Funding rate arbitrage is the trade behind most of the "delta-neutral" yield in crypto. You buy an asset, short the same amount of its perpetual future, and collect the payments that leveraged buyers make to sellers to keep that contract tied to the spot price. Price moves largely cancel out, and what is left is a stream of funding payments. It is real income with a clear economic source, and it is the engine inside Ethena's USDe, inside institutional basis desks and inside several managed yield

OpenEden's TBILL fund pays roughly what short-dated US Treasury bills pay, minus a 0.35% annual fee, and it holds close to $295 million doing it. S&P rates the fund AA+f, BNY manages and holds the bills, and the structure is about as conservative as on-chain yield gets. The catch is at the front door. TBILL is open only to professional or accredited investors, and the first deposit has to be at least 100,000 USDC. Most OpenEden pages describe the safety in detail and skip the part about who is

USDY trades at about $1.15, is not a stablecoin, and was listed at 3.75% APY when we checked on 18 October 2026, a rate that can change. Each of those facts confuses people who meet it for the first time on an exchange listing or a DeFi dashboard, because it sits in the same column as USDT and USDC while behaving like neither. A USDY token is a claim on a portfolio of short-dated US government debt, packaged so it can move between wallets like any other token, and sold only to non-US investors w

Hyperliquid's vault list has an APR column, and HLP, the exchange's own vault, sits at the top of it. The trouble is that the column looks like a savings rate and behaves nothing like one. When we checked in October 2026, the HLP vault showed an APR of roughly 3.5% on about $178 million of deposits, and a large share of the vault's lifetime profit arrived in a handful of violent days rather than as a steady drip. That is not a reason to avoid it. It is a reason to understand what you are buying

Binance Earn is the yield wing of the world's largest crypto exchange, and the first thing an honest review has to tell you is that the rate you saw advertised is probably not the rate you will earn. Per Binance's own terms for Simple Earn, its core savings product, the flexible rate is a Real-Time APR that can change every minute, and the bigger headline numbers come from Bonus Tiered APR, a promotional rate offered "from time to time on selected products" through a tiered structure that can sh

crvUSD is the decentralized stablecoin issued by Curve Finance, created when users borrow against crypto they deposit. Its peg is managed by dedicated PegKeeper contracts, and its loans are protected by a liquidation design that works differently from the single-threshold liquidations most lending systems use. About 241 million crvUSD circulate as of 10 October 2026, trading within a tenth of a cent of $1 per DefiLlama. That makes it a mid-sized stablecoin, far from USDT scale, but its design is

Proof of reserves, a report showing the assets a platform holds measured against what it owes its users, has become the crypto industry's standard trust signal. It got there fast. When FTX collapsed in November 2022, CoinDesk reported nine major exchanges announcing within a single day that they would publish reserve certificates in the month ahead. Nearly four years on, the technique is everywhere, and so is the confusion about what it actually proves. This piece explains how proof of reserves

Impermanent loss is what happens to a liquidity provider when the prices of the pooled assets drift apart. You end up with less value than if you had simply held the two assets in a wallet, even though the pool kept earning fees the whole time. It is the defining risk of liquidity providing, the reason attractive pool APYs keep disappointing the people who chase them, and probably the worst-named concept in DeFi, because the loss is only impermanent if prices come back, and prices owe you nothin

Restaking takes capital that is already staked securing Ethereum and pledges it again to secure additional services, earning a second stream of rewards on the same coins. EigenLayer pioneered the category on Ethereum, holds about $7.1 billion as of 2 October 2026, per DefiLlama, and spawned an ecosystem of liquid restaking tokens, rivals and a Bitcoin cousin. The pitch is capital efficiency, one asset earning twice. The physics is that one asset is also liable twice, and after two years of airdr
