Why "Quiver"?
A quiver is the case archers use to hold their arrows.
We think of each USDT in your wallet like an arrow. Quiver is YOUR case. It keeps your assets organized, ready to deploy, and safely held.
Your money isn't on some exchange or buried in some protocol, it's in your own Quiver.

How it works
1. You have your own Bitfinex account + USDT
We hold zero user funds. Your money stays in your own Bitfinex account.
2. Give Quiver a Bitfinex API key (Funding + Trading scope)
Encrypted with AES-GCM + KEK (same protection as wallet private keys). Quiver can only do four things: place / cancel funding offers, USDT↔USD spot conversion, wallet-to-wallet transfers (exchange ↔ funding), and withdraw to addresses you have pre-whitelisted on Bitfinex (default: your own Quiver wallet). Cannot add new whitelist addresses, cannot buy other coins, cannot transfer to arbitrary third parties. Revoke the key anytime on Bitfinex.
3. Quiver auto-places funding offers for you
Quiver Auto balances deployment and rate for you: most capital sits in FRR market orders to stay deployed; a slice targets fixed-rate market offers; long terms lock only when rates actually spike. Capital is sliced into $500 chunks to spread risk; idle offers convert to FRR automatically. Telegram notifications on spike captures, settlements, and any issues.
4. One-click start, no settings to tune
You decide when auto-lend turns on; Quiver runs a single unified strategy for everyone. We don't time the market for you, never buy other coins, never move to other platforms. One click to disconnect.
Real market rates
Bitfinex Funding lends USDT to margin traders, APY varies with market. Net APY beats traditional bank deposits by 3-10x.
Your money stays in YOUR Bitfinex
Funds always stay inside your own Bitfinex account:
USDT deposits land in your Exchange wallet
→ spot-convert to USD
→ into Funding wallet to be lent
→ at the end, withdraw to an address you pre-whitelisted (default: your own Quiver wallet).
Quiver cannot add new whitelist addresses. Every outbound path is one you set up in advance. Structurally there is no way to send funds to an arbitrary third party.
Free for friend tier
Invite-only friend tier pays no fees. Future commercial version will charge a performance fee, but friend tier stays free forever.
Historical trend tracking
Daily auto-snapshot. Dashboard shows 30-day APY trend, cumulative earnings. Tax season data is ready.
Cross-friend APY ranking
Compare APY with other friends (opt-in), see who has the best strategy and learn.
Compared to other options
Traditional Bank 1-Year Deposit
Stable, but eaten by inflation
CEX Earn (Binance, OKX)
High APY, but Celsius / FTX precedents
Quiver Earn (Bitfinex Funding)
Funds stay in your account, but 2-30 day lock
⚠️ Earn is invite-only beta tooling, NOT a regulated financial product. Quiver is not liable for any Bitfinex / DeFi protocol incidents. Past performance does not predict future results. Crypto is high risk. Invest only what you can afford to lose.

Frequently asked
The four questions newcomers ask most about Bitfinex funding + automation bots.
What is Bitfinex funding (lending)?
Bitfinex funding is a market where you lend your USDT to margin traders on Bitfinex who pay interest. The rate floats with borrower demand: quiet days are 4-8% APR, spike events can hit 30-50%+ APR. It's a CeFi model where your principal sits in your own Bitfinex account.
Why is Bitfinex called the green leaf?
Bitfinex's logo is a green leaf, and the Taiwanese crypto community uses 「綠葉」 (green leaf) as casual slang for the exchange. "Greenleaf lending" is just "Bitfinex funding" in TG / Threads / PTT shorthand.
How does Quiver compare to lending manually on Bitfinex?
Manual lending means watching the screen all day: re-posting offers when they expire, chasing rate spikes, repricing when nothing matches. Quiver is a Bitfinex funding bot. Quiver Auto places offers on a schedule, mixes FRR liquidity with fixed-rate market offers, locks long terms only when rates actually spike, auto-renews on credit maturity, and converts idle fixed-rate offers to FRR before capital sits stale. Real users see ~11-15% effective APR over 30 days.
How is Bitfinex funding different from Crypto.com / Binance Earn?
Crypto.com Earn / Binance Earn take your USDT into a unified pool and pay you a fixed contract rate (typically 4%); the platform pockets the spread. Bitfinex funding is peer-to-peer: your USDT stays in your own Bitfinex account, matched directly with a borrower at the market rate (usually 11-15% APR). You see who borrowed, you can exit anytime, no platform middleman skim.
