Public budget transparency,
verified on Solana
Built and validated in Indonesia's national hackathon. Ready for any institution that handles public money — including foreign aid.
The trust gap is everywhere
Wherever money flows through institutions, accountability is slow, manual, and easy to manipulate. Donors and citizens are left guessing.
Government budgets
Annual reports arrive months late. Spending data lives in PDFs that can be amended. Citizens can't verify how their tax money is actually used.
NGOs & foundations
Donors trust quarterly impact reports. When something feels off, there's no real-time way to audit how funds were spent — only the next report cycle.
Foreign aid
Agencies send billions across borders, then rely on recipient governments' own reporting. Tracking the last mile of aid is a chronic, expensive problem.
How OpenBudget works
Every spending milestone is recorded on the Solana blockchain. Citizens and donors verify the real transaction, in real time, without trusting any single party.
Institution registers project
Set budget, milestones, and authorized signers. All metadata stored on-chain.
Publishes to Solana
A blockchain account is created. From here on, the project record is immutable.
Releases funds per milestone
Each spending milestone is signed and timestamped on-chain with a proof link.
Anyone verifies in real time
Citizens, donors, auditors query the chain directly. No quarterly reports needed.
Hybrid architecture: The blockchain is the single source of truth. A PostgreSQL cache makes browsing fast. If the cache ever drifts, the system automatically heals from on-chain state.
Battle-tested, not vaporware

Where this fits next
OpenBudget's architecture is institution-agnostic. The same trust primitive applies anywhere public money flows.
National & municipal budgets
Any government wanting tamper-proof spending records that citizens can verify directly.
Foundations & NGOs
Donor-funded organizations giving stakeholders real-time visibility into program spending.
Religious institutions
Mosques, churches, temples, zakat / waqf bodies handling donations — full transparency restores donor trust.
Universities & research grants
Grant recipients reporting milestone spending to funding bodies in real time, not via annual PDFs.
Foreign aid transparency
Aid agencies send billions across borders annually, then rely on recipient governments' own quarterly reports. There's no real-time, tamper-proof way to verify the last mile of aid spending.
OpenBudget was built and validated by an Indonesian government hackathon — a recipient country's own technologists endorsed it. An aid agency can deploy the same primitive to verify exactly how its funds are spent by recipient ministries, in real time, without trusting periodic reports.
Bring this to your institution
We're looking for the next institution to deploy OpenBudget. If your organization handles public money — a government, foundation, NGO, or aid agency — get in touch.
Currently on Solana devnet. Mainnet deployment available on request for committed pilots.
