How Magic Labs made crypto wallets accessible to 50 million users

Executive overview

Blockchain's early UX was a barrier: seed phrases, browser extensions, unreadable signing prompts. Most potential users quit before finishing setup.

Sean Li and Jaemin Jin built Magic Labs to strip that friction away — email login, invisible key management, no crypto jargon required. Their patented delegated key management system provided non-custodial security without burdening users.

The core insight: the best UI is no UI — technology that disappears into the background so users focus on outcomes, not infrastructure.

Founder backgrounds and the founding moment

• Sean Li studied software engineering at Waterloo, co-founded KiteMatic (acquired by Docker, now Docker Desktop)
• Jaemin Jin joined Uber early in 2015, rode the hyper-growth phase, then worked at Apple on tokenization pipelines
• Both encountered Ethereum independently around 2016–17 and saw the same broken onboarding experience
• Reconnected at an arcade bar in San Francisco in 2018; a five-hour conversation crystallised the idea
• Core question: why had no one built a simple email login for blockchain?

The problem they were solving

• Before Magic, using a blockchain required downloading a browser extension, writing down a seed phrase, and signing unreadable messages
• Gas fees and jargon compounded the confusion; most users gave up before completing setup
• The dominant ideology insisted users must self-custody private keys — any abstraction was treated as heresy
• This dogma deterred builders from even exploring custodial alternatives, leaving the problem unsolved

Inventing delegated key management

• Magic's solution: email, phone number, and social login mapped to a crypto wallet created silently on the backend
• The challenge was proving non-custodialness — developers and investors feared centralised key management after exchange hacks
• Pressure from sales calls and investor due diligence forced the team to solve the problem technically
• Result: the first non-custodial key management patent, delegated key management, which balanced web2 login with web3 security
• The patent was a decisive factor in closing their seed round during the 2018 bear market

Surviving the bear market and near-death moments

• The 2018 crypto downturn wiped out most competitors; Magic treated it as a filter, not a threat
• The team came within one month of running out of runway
• They were transparent with their eight-to-ten person team about the payroll risk
• Sean took a personal loan to ensure funds hit the bank before the round closed
• Hiring and office search continued in parallel — no pause, no retreat

Scaling to enterprises

• Magic became the first embedded wallet to achieve SOC 2 Type 2 compliance, even before pursuing enterprise clients
• That standard opened doors: enterprises were impressed a startup held it
• Also achieved ISO payment compliance — now the most compliant embedded wallet solution available
• Enterprise clients include Macy's and Mattel; crypto applications include Polymarket, Helium, and Immutable
• PayPal Ventures led a round that brought total funding to over $80 million; at that point Magic had 30 million wallets, now 50 million and 200,000 developers

Product philosophy: technology as storytelling

• Product design is not just problem-solving — it is a message about what the company stands for
• Identify the wow factor and surface it to users as fast as possible (Sean's Apple lesson: Steve Jobs obsessed over the computer saying "hello")
• Perfection has its place, but only after fast iteration surfaces real user patterns
• One extra authentication step causes measurable conversion drop-off; every detail compounds

The Newton Protocol and the AI agent layer

• Magic's next layer: Newton Protocol, described as the world's first policy protocol for onchain interactions
• In five years, AI agents will manage money, contracts, and travel autonomously on users' behalf
• Newton acts as a permission engine — like iOS controlling which apps can access location or camera — but for AI agents interacting with blockchains
• Users set guardrails; Newton enforces them so agents can act safely even without active oversight
• Crypto becomes the financial rail for AI agents; Magic's onboarding solved the human problem, Newton solves the agent problem

Founder advice

• Progress is not linear — commit to a mission, but stay flexible on strategy and approach
• Treat friction points as signals, not obstacles; they reveal truths others have not found
• Stress-test how deeply you care about the problem before starting, not after the first crisis hits
• Obsession is the filter: if you have other goals (money, status), startups will break you
• Personal motivation evolves — early on it is skill-building; later it is category leadership and new creative challenges
