Crypto deposits and withdrawals,
run the way a regulator expects.

There is no single answer, and the answer changes. Three regulators that poker operators often meet show the range.

Curaçao's Gaming Authority published a crypto guideline for its licensees in June 2026. It treats crypto as high risk, prefers fiat-backed stablecoins, requires blockchain analytics at deposit and at withdrawal, bans funds from sanctioned wallets and mixing services, and requires player, operational and treasury wallets to be kept apart, with full compliance due by June 2027.

The Malta Gaming Authority replaced its earlier sandbox with a policy on distributed ledger technology on 30 January 2023. A licensee that wants to accept virtual financial assets needs the MGA's prior approval, and may use a provider authorised under Malta's Virtual Financial Assets Act to take the crypto, so that the operator itself deals only in fiat.

Great Britain's Gambling Commission said in 2016 that anyone offering gambling to British consumers with virtual currencies needs an operating licence. It rates cryptoassets as a high-risk payment method, and its guidance lists what a licensee accepting crypto must have addressed, from source of funds to the effect of price swings on deposit limits and anti-money-laundering triggers.

A poker room's books, limits and reports are in money: euros, pounds, dollars. A deposit in a volatile coin is worth one amount when it is sent, another when it is confirmed and a third when it is withdrawn. That moves the player's deposit limit, the anti-money-laundering thresholds and the operator's own exposure, which is exactly the problem the UK Gambling Commission names when it lists price fluctuations among the issues a licensee must address. Curaçao's guideline answers it by preferring fiat-backed stablecoins.

Stablecoins reduce the problem; they do not abolish it. On 11 March 2023, after Circle disclosed that $3.3 billion of USDC's reserves were held at the failed Silicon Valley Bank, USDC traded at about 88 cents. A cashier that credits a dollar for every stablecoin regardless would have paid out of the operator's pocket that weekend.

PokerEnginePro takes three assets only: USDT and USDC on Ethereum, and USDT on Tron. Each deposit is converted to the player's fiat currency as it arrives, with the rate, its source and the time recorded and the amount rounded down, so the books never hold a coin. Rates come from a market-data vendor independent of the custodian, and if a stablecoin drifts more than 1.5 per cent from its peg (the operator's setting) deposits are held for a person and no withdrawal is quoted. If the rate moves more than 2 per cent between a withdrawal's quote and its payout, the player is shown a new quote to accept or cancel.^[7][1][8]

Operators often talk about 'a crypto provider' as if it were one thing. It is three. Custody holds the keys and the coins, and decides who can move them. Processing gives each player a deposit address, watches the chain, and pays out, often converting to fiat on the way. Screening, known in the trade as KYT (know your transaction), checks every address and transfer against what is known on chain: sanctioned wallets, mixers, stolen funds, darknet markets.

Each has its own provider category. Fireblocks describes itself as digital asset and stablecoin infrastructure, with wallets and custody for institutions. CoinsPaid offers payment infrastructure to accept, process, convert and settle digital-asset payments. Chainalysis KYT monitors transactions in real time and raises alerts on risky transfers. Curaçao's guideline makes blockchain analytics mandatory for its licensees at both deposit and withdrawal.

Around them sits the travel rule. In the European Union, Regulation (EU) 2023/1113 extends the duty to send information about the originator and beneficiary of a transfer to crypto-asset service providers, in line with the Financial Action Task Force's standards, and the European Banking Authority's guidelines on it apply from 30 December 2024. It binds the providers that move the crypto, which is one more reason to choose custody and processing partners that are authorised for the markets you serve.

PokerEnginePro integrates Fireblocks for custody, CoinsPaid for processing and Chainalysis for screening, chosen per market like any other vendor. Every confirmed deposit and every withdrawal address is screened: high risk holds the money and raises an anti-money-laundering alert, severe needs a second approver, and a screening that cannot be made is never read as no risk.^{[10][11][12][1][9]}

A crypto deposit is not a card authorisation. It is final only when the network says so, it can arrive in the wrong asset or on the wrong network, it can be too small to be worth crediting, and it can come from someone the operator cannot identify. A cashier has to handle every one of those without losing a coin.

PokerEnginePro credits a deposit after 12 confirmations on Ethereum and 20 on Tron. It is then valued in fiat, screened, and credited exactly once, however often the vendor reports it. A deposit in the wrong asset, to an address never issued, that cannot be attributed, below the minimum, from a market without crypto, refused by the identity or safer-gambling checks, or rated high risk waits for a person to decide; money on chain never expires. A refused deposit is returned to its source address by Finance with a second approver and the network fee deducted, and a sanctioned or high-risk one is frozen and escalated to the money-laundering reporting officer instead.

The classic way to launder money through a gaming account is to put it in one way and take it out another. The answer is the closed loop: money goes back the way it came. For crypto that means the same asset on the same network, and no more than the player put in that way.

PokerEnginePro lets a player withdraw crypto only in an asset and on a network they have deposited with, and no more than their net deposits there. Withdrawal addresses are checked by EIP-55 checksum on Ethereum, with an address typed in a single case shown back in its checksum form for the player to confirm, and by Base58Check on Tron; the platform's own addresses are refused. The player pays one flat network fee per network, shown in the quote, and the operator absorbs the real gas. Large withdrawals need a second approver, like any other payout.
