What Is Web3?.
Web3 is the name for a version of the internet where the application's state lives on a public blockchain rather than on a company's servers, so accounts, balances and ownership records are controlled by keys the user holds instead of by a platform that can revoke them. In practice that means you sign in with a wallet rather than an email address, and the rules of the app are enforced by code that anyone can read.
The pitch is that this removes the platform as a permanent middleman. If your account, your followers, or your in-game items live on a shared ledger, no single company can delete them, change the terms, or lock you out. The cost is that everything becomes your responsibility: lose the keys and there is no password reset, sign a bad transaction and there is no chargeback.
Most of the technology in this series exists to make that tradeoff less punishing, or to make the underlying chains fast and cheap enough to be usable. Rollups cut fees. Account abstraction makes wallets behave more like normal accounts, with recovery and spending limits. Oracles let contracts read real-world data. Stablecoins give the system a unit of account that does not swing 20% in a week, and are the one component with clear, large-scale adoption today.
The series below explains each piece on its own terms, including where the honest limitations are.

Ethereum L2s Hit a 2-Year Low. ZK Rollups Are Empty.
Ethereum layer-2 value has fallen back to levels last seen in 2023. Our own DefiLlama pull shows why the headline understates it: Base alone holds 69 percent of L2 DeFi TVL, while ZKsync Era sits at $14 million and Polygon zkEVM rounds to zero.

Aztec V5 Moves Ethereum Privacy Proving to Your Laptop
Aztec's Alpha V5 upgrade passed token-holder governance and executed onchain this week, moving zero-knowledge proof generation off remote servers and onto users' own devices. A private token transfer now proves in about 2.5 seconds natively, down from 5.2, and fully private transaction costs fell roughly 50%.
Web3
Across Got Hit on Solana and Users Lost Nothing
Across Protocol was attacked on its Solana deployment on July 17, 2026, its first incident after $34 billion in bridged volume. No user funds were lost because the protocol's intent-based design puts relayer capital at risk instead of a pooled contract.
Web3
A Zeroed Signature Drained $9M From Bonzo Lend
An attacker deposited 250 SAUCE tokens worth a few dollars, pushed a price update with an empty signature that Supra's Hedera oracle verifier accepted, and borrowed $9.05 million against it. The whole thing took about eight seconds. Hedera's network TVL fell nearly 40% in a day.

Aavenomics 3.0 Routes 100% of Revenue to the Aave DAO
Aave unveiled Aavenomics 3.0, hardcoding its token buyback at the protocol level and routing 100% of revenue from the protocol, the GHO stablecoin, and ecosystem products to the DAO treasury, while expanding lending and GHO onto the high-speed Monad chain.

Summer.fi Loses $6M in a Morpho Flash-Loan Exploit
An attacker drained about $6M from Summer.fi's Lazy Summer Protocol vaults by taking a flash loan through Morpho to inflate the vaults' accounting, then redeeming the overstated balance for profit. The SUMR token fell more than 18% as DeFi's worst exploit year continues.
Web3
Aave in Talks to Sell Kraken 15% Stake at $385M

Summer.fi halts vaults after a $6M flash-loan hack
DeFi protocol Summer.fi paused its Lazy Summer vaults after a flash-loan attack drained about $6M by manipulating the USDC vault's accounting, briefly spiking a displayed APY past 2 million percent. Its SUMR token fell over 18%, and the multichain setup made the blast radius bigger.

Crypto wallets and self-custody, explained
A crypto wallet is your identity and account in Web3: a pair of cryptographic keys that let you hold assets and sign transactions yourself, without a bank or platform holding them for you. Self-custody means you control the keys, which means total ownership and total responsibility, no password reset if you lose them.
Web3
Smart contracts, explained: code that runs itself
A smart contract is a program stored on a blockchain that runs exactly as written when its conditions are met, with no company able to alter or stop it. It replaces a trusted middleman with code, powering everything in Web3 from token swaps to lending to NFTs, and it is only as safe as the code it is written in.
Web3
DAOs, explained: can a company run on code?
A DAO, decentralized autonomous organization, is a group that coordinates and controls shared funds through smart contracts and token-holder voting instead of a traditional management hierarchy. It promises transparent, member-owned governance, and in practice wrestles with voter apathy, whale dominance and the limits of running an organization on-chain.
