Intro

So what is the current state of decentralized finance? Where are we with different scaling solutions on Ethereum? How about DeFi on other chains? And what is the most likely scenario when it comes to the future of DeFi? You’ll find answers to these questions in this article. 

And one more thing before we start, Finematics has recently hit 100,000 subscribers on Youtube! This is pretty amazing and I’d like to say a big thank you to all of you watching my videos and reading my articles. Also a special shout out to all of our Patrons who actively support this channel.

DeFi – State of Affairs 

Decentralized Finance, together with the whole cryptocurrency space, started 2021 with a bang. 

In just a few months the total value locked in DeFi grew from around $15B to an astonishing $45B. 

The volume on decentralized exchanges has also been at an all-time high with over $50B traded each month. 

On top of this, a lot of DeFi tokens have seen a significant increase in value which attracted even more people to this still very new space. 

We’ve also seen a lot of development. 

New projects popping up pretty much every day. 

Already existing protocols launching their new versions. 

Other well-known projects migrating or announcing their migration to different scaling solutions.  

We also had some big news. For example, Visa announced they will start settling transactions in USDC on Ethereum. This is amazing not only for Ethereum but also for the whole DeFi space in general. 

Despite all of this development, it seems like DeFi is at a crossroad. 

On one hand, we have DeFi protocols on Ethereum exploring multiple different scaling solutions to alleviate high transaction fees. On the other hand, we have other chains trying to attract both the new and the already existing DeFi projects. 

Scaling DeFi 

When it comes to scaling DeFi on Ethereum we have quite a few options either already available or not being too far from a full launch.

These options belong to one of the 2 categories: Layer 2 scaling and sidechains. 

Layer 2 scaling relies on the security of the main layer – the Ethereum blockchain. 

Sidechains rely on their own security models, usually by having a separate consensus mechanism. They can also have additional security guarantees that leverage the main layer, but despite this, they are usually considered less secure than Layer 2 solutions. 

One of the most discussed Layer 2 options, when it comes to DeFi, are rollups. 

Rollups provide scaling by executing transactions outside of Layer 1 but posting transaction data on Layer 1 which allows rollups to be secured by the main Ethereum chain. 

There are 2 types of rollups: optimistic rollups and ZK rollups. 

Optimistic rollups run an EVM-compatible virtual machine which allows for executing the same smart contracts as on Ethereum. Optimism and Arbitrum are currently the most popular options. 

Optimism has been partially rolled out to the Ethereum mainnet with a limited set of partners to ensure that the technology works as expected.

Synthetix has already migrated its staking module to Optimism which allows for minting sUSD and receiving staking rewards in a fast, cheap and secure way. 

Another big partner that has already announced its launch on Optimism is Uniswap with its long-awaited Uniswap V3.

Arbitrum, on the other hand, seems to be even closer to being fully launched on the Ethereum mainnet. They partnered with a few major DeFi projects like Augur and Bancor. 

ZK rollups, although faster and more efficient than optimistic rollups, do not provide an easy way for the existing smart contracts to migrate to Layer 2 – at least not just yet. 

With ZK rollups we have a few options available, mainly StarkWare and ZKSync. 

StarkWare-based rollups are already extensively used by projects such as DeversiFi, Immutable X and dYdX. 

ZKSync is working on an EVM-compatible virtual machine that will be able to fully support any arbitrary smart contracts written in Solidity. They are targeting August for their mainnet release.

Besides Layer 2 options, we have sidechains like the Matic PoS chain or the xDai chain. 

We’ve recently seen a lot of projects launching on both of these chains. This includes Sushiswap, Polkamarkets and Aave on the Matic PoS chain and Perpetual Protocol, RealT and Gnosis on xDai. Both chains are also integrated with Chainlink oracles. 

Matic, after its recent rebranding to Polygon, also aims at expanding its available scaling solutions and add things like ZK and optimistic rollups, on top of already available solutions: the PoS chain and the Plasma chains. 

Although Layer 2 scaling and sidechains can alleviate high transaction fees and increase both the throughput and speed of transactions they come with their own challenges. 

The biggest one, that can negatively affect DeFi, is the lack of smart contract composability between different scaling solutions.

Composability is clearly one of the most important characteristics of DeFi. When it comes to the Ethereum main chain, a single transaction can interact with multiple different DeFi protocols. For example, a smart contract can borrow funds on Aave, swap these borrowed coins to other ones on Uniswap and provide the swapped coins to a yield farming aggregator – all of this in one single Ethereum transaction. 

Although composability is still possible within one scaling solution, it would break if even one of these protocols is not available on this particular scaling solution. 

Continuing with our previous example, if Aave is only additionally available on Matic PoS and Uniswap is only available on Optimism, we wouldn’t be able to compose one transaction that calls both the Aave’s and Uniswap’s smart contracts in any way outside of the Ethereum main chain.

The next issue is the interoperability between different scaling solutions.

What if we borrowed funds on Aave on the Matic PoS Chain but we later want to swap them using Uniswap on Optimism. At the moment we’d have to withdraw them to the Ethereum main chain before being able to use the coins on Optimism. This of course adds a lot of friction as some withdrawals can take a long time to be fully settled especially when it comes to optimistic rollups. 

Having multiple scaling solutions also provides us with some challenges when it comes to the existing liquidity in DeFi. Instead of having a lot of liquidity available on the Ethereum main chain in a few major protocols, we’ll see the existing liquidity being split across the Ethereum main chain, multiple implementations of rollups and different sidechains. 

Fortunately, most of these challenges are solvable. 

We’ll probably see a lot of bridges between different scaling solutions which should help with reducing friction. On top of this, the other approach is to create a whole ecosystem that is interoperable by default. This is the approach that Polygon decided to go with. 

Also, it looks like most liquidity outside of Layer 1 will concentrate around a few most popular scaling options with the biggest number of high-quality DeFi protocols available. 

Despite the existing and future challenges, Ethereum is clearly an undisputed leader when it comes to DeFi. It offers credible neutrality, decentralization and a strong community, driven not only by the recent price rise of ETH but even more about building the future of finance and web3. 

When it comes to DeFi on other chains there are also a few options available. 

BSC And DeFi On Other Chains

Let’s start with Binance Smart Chain – yes, I know, BSC is not always even considered as DeFi and more like CeDeFi and you can find more about it here in this article

Nevertheless, BSC attracted a lot of users and trading volume in a very short period of time. 

BSC, as a fork of Ethereum, allows for deploying the same smart contracts as the ones already available on Ethereum. 1inch and Alpha Homora are some of the projects that decided to expand their reach and launch on BSC in parallel to Ethereum.  

Besides Binance Smart Chain, there are a lot of other chains that come with their own security models and different levels of decentralization. 

Many also put a lot of effort into building their own DeFi ecosystem, including Solana with its decentralized exchange – Serum, Avalanche with Pangolin and even Bitcoin where DeFi can be built on top of sidechains. 

The challenges with all of these blockchains are similar to the challenges of different scaling solutions on Ethereum, mainly the lack of composability and interoperability. 

Fortunately enough, there are also a few other projects that focus predominantly on these problems. 

Cosmos aims at creating “The Internet Of Blockchains” by leveraging its inter-blockchain communication protocol. 

Polkadot, on top of its parachains technology that allows for creating sovereign blockchains, also aims to make bridging to the external blockchains easier.

Thorchain focuses on cross-chain liquidity and decentralized exchange of assets between different blockchains.

With all of these options within the Ethereum ecosystem, and outside of it, most people feel lost trying to answer the question – what will DeFi look like in the future. 

The Truth 

Although it seems like DeFi is at a crossroad, in practice we’re just experiencing an ongoing Cambrian Explosion of this nascent space. 

The truth is, that at this point, no one can be certain what the future of DeFi will look like.

What we can pretty much assume though is that every single potential solution will be explored. Some of them will survive and thrive while others will become irrelevant over time. 

DeFi on Ethereum with different Layer 2 options and sidechains; DeFi and CeDeFi on other chains; interoperability between blockchains or maybe something completely new: It’s almost guaranteed that all of this will be tried and after some time we’re going to end up with the most adopted and hopefully most decentralized working solution.

And even though some people may not like it, this is the beauty of DeFi and any other open ecosystems like this. 

The exact details might still be quite vague, but the future of the whole DeFi space is brighter than ever. DeFi is here to stay. We may not be 100% sure of its final form, but it is almost certainly the future of finance. 

One thing that can be used to indicate which projects and ideas are here to stay more than anything else is the next, most likely inevitable, bear market. During this time most bad ideas and projects without strong communities die off and the remaining users concentrate around the best, long-lasting protocols. 

When it comes to individual DeFi projects, some of them will thrive and capture value across multiple scaling solutions or even across multiple blockchains. Others won’t be able to do it and new protocols will be able to steal their market share.

Because of this ever-changing space, it’s really important to keep learning and expanding our knowledge about DeFi, crypto, finance and technology in general.
