Builder activity receipt
OPN Builder Receipt is a small receipt-based contract deployed on OPN Chain. It lets a wallet issue a native OPN builder receipt and stores that receipt as a transparent on-chain activity record.
The idea is to create a simple proof layer for builder-related funding, deposits, or ecosystem activity without relying only on off-chain notes.
Why it makes sense
Builder programs often involve small actions: funding, submitting, supporting, testing, contributing, or recording participation. A receipt model is useful because it creates a readable record of value and activity linked to a wallet.
This first version keeps the scope narrow: issue a receipt, store its value, track whether it was settled, and make the record readable.
Contract behavior
- The user calls
issueBuilderReceipt()and sends native OPN. - The contract creates a builder receipt for that wallet.
- Each receipt stores amount, issue time, and settlement status.
- The contract tracks receipt value by user.
- It also tracks total receipt value and builder receipt event count.
settleBuilderReceipt()is included for closing a receipt later.- Read functions expose receipt records by wallet.
OPN Chain proof
The contract was deployed on OPN Chain during the Season 1 submission window. A live issueBuilderReceipt() transaction was executed after deployment, so the submission includes both deployment proof and real interaction proof.
Roadmap

What ships next.
The builder's own next-quarter plan. Use it to gauge follow-through and ambition.
Current submission
The first version of OPN Builder Receipt focuses on a simple builder activity receipt:
- Deploy the builder receipt contract on OPN Chain.
- Test the
issueBuilderReceipt()function with native OPN. - Store receipt amount, issue time, and settlement status on-chain.
- Track receipt value by user.
- Track total receipt value and builder receipt event count.
- Submit the build for Season 1 review.
Next step
The next step is to add a small receipt dashboard:
- Add wallet connection.
- Let users issue builder receipts from a web page.
- Show receipt records for the connected wallet.
- Separate open and settled receipts.
- Add explorer links for receipt transactions.
Product expansion
After the basic interface, the builder receipt model can support more ecosystem use cases:
- Add named builder receipt records.
- Add receipt categories for grants, rewards, testing, submissions, or community support.
- Add ERC-20 receipt support.
- Add public receipt pages for transparent verification.
- Improve event indexing for dashboards and analytics.
Long-term direction
The long-term goal is to turn OPN Builder Receipt into a lightweight builder activity record for OPN Chain, useful for ecosystem participation, contributor funding, campaign support, and transparent builder-program records.
On-chain proof

1 contract on OPN Chain.
The chain itself confirmed every deployment is valid, signed by the builder's wallet, and inside the season's window.
