The challenge

Give testnet participants a reason to build

The chain needed people to learn its tooling, try its private token and NFT standards, and report what they found. A signup or wallet connection could not show that progress. The testnet needed a clear path through increasingly useful tasks, with a way to record both on-chain checks and submitted work.

Claimr’s role

A campaign platform connected to the testnet

Claimr provided the achievement and quest structure, points, recurring tasks and submission workflow. Custom tasks connected the campaign to the client’s chain for faucet, transfer and contract checks, while the operator’s team could review submitted addresses, transaction links and content in the same program.

The Claimr setup

A curriculum with reasons to keep testing

The roughly four-month program combined developer milestones, recurring faucet activity, community achievements and feedback.

Five deployment milestones

A simple contract, ERC-20, ERC-721, a private token and a private NFT gave participants a practical route through the chain’s tooling.

Daily claims and weekly streaks

The custom faucet task checked daily participation. A separate weekly task rewarded a seven-claim streak.

Checks built for the chain

Chain-specific tasks covered faucet receipts, transfers and contract code. Submission tasks covered work that needed a different completion method.

Documentation before deployment

Explorer quests introduced the whitepaper, GitHub, developer portal and block explorers alongside the build tasks.

Feedback and contributions

Written feedback, repository links, tutorials, videos and other content gave the team evidence beyond the on-chain checks.

Continuity from an earlier season

A holding check for the warm-up season’s NFT connected earlier campaign participation to a bonus in the testnet.

The developer journey

Most active participants completed all five deployment tasks

About 76,500 accounts completed at least one deployment task. Of the 104,485 task-active accounts, 60,295 completed all five: a simple contract, ERC-20, ERC-721, a private token and a private NFT. The track introduced the chain’s privacy features alongside familiar EVM standards.

The first task used a contract-code check; later deployment tasks accepted submitted addresses through a review workflow. These counts do not independently establish who deployed each contract or whether contracts were unique across accounts.

58%

Of active participants completed the five-task track

The completed track included both the private token and private NFT deployment milestones.

~8,600

Completed both proxy and upgrade submissions

These accounts completed the proxy-address task and the implementation-replacement transaction task, giving the program a measurable advanced step.

A reason to return

756,000 faucet completions across 47,000 participants

The daily faucet task connected campaign progress to a check on the client’s testnet. About one quarter of faucet participants recorded claims on at least 30 different dates. A separate weekly task recognized seven consecutive daily claims.

The weekly streak task was configured for seven consecutive daily claims.

~11,700

These dates could be spread across the campaign. They do not need to form a consecutive streak.

Participation over time

39% recorded activity at least a month after their first task

Among the 54,346 accounts with at least 30 days of observation, 21,071 completed a task at least 30 days after their first. That is 38.8%, rounded to 39%. Including later arrivals in the denominator gives the original report’s roughly 20% of all active accounts.

At least 7 days after the first task85,45150.5%41.3%
At least 30 days after the first task54,34638.8%20.2%

Activity means a recorded task completion. These measures count activity any time after the threshold, rather than exactly on day 7 or day 30. Observation ends at the last recorded completion on November 11, 2024; total follow-up still varies.

Across 16 full calendar weeks from July 22, weekly participation ranged from about 11,000 to 33,000 accounts. The final week, beginning November 11, was partial.

Work the team could review

Bring code submissions and product feedback into the same program

Participants could share repository links alongside their deployment work and submit written feedback on the testnet. About 20,000 accounts contributed 100,000 completed repository-link tasks; about 62,000 accounts contributed 63,000 feedback task completions.

Completed records can include repeat submissions. Repository totals do not establish distinct repositories, original code or review of every link. Feedback counts do not measure the number of unique issues discovered.

Before the main testnet

An earlier season became part of the next journey

A smaller warm-up campaign brought about 4,400 accounts into Claimr as a hub for quests across six external platforms. It recorded around 11,000 screenshot-proof completions and 980 NFT mint participants.

~980

Completed the warm-up NFT mint task

The earlier season gave participants a collectible that could carry into the next program.

~600

Passed the NFT holding check in the testnet

The testnet checked the same NFT contract for a participation bonus. Ownership at that time does not prove the account earned the NFT in the earlier season.

What to build on

Make the next milestone more useful to the chain

Connect deployments to the submitting wallet

Where chain data allows it, verify the deployer and detect reused contract addresses. Code existing at an address answers a narrower question.

Extend the advanced track

Use the five-task completion as a starting point for proxy upgrades, integrations or an original application. Measure each next milestone separately.

Track useful feedback and later participation

Review feedback quality, group repeated issues and compare participants with a common follow-up window. Those measures can inform the next testnet round.

Methodology

How to read the results

View sources and measurement details

The supplied case study was reconciled with both campaign configurations and their participant exports. Public figures are rounded. Completion records establish campaign status; they do not independently establish unique people, original code or ownership of every submitted deployment.

Cohort and observation window
The main export contains 127,543 distinct participant IDs; 104,485 have at least one completed task. Completion history runs from July 17 to November 11, 2024. The displayed weekly chart starts July 22, excluding an earlier week with four active accounts, and ends with a partial week starting November 11. Some signup records extend to December 2025 without completed activity. Full-export totals are not a strict four-month signup cohort or a count of verified unique people.
Five-contract track
The track counts accounts with a completed task for the simple contract, ERC-20, ERC-721, private token and private NFT deployment steps: 60,295 accounts, or 57.7% of active participants. A total of 76,499 completed at least one of those tasks. The simple-contract task alone has 73,804 participants. Requiring the additional three token/NFT transaction-link tasks reduces the full group to 58,592. The five-task metric does not require every optional repository, explorer or minting step.
What deployment verification establishes
The supplied methodology describes an automatic code-at-address check for the first deployment and review of the later submitted addresses. The export does not establish that every contract was deployed by the submitting account, that contracts were unique across accounts, or that the code was original. Proxy-address submissions have 8,749 distinct participants; upgrade-transaction submissions have 8,644; 8,611 completed both. The original roughly 9,500 proxy figure counts submission records rather than distinct participants.
Daily faucet and weekly streak
The custom daily faucet task contains 755,752 completion-history events from 46,697 accounts. Deduplicating to one account per UTC date gives 755,674 claim dates; 11,655 accounts have 30 or more dates. The weekly task has 17,600 distinct participants and is configured for seven consecutive daily claims. These are recorded task checks, not an independent recount of unique on-chain transactions. Faucet dates are grouped in UTC.
Later activity and eligibility
Activity means any completed task with a history timestamp. Across all 104,485 active accounts, 43,159 (41.3%) have a completion at least seven days after their first, and 21,071 (20.2%) at least 30 days later. The export’s final completion timestamp is the observation cutoff. Restricting the denominator to accounts whose first task was at least seven or 30 days before that cutoff gives 85,451 and 54,346 eligible accounts, respectively. Later activity is 50.5% and 38.8% in those groups. These are any-time-after-threshold measures, not exact-day D7/D30 retention, sessions or causal lifts. Eligible accounts still have differing total follow-up lengths.
Repository and feedback records
Repository-link tasks contain 100,586 completed records from 20,081 accounts. Of these records, 19,912 belong to a simple-contract repository task configured for automatic acceptance; the remainder belong to review-configured tasks. The total is not 100,586 distinct, reviewed or original repositories. The feedback task contains 63,400 completed records from 62,207 accounts; repeat-inclusive history contains 93,933 events. These are recorded submissions, not independently assessed unique ideas.
Review settings and duplicate records
Across all task types, there are 1,731,322 completed records and 12,437 repeated participant/task/quest records. Completion counters match history lengths, and every active account has timestamped history. Submission types account for 1,066,865 records: 1,046,953 in tasks configured for review and 19,912 in an automatically accepted task. Configuration alone does not audit each reviewer’s decision. The source’s blanket claim that all 1.07M submissions were manually reviewed is therefore narrowed.
Warm-up continuity
The earlier campaign has 4,411 accounts, of which 4,357 completed a task. It records 10,968 screenshot-proof completions across six external quest platforms and 979 mint-task participants. The testnet has 607 accounts completing a holding check against the same NFT contract. Holding that NFT does not prove that an account participated in the earlier season, because tokens can be transferred. The report’s roughly 680 returning participants is not reused: available matching methods produce different totals and do not establish a unique-person cohort.
Time-to-finish limitation
The reported completion-speed chart includes 92 accounts whose first accepted completion of all five tasks predates the account creation timestamp. Those records cannot support a valid joining-to-finish duration. The public story omits that chart rather than treating negative durations as unusually fast completions.
