Overview
EchoUploader is a file storage tool that keeps a tamper-proof receipt of every file you upload. You drag a file in, the tool saves it to a peer-to-peer file network called IPFS (a system where many computers share the file instead of one company's server), and it writes a small fingerprint of the file to the Cardano blockchain1. Anyone can later check that fingerprint to confirm the file existed at that time and has not been changed. EchoUploader is one of four products inside the EchoForge suite, alongside EchoCert, EchoDash, and EchoVote.
The parent company, EchoForge, describes itself as a maker of infrastructure tools for the Cardano ecosystem2. EchoUploader is the suite's storage product.
Key Features
- Files stored on a shared network. Uploads are pinned to IPFS through Pinata, so a file stays reachable through the network even if any one host goes offline3.
- On-chain proof an upload happened. Each upload writes a small record to the Cardano blockchain in a standard format, so the file's fingerprint, time, and uploader can be checked against the public ledger later4.
- Built-in file Look Up. A separate tool on the EchoUploader site lets anyone paste a file's fingerprint and confirm whether that exact file was uploaded through EchoUploader and recorded on Cardano1.
- Prices in dollars, paid in ADA. Three subscription tiers are offered: Pioneer at twenty dollars for five gigabytes, Architect at forty-five for fifty gigabytes, and Galactic at one hundred eighty for five hundred gigabytes. The ADA amount you actually pay is set live by a price feed from Charli3, with CoinGecko as a backup1.
- Choose your own wallet. Wallet sign-in is handled through MeshJS, an open-source Cardano library that supports the most common Cardano browser wallets, so you are not locked into one brand5.
What to Expect
EchoUploader is a focused single-purpose tool, closer to a developer utility than a polished consumer app. You connect a Cardano browser wallet, pick a subscription tier, pay in ADA at the live exchange rate, and start uploading. Each upload returns a record you can look up later on the site to confirm it is on the Cardano blockchain. EchoID holders, where EchoID is a separate identity product EchoForge is building, get a discount that scales with the tier.
A few things to weigh before signing up. The footer links to Terms of Service, Privacy Policy, and Cookie Policy do not lead anywhere yet, and EchoForge has not published a business address or jurisdiction on its site. No source code has been published for EchoUploader. For a tool that holds your files and accepts paid subscriptions, those gaps are worth weighing against the appeal of the on-chain receipts.
Readers looking at the tool today should also check the live progress checklist on the EchoUploader product page before committing. The checklist covers IPFS upload, the subscription system, oracle pricing, on-chain payment verification, the file registry and Look Up tool, EchoID discounts, wallet persistence, mainnet deployment, batch uploads, and public sharing links6. The Mainnet deployment line is the signal that the product has moved past test-network status. Until that line is marked complete, the live app runs against a Cardano test network, so any uploads you make should be treated as test data rather than long-term records6. EchoForge says it is also building three companion products: EchoCert for verifiable credentials, EchoDash for a project dashboard, and EchoVote for governance. Each is at its own readiness stage.
