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:

<a href="https://buy.onchain.money/polygon/0xabc123">Buy with ONCHAIN</a>

Telegram bot example (pseudo-logic):

"Buy now → https://buy.onchain.money/" + chain + "/" + contract

That’s it.

5. What Happens Behind the Scenes

1. User opens the link

2. ONCHAIN® Gateway loads token + chain

3. User pays (card, Apple Pay, Google Pay, crypto)

4. Payment is verified

5. Gateway broadcasts a BuyIntent

6. OPN executes it natively — no bridges, no custody

7. Tokens arrive in the user wallet

A single click → fully on-chain settlement.
