Rebuilding Compound's Growth Engine on Arbitrum

The Situation

Compound shipped V3 and then went quiet. The founding team had moved on, and the protocol was left running on governance alone: a working product with no one steering its growth. A headless protocol, and V3 effectively an orphan product.

The timing was unforgiving. Capital and attention were migrating to L2s, and lending markets that failed to follow lost mindshare, integrations, and eventually deposits. Compound was ceding ground to faster-moving competitors with no operator holding the line.

AlphaGrowth took over Compound's growth mandate. The first priority was distribution: get Compound onto the chains where users and liquidity were actually moving. Arbitrum, with the deepest liquidity of any L2 and an active DAO incentive program, was the clearest target.

The Grant

AlphaGrowth led Compound's application into Arbitrum's Long Term Incentives Pilot Program (LTIPP), a 45M ARB program pool, and secured a 1.8M ARB grant. It was the largest single award of that funding cycle, close to double the next-largest allocation.

For a protocol that had spent the prior stretch on the back foot, this was its first major external win in years. It reset the narrative. Compound was building again, and a major DAO had just put real capital behind that.

The Constraint That Became The Strategy

There was a catch in the terms. The grant had to reach Compound users on a fixed schedule, streamed in tranches. But Compound had no native mechanism to distribute incentives. The protocol simply was not built to hand out rewards, least of all on a third-party chain.

AlphaGrowth treated that as a forcing function rather than a blocker. Moving the incentives at all meant sourcing and wiring up external distribution infrastructure, and that infrastructure had to connect Compound to the rest of the Arbitrum ecosystem. The requirement pushed Compound outward instead of inward. A blessing in disguise.

Expanding the surface area

Before the campaign, Compound on Arbitrum had almost no distribution partners. The chain's lending and yield landscape behaved like a set of closed borders: protocols rarely composed with one another, and structured products, while they existed, were niche rather than mainstream.

The incentive flow gave every other team a concrete reason to build around Compound, upstream and downstream. That pulled in:

• Structured products and yield vaults routing deposits into Compound markets
• Wallets surfacing Compound yield directly to their end users
• Centralized-exchange earn products using Compound as a backend (notably an OKX onboarding channel)
• Carry-trade and yield strategies built on top of Compound positions

The net effect: Compound moved from an isolated market to one of the most tightly integrated lending venues on Arbitrum. The integrations, not the emissions, were the durable asset.

The Results

Over the program window, Compound V3's TVL on Arbitrum climbed from a pre-incentive base of roughly $40M to a peak of about $213M — a near-fivefold move. Growth concentrated where the incentives pointed: stablecoin markets, carry-trade structures, and yield strategies.

Compound V3 — Total Value Locked on Arbitrum

The composability mattered as much as the headline number. Because the campaign was built through integrations rather than a pure emissions dump, much of the deposit base arrived attached to real product surfaces, rather than parking as mercenary capital waiting for the rewards to stop.

Independent validation: the Castle Labs retention study

In August 2025, Castle Labs — research member of the Arbitrum Research & Development Collective (ARDC) — published a dedicated retention study using Compound's 1.8M ARB grant as its case study. This is the meaningful signal: of all the LTIPP grants, a respected research firm chose Compound's program as the worked example for how to measure incentive quality.

Crucially, the study is methodological, not promotional. It segments deposits into pre-incentive, incentive, and post-incentive phases and tracks cohorts over time rather than reading headline TVL. That makes its positive findings for Compound more credible, not less.

01. Incentives drove gains and retained capital
The program lifted deposits sharply and, unlike many emissions campaigns, kept a meaningful share of that capital after rewards tapered.

02. A high-value cohort delivered outsized impact
A relatively small group of retained, high-value users accounted for a disproportionate share of lasting value.

03. The OKX onboarding channel had a positive effect
Routing acquisition through a CEX earn product brought in users whose behaviour and retention compared favourably to the general cohort.

04. Stablecoin markets retained best
USDC and USDT markets held users more reliably than volatile-asset markets — useful guidance for where to point future incentives.

05. Most users still exit within ~6 months
Churn is the default across DeFi incentive programs; durable retention is the exception that has to be engineered for.

06. Lasting success tracks supply-to-utilisation
Deposits only compound into durable value when they convert into borrowing and active use, not idle supply.

07. Cohort analysis beats top-line TVL
Retention segmentation reveals what headline numbers hide: which growth is sticky and which is mercenary.

The takeaway the study lands on: judge incentive programs by retained, segmented behaviour — not by the TVL spike alone.

Benchmarked Against the Cohort: OpenBlock Labs LTIPP Analysis

In October 2024, OpenBlock Labs — Arbitrum's data-monitoring partner for both STIP and LTIPP — published its post-mortem on grantee performance. The report's discipline matters: each protocol's outcome was measured against a control group constructed from the same protocol's performance on other chains, isolating the effect of the ARB incentives from the broader market. Two metrics anchor the analysis: the change in 7-day moving average supply TVL across the incentive window, and the dollars of TVL produced per dollar of ARB utilized.

Methodology note: OpenBlock uses gross supply TVL (the lending side only), distinct from the DeFiLlama net-TVL view (deposits minus borrows) shown in the chart above. The two paint the same growth story through different lenses. On OpenBlock's framing, Compound's 7D MA supply TVL ran from $92M to $266M across the incentive window — a 188% increase — at a capital efficiency of $139 in supply TVL per $1 of ARB utilized.

Compound vs. other LTIPP grantees (per OpenBlock)

Two things stand out. First, Compound produced more supply TVL per dollar of ARB than any other named protocol in the report — roughly 1.35× more than Beefy and over 4× more than Synthetix. Second, and more important: OpenBlock specifically flagged Compound's stablecoin deposits as the durable, "sticky" outcome that the lending sector otherwise failed to produce. The general lending sector oscillated and underperformed after LTIPP; the yield aggregators that gained the most lost it all back; Compound was the exception that held.

Read together with the Castle Labs retention study published ten months later, the picture is consistent: two independent research firms, using different methodologies, identified Compound's LTIPP program as the one that produced retained capital where most did not. That is the result incentive programs are designed to achieve and rarely do.

What Arbitrum Got Out Of It

The benefit ran both ways. Arbitrum's DeFi became measurably more interconnected. Protocols stopped behaving as isolated silos of user interaction and started behaving as pieces of a larger system, each one enhancing the experience of the others. A deposit in one venue could now flow through Compound and into a structured product or a wallet's yield feature without leaving the ecosystem.

That is the version of incentive spending DAOs actually want: capital that builds connective tissue and converts into utilisation, not just a temporary TVL spike that unwinds the day emissions stop. The fact that the campaign became the reference case for how to measure incentive quality is the clearest endorsement of how it was run.

In Short

AlphaGrowth inherited a protocol without a captain and turned a single grant into an ecosystem position. The 1.8M ARB was the catalyst. The integrations were the actual product. Compound came out woven into Arbitrum, Arbitrum came out a more composable place to deploy capital, and independent research came out treating the program as the worked example. That is the playbook: win the incentives, then spend them in a way that compounds long after the emissions end.

Why This Matters Here

The same playbook, pointed at a new ecosystem

What worked for Compound on Arbitrum was not the size of the grant. It was the operating model around it: secure ecosystem incentives, then deploy them through integrations and distribution partners so the capital builds composability instead of evaporating. That is precisely the work a chain needs when it wants its DeFi ecosystem to behave as a connected system rather than a set of isolated apps. It is the model AlphaGrowth proposes to bring to Cardano.
