Neptune Cash (NPT)

Neptune Cash ranks #268 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #1680: 1412 of the 1679 assets ahead of it are not native coins but tokens or claims. A token is issued on a host blockchain rather than running its own; a claim stands for an asset already counted. Of the 2743 non-native assets CoinSpectrum lists above it by market cap, about 80% are tokens, 16% are claims on other assets and 4% are memecoins.

Grade pending. Fewer than six of Neptune Cash's nine network-security points are measured yet. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

Premine (allocated at launch)9.37.42% of today's supply allocated at launch to founders, a company, a foundation or investors. A genesis premine of 831,488 NPT (1.98% of the 42M cap) was sold to investors. Against it, ~11.21M NPT is issued today: the August 2025 genesis (3,559,168 NPT = premine + 21,310 x 128 NPT redistributed from the first chain) plus 59,776 blocks x 128 NPT. source
Fundraising9.3Sold by its issuer or insiders: 7.42% of supply was theirs to sell, 7.42% sold so far. The project says the premine was distributed to investors in its initial funding round to bootstrap development; 831,488 / ~11.21M. A premine of 831,488 NPT (1.98% of the cap) was sold to investors in an initial funding round, run by a founding company that says it will dissolve after launch. The amount raised and the investors are not published. source
Developer share (after launch)10No developer share: every new coin goes to the miners or validators who produce blocks. The 128 NPT subsidy goes to the block composer and the proof-of-work guesser (both block producers); the consensus code has no developer or foundation share. Skipped subsidies from the first chain went to a claims fund for redeeming old balances, not to the team. source
Privacy8section average
Privacy (5 checks)84 of 5 passed source
Protocol level privacy (Keys not tied to an identity · Whitepaper §10)✓UTXOs are locked by lock scripts from keys anyone generates; no identity rule.
UTXO ledger (A new key for each payment · Whitepaper §2, §9)✓
Network privacy (Origin hidden by default)✗neptune-core v0.19.3: no Dandelion or built-in Tor.
Hidden amounts (Amounts confidential)✓UTXO amounts are committed and proven with Triton VM zk-STARKs (only pre-HardforkBeta UTXOs must be lustrated when spent).
Hidden parties (Sender and receiver hidden)✓Mutator sets make spent inputs unlinkable to their outputs, and receivers get one-time UTXO notifications.
Programmability (tokens, contracts, 5 checks)1.41 of 7 points, 2 not yet researched source
Token issuance0No token issuance on the chain itself
Smart contracts (Scripting for spending conditions)1UTXOs are locked by Triton VM lock scripts proven in zero knowledge and used for spending conditions only; consensus recognises only the native-currency and time-lock type scripts.
Multisig and time locks (Without a third party)–The TimeLock type script releases coins at a set date, but no m-of-n lock script is implemented or documented in neptune-core, so multisig could not be established.
Atomic swaps (With other chains)–The standard lock script is a hash lock on a spending key, and no HTLC or adaptor-signature swap is implemented, so swaps could not be established.
Native exchange (Built into the protocol)✗No exchange in the Neptune Cash consensus rules.
Cross-chain messaging (Verified by the chain itself)✗No protocol-level cross-chain messaging.
NFTs (Carried by the chain's rules)✗Only the native-currency and time-lock type scripts are recognised, so no NFTs.

Halt, freeze or reversal, 2025-07-05✗After an undetectable inflation bug was found on 4 July 2025, the team abandoned the February 2025 chain at block 21,310 and relaunched from a new genesis (5 Aug 2025) holding the premine plus a claims fund; old holders had to redeem their balances with ownership proofs.
Halt, freeze or reversal, 2026-01-21✗A Triton VM soundness flaw (proofs could be forged) was disclosed; the network stopped until v0.6.0 on 3 Feb 2026, which rolled the chain back to block 23,400, discarding about a week of history.

Twenty criteria, weighted equally. The Cryptocurrency Standards have five sections: sound money (six qualities: scarcity, durability, fungibility, portability, divisibility, verifiability), scalability (four measures and three features), security (miner pay and seven checks), decentralisation (censorship resistance, no central team, who can mint, nodes, holders, premine, fundraising and developer share) and privacy (five checks); programmability (token issuance, smart contracts and five checks) follows them. Provisional: criteria marked — are not yet measured and are left out of the average. A rating of structure and market depth, not a price forecast or investment advice.

The genesis coinbase (1.4236672e37 base units at 4e30 per NPT) equals 3,559,168 NPT = 831,488 premine + 21,310 x 128, which confirms the premine figure. The explorer's 'fee' field shows about half of each coinbase passed to the guesser.

The work behind it

No source we can reach publishes a hashrate for Neptune Cash.

What a regulator has said

No SEC/CFTC determination — unclassified.

The regulator's position, reported as stated, not CoinSpectrum's. Assets nobody has ruled on are left unclassified rather than sorted by a guess.

How CoinSpectrum ranks Neptune Cash

Neptune Cash is #268 among cryptocurrencies and #1680 in the market ranking, which lists wrapped coins, staked derivatives, stablecoins and tokens alongside them. CoinSpectrum counts an asset once, and counts only cryptocurrencies: assets with their own blockchain and their own consensus. A wrapped coin, a staked derivative or a stablecoin is a claim on something already counted; a token, memecoin or otherwise, runs on another chain's blocks. All of them are listed, each in its own section, and none is added to the total. The 1412 places between Neptune Cash's two ranks are held by claims and tokens, not by other networks. The methodology sets out the rule and the counting rule argues for it.

The price above is the median of the exchanges the site reads live, checked every minute and cross-checked against a market snapshot (how market data is gathered). The grade is scored on published criteria, each with its source (the method). The site is independent, nothing on it is a paid placement, and its statements are signed (about CoinSpectrum, the manifesto).
