Finally
know
what
your
crypto
is
really
earning you
Exchanges, wallets, DeFi: your whole portfolio in one place. Cost basis, gains and losses are worked out for you. No spreadsheet.
Fictitious portfolio, indicative figures.

Your crypto is scattered.
So are your numbers.
Three exchanges, two wallets, one spreadsheet that is never up to date. Crypto Master brings it all together and does the maths.
“How much do I have in total?”
Every account and wallet in a single dashboard. One total, at last.
“Am I up or down?”
Cost basis and gains are worked out for each coin, from what you actually paid.
“I spend my evenings in Excel.”
Link an account or drop in an export. Crypto Master imports, sorts and calculates for you.
Your answers, at a glance
These screens come from the demo portfolio: a fictitious portfolio, indicative figures. Open it, no sign-up needed.
Where your money is, in one look
Bitcoin, altcoins, stablecoins: the weight of each bucket, across all your accounts. You see at once where you are over-exposed.
What you really paid, coin by coin
Ten buys on three platforms? One cost basis. And your gain, at today’s price.
What each coin has earned you
Gains you have banked on one side, unrealised gains on the other. Position by position, with no maths to do.
What you put in.
What it is worth.
Two lines for the only question that matters: are you above what you put in?
A snapshot of your portfolio at every month end
Contributions, value, performance for the month. Open a month to see what you held.
Every transaction in a single list
Buys, sells, deposits, rewards: all in one place. Filter by coin, account or type.
From your exports to your French form 2086
Every spring you have to rebuild your figures for the tax office. Crypto Master already has them: it works out your capital gains sale by sale. You copy them into impots.gouv.fr, and filing stays yours.
“How much do I have to declare?”
The amounts of your form 2086, sale by sale, from your real transactions. The detail of every sale is right in front of you.
“What if my data is incomplete?”
An unknown price is never counted as zero without you knowing. You get a range, a reliability rate and the list of what is left to complete.
“Do I have accounts abroad to declare?”
The 3916-bis help lists your platform accounts for the year, and what the form asks for each.
Your form 2086 from 0 €, and 2,99 € incl. VAT a month for up to 3,000 transactions.
Form 2086, the 3916-bis help and their PDF documents are included in every plan, free included. The only limit is your plan’s, in accounts and transactions. The amounts are indicative: you remain responsible for your return.
Built for people with crypto everywhere
Cost basis and gains
Worked out from what you actually paid, even across years and several platforms. Realised and unrealised, kept apart.
Exchanges, wallets, DeFi
Binance, Kraken, Ledger, MetaMask, Bitcoin, Aave, Uniswap… Everything you hold, consolidated coin by coin.
Automatic updates
Your wallets sync every time you sign in. Exchanges linked by API are picked up on their own.
Zero duplicates
Import the same file twice: not one duplicated row. Your history stays clean.
Read-only
A public address, or an API key with no withdrawal rights. Your keys are encrypted.
DeFi, finally readable
Aave, Compound or Morpho loans, Uniswap and Aerodrome pools: what each position has earned, net of gas fees.
Unwanted tokens filtered out
Tokens sent to you unasked are spotted and hidden. They never distort a total.
Wherever your crypto lives, Crypto Master is there too

Plans count your whole imported history, not just the year’s transactions: several years of trading may call for a higher plan.
A “connected account” is an exchange or a crypto wallet that you link — not a user. A Binance account and a Ledger count as two accounts; one wallet followed on several networks (a 0x address on Ethereum, Base and Arbitrum, or a Phantom with its Solana, 0x and Bitcoin addresses) counts as one.
Reached your limit? Nothing is deleted or hidden: what is already imported stays displayed and calculated. Only new transactions and adding an account are refused, until you change plan.
The form 2086 simulator and the 3916-bis help are included in every plan, free included: the only limit is your plan’s accounts and transactions. See the calculation method.
