Feature Comparison
Collab Chain
Official Statement Snapshotting
We don't mess with your original data. You upload your official PDF or CSV statements from platforms like DistroKid or SoundExchange, and Collab Chain preserves that file forever. It then creates a deterministic snapshot—a verifiable, tamper-evident digital fingerprint of that exact moment. This means the proof can be verified anytime, by anyone, against that original upload. No guesswork, no "he-said-she-said," just immutable receipts.
Split Confirmation Guardrails
Tired of accidentally forgetting to add your co-writer? Our track-level split status has your back. Each song shows a clear status: Complete, Incomplete, or Not Set. You literally cannot finalize and lock a proof until every single track's splits add up to a clean 100%. It's idiot-proof (in the best way), preventing those "oops, my bad" moments that cost you money and friendships.
Shareable, Read-Only Proof Links
Stop handing out your login deets like candy. Once a proof is locked, you can generate a secure, read-only link. Send it to your manager, your label, your lawyer, or your collaborator's sketchy cousin. They can view the entire verified proof summary without needing an account and without any ability to edit a single thing. It's transparency without the vulnerability.
Supporting Evidence Lockers
Sometimes platforms are stingy and won't let you download a proper statement. No sweat. You can upload screenshots as Supporting Evidence. We clearly label these as "Not an Official Statement" so everyone knows the deal, and we never use them for calculations. They live in a separate section of the proof for extra context, keeping your audit trail legit and organized.
LuxSign
Luxembourg Lockdown Hosting
This is the big one. Every single document you upload is stored on secure servers physically located in Luxembourg. This isn't just about speed; it's the ultimate privacy move. By keeping everything within the country's borders, LuxSign guarantees full compliance with GDPR and Luxembourg's own strict data protection laws right out of the gate. Your sensitive contracts aren't bouncing around the global internet; they're chilling in a digital fortress in the heart of the EU. It's peace of mind you can't put a price on.
eIDAS SES Legally Valid Signatures
Stop worrying if your digital signature will hold up in court. LuxSign provides Simple Electronic Signatures that comply with the EU's eIDAS regulation (910/2014). This means your signed contracts are legally admissible and valid for most business transactions across all 27 EU member states. It's the legal muscle behind the digital pen, making your online agreements as binding as the old wet-ink version, but without the hassle.
Drag, Drop, and Send Workflows
Signing is stupid simple. Upload your PDF or Word doc, then literally drag and drop signature, date, and initial fields exactly where you need them. Need four people to sign? Add them all. You can choose if they sign all at once (parallel) or in a specific order (sequential). Hit send, and the platform automatically fires off personalized email invites to each signer. You can just kick back and track the progress in real-time as everyone does their part.
All-Access Audit Trail
For compliance nerds and detail-oriented bosses, this feature is a godsend. Every action on a document is meticulously logged. We're talking timestamps, IP addresses, and full signer info for every view, click, and signature. This creates a tamper-proof record of the entire signing journey. If anyone ever questions the process, you have a crystal-clear, verifiable paper trail (a digital one, obviously) to prove exactly what happened and when.
Use Cases
Collab Chain
The Producer Securing Their Points
You just produced a fire beat for an artist. Instead of trusting a verbal agreement that gets fuzzy later, you use Collab Chain. When their distributor statement drops, you get them to upload it, confirm your 5% producer points, and lock the proof. Now you have an unchangeable record to send to your manager, ensuring you get paid what you're owed, every single quarter, no questions asked.
The Band Avoiding Internal Drama
Your band has four members with different writing contributions across an EP. Royalty time is usually a spreadsheet nightmare. With Collab Chain, one member uploads the statement, and you all confirm the pre-agreed splits per song right in the platform. Once locked, everyone gets a shareable link to the same verified truth. No more side conversations or accusations—just one source of financial truth for the whole squad.
The Songwriter Building a Publishing Portfolio
As a songwriter, your credits are your resume and your paycheck. Collab Chain lets you gather every royalty statement that features your work, confirm your writing splits, and lock them into a verifiable portfolio. When it's time to negotiate with a publisher or a new collaborator, you can show proven, historical earnings and credit accuracy, boosting your leverage and professional rep.
The Manager Organizing a Roster's Paperwork
Managing multiple artists means a flood of statements from different sources. Collab Chain becomes your central command hub. You upload each artist's statements, work with them to confirm splits, and lock proofs for every release. This creates an organized, verifiable archive for your entire roster, making accounting, audits, and settling disputes between collaborators smooth and professional.
LuxSign
Freelancer Closing Deals Fast
You're a designer, consultant, or developer. You just finished a killer proposal for a new client. Instead of attaching a PDF and hoping they print-sign-scan-email it back (lol, never happens), you drop it into LuxSign. Drag a signature field to the bottom, send it via email, and boom—they can sign on their phone in 30 seconds. You look professional, you get paid faster, and you avoid the endless email ping-pong. It's a solo-preneur game changer.
HR Onboarding New Team Members
HR folks, feel the pain of onboarding paperwork no more. Offer letters, NDAs, policy agreements—you can bundle them all into a seamless digital packet. Set up a sequential workflow where the candidate signs the offer first, then HR signs, then it's automatically filed. Everything is encrypted, legally sound, and stored securely in your LuxSign workspace. No more lost forms or chasing down physical signatures on day one.
Small Business Managing Client Contracts
Running a small agency or firm? You're constantly sending out service agreements, project scopes, and approval forms. With LuxSign's Premium plan, you can save these as templates. Next time you need a contract, just fill in the client's details, add signature fields, and send it to multiple stakeholders at once. The audit trail keeps everything above board, and the Luxembourg hosting keeps your clients' data super secure, which is a major trust signal.
Enterprise Legal & Compliance Teams
For larger companies, especially in regulated industries, compliance is non-negotiable. LuxSign's Business tier offers the heavy artillery: full API access and an SDK for baking e-signatures directly into your existing CRM, document management, or ERP systems. Add custom branding so every signing experience screams your company name, and use collaboration workspaces to manage complex, multi-departmental signing processes with strict access controls and a unified audit log.

Frequently Asked Questions
Collab Chain FAQ
Does Collab Chain pull my live streaming data or send payments?
Absolutely not. We are not a distributor, a payment processor, or a data scraper. Collab Chain works entirely off the official statements you choose to upload. We don't connect to your streaming accounts to pull live data. We take the paperwork you already get, help you structure it, and turn it into a verifiable proof. You handle payments through your normal channels; we just make sure everyone agrees on the numbers.
What if a platform doesn't let me download a statement?
We got you. While official exports (PDF/CSV) are the gold standard for creating the most robust proof, some platforms are annoying. For those, you can upload screenshots as "Supporting Evidence." These are clearly labeled as not being official statements and are never used for calculations. They sit alongside your official docs to provide extra context, keeping your paper trail as complete as possible.
Can someone alter a proof after I share the link?
Nope, that's the whole magic. Once a proof is "finalized and locked," it's set in digital stone. The system runs server-side validation to check everything, then creates a tamper-evident record. The shareable link you send out is strictly read-only. Recipients can view the verified snapshot but cannot edit, alter, or delete any part of it. The original uploaded files are also preserved forever.
What happens if I make a mistake while setting up splits?
No stress, you can't accidentally lock it in wrong. The platform won't let you finalize a proof until every track's splits are confirmed and add up to 100%. You can edit and adjust all you want during the setup process. Only when everything is complete can you hit the finalize button. And if something goes wrong during that final step, a transactional rollback ensures no partial or messed-up records are saved.
LuxSign FAQ
Is a LuxSign signature really legal?
For real! LuxSign provides eIDAS-compliant Simple Electronic Signatures (SES). Under EU Regulation 910/2014, these signatures are legally admissible and valid for the vast majority of business and personal transactions across the entire European Union. Think sales contracts, NDAs, service agreements—you're totally covered. For super high-stakes stuff like property transfers, you might need a Qualified signature, but for 99% of biz, you're golden.
Where exactly is my data stored?
This is the core of LuxSign's vibe. Your documents are stored exclusively on secure servers located within Luxembourg. They never leave the country. This isn't just about good security; it's the key to guaranteeing automatic compliance with GDPR and Luxembourg's own top-tier data protection laws. Your data gets a Luxembourg passport and never has to travel.
Can multiple people sign the same document?
Absolutely, and you get to call the shots on how it goes down. You can add up to 4 signers per document on the Premium plan. Need everyone to sign at the same time? Use parallel signing. Need the CEO to sign before the intern? Set up a sequential workflow. The platform guides each signer through their part automatically with email notifications, so you don't have to play project manager.
What if I need to sign something on my phone?
No sweat! LuxSign is fully mobile and tablet-ready. The interface is optimized for touch, so you can easily draw your signature with your finger or stylus. Whether you're commuting, between meetings, or just away from your desk, you can review and sign documents securely from anywhere. Getting documents signed doesn't have to wait until you're back at your computer.

Alright, let's break it down. LuxSign is that super-compliant e-signature platform from Luxembourg that's all about keeping your digital paperwork legally binding across the EU. It's in that productivity and management category, basically your go-to for signing stuff without the printer drama. So why are people even looking elsewhere? It's the usual suspects.

Think about your actual needs. Do you really need that top-tier EU-wide legal validity, or is a basic signature enough?
