Arbitrage & Trading Opportunities DeFi Screener
"Platform" / "Screener" — the website, application, boards, and screeners operated by us, together with related APIs, background workers, and alerting services.
"Content" — all data, analytics, computed redemption spreads, fair-value estimates, annualized APY figures, rankings, redemption-period readings, and any other output displayed on the Platform.
"Data Sources" — third-party blockchain RPC providers, DEX price aggregators, and the public smart contracts of the protocols we track (including but not limited to Ethena, Sky, Curve, Frax, Inverse, and others).
"Protocols" — the independent third-party DeFi projects whose on-chain data the Platform reads. We are not affiliated with them.
"Subscription" — time-limited access to the Platform (a free trial or a paid term).
"License Key" — the personal credential issued to you to access the Platform for your Subscription term.
The Screener is an information and data-visualization tool. It reads publicly available on-chain data through RPC providers and ERC-4626 contract interfaces, retrieves indicative price quotes from DEX aggregators, and presents computed redemption spreads and cross-chain opportunities expressed as an annualized APY, denominated in the underlying stablecoin.
The Platform is non-custodial. It never holds, controls, or has access to your funds, wallets, private keys, or seed phrases, and it never transacts on your behalf.
The Platform does not:
All spreads, APY figures, fair-value estimates, rankings, and any output labelled "opportunity", "spread", or similar are mathematical models applied to public market and on-chain data. They describe model outputs only, for informational and educational purposes, and are not instructions, recommendations, or solicitations to transact.
We are not a registered investment adviser, broker-dealer, or financial institution, and the operator is not a licensed financial adviser. Nothing on the Platform constitutes financial, investment, trading, legal, tax, or any other regulated advice.
Any Content generated by the Platform:
You should consult a qualified, licensed professional before making any financial decision. You make all decisions yourself, at your own risk.
By using the Platform you represent and warrant that you:
The Platform is not directed at, and may not be used by, any person located in any jurisdiction where access to DeFi/digital-asset information services, or to the underlying protocols, is prohibited or restricted. Depending on your location, access to certain stablecoin or DeFi protocols may be restricted under applicable law; you represent that your use is permitted where you are. We may, at our discretion, geo-block, restrict, or refuse service to any User.
Your License Key is personal, single-user, non-transferable, and confidential. You must not share, sublicense, publish, or resell it. We may suspend or revoke access where a key is shared, abused, or used in breach of these Terms. The Platform enforces a concurrent-session limit per key; exceeding it may evict older sessions.
Trial. The free trial grants full access for a fixed period (currently 5 days), one trial per email address, with no payment required. Trials are provided at our discretion and may be modified or withdrawn at any time.
Paid access. Paid access is purchased by a one-time, on-chain payment in stablecoins (USDC / USDT) for a fixed term (currently 12 months). There is no recurring billing and no automatic renewal. We do not store card details and never initiate charges; you send the payment yourself from your own wallet. Your License Key is issued after the payment reaches the required number of on-chain confirmations, and is emailed to the address you provide.
Pricing & amount. The price and the exact amount payable are shown at checkout and are fixed by us at the moment an intent is created. You are responsible for sending the exact amount, on the network you selected, within the displayed payment window. Payments of the wrong amount, on the wrong network, or after the window closes may not be credited automatically and may require manual review.
Refunds. On-chain cryptocurrency payments are final and irreversible by their nature. All sales are final and non-refundable, including for periods of service interruption, except where a refund is required by applicable mandatory consumer-protection law. Network fees (gas), slippage, and any losses incurred while sending payment are your responsibility and are not reimbursable.
You agree not to:
Content is derived in real time from public blockchains via third-party RPC providers, from DEX price aggregators, and from the public smart contracts of independent Protocols. We are not affiliated with, endorsed by, or acting on behalf of any Protocol, RPC provider, or aggregator unless expressly stated. Your interaction with any Protocol is governed by that Protocol's own rules and smart contracts, which may change, pause, or fail at any time.
We do not control, verify, or guarantee the accuracy, completeness, timeliness, or reliability of any data. On-chain readings reflect contract state only at the moment they are read and may be stale by the time you act. DEX aggregator quotes are indicative, are modelled at a reference trade size, and may differ materially from the price you actually receive. Data may be delayed, incorrect, incomplete, or unavailable due to provider outages, rate limits, reorgs, feed errors, or transmission failures.
All data is provided "as is" and "as available", with no warranty of fitness for any purpose.
The Screener compares a market buy price against an on-chain fair redemption value and expresses the difference as an annualized APY. A displayed spread is a point-in-time theoretical figure and may not be realizable. Actual results can differ materially, or turn negative, because of factors the model does not and cannot fully capture, including:
convertToAssets / previewRedeem;APY figures are annualized projections extrapolated from a momentary spread; they are not guaranteed, recurring, or realizable returns. Because all figures are denominated in the underlying stablecoin and rely on no USD price oracle, they do not represent a US-dollar return and do not reflect any change in the stablecoin's own value.
Interacting with DeFi Protocols carries substantial and sometimes total risk of loss. You acknowledge that:
The Screener is not a party to any transaction you enter with any Protocol and has no ability to reverse, recover, or intervene in it. We bear no responsibility whatsoever for any losses, damages, or missed opportunities arising from your use of the Platform or from decisions based, in whole or in part, on Content obtained from it.
You further acknowledge that:
To the maximum extent permitted by law, the Platform and all Content are provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted or error-free operation.
To the maximum extent permitted by applicable law, we, our operator, developers, and affiliates shall not be liable for any:
This limitation applies regardless of the legal theory and even if we were advised of the possibility of such damages.
Aggregate cap. To the extent liability cannot be excluded, our total aggregate liability arising out of or relating to the Platform shall not exceed the greater of (a) the total fees you paid to us in the 12 months preceding the event giving rise to the claim, or (b) USD 50. Some jurisdictions do not allow certain exclusions or limitations, so the above may not apply to you in full; nothing in these Terms limits liability that cannot be limited by law.
You agree to indemnify, defend, and hold harmless us, our operator, developers, and affiliates from and against any claims, losses, liabilities, damages, and expenses (including reasonable legal fees) arising from your use of the Platform, your breach of these Terms, your transactions with any Protocol, or your violation of any law or third-party right.
All source code, algorithms, analytical models, interface designs, and proprietary methods embodied in the Platform are our exclusive intellectual property. Reverse engineering, decompilation, redistribution, or reproduction of any part is strictly prohibited.
Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Platform for your personal or internal purposes during your active Subscription. On-chain data belongs to no one; this grant covers our presentation, computation, and interface, not the underlying public data.
Statements made by community members, social-media accounts (including our own posts on X), or any promotional channel are informational only and do not constitute advice, warranties, or representations. No one is authorized to give financial advice on our behalf or to make any representation beyond these Terms. Forward-looking, illustrative, or promotional statements are not guarantees of any outcome. Where any promotion is conducted by or for us, any required disclosure of the relationship will be made.
The Platform is provided on a best-effort basis and runs as a single-instance service. We do not guarantee uninterrupted or error-free operation, and the Platform (or any board, screener, or module) may be suspended, modified, or discontinued at any time, with or without notice, due to maintenance, Data Source changes, infrastructure issues, or any other reason. Fees are for access as available during the term.
We may suspend or terminate your access immediately for breach of these Terms or where required by law. You may stop using the Platform at any time. Sections that by their nature should survive termination (including Sections 8–15, 18, and 21) will survive.
We collect only what is needed to run the service. This includes: your email address (to deliver your License Key and, if you opt in, alerts); your License Key and session data; and technical identifiers used for security and rate-limiting — your IP address, user-agent, and a session cookie, retained for no more than 30 days. If you enable alerts, we also store your Telegram chat ID. On-chain payment details are public by nature of the blockchain.
We use no third-party analytics or advertising trackers. We do not sell your data. Cookies we set are strictly functional (session and security). Where applicable, you have rights under the GDPR, UK GDPR, CCPA, and similar laws, including access, correction, and deletion; to exercise them, or to request deletion of your stored data, contact us at the address in Section 23.
Where the alerts feature is offered and you choose to enable it, you provide a Telegram chat ID (and, if required, a bot token) so that we can deliver threshold alerts to you server-side, including when your browser is closed. Any such credential is stored linked to your License Key and is never published or returned in plaintext in logs or responses. You are responsible for safeguarding your own Telegram credentials and for compliance with Telegram's terms. You can revoke a bot token at any time via Telegram's @BotFather, and you can request deletion of your stored credentials at any time.
We may modify these Terms at any time. Changes will be posted on this page with an updated effective date. Continued use after changes constitutes acceptance of the revised Terms.
These Terms are governed by applicable law, without regard to conflict-of-laws principles. Any dispute arising out of or relating to the Platform or these Terms shall be subject to binding arbitration or to the exclusive jurisdiction of the competent courts of the applicable jurisdiction. Nothing in this Section deprives a consumer of the mandatory protections of the law of their country of residence (e.g. EU/UK consumers).
