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 thus far 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 the 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 won’t be targeted on market hypothesis, however as an alternative survey the challenges merchants and traders face at present 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 primarily based approaches scored the very best throughout our metrics, whereas CeFi’s DeFi integrations seem to pose actual and poorly understood threats to their purchasers. This was our most shocking 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 turn into essential. We imagine that is value 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, massive authorized and technical methods element exactly what the principles are on the subject of any given monetary services or products. These fashionable buildings shield traders from extreme monetary threat, inside collusion, theft, and different malfeasance. 

Over the previous couple of years, CeFi has began to pattern on this course (albeit via chapter and arrests) and as regulation comes into play, one might count on the market to largely replicate this acquainted mannequin. Crypto is a unique asset class however the underlying market construction is comparably comparable: centralized possession of belongings, operated both on-premise or on cloud-hosted providers, 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, nevertheless, makes managing capital at scale a more difficult downside. If a “massive” DeFi fund (which at present would represent belongings on-chain of solely $40-100M) desires to actively commerce its e book, it runs into challenges round custody, commerce execution, and information integrity. We discover these nuances intimately under. By and enormous, the central downside 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 threat. 

DeFi’s core ethos is to construct a base monetary layer with open and equal entry for all traders. So as 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, one in all its extra fashionable memes was to “be your individual financial institution”. By public key cryptography, blockchains allow a string of characters (the personal key) to unilaterally management an account (the transaction outputs of a public handle). 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 providers with self-custody – trusting solely good contracts to execute predetermined commerce logic.

Permitting everybody to be their very own financial institution implies that everybody additionally must retailer their very own keys. Storing a personal key on a cellphone or pc is ok if there are only some hundred {dollars} within the account, however the calculus adjustments if that quantity is $10m or extra.

Till just lately, the one resolution for giant traders got here within the type of centralized custodians that feel and look like a extra conventional SaaS or monetary agency. Custodians reminiscent of Coinbase, Anchorage, and Paxos will safeguard a personal 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 enable their purchasers to take part in DeFi. 

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

Particular person merchants are sometimes snug utilizing a {hardware} pockets, like a Ledger, and storing the personal key someplace secure. The profit is that personal keys are offline, so even when a tool was compromised, no commerce may very well be executed. 

{Hardware} wallets are extremely versatile of their potential to work together with any DeFi protocol and on virtually any chain. They sometimes guarantee good personal key safety, as a result of the personal keys are usually not 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 record 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 Secure with a number of {hardware} pockets signers provides redundancy, but in addition makes it tough to behave shortly, and doesn’t remedy the core downside 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 working 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 seemingly moved on or the harm is completed.

As a substitute of people, bots working on servers execute predefined buying and selling methods depending on varied market situations. That is what most MEV merchants do. For example, a bot may very well be working a just-in-time (JIT) liquidity technique on Uniswap v3, the place it displays the general public mempool and instantly provides liquidity when it observes an enormous swap, to earn the LP swap charges. To do that, the bot server must retailer the personal keys, that means whoever has entry to the server has entry to the keys and all of the funds it controls. 

To resolve this entry downside, corporations write good contracts that limit the entire performance of the contract custodying the belongings. Consequently, even when a personal key was compromised, a malicious actor couldn’t steal or redirect the funds to its personal handle.

This strategy has traditionally been the one reasonable choice for automated buying and selling. Whereas it sufficiently protects the personal key (or extra precisely, removes the singular dependence) and permits actual automation, it has one main draw back, specifically, corporations want to put in writing, take a look at, and deploy a brand new good contract for each adjustment within the commerce, leading to two prohibitive issues:

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

2. It’s prohibitively costly to safe the lengthy tail of good contracts, and in consequence, it sometimes isn’t. There are common situations of MEV bot good contracts getting exploited. 

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

Automated buying and selling methods are important for {most professional} fund managers. But issues come up when automated commerce execution meets custody. One potential workaround being explored is using CeFi custodians to handle personal keys for DeFi funds.

The most well-liked choice for giant 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 (sometimes multi-party computation or MPC wallets), OTC buying and selling, and CeFi integrations. They provide a predefined coverage engine that manages threat and permits fund managers to provide sure permissions to totally different customers on their workforce. 

These CeFi custodians may be divided into three totally different teams. 

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

2. The second affords DeFi integrations via Metamask Institutional or another browser pockets. Utilizing these custodians – Bitgo, GK8 and Qredo, amongst others – is probably helpful for a fund that’s doing primary 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 primarily “DeFi native” corporations. They promote various versatile providers, together with a configurable coverage engine and automatic execution for DeFi methods. This hypothetically enable 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. So as to forestall malicious exercise, these providers apply a coverage engine that whitelists sure good contract addresses that merchants are allowed to work together with. The issue is that whereas they promote options reminiscent of 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 permits programmatic entry to good contracts, whereas extending safety to each DeFi interplay” their coverage engines don’t truly test the habits of on-chain transactions – neither for guide nor automated buying and selling. 

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

This vulnerability signifies that these corporations are including DeFi performance to an current product, fairly than constructing a DeFi-native system that understands the nuances of how blockchain transactions work. Nonetheless, there’s an rising {industry} of DeFi native suppliers which have one essential factor in frequent.

During the last two years, DeFi native startups tackling “the transaction safety downside” have developed into extra reliable service suppliers. There are, to date, three teams of options, all with one factor in frequent – all of them take a “transaction simulation primarily based strategy”.

Simulating the transaction permits both an individual or a coverage engine to take a look at the results of a transaction and decide 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 seemingly wish to reject that transaction.

The place these corporations differ, is their strategy 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. Not like the CeFi custodians, their coverage engine is predicated on transaction simulation. The upside is that they credibly shield their purchasers in DeFi, in distinction to the aforementioned custodians. The straightforward draw back is that almost all corporations already depend on a custodian and altering could be a massive headache.

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

3. Co-signers – DeFi Armor (disclosure, constructed by Eulith) might provide the very 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 personal key storage – their purchasers can select their very own custody resolution after which individually “plug in” this co-signer, which shops a further personal key and rejects transactions routinely if they’re unsafe. 

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

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

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

The underside line is whereas simulation-based approaches look like the very best, institutional corporations ought to take a look at these options earlier than relying on them for giant allocations.

We see the way forward for monetary methods in DeFi due to the implications of self-custody, inherent transparency, and permissionless entry. We’re involved with sustaining a good enjoying 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 chance for fund managers. Nonetheless, that is beginning to change, and can be an enormous web optimistic for the {industry}. 

To speed up this modification, and to assist DeFi to scale, the development of infrastructure specialised for traders to make use of is the subsequent vital step. There’s at the moment a whole lot of deal with growing higher wallets for retail customers with social restoration, however what’s equally wanted is a sturdy manner for institutional traders to entry DeFi with out compromising threat administration. Importantly, these improvements are being constructed on prime of blockchains, and don’t require a compromise on DeFi’s dedication to a permissionless monetary system.
