Receipts

Receipts is a public page at hartiilabs.com/receipts, live in Labs 1.54.0. It lists what is deployed so anyone can check it against the chain instead of taking a claim on trust. It is read only: it has no wallet connection and nothing on it signs or sends a transaction.

#What it shows

• This build. The Labs version and commit that are serving the page.
• Releases. Every tagged release since v1.42.0, each with its date and commit. Versions 1.40.0, 1.41.0, 1.43.0 and 1.44.0 shipped without a tag and are not listed.
• Contracts. The core mainnet contracts Labs uses (launch factories, HartiiSwap, LP locker, agent vault factory, QuaiRelay, Boost, Subscriptions), with code size, code hash and a Quaiscan link. Not every address Hartii has deployed.

The data is regenerated by scripts/gen-receipts.mjs before each release, so the page matches the tagged build it ships in. To check a row yourself, call quai_getCode for the address on Cyprus-1, confirm the code is non-empty and compare its size and hash with the page.

#Contracts listed

Addresses are checksummed. Code was confirmed non-empty with one quai_getCode call per address against the Cyprus-1 RPC, verified 2026-11-06.

The sizes above are the deployed runtime code length at the time of the check. The code hashes are on the Receipts page itself; this page does not copy them, because the page is regenerated each release and is the source. Release tags and commits are likewise only on the Receipts page.
