Presale Web3 lets your users pay you directly on‑chain. No custody, no middlemen—just secure multi‑chain checkout, webhook confirmations, and developer‑friendly tooling.
Whether you’re running a multi‑stage token sale or a simple whitelist round, Presale Web3 gives you the plumbing to accept crypto payments directly into your project wallets, with real‑time signals your backend can trust.
Funds settle straight to your wallets. We never hold user funds, private keys, or seed phrases.
Drop‑in JS widget, REST API, and webhook notifications to update allocations instantly.
Support leading L1/L2s and stablecoins. Configure per‑stage pricing, caps, and allowlists.
We emit signed callbacks only after on‑chain confirmations, reducing fraud and double spend.
Event logs and receipt trails for reconciliation with your token allocation engine.
Plug in external KYC providers when your jurisdiction or partners require it.
Define sale stages, accepted chains/assets, min/max purchase, and destination wallets per chain.
Install the checkout widget or call the API. Users pay from their non‑custodial wallets via WalletConnect or native wallets.
On‑chain confirmations trigger signed webhooks so your backend can instantly allocate tokens or queue claiming.
