Senior Solidity Engineer
The first blockchain that repays your debt
Projects
About Superseed
Superseed is the first blockchain that repays your debt, introducing self-repaying loans as a new financial primitive where network fees fuel a better onchain experience. It is powered by Proof of Repayment (PoR), a mechanism designed to programmatically reward anyone who repays the loans of Supercollateral borrowers. At the heart of Superseed lies the empowerment of builders, where contributing to the ecosystem is rewarded. Built on the OP-stack and natively EVM-equivalent, Superseed allows Ethereum applications to deploy seamlessly. The project is designed for collective growth and supports builders on the onchain frontier.
