Buy, sell, and swap crypto easily, flexibly, reliably, and optimally, even for large amounts.

market operationsNo worries or technical complications: you place the order, CheckSig executes it. because buying and selling, even for significant amounts, should not be complicated. And you can also set up an accumulation plan to mitigate the risks of market timing and volatility.
You can trade with various order types: instant (market, executed at the best available price), recurring (executed at a chosen frequency over time), or fixed price (limit, executed only if the price reaches the specified level).
For amounts up to €60,000, order execution is automatic and immediate 24/7. For larger amounts, orders are handled by our brokerage desk (active 9:30 AM–6:00 PM on business days) to ensure sufficient market liquidity for the specific order (order book depth). Limit orders over €60,000 are entered manually by the brokerage desk but remain active 24/7.
Optimal execution (best execution) considers the order amount, order type, market conditions, and agreements with major global exchanges we are connected to. In any case, we always find the best price for you and offer extremely competitive transaction fees.
You can trade all major crypto-assets: we support those listed on multiple exchanges and with substantial trading volumes over an extended period.

Crypto-to-crypto conversions are taxable events if they involve non-homogeneous crypto-assets. This criterion was introduced in the 2023 budget law. The Revenue Agency clarified that converting crypto like Bitcoin or Ether into stablecoins like USDC or USDT is taxable, because these stablecoins can be converted into fiat currency by the issuer.
However, conversions of Bitcoin or Ether into DAI, DAO, or PaxGold are not taxable, as these cannot be converted into fiat currency by the issuer. Among the crypto-assets supported by CheckSig, only USDC is considered non-homogeneous with others.
If you’ve chosen CheckSig as your tax substitute and the conversion is taxable, we handle the substitute tax on any capital gains or record any losses for future compensations.

We only support crypto-aseets that have demonstrated substantial trading volumes over an extended period. Additionally, to ensure operational continuity, we only select coins listed on multiple exchanges. If you’re interested in a particular coin and the amount you wish to trade is significant, please contact our support team (either via email at support@checksig.com or WhatsApp +39-378-304-3902): we’ll do our best to accommodate your request.
Absolutely!
An accumulation plan is a smart strategy to minimize the risks of market timing and mitigate volatility. Many investors underestimate its power in long-term saving and investment strategies.
To set up an accumulation plan, in the Private Area, select Buy, Recurring as order type, and choose the frequency.
And if you’re living off your crypto holdings, you can also set up a decumulation plan to sell crypto and withdraw EUR/USD funds systematically!

As required by Italian regulations applicable to intermediaries, the tax cost basis is determined according to the average purchase cost method.
If you are tax resident in Italy and have opted for the administered tax regime, this tax cost basis is used by CheckSig, in its role as withholding tax agent, to calculate taxable capital gains and losses. On realized capital gains, CheckSig applies and withholds the substitute tax, taking into account any capital losses accumulated over the previous four years for offsetting purposes.
For crypto-assets purchased through other providers and subsequently deposited with CheckSig, the purchase cost is assumed to be zero, unless you provide complete, verifiable, and consistent documentation regarding the acquisition date, purchase price, and the trading venue used.
Any documentation received will be verified against historical market data; where necessary, additional supporting documents may be requested. With respect to the adequacy of the documentation provided, CheckSig’s assessment is final and not subject to challenge.
For complex portfolio situations in which CheckSig considers the documentation to be insufficient or problematic, you may request from the Digital Gold Institute the Crypto Portfolio Report.
