01 / PaymentsLive

HPAY

Get paid in one tap with Receive, send QUAI to a person by name, or make a link that lets someone pay you. The recipient is shown to you before anything is sent. Beta tools price a link in dollars, take payments in a shop, print receipts, split a bill, list the QUAI payments a wallet sent and received in an inbox, read a statement and add a Pay with HPAY button to a website.

Open HPAY ↗︎
Who it is for & what it costs +

Anyone who sends or receives QUAI: friends splitting a cost, freelancers invoicing, communities collecting contributions.

Service fee
None
Network gas
Paid to the network, estimated in your wallet
Dollar prices (beta)
Locked for 15 minutes, from two price sources that agree within 2 percent

Receive only reads your connected account. It never signs or sends, and shows your address only on Quai Mainnet (Cyprus-1).

HartiiLabs launchpad

A launchpad on Quai. Anyone can create a token; it trades on a bonding curve, then keeps trading in its own pool, inside the same contract, once the curve has raised 25,000 QUAI net.

Open HartiiLabs ↗︎
Who it is for & what it costs +

Creators who want to launch a token with a public price curve, and traders who want to trade it from the first block.

Launch fee
5 QUAI (read from the factory contract)
Curve trading fee
1% per side while on the curve

Nothing here is financial advice or a promise about price. Tokens and NFTs can lose value.

The story / made in the open

Useful things.
A point of view.

Hartii is an independent collection of software for life on Quai. A payment should reach a person. A score should be verifiable. A work of art should carry its provenance.

The products do different jobs. What connects them is a preference for clear actions, visible costs and work you can inspect.
