Verify a decision

Every moderation decision on AVOID.NET is anchored to the Solana blockchain. You don't have to trust us — you can verify cryptographically that we committed to a verdict at a specific moment and have not rewritten it.

How verification works

  1. We commit. When a moderator accepts/rejects a submission, we serialize the decision into deterministic UTF-8 bytes (payload_canonical_string), hash it with SHA-256, encode the digest as base58, and write it to Solana inside an SPL Memo v2 transaction.
  2. We store the bytes. The exact bytes we hashed are stored alongside the decision in our database. Anyone can read them and recompute the hash in any language.
  3. You compare three values. Database hash, your independently-recomputed hash, and the hash inside the on-chain memo. If all three match, the decision is authentic and timestamped.
The on-chain memo format is AVOID.NET|v1|h:<b58-sha256>|d:<id>|t:<iso>

Find a signature on any investigation page's decision log, or run python -m src.verify_decision --signature <sig> for a CLI check.

Its two flagship instruments are Dual Investment Pools (DIPs) and Staking Options. DIPs are physically-settled options that give depositors enhanced yield by writing covered calls or cash-secured puts across a menu of strike prices and maturities. Staking Options allow protocols to incentivize liquidity provision by distributing free out-of-the-money call or put options rather than inflationary token rewards, generating potential treasury revenue when options are exercised. The protocol integrates Pyth Network for real-time oracle price feeds and historically used Mango Markets as the underlying exchange for hedging. In 2024, Dual Finance announced a strategic partnership with the Manifest on-chain order book (CKS Systems), enabling creation of call and put options on any listed Solana token through a trustless P2P mechanism. The DUAL governance token, launched March 2, 2023, is used for voting on protocol parameters and represents a claim on a portion of inventory risk and revenues.","heading":"Protocol Overview and Products","severity":"low","sources":[{"credibility":2,"name":"Dual Finance Whitepaper — Medium","type":"official","url":"https://medium.com/@dualfinance/dual-finance-whitepaper-73f90f778c26"},{"credibility":2,"name":"Manifest Brings Options Trading to Solana in Strategic Dual Finance Partnership — Crypto Economy","type":"news_article","url":"https://crypto-economy.com/manifest-brings-options-trading-to-solana-in-strategic-dual-finance-partnership/"},{"credibility":2,"name":"Dual Finance Phase Two Roadmap — Medium","type":"official","url":"https://medium.com/@dualfinance/phase-two-roadmap-d64ec04014cb"},{"credibility":2,"name":"Dual Finance — Pyth Network Interview","type":"news_article","url":"https://www.pyth.network/blog/interview-dual-finance"}]},{"content":"Dual Finance was co-founded by John Kramer and Britt Cyr, both of whom have publicly verifiable real-world identities (status: named). John Kramer holds a Master's degree in Finance from MIT Sloan (2015-2016) and previously served as Head of OTC and Derivatives Trading at GSR Markets, a major digital-asset market maker, as well as trading equity derivatives at Wellington Management and crypto investments at Consolidated Trading. He subsequently moved to CKS Systems as Head of Trading after the Manifest integration. Britt Cyr holds a Master's degree in Computer Science from MIT (2014-2015) and previously held lead developer roles at YouTube, Google, and Facebook. The named, credentialed founding team with verifiable prior employment at established TradFi and FAANG-tier firms represents a positive trust signal relative to many DeFi protocols with anonymous or pseudonymous leadership.

However, no named audit reports from specific auditors (such as OtterSec, Neodyme, Sec3, or Halborn) could be independently confirmed via public audit repositories or the Dual-Finance GitHub organization during this investigation. The GitHub organization (github.com/Dual-Finance) contains 17 repositories including the primary staking-options program written in Rust, which had its most recent release (v0.0.23) in January 2026, indicating ongoing development. The whitepaper (March 2022) contained no mention of specific auditors. The absence of a publicly-linked, named audit report is a moderate risk signal for a protocol that has handled up to $35M in TVL. The protocol is described as non-custodial: users interact directly with on-chain programs and physical settlement occurs on-chain without a centralized intermediary holding funds.","heading":"Security Audits and Smart Contract Risk","severity":"medium","sources":[{"credibility":2,"name":"Dual-Finance GitHub Organization","type":"official","url":"https://github.com/Dual-Finance"},{"credibility":2,"name":"GitHub — Dual-Finance/staking-options","type":"official","url":"https://github.com/Dual-Finance/staking-options"},{"credibility":2,"name":"DUAL Finance on Solana — Solana Compass","type":"research","url":"https://solanacompass.com/projects/dual-finance"},{"credibility":2,"name":"Dual Finance Whitepaper — Medium","type":"official","url":"https://medium.com/@dualfinance/dual-finance-whitepaper-73f90f778c26"}]},{"content":"Dual Finance experienced substantial growth through 2023, with TVL increasing approximately 13,980% year-over-year to approximately $35 million, ranking it 14th among all Solana protocols and 2nd among options protocols at its peak. As of mid-2025, DeFiLlama reports TVL at approximately $443,700, representing a decline of over 98% from peak. The DUAL token reached an all-time high of approximately $0.877 on July 28, 2023, and had declined significantly by 2025, with prices quoted in the range of $0.003-$0.024 depending on the platform queried. Total supply is 146 million DUAL. The token was never sold in a traditional public or private sale; distribution occurred exclusively through Staking Options, with 7.5% of supply airdropped via Community Seed in March 2023 and the founding team retaining no initial token allocation. The Dual DAO raised over $600,000 in stablecoin revenue through option exercise in 2023. The protocol achieved meaningful ecosystem adoption with projects including BONK and Mango DAO deploying Staking Options for treasury management. The sharp TVL decline from 2023 highs to 2025 lows may reflect broader options-market contraction on Solana and competitive pressure rather than any specific protocol failure.","heading":"TVL, Market Activity, and Protocol Health","severity":"medium","sources":[{"credibility":2,"name":"Dual Finance TVL Stats and Charts — DeFiLlama","type":"research","url":"https://defillama.com/protocol/dual-finance"},{"credibility":2,"name":"Dual Finance — A Year in Review 2023 — Medium","type":"official","url":"https://medium.com/@dualfinance/dual-finance-a-year-in-review-856b3853dc21"},{"credibility":2,"name":"Dual Finance price today — CoinMarketCap","type":"research","url":"https://coinmarketcap.com/currencies/dual-finance/"},{"credibility":2,"name":"Token FAQ — Dual Finance GitBook","type":"official","url":"https://dual-finance.gitbook.io/dual-finance-documentation/faq/token"}]},{"content":"The DUAL token employs an unusual distribution mechanism: it is claimed to be the first governance token distributed exclusively through options rather than through a pre-sale, public sale, team allocation, or traditional airdrop. The March 2023 Community Seed Airdrop distributed options (not tokens directly) representing 7.5% of total supply to 872 accounts across five tranches with varying strike prices and expiration dates. Recipients must exercise their options by paying the strike price in stablecoins to the Dual DAO treasury in order to receive DUAL tokens. The founding team held no initial token allocation or options at launch. The intended effect is that token supply expands only when demand exists and the protocol generates treasury revenue from strike price payments. While this model creates positive incentive alignment, the low current trading volume and price depreciation suggest limited ongoing demand. DUAL holders bear potential downside from the protocol's inventory risk positions, as disclosed.","heading":"Tokenomics and Distribution Model","severity":"low","sources":[{"credibility":2,"name":"Token FAQ — Dual Finance GitBook","type":"official","url":"https://dual-finance.gitbook.io/dual-finance-documentation/faq/token"},{"credibility":2,"name":"Dual Finance — A Year in Review 2023 — Medium","type":"official","url":"https://medium.com/@dualfinance/dual-finance-a-year-in-review-856b3853dc21"},{"credibility":2,"name":"DUAL Finance on Solana — Solana Compass","type":"research","url":"https://solanacompass.com/projects/dual-finance"}]},{"content":"No regulatory actions, SEC filings, CFTC enforcement, DOJ indictments, OFAC sanctions, civil lawsuits, or fraud allegations against Dual Finance, its founders, or its associated entities were identified in this investigation.

The protocol historically used Mango Markets as the underlying exchange for delta hedging, a relationship that carried counterparty risk given the October 2022 Mango Markets governance exploit (which affected Mango DAO, not Dual Finance directly). Dual Finance's Phase Two roadmap emphasized migrating toward a more distributed liquidity-provider model to reduce concentration risk. In September 2024, co-founders John Kramer and Britt Cyr participated in the launch of the Manifest on-chain order book through CKS Systems (alongside Maximilian Schneider, founder of Mango Markets), positioning Dual Finance as the options infrastructure layer atop Manifest's CLOB. This integration reportedly increased Manifest's TVL by 343%.

The protocol's Medium blog does not appear to have published updates beyond 2023 year-in-review content based on available search results. Social media activity on the official X account (@DualFinance) appears reduced.
