DeFi’s OPM period: The custody hurdle

Co-written with Lucas Gaylord, co-founder & CEO of Eulith, which builds on-chain buying and selling infrastructure for skilled merchants

DeFi has to this point been dominated by traders with both area of interest technical know-how, or sufficient hubris to fly blind. But when buying and selling goes past a browser plugin to institutional ranges, a myriad of points come up. The truth is, DeFi has developed for a market of particular person merchants managing their very own capital, however operational challenges come up when “OPM” comes into play. For the reason that starting of economic markets, and throughout all asset lessons and market cycles, merchants have tended in direction of utilizing increasingly more OPM. For these unfamiliar with the time period, OPM lovingly stands for, “Different Folks’s Cash”. This text is for merchants and potential traders trying to consider the present panorama of institutional capital in DeFi. We is not going to be targeted on market hypothesis, however as an alternative survey the challenges merchants and traders face as we speak and the way it impacts you.

Right here’s an govt abstract:

• There are roughly 4 institutional methods to custody in DeFi:

  1. {Hardware} wallets

  2. Good contracts and buying and selling bots

  3. CeFi’s DeFi integrations

  4. Simulation-based approaches

• Simulation based mostly approaches scored the very best throughout our metrics, whereas CeFi’s DeFi integrations seem to pose actual and poorly understood threats to their shoppers. This was our most stunning discovery.

• DeFi continues to be maturing. There’s a small however rising {industry} {of professional} merchants and fund managers in DeFi. If DeFi is to reside as much as its potential, this crowd will change into essential. We imagine that is price listening to.

During the last hundred years, conventional markets have developed to implement the separation of buying and selling and administrative privileges at each layer of the group. Moreover, giant authorized and technical techniques element exactly what the principles are with regards to any given monetary services or products. These fashionable constructions shield traders from extreme monetary danger, inner collusion, theft, and different malfeasance. 

Over the previous few years, CeFi has began to development on this course (albeit by chapter and arrests) and as regulation comes into play, one could count on the market to largely replicate this acquainted mannequin. Crypto is a special asset class however the underlying market construction is comparably related: centralized possession of belongings, operated both on-premise or on cloud-hosted companies, the place the velocity of buying and selling and the safety of the belongings is ensured by a number of institutional operators.

The non-custodial nature of DeFi, nonetheless, makes managing capital at scale a more difficult drawback. If a “giant” DeFi fund (which as we speak would represent belongings on-chain of solely $40-100M) needs to actively commerce its guide, it runs into challenges round custody, commerce execution, and knowledge integrity. We discover these nuances intimately under. By and enormous, the central drawback is how a fund manages its transaction safety, which in CeFi is encompassed by custody of the belongings, however in DeFi takes on a broader context. In assessing their choices, DeFi fund managers – and maybe extra importantly – their LPs are affected by a tradeoff between transaction safety, automated execution (e.g. a stop-loss button), and the power to dynamically alter danger. 

DeFi’s core ethos is to construct a base monetary layer with open and equal entry for all traders. As a way to develop and attain mass adoption, DeFi might want to serve skilled fund managers, who serve you and I, and produce market effectivity and much-needed liquidity.

When Bitcoin emerged from the ashes of the International Monetary Disaster, considered one of its extra well-liked memes was to “be your individual financial institution”. By way of public key cryptography, blockchains allow a string of characters (the non-public key) to unilaterally management an account (the transaction outputs of a public tackle). The concept is summed up within the phrase “your keys, your crypto”. With Bitcoin, the one factor to do is hodl, which doesn’t spur a lot of a conducive monetary system. DeFi picked up the place Bitcoin left off and facilitated buying and selling, lending, and different monetary companies with self-custody – trusting solely sensible contracts to execute predetermined commerce logic.

Permitting everybody to be their very own financial institution signifies that everybody additionally must retailer their very own keys. Storing a non-public key on a telephone or pc is ok if there are just a few hundred {dollars} within the account, however the calculus adjustments if that quantity is $10m or extra.

Till lately, the one resolution for big traders got here within the type of centralized custodians that feel and appear like a extra conventional SaaS or monetary agency. Custodians similar to Coinbase, Anchorage, and Paxos will safeguard a non-public key and are available bonded and insured. The difficulty right here is that these custodians are primarily designed to hodl, and they also don’t realistically permit their shoppers to take part in DeFi. 

For traders who need on-chain publicity, there are 4 fundamental custody choices, as proven within the desk above. From this, it’s clear that there’s no good resolution as all of them contain tradeoffs between non-public key safety, automated execution, and the power to simply modify buying and selling methods.

Particular person merchants are usually comfy utilizing a {hardware} pockets, like a Ledger, and storing the non-public key someplace secure. The profit is that personal keys are offline, so even when a tool was compromised, no commerce might be executed. 

{Hardware} wallets are extremely versatile of their capability to work together with any DeFi protocol and on nearly any chain. They usually guarantee good non-public key safety, as a result of the non-public keys will not be simply compromised. The draw back is that they’re not scalable and most significantly – people don’t learn EVM bytecode, which has led to the lengthy checklist of hacks and theft headlining search outcomes. Nonetheless, this can be a practical setup for a small-ish DeFi fund doing principally easy swaps or yield farming. Utilizing a Gnosis Protected with a number of {hardware} pockets signers provides redundancy, but additionally makes it troublesome to behave rapidly, and doesn’t remedy the core drawback of screening for probably malicious transactions (for which there are answers described under). Importantly, multi-signature wallets allow solely a half-solution to the issue of separating administrative and buying and selling privileges. 

Whereas some DeFi funds could also be content material with swapping and yielding, others are operating extra advanced methods throughout a number of protocols and chains. Human signatories can’t be relied upon right here. Within the time it takes to provoke and signal a transaction, the chance has doubtless moved on or the harm is completed.

As a substitute of people, bots operating on servers execute predefined buying and selling methods depending on numerous market circumstances. That is what most MEV merchants do. As an example, a bot might be operating a just-in-time (JIT) liquidity technique on Uniswap v3, the place it screens the general public mempool and instantly provides liquidity when it observes a giant swap, to earn the LP swap charges. To do that, the bot server must retailer the non-public keys, which means whoever has entry to the server has entry to the keys and all of the funds it controls. 

To unravel this entry drawback, companies write sensible contracts that prohibit the overall performance of the contract custodying the belongings. Consequently, even when a non-public key was compromised, a malicious actor couldn’t steal or redirect the funds to its personal tackle.

This method has traditionally been the one lifelike possibility for automated buying and selling. Whereas it sufficiently protects the non-public key (or extra precisely, removes the singular dependence) and allows actual automation, it has one main draw back, specifically, companies want to put in writing, take a look at, and deploy a brand new sensible contract for each adjustment within the commerce, leading to two prohibitive issues:

1. Hedge funds, whose survival is based on reacting rapidly to market circumstances, are slowed to the velocity of an engineering crew who isn’t allowed to make errors.

2. It’s prohibitively costly to safe the lengthy tail of sensible contracts, and because of this, it usually isn’t. There are common situations of MEV bot sensible contracts getting exploited. 

In essence, it’s kicking the private-key-can down the proverbial smart-contract-road.

Automated buying and selling techniques are important for {most professional} fund managers. But issues come up when automated commerce execution meets custody. One potential workaround being explored is the usage of CeFi custodians to handle non-public keys for DeFi funds.

The most well-liked possibility for big DeFi fund managers comes within the type of a crop of CeFi custodians that supply DeFi integrations. These service suppliers’ core merchandise are their custody options (usually multi-party computation or MPC wallets), OTC buying and selling, and CeFi integrations. They provide a predefined coverage engine that manages danger and permits fund managers to offer sure permissions to completely different customers on their crew. 

These CeFi custodians could be divided into three completely different teams. 

1. The primary gives essentially the most vanilla on-chain companies, like staking and on-chain governance. They’re firmly rooted in a “security first” method, however at the price of minimal performance. Anchorage Digital is one of the best instance. 

2. The second gives DeFi integrations by Metamask Institutional or another browser pockets. Utilizing these custodians – Bitgo, GK8 and Qredo, amongst others – is probably helpful for a fund that’s doing fundamental DeFi exercise, like yield farming, swapping, or lending however doesn’t count on to want greater than a small handful of features. 

3. The final group of custodians – greatest exemplified by Fireblocks, Cactus, and Copper – model themselves as basically “DeFi native” companies. They promote numerous versatile companies, together with a configurable coverage engine and automatic execution for DeFi methods. This hypothetically permit programmatic entry to on-chain contracts and code which might set triggers for custom-made liquidity administration, commerce execution, or exit methods.

The third group is crucial, because it advertises the performance that’s essential to  commerce professionally on-chain. As a way to stop malicious exercise, these companies apply a coverage engine that whitelists sure sensible contract addresses that merchants are allowed to work together with. The issue is that whereas they promote options similar to the power “to deploy systematic DeFi methods whereas sustaining the very best degree of fund safety on an institutional-grade platform” and an API “that allows programmatic entry to sensible contracts, whereas extending safety to each DeFi interplay” their coverage engines don’t truly examine the habits of on-chain transactions – neither for guide nor automated buying and selling. 

These companies solely examine excessive degree ‘to’ and ‘from’ fields of a DeFi transaction, ignoring its habits (encoded in what known as the “calldata”). This method is the safety equal of asking for one’s DOB on sure grownup web sites… Consequently, companies and their traders are sometimes below the impression they’re being shielded from theft or successfully separating buying and selling and administrative privileges once they in truth will not be.

This vulnerability signifies that these companies are including DeFi performance to an current product, quite than constructing a DeFi-native system that understands the nuances of how blockchain transactions work. Nevertheless, there may be an rising {industry} of DeFi native suppliers which have one essential factor in widespread.

During the last two years, DeFi native startups tackling “the transaction safety drawback” have developed into extra reliable service suppliers. There are, thus far, three teams of options, all with one factor in widespread – all of them take a “transaction simulation based mostly method”.

Simulating the transaction permits both an individual or a coverage engine to have a look at the results of a transaction and choose whether or not it’s safe. For instance, if because of the transaction, funds find yourself in an account you’ve by no means seen, regardless of the way it occurred, you doubtless need to reject that transaction.

The place these companies differ, is their method to custody and personal key storage. There are roughly three classes:

1. Custodians – Fordefi is a direct competitor to the likes of Fireblocks, Cactus, and Copper for his or her DeFi enterprise. In contrast to the CeFi custodians, their coverage engine is predicated on transaction simulation. The upside is that they credibly shield their shoppers in DeFi, in distinction to the aforementioned custodians. The straightforward draw back is that the majority companies already depend on a custodian and altering generally is a huge headache.

2. Safety analytics options – Examples embody Pocket Universe for people and Hypernative, Redefine, Hexagate, and others for establishments. These options present their shoppers with visible queues earlier than a transaction takes place, permitting shoppers to keep away from excessive danger transactions. These companies, in distinction to the custodians, don’t handle any non-public key materials, making them extra of a “safety advisor” than a custodian.

3. Co-signers – DeFi Armor (disclosure, constructed by Eulith) could supply one of the best of each worlds, however are additionally the most recent of those three classes with DeFi Armor being maybe the one product on this area of interest sub-industry. As is the case with the above two classes, they provide a simulation-based coverage engine. The distinction is in non-public key storage – their shoppers can select their very own custody resolution after which individually “plug in” this co-signer, which shops an extra non-public key and rejects transactions mechanically if they’re unsafe. 

Whereas our analysis signifies simulation-based approaches are one of the best we’ve got, they’re not a silver bullet both. There are two fundamental downsides to pay attention to:

1. A transaction simulation can take as much as a number of seconds, which is simply too sluggish for sure high-frequency methods. In these situations companies are again to rolling their very own sensible contract safety.

2. A simulation-based coverage engine isn’t inherently bulletproof. As with every safety system, there are methods to get it improper. The most typical approach is ignoring the potential penalties of pre-trade state-change (a subject for one more article!).

The underside line is whereas simulation-based approaches seem like one of the best, institutional companies ought to take a look at these options earlier than relying on them for big allocations.

We see the way forward for monetary techniques in DeFi due to the implications of self-custody, inherent transparency, and permissionless entry. We’re involved with sustaining a good taking part in area, which motivated our analysis on MEV. DeFi’s non-custodial design truly gave particular person traders a head begin; even with the juicy yields of DeFi summer season, the custodial choices weren’t sturdy sufficient to justify the danger for fund managers. Nevertheless, that is beginning to change, and can be an enormous web optimistic for the {industry}. 

To speed up this transformation, and to assist DeFi to scale, the development of infrastructure specialised for traders to make use of is the following vital step. There’s at present lots of deal with creating higher wallets for retail customers with social restoration, however what’s equally wanted is a strong approach for institutional traders to entry DeFi with out compromising danger administration. Importantly, these improvements are being constructed on high of blockchains, and don’t require a compromise on DeFi’s dedication to a permissionless monetary system.
