File Exchange Description

1. The app uploads the file to IPFS, registers the received ipfs url (the hash value starting with Q is important) to the 3 seconds club server, and receives a unique file ID.
2. Register a unique file ID in the OTC file transaction contract. When transacting files, you must first upload the file id to the opened OTC, and you can check the authenticity of the file on the 3 seconds club server to see if the file is uploaded to the file id.
3. When the transaction is completed, the person who purchased the file can execute the transaction completion api on the server to receive the actual file url path (the server confirms whether the transaction has been completed at this point and delivers the actual url to the contract). At the time of transaction completion, the file seller will receive tokens.
