Privacy on Writz, without the slide version.
We have ZK work on testnet. We will not say your position is hidden on mainnet until that is the product you can click.
🏆 Offer-Hub's Tranche #2 has been approved and paid out by the Stellar Community Fund: 110,396.79 XLM.
Delivered: client-side escrow signing, BlindPay fiat payouts to local banks (BR, MX, AR, CO), automated off-ramp with retries.
Next: Tranche #3, mainnet launch.
Thank you @StellarOrg @BuildOnStellar #StellarCommunityFund

Wrapped BTC is an IOU.
A good IOU is still an IOU. An issuer holds BTC and mints a token on another chain.
Writz is a script on Bitcoin and a verifier on Soroban. The collateral never becomes a token named BTC.

How the BTC gets locked.
A P2WSH output on Bitcoin. Two paths out. Only two.
Path A: you and the protocol sign.
Path B: the timelock expires, you sign alone.

Spent some time as part of the Open-Source commitment helping the team at @offerhub_ draft the Trustless Work section of their docs; escrow lifecycle, state machines and the whole flow.
Nothing sharpens your own understanding like having to explain it clearly.

Bitcoin SPV inside a Soroban contract, in one picture.
The contract does not call a Bitcoin node.
The caller brings 6 headers, a Merkle proof, and the raw transaction.
The contract checks the math.

Your Bitcoin never leaves Bitcoin. Your loan, nobody sees.
Real BTC collateral, verified on-chain via SPV. Zero custodians. ZK-private positions.
Your keys. Your coins. Your loans.

Big milestone for Sub Rosa! 🔥🌹
We just shipped our first real product integration with @offerhub_ 🥳
This is the first step toward making Sub Rosa more than a standalone protocol - turning it into infrastructure that other products can actually plug into and use
More integrations coming soon 👀
Here’s what it looks like in practice: wallet connect to balance check, all on testnet.

Excited to announce our pilot collaboration with Sub Rosa!
Freelancers can now submit private, sealed proposals that stay hidden until the deadline, then get revealed simultaneously before the client selects a provider. A fairer process, no bias, no early-mover advantage.
Sub Rosa x Offer Hub pilot is live! 🤝
Freelancers can submit private proposals for jobs, keep them sealed until the deadline, then reveal together before the client selects a provider

Huge thanks to @StellarOrg and @nearxlabs for making it possible! 🚀✨
We just submitted OfferHub to the Stellar Community Fund.
Here's what we're building a freelance marketplace where payments are guaranteed by code, not by trust.
