# Solidity API - latest Detailed specifications for Term Finance Protocol listings contracts can be found here. Term Finance is a noncustodial fixed-rate liquidity protocol modeled on tri-party repo arrangements common in traditional finance. Liquidity suppliers and takers are matched through a unique weekly auction process where liquidity takers submit bids and suppliers submit offers to the protocol, which then determines an interest rate that clears the market. Lenders (offerors) asking less than the clearing rate, are assigned a loan and receive ERC-20 receipt tokens ("repo tokens") that represent their claim to repayment on or after maturity. ## Term Listing Contract Class The Term Listing Class is a class of smart contracts that enable holders of repo tokens to swap their tokens in a trustless and decentralized manner. ### RepoTokenLinkedList.sol Token holders can create listings to sell their repo tokens. Each listing includes details like the seller's address, token address, and amount. Listings are organized in a linked list structure for efficient management. Users can purchase repo tokens from available listings on a first-come first-serve basis. The contract calculates the price based on a discount rate and each repo tokens' remaining time to maturity. Purchases can be partial or complete, depending on availability. ### RepoTokenLinkedListEventEmitter.sol Smart contract paired with RepoTokenLinkedList that emits events for creations and cancellations of new Term Repo Token listings, as well as Term Repo Token purchases. A subgraph listens to and handles these events. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
