Retrieve File from IPFS

WHAT IT DOES

Retrieve File from IPFS enables you to retrieve files from the InterPlanetary File System (IPFS) using a Content Identifier (CID). IPFS is a decentralized storage network used extensively in blockchain applications for storing NFT metadata, dApp assets, and decentralized content. This tool takes an IPFS CID, fetches the file from a public IPFS gateway, and displays file information including name, size, and a direct download URL. This is essential for developers, creators, and users who need to access files stored on IPFS for verification, inspection, or downloading. The tool provides clear output showing the CID, file name, size, and gateway URL.

HOW TO USE

Connect your wallet using the BGWallet connector (required for context). Enter an IPFS CID in the input field (e.g., "Qm..."). Click "Retrieve File" to fetch the file from IPFS. The tool displays the CID, file name, file size, and a shareable gateway URL. You can click "Download File" to open the file in a new tab or download it directly. The result includes a detailed breakdown showing the file details and retrieval status.

TECHNICAL MECHANISM

This tool implements IPFS file retrieval using a public IPFS gateway. The retrieval process: (1) the CID is validated as a string; (2) the file is fetched from the gateway using the CID; (3) the response headers provide content-length and content-type; (4) the file information is displayed to the user. The tool uses the https://ipfs.io/ gateway for demonstration purposes. In a real implementation, users could configure custom gateways. The file is retrieved directly from the IPFS network via the gateway. All retrieval is performed in the browser with no data sent to external servers beyond the gateway request.

WHAT IT CANNOT SEE

This tool cannot verify that the file exists or is available on IPFS—it only attempts to retrieve it. It does not support retrieval from private IPFS networks or encrypted files. The tool cannot guarantee the file's availability or integrity. It does not support custom IPFS gateways or API endpoints; the default gateway is used. The tool cannot retrieve files larger than the configured IPFS gateway limit. It cannot detect if the file has been modified or tampered with after retrieval. The tool does not support file pinning or persistence verification. It cannot guarantee that the CID corresponds to the expected file content.

PLEASE NOTE

This tool is designed for developers and users working with IPFS file retrieval. IPFS CIDs are content-addressed identifiers that uniquely identify file content. The gateway URL allows access to the file via HTTP. The tool uses a public IPFS gateway (ipfs.io) for demonstration purposes. For production use, consider using dedicated gateways or pinning services. Always verify the retrieved file content against the expected CID. The tool is read-only and does not require any on-chain interactions. The retrieval is performed via a public IPFS gateway and may have file size limits. The tool is intended for testing, development, and educational purposes.
