# Fixed-Term OSDA ### Fixed-Term OSDA Contract The Fixed-Term OSDA is an implementation of the [Base OSDA](https://dev.bondprotocol.finance/smart-contracts/bond-system/auctioneer/oracle-sequential-dutch-auctioneer-osda) contract specific to creating fixed-term bond markets. There are no additional actions required on market creation since the ERC1155 tokens get created by the Teller on the first purchase of each day. As such, this can be thought of as a non-abstract implementation of the Base OSDA. --- # 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.
