On March 20, 2024, BlackRock, one of the world's largest asset managers, launched a fund that lived on Ethereum. Not a wrapped token pretending to represent something else. Not a synthetic derivative either. BUIDL, the BlackRock USD Institutional Digital Liquidity Fund, held real US Treasury bills, repo agreements, and cash, with ownership recorded onchain.
Each BUIDL token targets a stable $1 value and pays its yield out as new tokens directly to holders' wallets every day, instead of the usual monthly fund statement. Securitize handles the transfer agent role, keeping a list of approved wallets allowed to hold and move the token, since this isn't a permissionless asset anyone can grab off an exchange. You need to be an eligible institutional investor to get in.
That restriction is the whole point, and also what makes it different from most of what gets called crypto. BUIDL isn't trying to be a speculative asset that goes up because a narrative caught on. It's a plumbing upgrade, taking an asset that already exists, US government debt, and settling ownership of it on a public blockchain instead of through the usual chain of custodians, transfer agents, and overnight batch processing.
By November 2024, BlackRock expanded BUIDL beyond Ethereum to Aptos, Arbitrum, Avalanche, Optimism, and Polygon, letting the same fund settle across multiple chains depending on where institutional demand showed up. The fund grew past $2.5 billion in assets within about two years of launch, a small number next to BlackRock's total assets under management, but a real signal that a firm with zero incentive to chase crypto hype decided tokenized settlement was worth building anyway.
This is the part of crypto that rarely trends on timelines, because there's no chart to stare at and no coin doing a 10x. Real World Assets, or RWA, cover exactly this category: tokens that represent something with cash flow and value outside crypto entirely, treasuries, private credit, real estate, invoices. The pitch is settlement speed and composability. A fund token that lives onchain can theoretically move between institutions, get used as collateral, or settle in minutes instead of days, without anyone picking up a phone to call a custodian.
Skeptics point out that tokenizing a boring treasury fund doesn't require a blockchain at all, and that most of BUIDL's value comes from BlackRock's brand and Securitize's compliance layer, not from anything uniquely decentralized about Ethereum. That's a fair point. The fund still depends on centralized approval lists, a centralized transfer agent, and BlackRock's own legal structure sitting on top of the chain.
But the fact that this exists at all, built by one of the largest asset managers on the planet, on the same network people use to trade memecoins and mint NFTs, says something about where institutions think the plumbing is heading. Ethereum wasn't chosen because it's exciting. It was chosen because enough infrastructure and liquidity already existed there to make the experiment worth running.
Whether RWA tokenization becomes the boring backbone of how trillions in traditional assets settle, or stays a niche product for institutions that wanted a press release, is still an open question.
Would you trust a tokenized treasury fund over a traditional money market account if the yield and access were the same?

Tether launched in 2014 with one simple pitch: every token in circulation would be backed one to one by a dollar sitting in reserve. For years, almost nobody could verify that claim, because Tether never published a full audit, only periodic attestations from accounting firms describing a snapshot of reserves, not a complete audited financial statement.
That gap between promise and proof turned into years of accusations. In 2019, the New York Attorney General opened an investigation into whether Tether and its sister exchange Bitfinex tried to cover up the loss of about $850 million in customer and corporate funds held by a third-party payment processor, using Tether reserves to plug the hole without telling anyone. The inquiry ran nearly two years. In February 2021, Tether and Bitfinex settled, paying $18.5 million and agreeing to publish quarterly reports on Tether's reserve composition for two years, without admitting wrongdoing.
The NYAG's findings were blunt. Investigators said Tether had, at times, held no reserves at all backing the dollar peg, and that from mid-2017 the company lost banking access and misled its own users about liquidity problems during that stretch. That's about as close as a regulator gets to saying a stablecoin issuer wasn't telling the truth about the one thing that makes it a stablecoin.
None of that stopped Tether from growing into the backbone of crypto trading. By early 2026, USDT's circulating supply had crossed $185 billion, holding well over half of the entire stablecoin market, ahead of USDC and every other competitor combined. Over a recent 30-day stretch, USDT changed hands roughly $3.76 trillion worth of times, more volume than Bitcoin itself moved in the same period. In parts of the world dealing with currency instability, from Argentina to Nigeria, USDT has become a practical way people move dollars without touching a bank.
That's the strange part of this story. Tether is simultaneously the asset regulators called out for misleading its own reserve claims, and the asset the entire crypto trading industry depends on to move money between everything else. Every BTC to USDT pair, every arbitrage trade, every exchange balance parked in stablecoin between positions runs through a token whose issuer has never opened its books to a full independent audit.
Tether has published attestations more frequently since the settlement and reports holding a large share of reserves in short-term US Treasuries, a very different balance sheet than the one regulators described in 2019. Whether that's enough transparency depends on who you ask, and mostly on whether you've ever needed to redeem a large amount during a moment of stress.
The peg has held through multiple market crashes that took other stablecoins down with them. Usage keeps climbing every year regardless of the headlines. Maybe that's the market deciding the old accusations don't matter as long as redemptions keep working. Or maybe nobody's tested the reserves under real pressure since 2019.
Do you treat USDT and USDC as the same kind of asset, or does the history change how much of each you're willing to hold?

On August 2, 2016, someone drained 119,756 Bitcoin out of Bitfinex, one of the largest exchanges in the world at the time. At the price that day, the loss came to roughly $72 million. Today that same pile of coins is worth many times more.
Bitfinex didn't quietly stick a handful of unlucky users with the loss. Every account on the platform took the same haircut, about 36% of whatever balance sat there that morning, whether those funds were anywhere near the hacked wallet or not. In exchange, the company issued a new token called BFX, one BFX for every dollar lost, redeemable later at a fixed dollar price or convertible into shares of Bitfinex's parent company, iFinex. Within eight months, every BFX token had been made whole, either bought back at full value or swapped for equity.
That part of the story usually gets forgotten. What people remember is that the stolen coins vanished into the blockchain and nobody expected to see them again.
They sat mostly untouched for over five years, moving in small amounts here and there, enough to keep investigators watching but not enough to break the trail. Then in February 2022, the Department of Justice announced it had traced a huge share of the stolen funds to a New York couple and seized Bitcoin worth close to $3.6 billion at the time, the largest financial seizure in the agency's history at that point. One of the suspects had built a strange public trail of rap videos and posts online for years while allegedly sitting on a fortune stolen from an exchange hack. Both pleaded guilty to money laundering conspiracy in 2023.
The gap between the theft and the seizure says something worth sitting with. Six years is a long time to hide anything on a ledger where every transaction stays permanently visible to anyone who wants to look. Blockchain forensics firms and government investigators spent that entire stretch mapping wallet clusters, watching exchange deposits, and waiting for a mistake. Eventually one came.
Even after the seizure, the story hasn't fully closed. As of early 2025, Bitfinex and individual account holders were fighting in court over whether the recovered coins should go back to the exchange in-kind, meaning the actual Bitcoin itself, or get shared with the customers who took the original 36% haircut, while the government itself had asked the court to approve in-kind restitution to Bitfinex. That distinction is worth billions given how far Bitcoin has moved since the seizure. Bitfinex has argued it's owed the coins themselves as the original victim, and courts have been sorting through exactly who counts as a victim in a hack that technically hit every user's balance at once.
Bitcoin sits at $76,426 today. The 2016 hack is a reminder that exchange security failures don't disappear once the immediate panic fades. They turn into multi-year investigations, legal fights over what a victim is owed, and a permanent case study in how visible a blockchain really is once someone with enough resources decides to follow it.
It also raises a question that never fully goes away for anyone holding funds on a centralized exchange. The coins are recoverable in theory, eventually, if investigators get lucky and have years to spend. That's a very different thing from your funds being safe today.
Would you have kept trading on an exchange right after a hack like that, waiting years for a resolution most users never got to see up close?
