Quickstart
Welcome to ONCHAIN® — the access layer for the internet of value.
This Quickstart shows you how to embed instant, on-chain access using a single link: the Universal Access Schema.
You can integrate ONCHAIN® in under 30 seconds.
1. The One Link You Need
Every on-chain asset becomes reachable through a simple format:
https://buy.onchain.money/[chain]/[token]Example (Ethereum token):
https://buy.onchain.money/ethereum/0xabc123...Example (Base token):
https://buy.onchain.money/base/0x1234abcd...Paste it anywhere a user can click — it “just works.”
2. Where You Can Use It
Anywhere links can be placed, the schema works:
Token websites
Wallets
Telegram bots
Discord bots
Explorers (Etherscan, Basescan, etc.)
NFT marketplaces
Portfolio trackers
Launchpads
Community dashboards
CEX → DeFi off-ramps (“Withdraw to token”)
No API keys. No SDK. No backend.
3. Minimal Integration Example
Button example for any website:
Telegram bot example (pseudo-logic):
That’s it.

5. What Happens Behind the Scenes
User opens the link
ONCHAIN® Gateway loads token + chain
User pays (card, Apple Pay, Google Pay, crypto)
Payment is verified
Gateway broadcasts a BuyIntent
OPN executes it natively — no bridges, no custody
Tokens arrive in the user wallet
A single click → fully on-chain settlement.
