Hey Product Hunt! 👋
I built reserveBTC.io to solve a simple but critical problem: how can businesses prove they actually hold Bitcoin — without asking users to trust them?
With reserveBTC, any company can publicly verify their BTC reserves using a secure, non-custodial widget. No logins, no middlemen, no KYC — just pure onchain proof.
I’d love your feedback!
➡️ What use case do you think this helps most?
➡️ Should we expand support beyond Bitcoin?
Ask me anything in the comments — I’m here all day! 🙌

Here’s one of our key use cases — for content creators.
Bloggers, influencers, and online educators often say they believe in Bitcoin.
By publishing their BTC reserves with our widget, they turn reputation into trust.
It’s simple, transparent, and on-chain.

Make your Bitcoin reserves public with ReserveBTC.io
Because proof builds trust — and trust builds everything else.
When you publicly verify your BTC holdings, you’re not just signaling transparency — you’re engineering confidence at every level of your business or project.
Here’s what that proof unlocks:
✅ Reputation Boost — Stand apart in a crowded space by showing you’re not just talking Bitcoin… you’re holding it.
✅ Guarantee Obligations — Whether you run a fund, DAO, or DApp — verified reserves reduce doubt and eliminate guesswork.
✅ Brand Credibility — Add a Bitcoin badge of trust to your brand. It works like social proof — but stronger.
✅ Partner Confidence — Business partners and collaborators trust you more when they can see your financial signal on-chain.
✅ Deal Assurance — When real BTC backs your offer, every negotiation starts stronger.
✅ Meme Token Legitimacy — Launching a token? Back it with public BTC to prove you’re not a joke.
✅ DAO Seriousness — DAOs with public reserves signal long-term intention, not just hype.
✅ Public Savings Wallet — Open a BTC piggy bank in full view. Great for community-driven projects.
✅ Withdrawal Guarantee — Show that user funds are always redeemable. Kill FUD before it starts.
✅ Trading Collateral — Market-makers and investors know you’re solvent. That unlocks more volume.
✅ Support for Independence — Bitcoin reserves reflect economic autonomy — for creators, companies, and sovereign entities.
✅ Signal Growth Intent — Proof of capital signals plans, not promises.
✅ Fund Development — Fundraising? Verified BTC shows you’re ready for responsibility.
✅ Capital Protection — Holding BTC = long-term skin in the game.
✅ Financial Sovereignty — Don’t rely on banks. Rely on Bitcoin.
✅ Inflation Hedge — BTC speaks for itself, on-chain.
✅ Asset Diversification — Proof that you’re hedged — and smart about it.
🔁 Plus:
— Investor trust 🟢
— Liquidity assurance 💧
— Strategic positioning ♟️
— Blockchain alignment ⛓️
— Risk mitigation 🛡️
— Operational financing 🔄

💡 ReserveBTC.io doesn’t hold your funds. It just proves you have them — publicly, cryptographically, and instantly.
👉 Add the widget. Prove it. And unlock the power of transparent reserves.
I’m founder of ReserveBTC.io, and I’m excited to share what we’ve been building: a fully non-custodial, trustless, and cryptographically verifiable way to prove Bitcoin reserves — and unlock their use in DeFi.
🧬 Introducing rBTC-SYNTH
rBTC-SYNTH is a soulbound, auto-burning synthetic token that represents live Bitcoin reserves — without requiring users to move or lock their BTC with a third party.
How it works:
• Users verify BTC ownership by sending a unique checksum (e.g. 0.001492 BTC) to a unique BTC address generated for them.
• Once the checksum is confirmed on-chain, a synthetic token is minted 1:1 on Ethereum: 1 BTC = 1 rBTC-SYNTH.
• The token is:
• Non-transferable (soulbound)
• Auto-burned if the BTC is moved
• Bound to the user’s ETH address, not to liquidity
This gives users a DeFi-native proof-of-hold, without ever giving up control of their Bitcoin.
🔍 Why it matters:
Most Bitcoin-on-Ethereum models rely on bridges, wrapped tokens, or custodial risk. We don’t.
rBTC-SYNTH:
• Enables BTC holders to farm yield, vote in DAOs, and verify reserves without moving BTC
• Solves fake reserve risk, double-counting, and token resale fraud
• Leverages Merkle Proofs, Chainlink Oracles

We’ve made major progress in turning Bitcoin reserves into a usable, verifiable onchain identity:
✅ Launched the ReserveBTC Widget – A no-custody Proof-of-Reserve tool that allows businesses and users to prove BTC holdings publicly, without moving coins.
✅ Implemented BTC signature-based verification – No KYC or intermediaries. Everything works through unique checksum deposits and BTC-native proofs.
✅ Deployed the rBTC‑SYNTH Testnet Contract – A soulbound, synthetic token minted 1:1 upon successful reserve verification and automatically burned if BTC leaves the wallet.
✅ Live integration with front-end UI – The widget now supports QR generation, dynamic address assignment, and full signature tracking.
