8 Numbers That Prove Self-Custody Has Arrived (Stablecoin Edition)

"Do people actually self-custody?" "Do people actually use stablecoins in self-custody?" 

It's the question VCs, founders, and traditional finance keep asking. The answer isn't in whitepapers or roadmaps. It's in the data.

Safe smart accounts have become the infrastructure layer for stablecoin self-custody at scale. From DeFi yields to Visa card payments, from institutional treasuries to consumer apps with millions of users, the numbers tell the story.

Here's the proof.

 #1: $105 Billion: Stablecoin trading volume on CoW Swap

1.9M trades. MEV protection. Full self-custody. That's more volume than most centralized exchanges. CoW Swap proved institutions will trade onchain if you give them real forex rates without forcing them to give up their keys. Onchain forex infrastructure already exists. It's processing more than $100B.

 #2: $57 Billion: USDC transferred through Safe since 2023

Monthly volumes tripled from $1.5B to $4.1B in 18 months. With $25.3B already processed in 2025, Safe is on track to nearly double last year's full volume. Adoption is not just growing, it's compounding.

#3: $7 Billion: Stablecoins currently secured in Safe accounts

Across Ethereum, Base, Arbitrum, Polygon, and more. USDC, USDT, DAI, EURe. Multi-chain, multi-asset, battle-tested infrastructure. $7B sitting in self-custody isn't a demo. It's working capital.

#4: €1.2 Billion: EURe moved by 17,000 Safe owners via Monerium in 12 months

That's 25% of all Monerium volume flowing through Safe wallets. Regulated euro stablecoins with IBAN integration, instant payments, and DeFi access. European businesses aren't waiting for banks to get onchain. They're already there. Stablecoin infrastructure isn't just dollars. Euros work too. 

#5: $145 Million: Transacted by 31,000 Picnic users

Do the math: that's ~$4,600 per user. These aren't holders waiting for number-go-up. They're on-ramping, off-ramping, topping up Gnosis Pay cards, and actually using stablecoins daily. Consumer stablecoin apps are real. Self-custody can be as easy as Venmo. Picnic proved it on Safe.

#6: $105 Million: Crypto card payments through Gnosis Pay

115,000 merchants. 10,000 cities. 130 countries, in 5 continents.

Hold stablecoins in self-custody, swipe anywhere Visa works. The bridge between crypto and checkout counters is already built. Your coffee shop accepts crypto. It just doesn't know it yet.

#7: 2.3 Million: USDC holders on World Chain powered by Safe smart accounts

Consumer crypto at scale. Millions of people managing stablecoins in self-custody through World's identity-verified infrastructure. Distribution that rivals traditional fintech apps. Self-custodial stablecoins reached millions of users. Not someday. Today.

#8: 200+ Institutions: Earning DeFi yield via Morpho x Safe Earn

Institutional treasuries and DAOs accessing DeFi yields directly within Safe. No custody handoff. No third-party risk. Just programmable multi-sig security meeting capital efficiency.

Treasury management evolved. Institutions can earn yield in DeFi without giving up their keys. They're already doing it.

What This Actually Means

Each number alone is impressive. Together they show something bigger: a complete stablecoin infrastructure stack running entirely in self-custody.

Consumer apps with millions of users. Institutional treasuries earning DeFi yields. Card payments at corner stores across 130 countries. Multi-billion dollar trading infrastructure. Euro stablecoins with IBAN integration.

Safe isn't one use case. It's the security layer these partners chose to build on because it works. Programmable multi-sig security. Battle-tested with $60B in assets. Powering nearly 4% of all Ethereum transactions.

The question was never "will people use stablecoins in self-custody?" The data answered that months ago.

The real question: which infrastructure will win?

Safe already did.
