addresses DeFi’s liquidity fragmentation problem. It unifies liquidity across multiple blockchains and platforms, offering users access to a wide range of crypto assets and combines that with the speed, liquidity, and efficiency of centralized exchanges. But unlike CeFi, Flash Liquidity operates within a fully DeFi focused decentralized framework, ensuring that users remain in control of their assets at all times.

At the heart of Flash Liquidity is an innovative approach to liquidity provision. In traditional DeFi systems, liquidity providers (LPs) must lock up their assets in specific liquidity pools before any trading can occur. This ties up capital and exposes LPs to risks like impermanent loss—where the value of their locked assets can change unfavorably during trading. Flash Liquidity flips this model by enabling market makers to provide liquidity without locking up their capital on Radix until a trade is confirmed.

This “just-in-time” liquidity model significantly improves capital efficiency. Market makers can source liquidity from across the entire crypto ecosystem and only bring it onto Radix when a trade is finalized. This allows them to offer deeper liquidity with tighter spreads. This also makes Flash Liquidity particularly attractive to institutional players and professional traders, who require deep liquidity, speed, and flexibility to manage their operations profitably.

For end-users, Flash Liquidity offers permissionless access to a vast array of crypto assets, lower slippage (the difference between expected and actual trade prices), and tighter spreads (the gap between buy and sell prices). This results in a trading experience that can be built to be as smooth as a centralized exchange but with the added benefits of decentralized finance: transparency, security, and control over your assets.

Addressing DeFi’s Core Challenges

Flash Liquidity tackles some of the most pressing issues that have hindered DeFi’s growth:

1. Eliminating Asset Fragmentation: In traditional DeFi, tokens are often isolated within specific blockchains or platforms, forcing users to jump between ecosystems to access them. Flash Liquidity eliminates this problem by creating a unified system where all assets can be made accessible within Radix, regardless of where they originate. Whether a token is native to Radix or comes from another blockchain, users can trade it seamlessly within the Radix ecosystem.
   ‍

2. Unified Liquidity Across Platforms: Flash Liquidity consolidates liquidity from both CeFi and DeFi venues into the Radix ecosystem. This means users no longer need to switch between platforms to find liquidity; everything can be made available in one place, streamlining the trading experience and making it far more user-friendly.
   ‍

3. Capital Efficiency for Institutional Traders: Professional market makers and institutional traders play a critical role in providing deep liquidity and competitive pricing, but traditional DeFi liquidity provision requires them to lock up capital on-ledger before offering liquidity. Flash Liquidity solves this by allowing market makers to provide liquidity on demand. This ensures tighter spreads and deeper liquidity, benefiting institutional traders and the overall DeFi market.
   ‍

4. Seamless Integration with DeFi dApps: Liquidity powers decentralized applications (dApps), from decentralized exchanges (DEXs) to lending platforms and stablecoins. Flash Liquidity ensures that liquidity can easily integrate with other dApps on Radix, unlocking new opportunities for developers to innovate and build more robust financial applications.

Real-World Impact: How Flash Liquidity Works for Users

Let’s explore how Flash Liquidity benefits different types of users:

• Everyday Traders: Imagine you’re a trader looking to buy a token that isn’t native to Radix. Instead of needing to move assets to another ecosystem (or buy it on a centralized exchange), juggle bridges and wallets, and navigate multiple platforms, you can simply trade that token directly within Radix’s ecosystem at the same (or better) liquidity as you would find elsewhere. Flash Liquidity sources the liquidity for your trade from wherever it’s available, and the trade is executed instantly. There’s no need to manage multiple wallets or navigate fragmented liquidity—all of this is handled behind the scenes, making your trading experience seamless and efficient.
  ‍

• Professional Traders and Institutions: As a market maker, you want to provide liquidity without tying up capital across various platforms. Flash Liquidity allows you to offer liquidity only when needed. You can remain capital-efficient while offering deep liquidity and tight spreads, attracting more trading volume and increasing profitability. This flexibility makes Flash Liquidity particularly appealing to professional traders who need to maximize their resources.
  ‍

• DeFi Developers: For developers building DeFi applications, Flash Liquidity offers the ability to tap into global crypto liquidity without worrying about which chain an asset is on. Whether you’re developing a DEX, a lending platform, or a stablecoin project, Flash Liquidity ensures that your users have access to deep, reliable liquidity across the entire crypto ecosystem. This opens up new opportunities for innovation within the Radix DeFi ecosystem.

How Flash Liquidity Works

Flash Liquidity eliminates the inefficiencies of traditional liquidity pools by allowing market makers to make liquidity offers off-ledger, which can then be matched and executed on ledger. Here’s how it works:

1. Trade Execution: When a trade is confirmed on Radix, the token the user wants to trade for is minted against a line of credit held by the market maker with the token issuer. This ensures that the trade is executed immediately without waiting for liquidity to be moved on-chain.
   ‍

2. Settlement: Shortly after the trade is finalized, the market maker settles their line of credit by sending the underlying token to the token issuer. This minimizes capital lock-up while ensuring fast, efficient trades for the end user.
   ‍

3. Security and Efficiency: Flash Liquidity leverages intent-based order streaming to facilitate high-frequency trades off-chain before they get settled against a line of credit on-chain. This ensures liquidity providers can source liquidity from any trading venue without holding the tokens beforehand. This allows the market maker to offer liquidity across a huge range of tokens, minimizes risks like impermanent loss, and protects against MEV market manipulation tactics like front-running.

Instamint: The Technology Behind Flash Liquidity

Instamint, powered by Instabridge, is the engine that makes Flash Liquidity possible. Instabridge is a VASP regulated token-wrapping service that already supports major assets like BTC, ETH, USDC, and USDT on Radix. 

While part of Instabridge’s early mission was to bridge capital from everyday users onto Radix, the regulatory demands imposed by a tier 1 financial jurisdiction created significant user friction. 

However, that same regulatory framework is a critical prerequisite for doing business with prominent financial institutions, and the multi-year process to obtain the necessary regulatory approvals is finally going to pay off. 

Instamint allows market makers to mint wrapped assets on Radix as needed, using short-term lines of credit from Instabridge. This enables market makers to provide liquidity on demand and settle with the underlying assets as soon as they are obtained from the wider market. 

This system ensures that liquidity is always available when required, without locking up capital ahead of time and without burdening the user with having to worry about the mechanics of the process.

Institutions get a regulated counterparty with which to do business. Users get trustless access to a universe of tokens across the entire crypto ecosystem without having to worry about ever touching Instabridge.
