Dan Finlay is leaving. The co-founder of MetaMask, the Ethereum wallet that helped onboard tens of millions of people into decentralized finance, announced on Thursday morning that his final day at Consensys had arrived, closing out more than 10 years of building what became one of the most widely used pieces of infrastructure in all of crypto.
Finlay cited burnout as the primary reason for stepping away, and said he plans to dedicate more time to his family. “Wishing the team the best — they have an amazing road ahead of them,” he wrote in a post on X, the platform formerly known as Twitter.
For a founder to leave on those terms, no drama, no acrimony, just a decade of work and a quiet exit, is uncommon enough in crypto to deserve attention. MetaMask was, in many ways, the front door to Ethereum itself.
The wallet that defined a generation of crypto users
Finlay co-founded MetaMask in 2016 alongside Aaron Davis, operating under the umbrella of Consensys, the blockchain software company founded by Ethereum co-founder Joseph Lubin.
What started as a browser extension for interacting with Ethereum dApps, decentralized applications, grew into something far more consequential.
At its peak usage, MetaMask reported around 30 million monthly active users, making it the default wallet for DeFi traders, NFT collectors, developers testing smart contracts and ordinary users entering the space for the first time.
The wallet’s design philosophy, shaped heavily by Finlay, centered on putting users in control of their own keys and their own permissions. That philosophy, self-custody as a non-negotiable, is easy to take for granted now, but in 2016 it was a genuinely radical product decision.
Finlay pointed to the launch of Advanced Permissions, a new feature he seemed particularly proud of leaving behind.
A parting gift: crypto’s answer to recurring payments
Advanced Permissions, built on a technical standard called ERC-7715 and part of MetaMask’s Smart Accounts Kit, lets users approve exactly what a decentralized app can do in a single interaction, and then allows that app to execute within those defined limits going forward without asking for approval every time.
To understand why this matters, some context helps. Historically, every interaction between a MetaMask wallet and a dApp required the user to manually confirm each transaction. That meant repeated pop-up windows, constant app-switching between the wallet and whatever application you were using, and a growing habit among users of approving things without reading them, which created real security risks.
There was also no standard way for a dApp to request scoped, limited permissions from a wallet, which meant entire product categories, subscriptions, AI agents, time-bound access, remained difficult or outright impossible to build well.
ERC-7715 defines a method called wallet_grantPermissions, which lets a dApp ask for specific capabilities in advance. The permissions are granular in the sense that a user could, for example, authorize an app to spend 10 USDC per day to buy ETH over the course of a month. Once that permission is granted, the app can execute those purchases automatically without the user needing to sign off on each one.
The potential use cases go well beyond simple dollar-cost averaging. Subscriptions, DCA strategies, auto-compounding and AI agents operating on a user’s behalf can all now run after a single approval, rather than requiring the user to be actively present for every transaction.
Critically, the permissions are tightly scoped, constrained by asset type, spending amount and time window, and displayed to the user in plain language before anything is approved.
The reaction from the broader crypto community was largely enthusiastic. Roman Storm, the Tornado Cash co-founder who is himself navigating a fraught legal situation, federal prosecutors have asked for an October 2026 retrial after a jury deadlocked on money laundering and sanctions charges in his initial trial responded to Finlay’s post by calling the feature “extremely important.”
Storm framed it as the moment crypto could finally compete with Visa and Mastercard on one of their defining advantages: recurring payment infrastructure. “Finally, the crypto market can offer something everyone has envied about Visa and Mastercard — recurring payment systems, which crypto hasn’t had,” he wrote.
Storm’s enthusiasm may carry extra weight given his vantage point. Few people in the ecosystem have spent as much time thinking about what onchain payments can and cannot do under the existing permission model, or what it costs users and developers when that model breaks down. His endorsement of Advanced Permissions, from jail-adjacent circumstances, no less, shows how foundational the feature could be.
Finlay expressed satisfaction at seeing Advanced Permissions ship on his way out, describing it as filling a long-standing product gap, and said he looks forward to experiencing it as an ordinary user going forward. There’s something fitting about that framing. The man who spent a decade building the wallet’s permission architecture will now interact with it from the other side of the screen.
What comes next for MetaMask
Finlay’s departure doesn’t appear to signal any broader instability at MetaMask or Consensys. In his posts, he was deliberate about wishing the team well and expressing confidence in the road ahead. Still, losing a co-founder always leaves a gap, not even in only in institutional knowledge, but in the specific type of conviction that comes from having built something from scratch.
MetaMask continues to operate in a competitive wallet market. Alternatives like Rabby and Rainbow have made gains by focusing on cleaner user interfaces, and Finlay himself acknowledged before his departure that MetaMask had recognized the need to keep pace with “very rapid, hot competition.”
The Advanced Permissions launch may suggest the team is betting on feature depth and developer infrastructure as its long-term differentiator, compared to trying to win purely on aesthetics.
The MetaMask token, long discussed and long delayed, remains an open question. As recently as earlier this year, Finlay had described the prospect of a native token as still a “maybe,” though Consensys CEO Joseph Lubin has since confirmed one is coming. Whether Finlay’s exit accelerates, delays or changes nothing about that timeline is currently unclear.
