# DRC205 The [DRC205](https://github.com/iclighthouse/DRC_standards/tree/main/DRC205) standard defines swap transaction record data structures, scalable storage interfaces, and swap application storage and query specifications. #### **Features** * **Universally Applicable**: Designed for multiple spot swap Dex, it efficiently stores transaction records, ensuring compatibility across various platforms. * **Highly Scalable**: It scales automatically and infinitely in line with the storage capacity limits of canisters. Utilizing Bloom filter technology, it addresses the storage constraints of index canisters, facilitating easy record retrieval. * **Transparent**: The transaction records stored are openly accessible and queryable, upholding the transparency ethos of decentralized exchanges. --- # 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.
