MimbleWimbleCoin (MWC)

MimbleWimbleCoin ranks #340 of 504 cryptocurrencies. On a list that also counts tokens, memecoins, wrapped coins, staked derivatives and stablecoins it appears at #4484: 4144 of the 4483 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.

CoinSpectrum Grade (Source)

Grade pending. MimbleWimbleCoin's launch — how much went to insiders, whether it was sold to investors — is still being researched. A grade is not given until it is, so that a coin is never rated higher for what is not yet known.

Privacy (5 checks)84 of 5 passed source
Protocol level privacy (Keys not tied to an identity · Whitepaper §10)✓Mimblewimble outputs need only blinding keys anyone generates; no identity rule.
UTXO ledger (A new key for each payment · Whitepaper §2, §9)✓
Network privacy (Origin hidden by default)✓mwc-node: Dandelion++ stem relay in the transaction pool, and since 6.0.1 (Mar 2026) an embedded Tor client carries all peer connections by default.
Hidden amounts (Amounts confidential)✓Mimblewimble since launch (2019): Pedersen commitments and range proofs hide every amount.
Hidden parties (Sender and receiver hidden)✗No addresses on chain, but inputs are spent openly (no ring signatures or ZK sender hiding) and the graph is only partly hidden by cut-through.
Programmability (tokens, contracts, 5 checks)1.11 of 9 points source
Token issuance0No token issuance on the chain itself
Smart contracts0Mimblewimble chain (Grin-derived mwc-node): outputs carry no scripts, only commitments and kernels.
Multisig and time locks (Without a third party)✗Kernels carry lock heights and the wallet builds 2-of-2 Schnorr outputs for swaps, but there is no general m-of-n multisig in the protocol.
Atomic swaps (With other chains)✓mwc-wallet's swap module trades MWC against BTC, BCH, LTC, DASH, ZEC, DOGE and Ether with a multisig output and time-locked refund, working on mainnet.
Native exchange (Built into the protocol)✗The swap marketplace is a wallet feature, not part of the consensus rules.
Cross-chain messaging (Verified by the chain itself)✗MWC nodes verify no other chain; no protocol-level cross-chain messaging.
NFTs (Carried by the chain's rules)✗Transactions carry only the native coin; no token or NFT type.

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.

Supply

0 of a maximum 20,000,000 MWC are in circulation — 0.0% of the total that will ever exist.

Launch and allocation

Premine (allocated at launch)90.8% of today's supply
Developer share received since launch0% of today's supply
Developer share of new coins today0%

The genesis block pays GENESIS_BLOCK_REWARD = 10,000,000.04 MWC (consensus.rs); against ~11.02M supply at height 3,625,920 (schedule sum) that is 90.8%. Secondary sources say the 10M were split into about 6M for a Bitcoin-holder airdrop (about 5.4M actually claimed), about 2M for the developers and 2M for a HODL programme; all of it was allocated by the founders.

No ICO is reported; funding of the founding team and any sale of its 2M allocation are not documented in a primary source found.

No public or private sale is documented; whether the developer allocation was later sold is not documented.

consensus::reward pays block reward plus fees to the miner; no developer or treasury output.

The genesis 10M (half the 20M cap) dominates supply; the breakdown of airdrop, developer and HODL allocations comes from a secondary summary, not a primary document. Input circulating supply of 0 is wrong: the chain is live at height 3,625,920 with ~11.02M issued. No attack or halt found.

The work behind it

MimbleWimbleCoin is secured by 9.66 kH/s of its own work. Hashrate does not compare across algorithms — a SHA-256 hash and a Scrypt hash cost different amounts to produce.

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 MimbleWimbleCoin

MimbleWimbleCoin is #340 among cryptocurrencies and #4484 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 4144 places between MimbleWimbleCoin'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).
