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

Staking SUI currently earns around 1.4 to 1.5% a year at the network level, according to Staking Rewards data as of October 2026. That is a modest figure for a major layer 1, low enough that how you stake matters more than whether you stake, since the differences between routes show up in custody and access to funds rather than in the rate. This guide covers the three real ways to stake SUI. Delegating natively through a wallet, using an exchange product, or holding a liquid staking token, a tr

Asking for the safest stablecoin is really asking four questions at once. What backs the token, who regulates the issuer, has the peg survived stress, and can you actually redeem at size when it matters. Different coins win different questions, which is why every honest answer is a framework rather than a single name, and why the market in late 2026 sorts into three distinct safety models holding everything from $184 billion to a few billion each, per CoinGecko data from 2 October 2026. Here is

EarnPark pays up to 10% APY on USDC as a published base rate as of October 2026, which is the kind of number a yield seeker should hold in mind while reading any exchange review, because exchanges and yield platforms solve different problems and Uphold is firmly the former. Uphold is a multi-asset trading app with a decade of history, a genuinely unusual transparency habit and a loyal XRP-era user base, and its earn side is a regional patchwork that leaves its biggest market out entirely. This

BUIDL is BlackRock's tokenized money market fund, a share class of US Treasury exposure that lives on public blockchains instead of in a brokerage account. It launched in March 2024 as the asset management giant's first tokenized fund, grew into the flagship of an entire asset class, and sits at about $2.25 billion as of 2 October 2026, per rwa.xyz data. The sharper story is what grew around it. Tokenized Treasuries as a category now hold $14.75 billion, and BUIDL is no longer even the largest f

Gemini Earn froze in November 2022 along with the rest of crypto lending, and then its story went somewhere no other frozen platform's did. In May 2024 its users got their crypto back in kind, the actual coins rather than their crash-era dollar value, a distribution of over $2 billion per Reuters that Gemini's own announcement put at $2.18 billion and a 232% recovery against what the assets were worth at the freeze. In 2026 the aftermath finished unwinding, the SEC dismissed its lawsuit over the

Crypto arbitrage is buying an asset where it is cheap and selling it where it is expensive, pocketing the gap between two prices for the same thing. Crypto's fragmented structure, hundreds of venues quoting the same coins around the clock, produces those gaps constantly, which is why arbitrage is simultaneously the most real yield source in this market and the most oversold promise in its marketing. The gaps exist. The question an honest explainer has to answer is who actually captures them, and
