CIRO unveils new crypto custody framework for Canadian trading platforms

In a bid to respond more “quickly to crypto failures,” such as the collapse of QuadrigCX, Canada’s top investment industry regulator rolled out a new digital asset custody rules tightening standards on digital asset custody.

The industry-led Canadian Investment Regulatory Organization (CIRO) said its new Digital Asset Custody Framework is designed to allow it to respond more quickly to risks, including hacking, fraud, weak governance and insolvencies that have left investors exposed in past incidents.

“Many of the expectations in the framework were developed in close consultation with [crypto-asset trading platforms] and their custodians and reflect practices already in place,” a CIRO spokesperson told CoinDesk, adding that transition considerations will be applied on a case-by-case basis.

“The new framework also provides a balance between flexibility and risk management, supporting innovation while ensuring strong investor protection,” the spokesperson added.

Deeply involved in the collapse

The collapse of QuadrigaCX in 2019 remains one of the most notorious failures in Canada’s crypto history, with $123 million still unaccounted for. Its CEO, Gerald Cotten, died, and customer funds were found to be missing. Later investigations described co-founder Michael Patryn as allegedly being deeply involved in the exchange’s operations during the period when misappropriations occurred.

“Custody is one of the most critical points of risk in the crypto ecosystem,” said Alexandra Williams, CIRO’s senior vice president of strategy, innovation and stakeholder protection.

A central feature of the guidance is a tiered, risk-based structure that allows firms to diversify and strengthen custody arrangements while maintaining robust investor protections.

Early signs that expectations must be updated

CIRO said it would treat emerging custody and cyber risks, repeated supervisory issues across firms, or shifts in market practices as early warning signs that expectations may need to be updated.

“If we see that expectations are no longer aligned with how custody risk is manifesting in practice, CIRO would update the framework proactively, rather than wait for a failure to occur,” the regulator said.

Canada has taken a cautious approach to crypto regulation, bringing trading platforms under existing securities rules and emphasizing investor protection through registration, custody and disclosure requirements. More recently, federal moves on stablecoins and an expanded oversight role for the Bank of Canada suggest a slow shift toward a broader national framework for digital assets.

CIRO, a self-regulatory body that set standards for investment dealers, mutual fund dealers and trading activity in Canada, possessing the quasi-judicial authority to investigate misconduct and enforce disciplinary actions, including fines, suspensions, and permanent bans.

Ethereum Dust Attacks Have Increased Post-Fusaka

Ethereum Dust Attacks Have Increased Post-Fusaka

Stablecoin-fueled dusting attacks are now estimated to make up 11% of all Ethereum transactions and 26% of active addresses on an average day, after the Fusaka upgrade made transactions cheaper, according to Coin Metrics. 

Ethereum is now seeing more than 2 million average daily transactions, spiking to almost 2.9 million in mid-January, along with 1.4 million daily active addresses — a 60% increase over prior averages.

The Fusaka upgrade in December made using the network cheaper and easier by improving onchain data handling, reducing the cost of posting information from layer-2 networks back to Ethereum.

Digging through the dust on Ethereum

Coin Metrics said it analyzed over 227 million balance updates for USDC (USDC) and USDt (USDT) on Ethereum from November 2025 through January 2026.

It found that 43% were involved in transfers of less than $1 and 38% were under a single penny — “amounts with insignificant economic purpose other than wallet seeding.”

“The number of addresses holding small ‘dust’ balances, greater than zero but less than 1 native unit, has grown sharply, consistent with millions of wallets receiving tiny poisoning deposits.”

Pre-Fusaka, stablecoin dust accounted for roughly 3 to 5% of Ethereum transactions and 15 to 20% of active addresses, it said. 

“Post-Fusaka, these figures jumped to 10-15% of transactions and 25-35% of active addresses on a typical day, a 2-3x increase.”

However, the remaining 57% of balance updates involved transfers above $1, “suggesting the majority of stablecoin activity remains organic,” Coin Metrics stated.

Users need to be wary of address poisoning

In January, security researcher Andrey Sergeenkov pointed to a 170% increase in new wallet addresses in the week starting Jan. 12, and also suggested it was linked to a wave of address poisoning attacks taking advantage of low gas fees

These “dusting” attacks typically involve malicious actors sending fractions of a cent worth of a stablecoin from wallet addresses that resemble legitimate ones, duping users into copying the wrong address when making a transaction.

Sergeenkov said $740,000 had already been lost to address poisoning attacks. The top attacker sent nearly 3 million dust transfers for just $5,175 in stablecoin costs, according to Coin Metrics.

Dust does not represent genuine economic usage

Coin Metrics reported that approximately 250,000 to 350,000 daily Ethereum addresses are involved in stablecoin dust activity, but the majority of network growth has been genuine.  

“The majority of post-Fusaka growth reflects genuine usage, though dust activity is a factor worth noting when interpreting headline metrics.”
