Summary: Astaria is bilateral credit machinery built on Starport. The useful part is not generic NFT-lending branding; it is pairwise matching, signed intents, refinance-or-recall flow, and lender control over collateral and terms.
What it does:
Lets borrowers and lenders publish off-chain signed intents for loans with predetermined collateral, size, and rate constraints
Uses 24-hour inclining-rate auctions where loan APY rises continuously until a counterparty fills the intent or it expires
Supports ERC-20, ERC-721, and ERC-1155 collateral and debt pairings rather than depending on a narrow governance-curated listing set
Uses a recall mechanism where an existing lender can seek refinancing after 24 hours, and if no replacement lender appears the original lender can seize collateral after a failed recall
Builds the application on Starport, a lending kernel that separates agreement enforcement and collateral custody from higher-level lending experiences
Publishes audits, deployment links, and API documentation as part of a reasonably complete protocol surface
Key claims:
The official introduction says Astaria is a lending protocol supporting any ERC-20, ERC-1155, and ERC-721 assets, and that it enables fixed-rate loans with unlimited durations
The docs say intents are live for 24 hours and that APY increases continuously from 0% to a predefined amount until a lender accepts the terms
The introduction argues Astaria avoids the socialized risk of pooled lenders because users choose exactly what collateral their assets are lent against instead of joining a shared pool
The same page says Astaria removes the need for an asset-listing process and uses recall/refinancing design to eliminate reliance on oracles
The recall docs say a lender can send a loan to recall after 24 hours, borrowers may still repay with no penalty during recall, and failed recall lets the original lender retrieve collateral
The Starport docs say Starport is a kernel for composing lending protocols, not itself the full lending app, and that it operates around borrowers, lenders, and fulfillers
The audits page says Astaria underwent formal verification and multiple complete audits with Certora, including a Starport lending-kernel audit
The public GitHub organization describes Astaria’s mission as “instant liquidity for any on-chain asset” and includes repos for astaria-core, v1-core, starport, and starport-whitepaper
Whitepaper: First-party papers from the Astaria whitepaper repo are now saved in this corpus as ../whitepapers/starport-whitepaper.pdf, ../whitepapers/starport-whitepaper.tex, ../whitepapers/astaria-v1-whitepaper.pdf, and ../whitepapers/astaria-v1-whitepaper.tex. The Starport paper covers the reusable lending kernel, while the Astaria v1 paper covers the oracleless intent-based application layer; see ../whitepapers/astaria-primary-sources-2026-05-08.md and ../projects/starport.md.
