Full Stack Developer

Who Are We?

Legacy is a non-custodial, one-click DeFi wallet with Inheritance feature that makes wealth management in digital assets as simple as logging into your bank.

Legacy allows you to swap across chains, earn yield, buy tokenized stocks and protect your wealth for generations to come - all in one place.

No gas fees. No seed phrases. No transaction signing. Just simple, non-custodial, borderless finance.

Legacy is an early stage startup that was born because our sister company’s Decentralized Masters users asked for a solution to their everyday problems with crypto. Decentralized Masters is the fastest growing education company in the crypto space - scaling from 2 founders to 120+ people and on track for $50m in revenue this year. Now we’re distilling everything we learned about user habits, adoption and their problems into a single product: Legacy.

This is an opportunity to join the core team of 5 with an impressive track record, pre-funding that is already generating revenue.

Our Edge

Fintech in the front, blockchain in the back. We believe the next wave of adoption won’t come from Metamask-style extensions - it will come from products that feel like modern finance apps that are powered by web3 beneath the surface.

User Distribution

Unlike most crypto startups fighting for the same users, we already have a built-in distribution channel of non-crypto investors through our sister company, Decentralized Masters - thousands of people learning about digital assets for the first time and choosing Legacy as their main wallet. The same team that build Decentralized Masters from $0 to $80m in total revenue is now bringing that marketing machine to Legacy.

Our Vision

Our goal is to become the top 10 brand in the industry by creating the largest DeFi ecosystem the world has ever seen. People who have never used DeFi because it’s too complicated are now earning yield and their assets are protected by the Inheritance feature for the generations to come.

Are You Ready?
