Frequently Asked Questions

Add2Coin is a research-led platform for transparent advertising attribution and on-chain reward distribution. It is operated by AI Administrator Limited, a company registered in England and Wales (Companies House 16262184), and uses the Polygon blockchain to record reward allocations. The underlying mechanism is the subject of UK patent application GB2606991.4, filed 28 March 2026.

In digital advertising, the value generated when a person sees an advertisement is typically opaque: it passes through several intermediaries, with no party in the chain able to independently verify what fraction of the original spend reaches the publisher whose page hosted the impression, and the visitor whose attention was the underlying commodity has no record of the transaction at all. Add2Coin is a parallel attribution and settlement layer that records each impression with cryptographic verifiability and distributes a small unit of value to every party in the attribution chain in proportion to their contribution.

Yes. There is no fee to register, no subscription, and no requirement to purchase A2C tokens. Website operators install the script at no cost. Visitors who choose to register an account and become eligible to receive rewards do so without paying anything. The platform recovers its operating costs through a share of the per-impression allocation (35%), not through user fees.

For website operators, the only technical requirement is the ability to add a single line of HTML to the page template — typically a script tag immediately before the closing body tag. For WordPress and PrestaShop sites, plugins handle this automatically. For static sites, content management systems, and custom-built sites, manual installation requires the same level of technical knowledge as installing Google Analytics or any other JavaScript-based service.

A2C is an ERC-20 utility token deployed on the Polygon blockchain, used as the unit of account for reward distributions within the Add2Coin platform. The contract is deployed at 0x999ca1479AF9d38933F8EbF7Bb1d2470aFcc337C and has a hard maximum supply of one billion tokens. A2C is not a security, not a financial instrument, and not e-money. It is a utility token within a specific platform context. It is freely tradeable on the Uniswap V3 decentralised exchange on Polygon.

Add2Coin is operated by AI Administrator Limited, a private limited company registered in England and Wales. Its registered office, correspondence address, and Companies House filings are public. The company is registered with the United Kingdom Information Commissioner's Office under registration A1126359 for data protection compliance. The platform is subject to United Kingdom and European Union data protection law.

The platform uses the W3C Page Visibility API, a standard browser interface that reports whether a tab is currently in the foreground and whether the page is currently rendered. The script measures cumulative active visibility time, pausing when the tab is hidden and resuming when it returns to view. Once the cumulative visible time crosses a configurable threshold, the impression is considered eligible for attribution. This produces a measurement that cannot be inflated by background tabs, hidden iframes, or autoplay scripts.

When an impression occurs on a participating website, the system identifies the chain of parties whose participation made the impression possible. The chain consists of: the website operator on whose site the impression occurred; the operator's recruiter, if any (Level 1); that recruiter's recruiter (Level 2); and one further recruiter (Level 3). Each party in the chain receives a small allocation of A2C tokens proportional to their position. The chain is resolved from a relational database that records the recruitment relationships between accounts.

If a level of the chain is unfilled — for example, if a website operator was not recruited by anyone, so there is no Level 1 referrer — the corresponding tokens are simply not minted. They are not redirected to a treasury, not redistributed to filled levels, and not deferred for future distribution. They are not created at all. This deflationary non-allocation property means the actual circulating supply grows more slowly than the maximum it would under fully-populated chains, in proportion to the network's structural incompleteness. This is one of the novel claims in the underlying patent application.

Allocations are recorded immediately in a relational database when an impression occurs. They are not yet on the blockchain at this stage. Once per day, a scheduled process aggregates all unsettled allocations from the previous twenty-four hours and submits them to the Polygon blockchain in a single batched transaction. The transaction calls a batchMint function on the A2C token contract, which mints the calculated quantities to the recipient wallet addresses in one operation. Batching reduces per-impression on-chain cost by approximately three orders of magnitude relative to per-event settlement.

The base emission rate is reduced by fifty per cent each time the cumulative count of verified impressions across the entire network reaches a multiple of fifty million. The halving is automatic, on-chain-verifiable, and triggered by activity rather than time. After the first halving, the base rate becomes 0.50 A2C per impression. After the second, 0.25. The schedule is asymptotic: the cumulative supply approaches but cannot exceed the one-billion cap.

Seventy per cent of advertising revenue received by the platform is routed automatically through the RevenueRouter smart contract to purchase A2C from the Uniswap V3 liquidity pool. A configurable proportion of purchased tokens is permanently destroyed. This produces ongoing buy-side demand and a continuous, observable reduction in circulating supply. The remaining thirty per cent is split between the Treasury wallet (20%) for ongoing platform development and the Operations wallet (10%) for daily operational costs.

There are three roles: website operators (who embed earn.js on their pages), visitors (whose attention triggers attribution events), and recruiters (who introduce other operators to the platform). The same individual or entity can occupy any combination of these roles. A single registered user is both a visitor on other people's sites and an operator of their own site, and can also be a recruiter to anyone who registered through their referral link.

When a website operator registers via someone else's referral link, the referring party becomes the new operator's Level 1 recruiter, recorded in the attribution graph. From that point onward, every qualifying impression on the new operator's site credits the recruiter at the Level 1 rate. If the recruited operator goes on to recruit a third party, the original recruiter is credited at the Level 2 rate for those further impressions. The chain extends to Level 3.

No. Referral allocations are additive, not subtractive. The website operator's share of each impression is unaffected by the presence or absence of recruiters in their attribution chain. The recruiter's share is created in addition to the operator's share, not deducted from it. This means the operator has no economic disincentive to be recruited by someone, and the recruiter has no zero-sum relationship with the operator they recruited.

Visitors who do not register an account can still trigger attribution events for the operators of pages they visit, but no token is allocated to the visitor themselves because there is no account to credit. Visitors who register and provide a Polygon wallet address become eligible to receive their share of subsequent qualifying impressions. Registration is free and does not require purchase of any token.

A user can request a withdrawal once their confirmed balance reaches the minimum threshold set in the dashboard. Standard withdrawals are processed in the daily settlement batch at no charge. Express withdrawals are processed hourly and carry a fee equal to the greater of 5 A2C or 2% of the withdrawal amount. The fee covers the on-chain transaction cost.

Withdrawn A2C tokens are sent to the user's nominated Polygon wallet address. Users need a Polygon-compatible wallet (such as MetaMask) with their wallet address registered in their Add2Coin account. From that wallet, the tokens can be held, transferred to another address, or traded on the Uniswap V3 decentralised exchange.

Yes. To comply with United Kingdom Money Laundering Regulations 2017, identity verification is required before the first withdrawal. Verification is a one-time process handled via a third-party Know Your Customer (KYC) provider. Identity documents are not stored on the Add2Coin platform itself; the platform records only the verification status returned by the KYC provider.

Standard withdrawals processed in the daily settlement batch are free. Express withdrawals processed hourly carry a fee of the greater of 5 A2C or 2% of the withdrawal amount. The fee covers the on-chain gas cost of the transfer transaction on the Polygon network. There are no other fees.

A2C is a utility token. Its value is determined by open-market trading on the Uniswap V3 decentralised exchange and is not guaranteed by the platform. The platform's monetary policy is intended to keep supply growth conservative through the deflationary non-allocation rule, the activity-triggered halving schedule, and the automatic buyback-and-burn mechanism. Whether these mechanisms produce a particular price outcome is a function of market activity, not platform commitment.

The hard maximum supply is 1,000,000,000 A2C, enforced by the smart contract: any mint call that would exceed this cap reverts. The cap is a ceiling, not a target. The actual circulating supply grows more slowly than the cap due to deflationary non-allocation and the halving schedule, and the cap is mathematically asymptotic — it cannot be reached.

A2C is a utility token within a specific software platform, used to record and reward verified attention to advertising content. It is not offered as a security, financial instrument, or investment. The platform makes no representation about future price, no commitment to redeem A2C for fiat currency, and no promise of returns. Acquisition of A2C through trading is a market activity outside the platform's control. Nothing on this site constitutes financial advice. Users in jurisdictions where the holding or trading of cryptocurrency is restricted should consult their local regulations before participating.

The platform receives 35% of each per-impression allocation, denominated in A2C. The platform also receives the cash revenue paid by advertising networks for the impressions served on participating sites. Of that cash revenue, 70% is used to buy A2C from the open market (the buyback), 20% is allocated to the Treasury for ongoing platform development, and 10% is allocated to the Operations wallet for daily operational expenses. All flows are publicly verifiable on the Polygon blockchain.

The earn.js script collects: the operator's referral code (from the script tag's URL parameter); the host page's domain (from window.location); the device type (from viewport width); a pseudonymous identifier stored in browser local storage; and the cumulative active visible time of the page measured via the Page Visibility API. It does not collect: page contents, form inputs, scroll patterns, mouse movements, browsing history, IP addresses (these are seen by the server but not stored long-term against the visitor), or any personally identifying information.

Yes. The platform operates under the General Data Protection Regulation and the United Kingdom Data Protection Act 2018. The lawful basis for processing visitor data is legitimate interest in operating the attribution mechanism, with consent collected for any processing that goes beyond that. The full lawful-basis statements, retention periods, and rights afforded to data subjects are documented in the privacy policy.

No. The pseudonymous identifier stored in your browser is a randomly generated string with no link to your real-world identity. It is not linkable to your name, email, or other identifying information unless you voluntarily register an account. If you do register, you have provided that link yourself.

The full privacy policy, including the categories of data processed, the retention periods, the legal bases for processing, the recipients of data, and the rights available to data subjects (access, rectification, erasure, portability, objection, restriction), is published at add2coin.com/privacy.

The script is approximately 12 kilobytes after compression, served over HTTPS, and has been designed with the principle that it should never affect the host site's rendering or user experience. It does not block page rendering. It does not modify other elements on the page. It does not set third-party cookies. The source code is loaded from add2coin.com and is verifiable. Many publishers run security audits on third-party scripts before deployment, and we welcome and assist with such audits.

No. The script is restricted by browser sandboxing to operations on the page on which it loads. It cannot read content from other tabs, cannot execute network requests outside its declared endpoints, and cannot access cookies belonging to other origins. It also cannot inject content into the host page beyond a small ad container that is clearly identifiable.

All contracts are deployed on Polygon Mainnet (Chain ID 137), an Ethereum-compatible Layer 2 network. The contracts are publicly verified on Polygonscan: A2CToken at 0x999ca1479AF9d38933F8EbF7Bb1d2470aFcc337C; RevenueRouter at 0xe3010c69fcdba469d7aadce82edcff090ebb378b; TreasuryWallet at 0x22E4C1E996f9c9180492c8424067671a35F376DD; OperationsKeeper at 0x5Ad3fC0cf7EDeaBE067ABd0A0bB36e09efb6F479.

The engagement criterion based on the Page Visibility API filters out hidden, background, and minimised tab activity. Server-side validation cross-references impression events against IP reputation, timing distribution, and behavioural pattern signals; events that fail validation are flagged for review. The KYC requirement before withdrawals provides an additional barrier against systematic abuse, since obtaining a verified identity is non-trivial. Fraud prevention is an ongoing function rather than a fixed system; the platform refines its filters continuously.

United Kingdom patent application GB2606991.4 was filed on 28 March 2026. It contains twelve claims covering: the script-tag delivery model that enables zero-installation participation; multi-level attribution chain resolution; the deflationary non-allocation rule; activity-triggered halving; visibility-based engagement verification; deferred batch settlement to a distributed ledger; server-side cryptographic signing of settlement instructions; revenue-driven buyback-and-burn; and the integration of these elements into a single coherent system.

No. The application has been filed and a priority date secured, but the patent has not yet been granted. Patents typically take two to four years from filing to grant, and there is no certainty that any given application will be granted as filed. The current status is "patent pending", which is the legally correct way to describe an application that has been filed but has not yet completed examination.

A pending application secures a priority date — the date from which novelty is assessed. Anyone who files a comparable application after 28 March 2026 cannot claim priority over Add2Coin. A pending application is also informative to third parties: a party who implements a similar system after the publication date, with knowledge of the application, may be liable for damages calculated from the date of implementation if the patent is subsequently granted.

A Patent Cooperation Treaty (PCT) international application is scheduled for filing on or before 28 March 2027. The PCT is the standard mechanism for converting a national priority application into international protection. National-phase entries are planned for the United Kingdom, the European Patent Office, and the United States. Other jurisdictions (for example, Canada, Australia, Singapore, Japan) may be added if the platform's commercial development justifies the cost.

The patent application is held in the personal name of the named inventor, with an exclusive licence granted to AI Administrator Limited for commercial exploitation. This structure is common for early-stage inventor-led ventures and does not affect the platform's ability to operate the mechanism. The named inventor is recorded in the public UKIPO patent register; the platform does not republish that information beyond what UKIPO publishes.

Brave Browser uses Basic Attention Token (BAT) to reward viewers of ads. To participate, users install the Brave browser. Add2Coin requires no installation: it operates inside any standard web browser via a script tag on participating sites. Additionally, Brave rewards only the individual viewer; Add2Coin rewards a multi-level chain (operator, viewer, and up to three recruiters). Brave's emission schedule is time-based; Add2Coin's is activity-triggered. Brave does not implement deflationary non-allocation. These distinctions are reflected in multiple claims in the pending Add2Coin patent.

The platform was built to test a specific technical proposition: that a transparent, multi-stakeholder advertising attribution layer could be implemented as a thin overlay on existing web infrastructure, requiring no installation by end users and no modification to host sites beyond a single script tag. The proposition is the substance of the pending patent application. Operating the platform as a live system, rather than only describing it in a paper, allows the proposition to be tested against real-world conditions and refined accordingly.

Both. Add2Coin is operated as a commercial platform with a sustainable business model based on a share of advertising revenue and the platform's allocation of A2C. It is also a research platform: the operation of the mechanism in production produces data on engagement, attribution, and economic flow that informs the wider technical literature on web monetisation. The platform is open to academic researchers who wish to study its operation under appropriate research-collaboration terms.
