DeBOR

DeBOR (Decentralized Benchmark Oracle Rate) is the missing reference rate for DeFi. Traditional finance prices every mortgage, bond, and derivative off benchmark rates like SOFR. DeFi has $50B+ in lending TVL but no aggregated standard. Each protocol publishes isolated rates with no composite benchmark, no term structure, and no volatility metric. Institutions cannot assess DeFi yields against a standard, and the $500T+ interest rate swap market has no DeFi equivalent.

DeBOR fixes this. It reads live lending rates from 9 protocols (Aave V3, Compound V3, Spark, Morpho Blue, Moonwell, Benqi) across 6 mainnet chains, weights them by TVL from DeFiLlama, and publishes benchmark rates on-chain every 30 minutes via Chainlink CRE. It covers 5 assets (USDC, ETH, BTC, DAI, USDT) from 43 individual rate sources.

On top of the oracle, DeBOR includes: an interest rate swap protocol (the first DeFi IRS, with ERC-721 tokenized positions and autonomous CRE settlement), cross-chain relay via CCIP to 3 L2s, AI risk assessment with DON consensus that can autonomously block swaps when risk is critical, an adaptive lending consumer that adjusts rates and collateral in real time, a risk engine with VaR/CVaR/HHI/Basel stress tests, and credit-gated premium API access.

Three components:

1. Smart Contracts (Foundry, Solidity 0.8.24): 13 contracts including DeBOROracle (stores benchmarks), DeBORSwap (ERC-721 IRS positions), DeBORCCIPSender/Receiver (cross-chain relay), DeBORAIInsight (on-chain risk metadata), DeBORPaymentGate (credit-gated access), and DeBORConsumer (adaptive lending). Uses OpenZeppelin and Chainlink CCIP libraries. 146 tests.
2. CRE Workflow (TypeScript, @chainlink/cre-sdk): 10 handlers orchestrating the full pipeline. Reads 43 rate sources from 6 mainnet chains via EVM reads, fetches TVL weights, computes benchmarks, writes to 5 oracles on Sepolia, settles swaps, runs risk analysis, calls Groq LLM for AI consensus, validates via HTTP cross-checks, and compares against SOFR/EFFR from the NY Fed API.
3. Frontend (TanStack Start, React 19, wagmi, RainbowKit): 10 pages covering dashboard, asset detail, swap, cross-chain, compare, risk, AI, payment, pipeline, and methodology. 17 custom hooks for on-chain data. Deployed on Netlify.
