Capabilities
EVM protocol design and smart contract development
Contracts that hold and move value on Ethereum and EVM chains. Security research and adversarial review shape the design, and the most critical paths are formally verified.
“[Seva's] code was audited by one of the best security firms in Web3 and there weren't any significant issues in their report.”

Token and incentive modeling
Simulation before launch: how the system behaves under pressure, and which parameters keep it stable.
Integration
Contracts connected to your backend, data, and interface, or the product built around them.
Engagement
Team augmentation
An engineer inside your team
Seva joins your team and works alongside your engineers, from first design through to launch.
“Vsevolod's diligence, attention to detail and technical skills were among our team's biggest assets.”

Custom development
A scope delivered for you
Provencraft designs, builds, and tests the work against an agreed scope, through to launch.
“[Seva] takes on complex business requirements … and distills that solution into simple code and smart contract.”

Open source
Decentralized.
Never divided.
Anyone, anywhere, can exchange value on their own terms.
Seva keeps every conversation in plain language. Good ideas should work equally well in a boardroom and a code review.
“Most impressive to me … was how good he is at communicating highly complex topics in very simple terms.”
Executive Director at Tokenized Asset Coalition
“… incredibly product- and business-minded, and a phenomenal partner to ideate, design, and build with.”
