About Usual:

Usual was born from a simple observation: dominant stablecoins operate like centralized banks — they capture bilions of revenue and don’t redistribute it. In parallel, most crypto tokenomics have failed to deliver long-term fairness, favoring insiders over users.

We’re here to change that.

Usual is the first stablecoin protocol that gives back the ownership and the value to its users. By turning users into stakeholders, we’re pioneering a new, more equitable financial infrastructure — one where value flows back to the community.

In just a few months, we built and launched a full protocol from scratch, introduced a new kind of stablecoin backed by tokenized US Treasuries (USD0), its yield-bearing counterpart (USD0++), and a revenue-sharing governance token ($USUAL).

The protocol quickly reached $1.8B in TVL before stabilizing around $800M during a period of major product and governance upgrades.

We’re a small, highly committed team of DeFi natives with a strong execution track record and a deep ambition to reshape how value circulates in crypto.

Joining Usual means working at the frontier of decentralized finance, owning your scope, moving fast, and collaborating with some of the best minds in the space.

Context:

At Usual, you'll be part of a talented team of around 10 engineers, including our CTO, VPE, 5 smart contract developers, and 3 dApp developers. Our protocol is live, and we're gearing up for the release of V1 in the coming weeks. This next phase will build on our current prelaunch version, focusing on enhancing functionality, security, and user experience.

Mission:

As a Senior Smart Contract Developer at Usual, you will play a critical role in designing, developing, and deploying smart contracts that form the backbone of our protocol.
