How the OnChainGM referral code works: 15% off, 10% back

OnChainGM (onchaingm.com) is a multi-chain app for sending "GM": a small on-chain greeting that mints a card to your wallet. It supports 66+ networks, charges a flat fee per GM and pays a referral commission on top. Unlike most of the programs on this site, it publishes its numbers, so this guide can show the actual arithmetic instead of hedging. You can compare it with every other deal on our crypto referral codes page.

Quick answer

The ReferralLinks link is https://onchaingm.com?ref=0x102f479312F69157Df8B804905A20FE5025881a5. A friend who arrives through it gets 15% off every GM fee, and you earn 10% of their discounted fee. Your friend is tagged as your referral for 30 days, and the commission lands in your wallet automatically rather than sitting in a dashboard waiting to be claimed.

The standard fee is 0.000029 ETH. With the referral it is 0.00002465 ETH, and your share of that is 0.000002465 ETH per GM. That last number is the one worth remembering, because everything else about the program is a multiple of it.

What is OnChainGM, in plain words?

Sending GM is a ritual in crypto social circles: you post a greeting, sometimes daily, to signal you are around. OnChainGM turns that into a transaction with a souvenir. Each GM mints a card to your wallet, the card is a soulbound token so it cannot be transferred, and the artwork is generated and stored entirely on-chain as SVG rather than on IPFS or a server.

The platform's other product is contract deployment. A factory contract system lets you deploy to several networks at once from one transaction, at 0.000035 ETH per deployment according to its own comparison table, against 0.0002+ ETH for the competitors it lists. If you deploy contracts regularly, that gap is the more valuable part of the app.

The numbers, exactly

Here is the same GM at each stage, using OnChainGM's published figures. The standard fee is 0.000029 ETH. Your friend's 15% discount brings that to 0.00002465 ETH. Your 10% share of the discounted fee is 0.000002465 ETH.

Note what the 10% is calculated on: the discounted fee, not the list price. That is why your cut is 0.000002465 ETH rather than the 0.0000029 ETH a quick mental calculation suggests. It is a small difference per transaction and a real one across thousands.

How the 30-day attribution works

Clicking a referral link tags the visiting wallet as belonging to that referrer for exactly 30 days. Anything they do inside that window counts. If they keep sending GM after the window closes, that activity is no longer attributed to you unless they come back through your link.

The mechanism is per wallet and per action. The published figures describe one GM action at a time, so plan on commission accruing from each GM a referral sends during the window, not from a one-off signup bonus. There is no separate signup payment in the numbers.

Automatic payouts, not a reward balance

A lot of referral programs hold your earnings in an account and ask you to claim them. OnChainGM pays out to your wallet automatically when the fee settles, so there is no claim step and no minimum. That is genuinely convenient, and it has a downside worth naming: you cannot accumulate a balance and withdraw later, so the payout arrives in whatever network the GM was sent on.

Practically, that can leave you with small amounts of ETH-equivalent balance scattered across several chains. If you care about tidiness, check which networks your referrals actually use before you share the link everywhere.

The referral link is a wallet address

Look closely at the URL. The ref parameter is not a username, it is an address: 0x102f...81a5. That is a normal design for on-chain programs, and it creates a specific risk. Anyone who controls a similar-looking address can hand out a link that looks almost identical, and a single changed character sends your friend's attribution, or worse their transaction, somewhere else.

So the rule for this program is stricter than usual: never click a referral link someone DMs you, including a link claiming to be ours. Type onchaingm.com into the address bar, compare the address character by character, and check what your wallet is being asked to sign. Nobody needs your seed phrase to hand you a referral link.

What the fee really adds up to

0.000029 ETH per GM is a tiny amount, which is why the model works at all. OnChainGM's own calculator puts the example at 10 referrals sending 3 GMs a day each: about 0.002218 ETH a month and 0.026622 ETH a year in commission, plus 0.000124 ETH saved on 5 deployments.

Read that as a volume model, not a forecast. Your commission is proportional to how much your referrals actually send, and most people who click a link send a GM once and move on. A realistic early figure is closer to a fraction of a cent per active friend per day.

There is also a gas caveat that the fee line hides. The 0.000029 ETH is the platform's price, not the total cost of a transaction. On a cheap L2 the network fee is a rounding error next to it; on a busy mainnet, gas can easily exceed the platform fee several times over. That is why the 66+ network coverage matters in practice: the cheapest networks are where this model actually stays cheap.

Soulbound cards are permanent

A soulbound token cannot be transferred. You cannot sell the card, gift it, or move it to another wallet. On the plus side, that is what makes it verifiable reputation: the address either has the card or it does not. On the minus side, it also means a mistake sticks. If you mint from the wrong wallet, the card stays there.

The fully on-chain SVG metadata is a real advantage over IPFS-pinned artwork: the image cannot disappear because a gateway went down. Keep in mind that the contract still has to be deployed and indexed for the card to render, and explorers occasionally lag on new artwork contracts.

How to claim the discount

Open the link on this page, or go to onchaingm.com and check the ref parameter is present. Connect a wallet, pick a network and send a GM. The 15% discount is applied to the fee automatically, so the number your wallet shows should already be the discounted one. Compare it against 0.000029 ETH if you want to confirm the discount landed.

If you send a GM without a referral, the full fee applies and there is no way to attach one afterwards. Attribution is a property of the visit, not of the account.

Frequently asked questions

What is the OnChainGM referral code?

The ReferralLinks code is the address 0x102f479312F69157Df8B804905A20FE5025881a5, built into the link at https://onchaingm.com?ref=0x102f479312F69157Df8B804905A20FE5025881a5. A friend who uses the link saves 15% on GM fees.

How much do I earn per GM?

10% of the discounted fee, which is 0.000002465 ETH per GM at the current 0.000029 ETH list price. Your share is calculated on the 0.00002465 ETH your referral pays, not on the list price.

How long does attribution last?

Exactly 30 days from the visit. Activity after that window is not attributed to you unless the person returns through your link.

When are rewards paid?

Automatically and instantly to your wallet when the fee settles, with no claim step and no minimum. Because the payout comes on the network the GM was sent on, it can arrive in small amounts across several chains.

Does the 0.000029 ETH fee include gas?

No. That figure is OnChainGM's platform fee. Network gas is charged separately by whichever chain you use, and on an expensive network gas can exceed the platform fee.
