The Staircase, the Plateau, and the Dip: Reading Nine Months of Live DeFi Yield Data

We Measured Nine Months of Live Vault Data. Here’s What 18M FLOW in TVL and $210K in Profit Actually Looks Like

From 1,000 FLOW to 18M FLOW in TVL, ∼$210K in cumulative USD profit, and what nine months of share-price data tells us about real DeFi yield.

In August 2025, we deployed 1,000 FLOW tokens into our first live yield vault on the Flow blockchain. It was a proof-of-concept allocation; small enough to absorb any loss without consequence, large enough to give us real on-chain data to learn from.

Nine months later, that vault holds 18M in TVL and has generated roughly $210K in cumulative USD profit across its depositor base.

We could leave it there. Most protocols would. A two-sentence summary, a screenshot, and a marketing campaign built around the headline numbers.

But headline numbers are exactly the problem with how DeFi yield gets reported. So instead, this is a walk through what the data actually shows, including the parts that don’t flatter us, and what we think serious depositors should be looking at when they evaluate any yield product, ours included.

How we read the data

The same indexing infrastructure we use to evaluate external vaults, the one that produced our 29-vault stablecoin yield analysis published earlier this month, powers this internal review.

A vault’s reported APY can be computed in at least four different ways: trailing 7-day, trailing 30-day, instantaneous from utilization curves, or annualized from inception.

Each one is technically accurate. Each one tells you something different. None of them, on its own, tells you what depositors actually earned. The number that does is on-chain share price growth measured directly from the blockchain, across the full window the position was held. Everything else is an estimate.

So that’s what we measured. Two charts, two questions, both answered from on-chain data only.

The TVL story

The first chart shows total value locked from August 2025 through May 2026.

The shape is a staircase. Each visible step is a real depositor making a real allocation decision at a specific point in time, not a continuous curve produced by emissions or recursive minting.

A few things to read out of the shape

The curve isn’t smooth. Smooth exponential TVL growth in DeFi is almost always a signal of one of three things:

• token emissions distributing rewards continuously
• recursive cross-minting between protocols
• or fake volume from related wallets.

None of those are happening here. The staircase shape is what real, discrete depositor behavior looks like.

The early period; August through October, climbs in small steps from roughly 3M to 5M FLOW TVL. This is what we’d call the trust-establishment phase. Early depositors, mostly from the existing community, allocating in size large enough to be meaningful but small enough to test the product.

In early November, the curve steps vertically from 7M to 10M. This was a single significant deposit window. Trust had been earned. Larger allocators were now willing to size up.

The period between November and March looks flat. It isn’t.

TVL ranged between 9M and 10M FLOW, with a brief dip in late December that recovered within weeks.

This was an intentional plateau on our end. We had reached a capacity limit on the underlying strategies and paused new deposits until allocation infrastructure could scale.

From late March onwards, the curve accelerates again. By May, TVL crossed 18M.

The full nine-month range shows three discrete growth phases separated by deliberate pauses. We mention this because the most common question we get from institutional readers is:

“Can you absorb a large allocation without breaking the strategy?”

The answer is in the chart. When we couldn’t, we paused. When we could, we grew.

The profit story

The second chart below shows cumulative profit denominated in both FLOW and USD over the same period.

The FLOW line climbs steadily from zero to approximately 1.45M FLOW in cumulative profit. The shape is almost linear, which is the visual signature of yield generated from real economic activity rather than token incentives.

Emission-driven yield decays as the token decays, causing its profit curve to flatten or roll over.

Real yield from lending spreads, funding rate differentials, and trading fees compounds in a roughly straight line because the underlying economic activity is continuous.

The USD line climbs less steeply at first, then accelerates from December onwards as FLOW appreciated against the dollar through the first quarter of 2026. The two lines diverge in our favor during this period; depositors captured both yield and token appreciation.

There is one visible imperfection.

In late February 2026, both lines dip. The strategy briefly retraced in FLOW terms. The USD line dropped further because FLOW price was also volatile in the same window. It recovered within three weeks. No emergency communication, no broken peg, no governance crisis. The strategy did what it was designed to do under stress.

We’re flagging it because we’d flag it if we were analyzing someone else’s vault. A reader who notices it and asks about it is exactly the kind of depositor we want.

What the numbers mean in context

Three observations from nine months of live 

Real yield doesn’t need a marketing campaign to keep growing. The FLOW-denominated profit line is nearly linear over nine months because nothing about the yield mechanism depends on speculation, incentive cycles, or new depositor inflows.

The same vault running with the same strategies would produce the same line whether TVL was 1M or 20M, scaled proportionally.

Real depositor behavior shows up as steps, not curves. If you’re evaluating any yield product, look at the shape of its TVL chart. Smooth exponential growth is almost always engineered. Discrete steps mean capital arrived because someone made a decision to allocate. The former is a marketing chart.

The latter is a track record.

Drawdowns happen. The question is what the recovery looks like. The February dip is the single visible negative event in the entire dataset. It is small (under 5% in FLOW terms), brief (recovered in three weeks), and didn’t require any emergency intervention. This is what well-managed strategy risk looks like.

Protocols that claim zero drawdowns are either too new to have experienced one or are computing returns in ways that obscure them.

How this connects to ayUSD

We’re publishing this because the data is genuinely interesting and the methodology is replicable.

We’re also publishing it because ayUSD; our stablecoin yield product launching on Flow EVM, with cross-chain deposits routed via LayerZero and planned expansion to Ethereum, Arbitrum, and Base, is built on the same engine that produced these nine months of FLOW results.

ayUSD is a single liquid token that routes stablecoin deposits across a diversified portfolio of real DeFi yield strategies: lending spreads, funding rate arbitrage, options premiums, verified through on-chain APY verification rather than aggregator data.

The allocation logic, risk thresholds, and drawdown controls are the same ones that produced the FLOW chart you just read.

The point isn’t that past FLOW performance guarantees future ayUSD performance. It doesn’t. The point is that the methodology, the discipline, and the transparency you’ve just seen applied to nine months of FLOW data is what gets applied to every ayUSD allocation decision.

If you want to evaluate a stablecoin yield strategy by the same standard, the data is here and the methodology is replicable.

What’s next?

This becomes a recurring publication. Every month we’ll publish updated on-chain performance TVL, share price growth, drawdown events, and rebalance activity, across both ayFLOW and, once launched, ayUSD.

The goal is straightforward: build a permanent public record that any depositor, allocator, or institutional reader can use to evaluate what AlphaYields is doing with their capital, in their own time, against their own benchmarks.

The space gets better when more protocols publish this kind of data. We’d rather be the protocol that started doing it than the one that gets asked why we didn’t.

ayFLOW is live on the Flow blockchain. ayUSD launches on Flow EVM with cross-chain access via LayerZero, expanding to Ethereum, Arbitrum, and Base.
