About AprScope

What this site is

AprScope is an independent aggregator of yield-bearing positions across decentralized finance. We track approximately 19,000 active pools across 95 chains, refreshed hourly from on-chain data, and present the results with structured risk notes and historical charts on every page.

The goal is simple: replace the bookmark-juggling that careful DeFi users do (DefiLlama for TVL, Dune for cohort analysis, individual protocol dashboards for current rates, Twitter for incident reports) with a single page per pool that shows what you actually need to know before you deposit.

Who runs it

AprScope is built and maintained by Vladimir Kayzumov. The site is owned and operated as a personal project, not a company; there is no team, no funding, no investor commitments shaping the editorial direction. Decisions about what to track, how to present it, and what to caveat are mine.

How we make money

The site is currently free and ad-free. As traffic grows, we intend to add:

Display advertising through Google AdSense or a similar non-intrusive network. Ads will be clearly marked and never disguised as editorial content.
Affiliate links to non-protocol services we think are useful, such as hardware wallets (Ledger, Trezor) and crypto tax software (Koinly, CoinTracker). Affiliate links will always be disclosed at the point of recommendation.
Direct sponsorships from DeFi protocols, only if the relationship can be disclosed without compromising the integrity of the rankings or risk notes.

We do not, and will never:

Accept payment to inflate a protocol’s rank, hide negative information, or influence which pools appear on the homepage.
Run “promoted” or “featured” pool placements that aren’t algorithmically determined.
Use automatically composed text to fake the appearance of editorial coverage.

If a protocol approaches us with a paid placement offer, the answer is no, regardless of the figure.

Editorial principles

Three rules guide everything we publish:

Data first. Every claim on a pool, protocol, or chain page is sourced from public on-chain data via DefiLlama. We do not make claims that aren’t backed by that data.
Templated text, not human prose. Overview blocks are composed from the same structured data shown in the table above them - never from external sources, never extrapolated, never invented. The pipeline is constrained to use only the data provided as input, and outputs are validated for length and forbidden phrases before publication. See our methodology for the full pipeline.
Risks are stated explicitly. Every pool page includes a rule-based risk profile (smart-contract risk, impermanent loss, depeg risk where applicable, yield variability). These notes are derived from structured data, not editorial judgment, so they’re consistent across all 19,000 pools.

What this site is not

We are not financial advisors. Nothing on this site constitutes investment advice, a recommendation to buy or sell any token, or an endorsement of any protocol. The yield numbers shown are reported by the underlying protocols, not independently verified, and they change continuously.

DeFi is high-risk. Smart-contract exploits, depeg events, governance attacks, and protocol failures happen regularly. Use this site as one input in your decision-making, alongside the protocol’s own documentation, audit reports, and your own due diligence.

Open questions

There’s a lot we’d like to add but haven’t yet:

Editorial protocol descriptions for the top 50 protocols. Currently we have one (Aave V3) as a proof of concept; expanding this is ongoing work.
Cross-chain comparisons (“USDC lending across all chains, sorted by 30-day mean APY”) at the section level rather than only via filters.
Historical APY for the long tail. We currently have rich history for the top 200 pools; expanding to the long tail depends on solving rate-limiting on third-party APIs.
Multilingual versions. English first; other languages once the English site has proven traction.
