Bitget and OKX led every exchange in net inflows over the past 30 days, adding +$677M and +$420M. Binance and Bybit went the other way, shedding $1.65B and $416M.

Across all CEXs, $2.09B left the books on net this month. 42 exchanges saw outflows, only 23 saw inflows. Most exchanges lost assets this month. A handful didn't.

Every onchain app needs data — but how you index it matters. The Graph ecosystem gives you two tools: Subgraphs (built-in GraphQL, 15,000+ ready to fork, great for dApps) and Substreams (parallel processing via Firehose, built for high-volume data, ML, analytics).

The simple rule: Subgraphs for queries, Substreams for scale. And with substreams-convert, moving between them is easier than ever.

Before 2026 is out, eight different chains ship their biggest upgrades in years — and the first lands this week. Zcash's Ironwood goes live July 28 (new shielded pool, quantum-recoverable funds).

Zcash update is followed by Ethereum's Glamsterdam, Solana's Alpenglow, Polkadot's JAM, and Cardano's largest upgrade ever. Chainlink is bringing Wall Street's DTCC settlement on-chain, while Polygon and BNB Chain race toward 100k and 10k+ TPS.

Zilliqa suspended all native ZIL transactions after attackers began exploiting a private-key-leaking bug in its Ledger wallet app that had been dormant since 2019.

The flaw is in how the Ledger app generates nonces for EC-Schnorr signatures: the top 64 bits are fixed at zero, so an attacker can rebuild a full private key from just ~5 on-chain signatures. ZIL was drained from an offline cold wallet run by an exchange partner; Upbit and others froze ZIL deposits and withdrawals. Zilliqa has not disclosed the amount and urges users to retire exposed keys and wait for a fix from Zilliqa and Ledger.

Galaxy Digital has launched a Bitcoin Quantum Readiness Initiative to defend Bitcoin’s cryptography against the long-term threat posed by quantum computers.

The program pairs up to $5M in developer grants for post-quantum solutions with a Quantum Advisory Council, plus a research and publishing track run by Galaxy Research.

The concern: a powerful enough quantum computer could one day break the elliptic-curve signatures that secure Bitcoin wallets. Galaxy wants migration paths ready long before that risk turns real.

Block, led by Jack Dorsey, has launched BUZZ, an open-source rival to Slack and GitHub where people and AI agents collaborate inside one shared workspace.

Every human and agent gets a cryptographic identity and its own permissions, running on the decentralized Nostr protocol. Agents join as full members, not command-only bots — Dorsey calls it “model-agnostic, decentralised, self-sovereign and open source.”

From one shared chat, teams move into planning, project management, coding and PRs. A free desktop app is live for macOS, Windows and Linux under Apache 2.0, though BUZZ still calls itself early-stage.

Corporate-finance platform Ramp has launched Stablecoin Accounts, letting its 50,000+ business customers hold USDC and USDT, make cross-border payments and earn rewards — all without leaving Ramp.

Businesses can move USDC and USDT 24/7 with no USD on- or off-ramp fees, and earn up to 3.25% in rewards on balances. Ramp is clear these are activity-based payouts, not interest or investment yield. The core pitch is cross-border payments: a standard wire costs $35-$75 and takes one to three days, whereas stablecoins clear in a matter of seconds — and Ramp already moves ~$100B a year.

Confidentiality protocol Zama has partnered with blockchain-intelligence firm Elliptic to bring compliance screening to confidential onchain finance — without giving up privacy.

Zama builds a confidentiality layer for public blockchains using fully homomorphic encryption (FHE). Elliptic’s screening lets institutions meet AML and regulatory standards on transactions that stay encrypted — “compliant by design.”

The pitch: institutions won’t adopt confidential finance unless it satisfies regulated-market compliance, and now it can. Zama recently raised $57M in a Series B to expand its FHE stack.

Pavel Durov says Telegram will build a native, non-custodial Gram wallet into every version of the app this summer, bringing instant, zero-fee crypto to its 1B+ users.

Durov calls it the largest non-custodial wallet deployment in history. It supports Gram — Telegram’s native token, rebranded from Toncoin in June — and keeps users in full control of their keys, secured by two-factor authentication on their Telegram account.

Built on the MyTonWallet engine, it follows a 2025 pilot that put a non-custodial TON wallet in front of 87M US users. Now the rollout goes global across the whole app.

Shareholders of UK Bitcoin-treasury firm Satsuma Technology have voted, with over 90% support, to sell off its entire Bitcoin stack, delist from London, and hand the capital back to its investors.

Satsuma will sell 668 BTC (~$43.5M) and return the capital to investors, overruling four of its six board members. It is a fast unwind: under a year ago it raised $218M in a ParaFi-led round and hired Mark Moss as chief bitcoin strategist.

The trigger: SATS shares fell over 99% from their 2025 peak, pulling the market cap well below the value of the Bitcoin on its books. UK court hearings run into September, with delisting due mid-September.
