Benefits of Superseed

About Superseed

Superseed is Layer 2 that pioneers a fresh approach to DeFi, by using a collection of components meant to empower builders by introducing the self-repaying loans. This is made possible by the CDP protocol (Collateralized Debt Position) together with the POF reward mechanism (Proof-of-Repayment), the Dynamic Repayment Vault and the Supercollateral.

Supercollateral status allows borrowers to secure interest-free loans if a 500% C-ratio is maintained. Users borrowing against Supercollateral have their loans automatically repaid using protocol-generated fees. This self-repaying debt is funded by Layer 2 sequencer profits, interest from non-Supercollateral loans, and Proof-of-Repayment revenue.

Superseed is open-source, permissionless, and Ethereum-equivalent, enabling builders to seamlessly create using familiar tooling and infrastructure.

Superseed is built on the Bedrock release of the OP Stack, which aims to resemble Ethereum. There are few differences between building on Superseed and Ethereum such as: opcodes, address aliasing, transaction fees, EIP-1559 parameters or mempool rules.
