Bostoncoin (BOS) is a Polygon-based token associated with Boston Trading Co.’s flagship diversified cryptocurrency investment fund.
Rather than functioning like a conventional standalone cryptocurrency, BOS represents participation in a professionally managed portfolio containing multiple digital assets and, depending on the portfolio strategy, other technology-related investments.
Boston Trading Co says the underlying Bostoncoin fund was established in January 2016. BOS originally existed on Ethereum and later moved to Polygon, where the current token has been used since 2020.
That structure makes Bostoncoin quite different from cryptocurrencies such as Bitcoin or Ethereum. BOS does not secure its own blockchain, does not have miners or validators and is not primarily designed as a decentralized payment currency.
It is better understood as a tokenized investment product connected to a managed crypto portfolio.

What Is Bostoncoin?#
Bostoncoin is the flagship investment product operated by Boston Trading Co.
The concept is to provide diversified exposure to cryptocurrency through a portfolio rather than requiring an investor to independently select, buy and manage numerous individual crypto assets.
Boston Trading Co manages the underlying portfolio and publishes periodic information about its composition and performance.
BOS is the token associated with that fund.
This means Bostoncoin should not be confused with an ordinary cryptocurrency whose market value is determined solely by decentralized exchange trading or blockchain demand.
Its structure is linked to an underlying managed investment portfolio.
How Does the Bostoncoin Fund Work?#
A diversified fund spreads capital across multiple investments instead of concentrating it in a single asset.
For Bostoncoin, the portfolio has historically included a selection of cryptocurrencies alongside technology-related investments.
The exact holdings can change as Boston Trading Co adjusts the portfolio.
This is fundamentally different from holding Bitcoin directly.
A Bitcoin holder owns one particular crypto asset. A Bostoncoin participant instead receives exposure to a portfolio whose composition is determined by the fund manager.
Diversification can reduce dependence on the performance of any single holding, but it does not eliminate investment risk.
If the overall cryptocurrency market declines, individual holdings perform poorly or portfolio-management decisions are unsuccessful, the value of the fund can still fall.
What Is BOS?#
BOS is the token associated with Bostoncoin.
The current version operates on the Polygon network.
Boston Trading Co identifies the current BOS contract as:
0xC91B7d12a30Dd073007A991BA3a7EC11243D253c
The token uses 18 decimals and can be displayed in EVM-compatible wallets such as MetaMask.
Because BOS exists on Polygon, users need the correct network and token contract when adding it to a self-custody wallet.
A token simply having the name “Bostoncoin” or ticker “BOS” is not sufficient verification. Contract addresses should always be checked against an official source.
Bostoncoin Originally Used Ethereum#
Bostoncoin has existed across more than one blockchain during its history.
Boston Trading Co’s current wallet documentation identifies two BOS contracts:
Current Polygon BOS
0xC91B7d12a30Dd073007A991BA3a7EC11243D253c
Historical Ethereum BOS
0x1daFDe927870f6eECE7d5d32b958b4A2Fc89953B
The company describes the Ethereum version as applying to BOS held from 2016–2020, while the Polygon token has been used since 2020.
That distinction matters for anyone researching historical transactions or older Bostoncoin wallets.
An old Ethereum BOS balance should not automatically be treated as the same contract as the current Polygon token.
Why Did Bostoncoin Move to Polygon?#
Polygon is an EVM-compatible blockchain network designed to support token transfers and smart-contract applications with generally lower transaction costs than Ethereum mainnet.
For a token such as BOS, Polygon allows holders to use familiar Ethereum-style wallet infrastructure without relying on Ethereum mainnet for every token transfer.
Boston Trading Co’s documentation currently instructs BOS holders to add the Polygon contract to MetaMask.
The migration does not mean that Bostoncoin operates its own blockchain.
Polygon is the underlying blockchain. BOS is a token running on it.
Bostoncoin’s History#
Boston Trading Co currently dates the Bostoncoin fund to January 2016.
The project’s history is somewhat more complicated when the investment fund and BOS token are considered separately.
A surviving Boston Coin whitepaper published in 2018 documented plans for an ICO and described BOS as an Ethereum-compatible ERC-20 token. That document proposed a 20 million BOS supply and outlined a diversified portfolio model.
Current Boston Trading Co material, meanwhile, describes the fund itself as operating since January 2016 and identifies an Ethereum BOS contract for holdings from 2016 through 2020.
The safest way to understand this chronology is to distinguish the two concepts:
Bostoncoin fund — described by Boston Trading Co as established in January 2016.
Token structure — documented through later Ethereum issuance material and subsequently migrated to Polygon.
This avoids treating every historical milestone as though it represents the same event.
What Does Bostoncoin Invest In?#
Bostoncoin is described as a diversified crypto-focused portfolio rather than a single-asset fund.
The composition can change over time.
Boston Trading Co’s historical and current updates have referenced holdings across cryptocurrencies and technology-related assets.
Because the portfolio is actively managed, an asset appearing in an old Bostoncoin update should not be assumed to remain in the fund today.
Current holdings should be checked through Boston Trading Co’s latest portfolio or monthly reporting.
This is particularly important for an actively managed fund because allocations can change substantially as market conditions and management decisions change.
What Is NAV?#
One of the most useful concepts for understanding Bostoncoin is net asset value, or NAV.
For an investment fund, NAV represents the value of the underlying assets after accounting for liabilities.
A simplified calculation is:
NAV = Assets − Liabilities
The NAV per unit then divides that value by the relevant number of fund units or tokens.
Boston Trading Co has historically published NAV figures alongside BOS pricing in its monthly updates.
NAV and the displayed BOS price should not automatically be considered identical concepts.
A token or fund unit may be priced according to additional rules, fees or market conditions.
Researchers should therefore look at the methodology accompanying the latest published figures rather than assuming that a quoted BOS price directly equals the value of the portfolio assets.
Is Bostoncoin an Index Fund?#
Boston Trading Co currently refers to BOS as its flagship diversified quasi-index crypto fund.
“Quasi-index” is an important distinction.
A conventional index fund normally follows a predefined benchmark according to published weighting and rebalancing rules.
Bostoncoin is actively managed.
Its portfolio managers research and select assets rather than merely replicating a fixed cryptocurrency index.
It is therefore more accurate to describe BOS as a diversified managed crypto fund rather than a passive crypto index.
Who Manages Bostoncoin?#
Bostoncoin is operated by Boston Trading Co.
The company’s current website identifies BostonTrading & Education Inc LLC in the United States and describes its team as having backgrounds in traditional investment markets as well as cryptocurrency.
The operator, rather than a decentralized DAO or blockchain protocol, determines the fund’s portfolio strategy.
This creates a different trust model from holding a decentralized cryptocurrency directly.
Bostoncoin investors are exposed not only to the assets in the portfolio but also to operational, custody, management and counterparty risks associated with the investment structure.
Can Anyone Buy Bostoncoin?#
Bostoncoin should not be treated like an unrestricted meme token available to anyone through a decentralized exchange.
Boston Trading Co currently states that its managed funds are available only to qualifying investors depending on jurisdiction.
Its investment page references categories including:
- sophisticated investors in the United States
- wholesale investors in Australia
- accredited investors in Singapore
- equivalent eligible investors in other jurisdictions
Boston Trading Co also states that investment clients are subject to KYC and AML checks.
Eligibility rules can differ significantly by country and can change over time.
Anyone considering the product should therefore check the current terms directly with Boston Trading Co rather than relying on an older description of who may participate.
What Is the Minimum Investment?#
Boston Trading Co currently advertises a US$10,000 starting investment, with smaller subsequent additions available.
That figure is a current company term rather than an inherent technical property of BOS.
Minimums, fees and eligibility requirements can change.
For that reason, they should always be verified against the current Boston Trading Co investment documentation before making a decision.
What Fees Does Bostoncoin Charge?#
Boston Trading Co’s current website says management fees may range from approximately 1% to 3% per year, depending on the selected fund.
Historical Bostoncoin documentation contains different fee structures.
For example, the original 2018 whitepaper outlined estimated management and other expenses that reflected the proposed structure at that time.
Those historical figures should not be treated as today’s fee schedule.
The current investment agreement and disclosure documents are the appropriate sources for determining applicable fees.
Is Bostoncoin the Same as Holding Cryptocurrency Directly?#
No.
Owning BOS and directly owning the cryptocurrencies inside the Bostoncoin portfolio are structurally different.
With direct ownership, a user controls a particular cryptocurrency in their own wallet.
With Bostoncoin, the investment is linked to a managed portfolio whose underlying assets are selected and administered by Boston Trading Co.
That introduces several additional considerations:
- fund-management risk
- custody arrangements
- fees
- investor eligibility
- redemption processes
- portfolio-management decisions
- legal and regulatory structure
At the same time, diversification means performance is not entirely dependent on one underlying cryptocurrency.
Neither structure is inherently risk-free.
Can BOS Be Held in MetaMask?#
Yes.
Boston Trading Co provides instructions for adding the current Polygon BOS token to MetaMask.
The official contract is:
0xC91B7d12a30Dd073007A991BA3a7EC11243D253c
MetaMask should be configured for the Polygon network before adding the current token.
Boston Trading Co also warns users to protect their recovery phrase.
A recovery phrase provides control over a wallet. Anyone who obtains it can potentially control the assets associated with that wallet.
No legitimate service should require users to disclose their MetaMask seed phrase simply to receive BOS.
How Is Bostoncoin Performance Reported?#
Boston Trading Co publishes regular market and fund updates.
These reports can contain:
- BOS pricing
- portfolio performance
- individual asset performance
- market commentary
- portfolio changes
For example, the company’s July 2026 report published a Bostoncoin price of US$47.69 as of July 31, 2026.
That figure is a dated fund report, not a permanent price.
Current values should always be checked against Boston Trading Co’s latest reporting, since BOS pricing and portfolio performance change over time.
Past performance also does not determine future results.
Does BOS Trade Like a Normal Cryptocurrency?#
Not necessarily.
The presence of a blockchain token does not automatically mean that it has deep public exchange liquidity or price discovery comparable with major cryptocurrencies.
Boston Trading Co’s current application presents BOS as its live Polygon-based fund token and provides wallet integration.
Prospective users should separately verify:
- where BOS can currently be acquired
- whether transfers are restricted
- available liquidity
- redemption procedures
- applicable investor requirements
- how the displayed price is calculated
A quoted fund price and a freely traded decentralized-market price are not necessarily the same thing.
Is Bostoncoin Regulated?#
Regulatory status should be treated carefully.
Boston Trading Co’s current investment page states that its funds are limited to qualifying investor categories and subject to KYC/AML requirements. It also states that license applications are pending in several jurisdictions.
Those statements should not be converted into a broader claim that Bostoncoin is “regulated” everywhere it is available.
Investment-product regulation is jurisdiction-specific.
Users should consult the latest official terms and, where necessary, an appropriately qualified adviser regarding their own jurisdiction.
Is Bostoncoin Still Active?#
Yes.
Chainquiry currently classifies Bostoncoin as Live.
Boston Trading Co continues to operate its website, publishes 2026 monthly fund updates, maintains a live token application and identifies Bostoncoin as its flagship diversified crypto fund.
The company’s August 2026 market update included current Bostoncoin reporting, providing recent evidence that the product continues to be maintained.
What Should You Verify Before Using Bostoncoin?#
Bostoncoin combines blockchain infrastructure with a managed investment product, so research should cover both sides.
Verify:
- the current Polygon BOS contract
- the latest portfolio information
- current NAV and BOS pricing methodology
- applicable management fees
- minimum investment requirements
- investor eligibility in your jurisdiction
- redemption or withdrawal procedures
- custody arrangements
- KYC/AML requirements
- current legal terms
Do not rely solely on historical return figures or promotional comparisons with Bitcoin.
An investment fund can gain or lose value, and diversification cannot guarantee positive returns.
The Bottom Line#
Bostoncoin (BOS) is a tokenized investment product associated with Boston Trading Co’s diversified cryptocurrency fund.
The fund traces its history to 2016, while BOS has evolved technically over time from an Ethereum-based token to the current Polygon implementation used since 2020.
Its current Polygon contract is:
0xC91B7d12a30Dd073007A991BA3a7EC11243D253c
Unlike Bitcoin or a standalone Layer 1 cryptocurrency, BOS does not operate its own consensus network.
Its purpose is connected to a professionally managed portfolio.
That means researching Bostoncoin requires examining more than its token contract. Portfolio composition, NAV methodology, management fees, eligibility requirements, custody arrangements and current legal terms are all relevant to understanding how the product works.
