Every term, plainly defined.
Plain-English definitions of every technical term used on fendfee. Cross-linked where useful, indexed for AI assistant citation, and updated as our partner roster and payout rails evolve.
UID
User Identifier. A unique numeric or alphanumeric string each cryptocurrency exchange assigns to every account. fendfee uses your UID to match your account to the partner exchange's referral roster and confirm that cashback should accrue on your trades.
Taker fee
The fee an exchange charges when your order is filled immediately against an existing order on the book — you 'take' liquidity. Almost all market orders are taker orders. Taker fees are the primary source of fendfee rebates because they sit higher than maker fees and are paid on every fill.
Maker fee
The fee charged when your order sits on the book waiting to be filled — you 'make' liquidity. Maker fees are typically much lower than taker fees, and on some exchanges become a rebate to the trader. fendfee's rebate is computed against taker fees only.
Rebate
A return of a portion of the fee you paid. In fendfee's context, the daily USDT cashback we credit to your balance based on a percentage of every taker commission you generated on a partnered exchange.
BEP-20
The token standard on the Binance Smart Chain (BSC). USDT on BEP-20 has very low network fees (typically under $0.20) and fast confirmation (seconds). fendfee's payout rail.
TRC-20
The token standard on the TRON blockchain. USDT on TRC-20 is widely supported by exchanges for cheap transfers. fendfee does not currently pay out on TRC-20.
ERC-20
The token standard on the Ethereum mainnet. USDT on ERC-20 is the original USDT issuance, but the network has high gas fees. fendfee does not currently pay out on ERC-20.
KYC
'Know Your Customer'. Identity-verification requirements set by regulators and implemented by exchanges. Most fendfee partners require basic KYC before withdrawals; some require it before trading. fendfee does not collect KYC on its own users for normal cashback flow — only triggered above thresholds defined in our AML policy.
AML
Anti-Money Laundering. The regulatory framework that obliges fendfee and partner exchanges to monitor for and prevent illicit transactions. See fendfee's AML / KYC Policy for the full text.
Affiliate commission
The percentage fendfee pays to a referrer whenever someone they invited earns cashback. Tiered at 15% (1-9 active referrals) or 20% (10+). Paid out of fendfee's share — the referee always receives 100% of their own cashback.
Active referral
Someone you referred to fendfee whose account has at least one approved UID and who has earned cashback in the last 30 days. The active count drives your affiliate tier.
Partner exchange
A cryptocurrency exchange with which fendfee has a referral agreement. Currently Bitget, OKX, WEEX, and BingX are live; Bybit and LBank are signed and arriving soon.
Referral link
The URL fendfee provides for each partner exchange. Signing up to the exchange through this link tags your account so the exchange knows to share its commission with fendfee, which we in turn share back with you as cashback.
Pending balance
Cashback or affiliate commission that has been credited to your account but has not yet been released into your available (withdrawable) balance. Pending balances unlock to available on the next daily review (usually within 24 hours).
Available balance
The portion of your fendfee USDT balance that has cleared review and is ready to be withdrawn to a verified BEP-20 address.
KYC transfer
A feature offered by some exchanges (notably BingX) that lets a user move their existing identity verification from one account to a new account opened via a different referral link. Useful for users who already have a partner-exchange account but didn't open it via fendfee.
Off-chain transfer
An asset movement that happens inside an exchange's internal ledger rather than on a public blockchain. Common for moving funds between two accounts on the same exchange. Off-chain transfers don't have a public block explorer record; fendfee accepts them for payout confirmation but flags them differently in audit logs.
Manual review
fendfee's process of having a human operator examine every withdrawal request before it is broadcast on-chain. Designed to clear within one hour of the user's email-code confirmation. Increases payout safety but doesn't significantly slow them down.
