Smart Contract Developer Jobs in Seattle, WA (NOW HIRING)

We are the modular stablecoin infrastructure. It gives businesses everything they need to launch a stablecoin built around their product, with separate, configurable layers for application, distribution, and issuance. Choose your regulated issuer, with the option to switch them later. Design how your stablecoin behaves with templates and custom logic. Tap shared liquidity across the network from day one. Other stablecoin platforms bundle every layer into a single fixed stack. We keep them independent, so your stablecoin stays yours.
