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 advanced 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 monetary 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 Individuals’s Cash”. This text is for merchants and potential traders seeking to consider the present panorama of institutional capital in DeFi. We is not going to be centered 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 government abstract:

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

  1. {Hardware} wallets

  2. Sensible 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 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 stay as much as its potential, this crowd will grow to be crucial. We consider that is price listening to.

Over the past hundred years, conventional markets have advanced 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 foundations are in the case of any given monetary services or products. These fashionable buildings shield traders from extreme monetary danger, inner collusion, theft, and different malfeasance. 

Over the previous few years, CeFi has began to pattern on this path (albeit via chapter and arrests) and as regulation comes into play, one might anticipate 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 property, operated both on-premise or on cloud-hosted companies, the place the pace of buying and selling and the safety of the property is ensured by just a few institutional operators.

The non-custodial nature of DeFi, nevertheless, makes managing capital at scale a tougher downside. If a “massive” DeFi fund (which as we speak would represent property on-chain of solely $40-100M) desires to actively commerce its guide, 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 property, 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. With a purpose to develop and attain mass adoption, DeFi might want to serve skilled fund managers, who serve you and I, and convey market effectivity and much-needed liquidity.

When Bitcoin emerged from the ashes of the International Monetary Disaster, certainly one of its extra common 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 deal with). The thought 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 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 non-public key on a telephone or pc is okay if there are only some hundred {dollars} within the account, however the calculus adjustments if that quantity is $10m or extra.

Till not too long ago, 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 similar to Coinbase, Anchorage, and Paxos will safeguard a non-public key and are available bonded and insured. The problem right here is that these custodians are primarily designed to hodl, and they also don’t realistically permit their purchasers to take part in DeFi. 

For traders who need on-chain publicity, there are 4 predominant 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 non-public 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 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 skill to work together with any DeFi protocol and on nearly any chain. They sometimes guarantee good non-public key safety, as a result of the non-public 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 listing 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 tough to behave rapidly, and doesn’t resolve 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 doubtless moved on or the harm is finished.

As an alternative of people, bots working on servers execute predefined buying and selling methods depending on numerous market situations. That is what most MEV merchants do. As an illustration, a bot might 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 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 resolve this entry downside, companies write good contracts that prohibit the full performance of the contract custodying the property. Consequently, even when a non-public key was compromised, a malicious actor couldn’t steal or redirect the funds to its personal deal with.

This method has traditionally been the one practical choice for automated buying and selling. Whereas it sufficiently protects the non-public key (or extra precisely, removes the singular dependence) and permits actual automation, it has one main draw back, specifically, companies want to write down, check, 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 rapidly to market situations, are slowed to the pace of an engineering staff who isn’t allowed to make errors.

2. It’s prohibitively costly to safe the lengthy tail of good contracts, and because of this, 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 the usage of CeFi custodians to handle non-public keys for DeFi funds.

The preferred choice for giant DeFi fund managers comes within the type of a crop of CeFi custodians that provide 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 danger and permits fund managers to present sure permissions to completely different customers on their staff. 

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 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 fundamental DeFi exercise, like yield farming, swapping, or lending however doesn’t anticipate to wish greater than a small handful of capabilities. 

3. The final group of custodians – finest exemplified by Fireblocks, Cactus, and Copper – model themselves as primarily “DeFi native” companies. They promote various 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 may set triggers for personalized 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. With a purpose to forestall malicious exercise, these companies 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 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 good contracts, whereas extending safety to each DeFi interplay” their coverage engines don’t really verify the habits of on-chain transactions – neither for handbook nor automated buying and selling. 

These companies solely verify 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 underneath the impression they’re being protected against theft or successfully separating buying and selling and administrative privileges once they in actual fact are usually not.

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

Over the past two years, DeFi native startups tackling “the transaction safety downside” have advanced into extra reliable service suppliers. There are, up to now, three teams of options, all with one factor in widespread – all of them take a “transaction simulation primarily based method”.

Simulating the transaction permits both an individual or a coverage engine to take 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, irrespective 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 relies 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 the majority companies already depend on a custodian and altering could be a massive headache.

2. Safety analytics options – Examples embrace 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 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) might supply one of the best of each worlds, however are additionally the latest 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 purchasers can select their very own custody resolution after which individually “plug in” this co-signer, which shops a further non-public key and rejects transactions routinely if they’re unsafe. 

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

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

2. A simulation-based coverage engine will not be inherently bulletproof. As with every safety system, there are methods to get it mistaken. The most typical method 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 one of the best, institutional companies ought to check 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 taking part in subject, which motivated our analysis on MEV. DeFi’s non-custodial design really gave particular person traders a head begin; even with the juicy yields of DeFi summer time, the custodial choices weren’t strong sufficient to justify the danger for fund managers. Nonetheless, that is beginning to change, and shall 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 following vital step. There’s at present plenty of give attention to creating higher wallets for retail customers with social restoration, however what’s equally wanted is a strong method 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.
