Referral Program
Invite friends to deposit into the USDC vault on Arbitrum and earn ARB token rewards for the entire lifetime of their deposit - automatically, on-chain, claimable at any time.
Overview
Core Liquidity Lab's referral program is built around the USDC vault on Arbitrum. Every time someone you refer deposits USDC and earns ARB bonus rewards, a percentage of those rewards flows to you automatically - no manual tracking, no claiming deadlines.
Your commission rate starts at 10% and scales up to 25% based on how many active referrals you have. The more friends who keep funds in the vault, the higher your tier and your cut.

How It Works
The flow is straightforward: you share a link → a friend deposits USDC → the vault generates ARB bonus rewards → a percentage of those rewards goes to you, automatically, on-chain.
Get your unique link
Open the Referral Dashboard, connect your Arbitrum wallet. Your referral URL generates automatically and is permanently tied to your address - it never expires or resets.
Share it - anywhere
Post on X, drop into Telegram channels, share in Discord. Anyone who opens your link, connects a wallet, and deposits USDC into the vault becomes your active referral.
Earn ARB rewards automatically
Every time the vault distributes ARB bonus rewards to your referees, 10-25% of their rewards is added to your claimable balance on-chain. No action required on your end.
Claim to your wallet
Go to the Referral Dashboard or the Earn page and hit Claim ARB Rewards whenever you're ready. No minimum, no lock - gas is typically ~$0.01.
Commission Tiers
Your commission rate depends on your tier, which is determined by the number of referees who currently have USDC actively deposited in the vault. Tier upgrades - and downgrades - happen automatically on-chain.
| Tier | Role | Active referrals required | Commission rate |
|---|---|---|---|
| Bronze | Starter | 1 -4 | 10% |
| Silver | Builder | 5 -14 | 15% |
| Gold | Influencer | 15 -49 | 20% |
| Diamond | Elite | 50+ | 25% |
Commission is calculated as a percentage of the ARB bonus rewards earned by each active referee - not a fee deducted from their deposit. Both you and your referee benefit simultaneously.
Example calculation
Say you have 8 active referrals (Silver tier - 15% commission rate) and one of your referees earns 200 ARB in a month from their vault deposit. You automatically receive 30 ARB from that single referee. Multiply across 8 active depositors with varying balances and the passive income compounds quickly.

Tracking & Attribution
Everything is handled by the smart contract - transparent, on-chain, and verifiable on Arbitrum at any time.
Wallet-level attribution
A referral is attributed to you when a wallet first connects via your link. That address is permanently recorded on-chain. The attribution persists regardless of device, browser, or future sessions - once tracked, always yours.
One referral per wallet
Each wallet address can only be referred once. If someone opens multiple different referral links, only the first attribution is recorded. This keeps the system fair and prevents double-counting.
Self-referral prevention
Self-referrals are automatically detected and blocked at the smart contract level. Attempting to refer your own wallets results in forfeiture of rewards from those addresses.
Referral Widget on the Earn Page
You don't need to go to the Referral Dashboard to check your stats. The Earn page has a built-in Refer & Earn card that shows your live data right alongside your vault position.
| What the card shows | Details |
|---|---|
| Commission rate | Your current tier rate (10-25%), updates automatically on tier change |
| Referral count | Total friends referred (all time) |
| ARB earned | Total ARB accumulated from referrals |
| Network daily rate | ARB per day flowing from your entire referral network right now |
| Invite friends button | One click → Referral Dashboard with your link ready to copy |
FAQ
How much do I earn per referral?
You earn 10-25% of your referees' ARB bonus rewards, depending on your tier. If a referee earns 100 ARB in bonus rewards, you receive 10-25 ARB on top - for the entire lifetime of their deposit, no expiry.
When can I claim my ARB?
Anytime. Rewards accumulate on-chain in real time. There is no minimum claim amount and no time lock. Gas on Arbitrum is typically $0.01-$0.05 per claim transaction.
How are tiers calculated?
By the number of active referrals - friends currently with USDC in the vault. If a referee fully withdraws, they pause counting toward your tier. When they re-deposit, they count again. Changes happen automatically on-chain.
Is there a referral limit?
No. Refer as many people as you want. The program has no cap on referral count or total earnings. More active referrals = higher tier = higher commission rate (up to 25% at Diamond with 50+ active refs).
What if my referee uses a different wallet?
Attribution tracks the wallet address that first connected via your link. All future deposits from that wallet are attributed to you - regardless of device or browser used later.
Can I refer myself?
No. The smart contract automatically detects and blocks self-referrals. Each address can only be referred once. Violations result in forfeiture of rewards from those addresses.
Do my referees benefit?
Yes. Referees deposit USDC and earn ARB bonus rewards - the same as any other depositor. Your commission is paid on top of their rewards, not deducted from them. Both sides win.
