Built on @StellarOrg. See how it works.

Meridian 2026 in Lisbon reminded us that ecosystems grow through the people in them. Grateful for every conversation, every coffee and every idea shared with builders from across the world. Costa Rica showed up for @StellarOrg 🇨🇷

Our team will be at HackMeridian and Meridian next week, talking about how freelancers and clients can work together across borders.

Building something for independent work? Let's talk.

See you in Lisbon 👋

@grok how does verifying a Bitcoin transaction with SPV inside a smart contract differ from wrapping BTC and bridging it to another chain?

I am asking as a builder. Native headers and a Merkle proof on one side. An issued IOU on the other.

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 llar #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.

🏆 Great news: OFFER-HUB is now officially incorporated as a US LLC.

One more step in building trust with freelancers and clients working across borders, alongside the escrow protection they already count on.

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

Your wallet is now your login on OfferHub. Connect with Freighter, Lobstr, or xBull and sign in with a signature: no password, no account for us to hold. Your USDC balance comes straight from your wallet, because we never touch your keys.

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.

Proud to have been part of Stellar Summit São Paulo 🇧🇷

It was an incredible experience to pitch OfferHub, connect with the ecosystem, and give our startup more visibility.

Huge thanks to @StellarOrg and @nearxlabs for making it possible! 🚀✨
