About
Bilan Crypto: your crypto in euros, overview, history and taxes
Bilan Crypto (bilancrypto.fr) is a French site that rebuilds an individual's crypto portfolio in euros from their public addresses: each token's value and its evolution, the history of all their operations and an estimate of the tax due in France. It works read only: no signature, no private key, no funds received or sent.

In brief
- Free for the overview, the history and the tax estimate; no sign-up for a first overview.
- Read only: a public address is enough (0x…, bc1…, Solana, Tron). The site never asks for a recovery phrase.
- Ethereum and 48 other compatible networks (Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Linea, Scroll, zkSync, Mantle, Sonic, Berachain, HyperEVM…), plus Solana, Bitcoin and Tron.
- More than 900 DeFi protocols recognised (Aave, Uniswap, Lido, Curve, Pendle, Morpho, Ethena, Jupiter, Hyperliquid…).
- Centralised exchanges with a read-only API key (Kraken, Binance, Coinbase, Bitpanda, Bitstamp, OKX, Crypto.com Exchange, KuCoin, MEXC) or by statement import (Crypto.com app, Nexo, Revolut, Trade Republic, SwissBorg).
- Three reading levels, chosen by the visitor: Beginner, Intermediate, Expert.
- One crypto story a day, written at these three levels.
- Tax computation under French rules: capital gains at weighted average cost (article 150 VH bis, form 2086).
Who is it for?
For every individual holding crypto in France, from the first purchase to a multi-network DeFi portfolio. The visitor picks their level in one click: Beginner (no jargon, every term explained), Intermediate (the essentials, with figures) or Expert (all networks, position and computation details). The words, the explanations and the day's news adapt to this choice.
What the site does
Overview
The portfolio's value in euros, and for each token held: its price, the chart over the last 24 hours, its change over 7 days, 1 months, 1 year and since purchase. Without an address, the home page shows the market's top ten the same way.
DeFi and CeFi positions
Open positions in protocols (loans, borrows, liquidity pools, staking, vaults) and, separately, what you hold on your exchanges: what is deposited, what the position earns, token by token, and the protocol's known incidents. The same detail as on Bilan DeFi.
History
All operations, dated and labelled: purchases, sales, swaps, bridges between networks, exchange deposits and withdrawals, rewards, network fees. Transfers between your own addresses are recognised and neutralised.
Taxes
A tax range straight away, then the detailed computation under French rules: capital gains at weighted average cost (article 150 VH bis of the French tax code, form 2086), crypto-to-crypto swaps tax-deferred, accounts held abroad (form 3916-bis).
Today's news
Every morning, a crypto story chosen for its effect on French holders (hack, regulation, market move), written three times: for the beginner, the intermediate and the expert, with its sources.
What Bilan Crypto does not do
- It holds, receives and sends no funds, and never asks for a recovery phrase or a signature.
- It gives no investment advice: the figures are information.
- It does not file your tax return for you and does not replace a chartered accountant for a complex case.
Pricing
The overview, history and tax estimate are free. Last year's tax report (an automatically generated PDF) costs 0.99 to 19.99 euros depending on activity. A file prepared and signed off by a chartered accountant is on quotation, from 499 euros before tax.
Data and privacy
The overview is computed on request and not stored. An optional account remembers your addresses for next time; you can remove them at any time. No data is sold. Details: your data, security.
Who is behind Bilan Crypto?
Bilan Crypto is published by Delille Consulting, a French company based in Paris, which also publishes Bilan DeFi, the sister site dedicated to DeFi position details. Both sites share the same computation engine. Contact: contact@bilandefi.fr.

Frequently asked questions
What is Bilan Crypto?
Bilan Crypto (bilancrypto.fr) is a French site that rebuilds an individual's crypto portfolio in euros from their public addresses: each token's value and its evolution, the history of all their operations and an estimate of the tax due in France. It works read only: no signature, no private key, no funds received or sent.
Is Bilan Crypto free?
Yes for the overview, your operation history and the tax range. Last year's tax report, an automatically generated PDF, costs 0.99 to 19.99 euros depending on your activity. A file prepared and signed off by a chartered accountant is on quotation, from 499 euros before tax.
Do I need to connect my crypto wallet or give a key?
No. A public address pasted in the field is enough. Connecting a wallet, always read only, is just a way to find your other addresses. Bilan Crypto never asks for a recovery phrase or a transaction signature.
Which networks and exchanges are supported?
Ethereum and 48 compatible networks (including Base, Arbitrum, Optimism, Polygon and BNB Chain), Solana, Bitcoin and Tron, more than 900 DeFi protocols, and centralised exchanges with a read-only API key (Kraken, Binance, Coinbase, Bitpanda, Bitstamp, OKX, Crypto.com Exchange, KuCoin, MEXC) or by statement import.
What does the Overview tab show?
Two parts. The tokens held, each with its value, its price chart over 24 hours and its change over 7 days, 1 months, 1 year and since purchase. Then the open DeFi positions (loans, pools, staking), detailed in the DeFi and CeFi positions tab. Without an address, the home page shows the top ten by market cap the same way.
How is the gain since purchase computed?
From your history: the price at the last swap that brought you the token, otherwise the average price of everything that came in. When some movements remain unexplained, the figure is preceded by ≈.
Does Bilan Crypto fill in my tax return?
It estimates the tax and prepares the amounts for French form 2086 under French rules (weighted average cost, crypto-to-crypto swaps deferred). You remain the filer: it is a computation aid, not tax advice.
What happens to my data?
The report is computed on request and not stored. Addresses are only remembered if you create an account, and you can remove them at any time. No data is sold.
Who publishes Bilan Crypto?
Delille Consulting, a French company based in Paris, which also publishes Bilan DeFi (bilandefi.fr), the sister site dedicated to tracking DeFi positions. Both sites share the same computation engine.
How is it different from Bilan DeFi?
Bilan DeFi details DeFi positions (loans, pools, staking) and their yield, tab by tab. Bilan Crypto gets to the point for every crypto holder: four tabs (Overview, DeFi and CeFi positions, History, Taxes), live prices and the day's news explained at your level.
What is the €10,000 challenge?
Bilan Crypto's €10,000 challenge (bilancrypto.fr/defi) is a free game with fictional money: each participant receives a €10,000 portfolio to invest in crypto (Bitcoin, Ethereum…), DeFi investments (Aave, Morpho, Aerodrome…), managed accounts and leveraged positions on Hyperliquid, at real prices and rates, fees included. The highest portfolio on 31 2026 December at 00:00 (Paris time) wins a JVC Exofield Dolby Atmos headset; second place €200 in bitcoin, third a new Trezor. No real money is involved.
