The Open Credit Infrastructure for Onchain Yield

The credit engine supercharging vaults, fixed-cost borrowing, and institution-grade strategies

What is Spine Finance?

Spine Finance is a next-generation fixed-rate lending protocol built on Ethereum and EVM-compatible chains. Spine introduces a hybrid credit architecture that combines:

• an automated Central Credit Vault that aggregates and deploys liquidity

• on-chain Credit Books, structured like fixed-rate orderbooks

• curated, risk-bounded liquidity management for lenders and curators

• integrations with major lending protocols (Morpho, Euler, Aave, Compound, and more)

This architecture enables instant fixed-rate lending and borrowing, deep liquidity, transparent pricing, and flexible risk management for both institutions and individual users.

Spine brings institutional-grade fixed income to DeFi by providing predictable borrowing costs, curated yield generation, and a trust-layer that protects lenders while keeping markets fully permissionless.

For a high-level summary:

• Lenders deposit into the Central Credit Vault, which allocates liquidity across fixed-rate Credit Books and integrated yield sources.

• Each Credit Book represents a maturity bucket (30D, 90D, 180D, etc.) with visible fixed-rate levels and curated liquidity depth.

• Borrowers lock collateral and receive instant fixed-rate loans sourced from the vault.

• Curators manage rate ladders, exposures, and asset allocations within predefined risk limits, creating a safe and transparent environment for lenders.

• Automated routing ensures continuous liquidity, predictable rates, and efficient capital deployment.
