Referrals

A shared fee, not an extra fee#

The normal Null Cash service fee is 0.50%. A valid referral reduces it to 0.30%: half goes to the link creator and half to Null Cash. On an exchange equivalent to 100 units, that is approximately 0.15 units each. Integer token rounding applies. When a service fee is paid in a converted native asset, the split uses that quoted fee amount.

A qualifying stake waives the service fee completely, so that order earns no referral reward. Provider, network and liquidity costs are separate.

Referral fee payments use one split transaction on Base, Arbitrum and Robinhood, two same-wallet transfers on Ethereum, a single memo transaction on Solana, and a two-output transaction on Bitcoin. The payment screen shows the required steps before you pay; keep both hashes when paying in two parts.

Create a link and invite someone#

Connect an EVM account wallet and verify ownership with a free signature. Create a link and share it. The first valid referral is remembered in the invitee’s browser for 30 days. Verifying their EVM wallet binds the referral to that wallet, so it can be restored after signing in on a different device. Self-referrals do not earn rewards.

Referred users have a $150 staking threshold instead of $250. The same current stake and conservative live token-price checks apply. There is no lock period and no promised APY.

How the referral fee is paid#

The fee invoice shows the exact total and both recipients. On supported EVM networks an atomic batch transfers the project share and creator share in one transaction. ERC20 assets may first require an exact token approval. On Solana, both transfers and the invoice memo go into one transaction. Bitcoin requires a wallet that supports two outputs in the same transaction; both are shown before payment.

The amount exchanged is unchanged. Never send the exchange principal to a service-fee or rewards-wallet address. Small payments must cover chain minimum outputs and network costs.

Pending, available and withdrawn#

Earnings only appear after an actual fee payment is verified. They stay pending until the exchange delivery is recorded. A Basket reward becomes available only after all its legs complete. Incomplete, failed and refunded orders do not unlock earnings. There are no rewards based on unpaid quotes or speculative volume.

The dashboard refreshes every 15 seconds. It separates assets and networks; it does not invent a single USD balance. A referral account is a verified wallet, not proof of a unique person.

Withdraw your rewards#

Rewards wallets on Ethereum, Base, Arbitrum, Robinhood, Solana and Bitcoin are created automatically and managed by Null Cash. This is a custodial rewards account. Connected wallet assets and staking remain separate. Server signing keys are not exposed to the browser.

Choose an available asset, an amount and a destination on that same network. Review the output and network fee, then sign the exact withdrawal authorization with your account wallet. No new approval of tokens in that wallet is needed. The server saves the signed transaction before broadcasting and retries those same bytes if a network request times out.

There is no Null Cash withdrawal fee. Native-coin network costs are deducted from the withdrawal. Token withdrawals may require a native gas top-up to the displayed rewards wallet; other earned rewards are not spent for that gas. Very small rewards may need to accumulate to cover fees or minimum output sizes. A withdrawal does not automatically bridge or convert assets.
