WHY THIS ROUTE

User safety and loss prevention are themes that chain ecosystems and public good funders say they care about, because lost keys are lost users.

ARRIVED LOOKS LIKE

Two applications submitted to real programs (one chain builder grant, one Gitcoin style round) with a public metrics page, within 45 days.

NEXT MOVE · WITHIN THE HOUR

1. List three programs that fund user safety tooling

45 min

Open the Regatta Board and the grant pages of Base, Arbitrum and Polygon. Write down one chain builder grant, one Gitcoin round with a safety or onboarding theme, and one accelerator like Alliance or an a16z CSX style program. Note each deadline and whether existing shipped projects are allowed.

FIRST MESSAGE · EMAIL · TO THE PROGRAM'S GRANTS INBOX

Hi team, quick eligibility question before I apply: Handoff Vault is already live on Base, with a verified heartbeat contract that releases encrypted family instructions after missed check-ins and never stores keys. Do shipped projects qualify for this round, and is user safety tooling in scope? Thank you.

2. Publish a metrics page with honest numbers

40 min

Show vaults created, active heartbeats, guardians invited and the verified contract link. Small numbers are fine; grant reviewers want honesty and direction, not hype.

3. Ask one ecosystem lead for a 10-minute fit check

15 min

Message a grants or developer relations person at your target chain before applying. Ask only whether a safety tool like this fits their current priorities.

FIRST MESSAGE · X DM OR ECOSYSTEM DISCORD · TO A CHAIN'S GRANTS OR DEVREL LEAD

Hi Rafa, I run Handoff Vault on Base: people leave encrypted instructions for family about their wallets, released only after missed check-ins, no keys stored. Before I apply to the builder grant, does user safety tooling like this fit what you are funding this quarter? Happy to share the contract and early numbers.

4. Write and submit the first application

120 min

Use the program's template. Lead with the problem (families locked out of funds), what is live, your numbers, and a 90-day plan with milestones you control. Never claim funding is promised to users.

5. Send a short update to the program 30 days later

15 min

Whether or not you hear back, send a three-line update with new numbers. Reviewers remember builders who keep shipping.
