Release your album on SentX

Your album goes out as its own token on Hedera. Every copy someone buys is a numbered pressing they own, play, download and can sell on. You keep the recordings, and you take a royalty every time a copy changes hands.

Your masters stay yours Royalty on every resale Storage paid once for the release Free preview from mp3 and wav

Listen to what is out

An album is a token. A copy is a pressing.

When you publish, the album becomes one token on Hedera and you decide how many copies of it exist. Each copy is a numbered serial, the same way a record has a pressing number, and whoever holds that serial owns that copy of the album.

Copies trade on the SentX marketplace like anything else here. The royalty you set sits on the token itself, so it follows every copy through every resale, including the ones you never hear about. Supply is fixed when the token is created, which is the part collectors care about: a run of 200 stays a run of 200.

None of this stops you putting the same record on streaming services. A copy is the thing a listener can hold. Streaming is the thing they play in the car.

The arithmetic is worth doing once. A run of 100 copies at $12 each is $1,200, and at the fraction of a cent a stream pays, that is several hundred thousand plays. The two are not rivals: streaming is reach, and copies are the listeners who want to own what you made.

How the gate works

Full tracks are stored privately and handed out on proof of ownership. Everyone else gets the cover and a 30 second preview of every track you upload as mp3 or wav.

You upload

mp3, wav or flac, up to 60 files in one release. Cover art, titles and track order are yours to set.

We store and prepare

Each track is kept in private storage, fingerprinted, and cut into a 30 second preview starting where you want it to start. Previews come from mp3 and wav. A flac master cannot be cut, so a gated flac track has no preview at all.

The copy is the key

When someone opens the album, SentX checks their connected wallet for a copy of that album token. There is no separate account to create and no list to be added to.

Access follows the copy

Owners get links that work for a few minutes and then stop. Sell the copy on and access moves with it, to the new owner and away from the old one.

What it does not do

This is access control and provenance. It is not copy protection. Anyone who can hear a track can record it, on SentX and on every streaming service, and no platform can honestly tell you different.

What you do get is worth having. The original files are never sitting on a public link. Every copy has an owner you can point to, and every resale pays you. The SHA-256 fingerprint of each track is written into the album metadata on Hedera at launch, so a buyer can check that the file they downloaded is the file you released.

You choose this per track

Gating is a per track setting, not an album setting. A free lead single sitting next to nine gated tracks is a normal way to put a record out, and the builder treats it that way.

Gated
The full track plays only for someone holding a copy. Everyone else gets the 30 second preview and the cover, as long as the master is mp3 or wav.
Public
The whole track plays for anyone who opens the page, owner or not. This is how a lead single works.
A mix
Most releases end up here. One track open so people can hear what they are buying, the rest carried by the copy.

One thing to know before you publish: making a track public is a one way door. You can open a gated track later. You cannot pull a public one back.

What a release costs

Three charges, and they do not all come out of the same place. Storage for the album is paid once and comes off your DreamForge credits. Creating the album token and pressing the copies are paid in HBAR from your wallet, at the moment you do each one.

A four minute mp3 at 320 kbps is about 10 MB. The same track as wav is closer to 40.

What you charge for a copy is entirely yours to set, and it is separate from all of this. The marketplace fee on a sale is listed on the fees page with everything else.

A release does not have to be finished

You can add to an album after it is out. A bonus track, an alternate mix, a live take from the tour. The album builder keeps an upload control on a released album for exactly this, and what you send lands on the album page for people who already bought a copy.

The new file is labelled as added after release, because the fingerprint written on chain at launch covers the release set. The label is worth having. It tells a collector exactly what they got on day one and what turned up later.

Two limits to know. Storage for the extra file is charged when you add it, quoted in the builder first, and owners are not sent a notification about it today. Sending that notification is planned and we are not putting a date on it here.

You can make the record here too

DreamForge, the AI studio on SentX, writes original music from a text description. Vocals or instrumentals, priced per track and paid in HBAR, and what you generate is yours to release.

The album builder has a Generate with AI button for exactly this, and AI made tracks are labelled as such, because a buyer should know. A generated track costs cents rather than studio time, which makes a bonus track or an alternate mix a cheap experiment.

Questions artists ask

How many copies can I press, and can I press more later?

You set the number of copies when the album token is created, and it is fixed from that moment. Nobody can add copies to an existing album, including us. A second run is a new token, the same way a repress is a new pressing, and it reads better to buyers when the title says so.

What does a buyer actually get?

A numbered copy of the album in their wallet. It streams in the browser and downloads as the files you uploaded, the whole album in one go rather than track by track. They can resell the copy on SentX at any time. When they do, access moves to the new owner and stops working for the old one.

How do royalties work?

You set a royalty percentage when the album token is created. It lives on the token itself on Hedera, so it applies to resales on SentX and on any other market that honours it. Payment lands in your wallet in HBAR.

Which audio formats can I upload, and does it matter?

mp3, wav and flac. It matters for one reason: the 30 second preview is cut from mp3 and wav, and we cannot cut one from flac. A gated flac track therefore has nothing a listener can hear before they buy, and the album page labels that row "Owners only" for them. If you want to release in flac, the usual answer is to open one track to everyone as the lead single so there is still something to hear.

Can someone still copy my music?

Yes. Anyone who can hear a track can record it, on this platform and on every other one. Gated delivery keeps the original files off public links and ties playback to ownership. It is access control and provenance, not copy protection, and we would rather say that plainly than let you find out later.

Can I add material after the release?

Yes. Bonus tracks, an alternate mix, a live take. You add it from the album builder and it appears on the album page for anyone holding a copy, labelled as added after release, because the fingerprint written on chain at launch covers the release set only. Two things to know: storage for the extra file is charged when you add it, on top of what the release cost, and owners are not sent a notification about it. Sending that notification is planned, and we are not putting a date on it here.

Do I keep my rights?

Yes. Nothing is signed over to SentX. You confirm at upload that you own or control the recordings, and we store and deliver them on your behalf. You can ask us to stop delivering a release if there is a rights problem to sort out.

What happens to buyers if SentX ever stops running?

The intent is to release keys so owners keep the music they paid for, and that wording is going into the SentX Labs terms of service. Where it actually stands today is worth saying plainly. The route runs off an encrypted copy of the release that is written while the release is processed, and that copy is not produced for every release: very large releases are skipped by the size limit on it. Until it is produced for every release this is an intent we are working towards rather than a guarantee, and we are not attaching a date to it.
