Bonded
Lying costs money
Every claim puts up a USDC bond. A claim that turns out to be false loses its bond to whoever proved it wrong — so claiming work you didn't do is a bet you expect to lose.
Milestone grants, settled on Base
Fund the work.
Not the paperwork.
GrantLane escrows a grant up front and releases it milestone by milestone. A builder claims a milestone with evidence and a bond; if nobody disputes the claim in time, it pays out. Lying is expensive, and nobody has to approve every milestone by hand.
The problem
Grant money moves at the speed of somebody's inbox.
Review is a bottleneck
Every milestone waits on a human to read it, agree it counts, and remember to trigger a transfer.
Or it's paid on trust
The alternative to slow review is paying on someone's say-so — and then nothing stops a claim that the work is done when it isn't.
Rounds attract scripts
Open applications get farmed. Filtering them is manual, and the filtering falls on the same overloaded reviewer.
How it works
Four steps. Nobody approves a milestone by hand.
- 01
Someone applies
A pitch, a live site, a public repo, and how they'd split the work into milestones. A Selfie Check runs before submit, so the queue is builders and not scripts.
- 02
The granter escrows
They read the proposal, adjust the scope they're willing to fund, and lock the whole grant on Base up front — along with a hash of the milestone terms, so the terms can't be edited later.
- 03
The builder claims
When a milestone is done they verify they're human again, publish their evidence, and claim the milestone on UMA with a small USDC bond.
- 04
It pays unless challenged
The claim is open to dispute for a set window. If nobody disputes it, it pays out. If someone does, UMA decides — and whoever was wrong loses their bond.
What makes it different
Three things the escrow enforces, not promises.
Disputable
Anyone can check, anyone can challenge
The evidence is public, linked from the claim and hashed on-chain. The granter — or anyone — can dispute inside the window, and UMA's optimistic oracle settles it. No admin key can release the money, or hold it back.
Human
A person, not a farm
World ID Selfie Check gates the three moments that matter — applying, claiming a milestone, and changing where the money lands. Each uses a different action, so a proof farmed at one gate is worthless at the others.
Built on
Each piece does the one thing it's best at.
- Base + UMA
- Settlement. The escrow lives on Base; each claim is an optimistic assertion on UMA — bonded, public, and open to dispute.
- Chainlink CRE
- Upkeep. A cron workflow finds claims whose window has closed and settles them, following Chainlink's Automation-to-CRE path.
- World ID
- Personhood. Selfie Check proves a live human without revealing which one.
Escrow it once. Let the work release it.
Applications take a few minutes and a Selfie Check. Grants run on Base Sepolia testnet.
