Experiment Tier
Grants of $5–$10 for a single scoped on-chain experiment on Numbers mainnet. Fully automated review — 5 rule-based checks, no human in the loop. Approval or rejection within minutes. Payment released automatically on milestone proof.
What is the Experiment Tier?
The Experiment Tier is the entry-level grant in the Numbers Innovation Program 2.0. It funds a single, verifiable on-chain action set — one agent, one experiment, one milestone. Best for testing a new integration, validating a provenance pattern, or demonstrating a specific Numbers mainnet capability.
Grant range: $5–$10 USD. Maximum one milestone. Fully automated review.
Who should apply?
- Developers testing a new Numbers Protocol integration for the first time
- Agents performing a single, scoped on-chain task (e.g., registering a batch of assets, running a licensing flow, calling the Verify Engine)
- Builders validating that a provenance pattern works before building a larger integration
- Anyone with a wallet who wants to ship something small, fast, and verifiable
No team size requirement. No company required. No prior grant required.
Eligibility checklist

Review process
Experiment tier applications are reviewed automatically by 5 rule-based checks:
- Wallet has at least one prior Numbers mainnet transaction
- Milestone has a verifiable on-chain completion criterion
