Proof you were there.
MaLaew (มาแล้ว — “I’ve arrived!”) turns every meetup, workshop and hackathon into an on-chain memory. Attendees scan a QR code at the venue and mint a soulbound badge in seconds — no app install, no ticket fees, no middleman.
Live on Avalanche Fuji testnet · free for organizers to run
How it works
- 1
Create the event
An organizer creates a badge with a supply cap, a claim window and a secret claim code. It becomes one token id on a single ERC-1155 contract.
- 2
Show the QR at the venue
Print it or put it on the projector. Attendees scan, connect Core or MetaMask, and type the code you announce from the stage.
- 3
They keep it forever
One badge per wallet, minted straight to them. Badges are soulbound by default, so attendance can never be bought or traded away.
Why MaLaew
Soulbound by default
Transfers revert at the contract level, and there is no burn function — once a badge is minted, not even we can take it back. It means someone actually showed up, not that they bought one on a marketplace.
Anti-farming built in
Claim codes are stored only as keccak256 hashes on-chain. Add a time window and a supply cap, and one wallet can only ever claim once.
Nothing for you to deploy
No contract to write, no wallet to fund, no Solidity. Send us the event details and you get a claim page and a QR code back — organizers never touch a block explorer.
Instant at the venue
Avalanche’s sub-second finality means the badge appears while the attendee is still looking at their phone. Fees are a rounding error.
A perfect first transaction
For most attendees this is their first on-chain asset. Every event becomes a friendly wallet-onboarding funnel.
Works anywhere
Any community, any country, any language. Universities, DAOs, hackathons, conferences — if people show up, MaLaew works.
