On May 23, 2026, XRP Ledger developer and Xaman wallet founder Wietse Wind warned the XRP community that scammers are impersonating Xaman and pushing fake "desktop wallet" downloads and bogus airdrop claims. He said he is seeing 20+ new X accounts per day and 10+ new domains per day designed to mimic Xaman. Wind urged users to stay vigilant and avoid connecting wallets to unknown sites or installing suspicious apps.

Ethereum's Clear Signing went live on May 12, 2026, with Ledger, Trezor and MetaMask switching signature prompts from hex strings to human-readable transaction details. The change targets signature-phishing losses that reached $6.27 million from 4,741 victims in Q1 2026, while keeping blind signing possible but more avoidable. The standard improves clarity for approvals such as "unlimited" token spend, though it does not remove risks tied to compromised apps or incomplete dApp metadata.

A report cited by Bitcoin journalist Joe Nakamoto says France accounts for about 70% of so-called crypto "wrench attacks," where victims are physically threatened to surrender digital assets. Nakamoto said France has recorded 41 crypto-related kidnappings so far in 2026, and linked the spike to centralized KYC databases and past breaches such as Ledger's 2020 customer-data leak.

Polymarket said a security incident on May 22 led to roughly $520,000–$700,000 in crypto being siphoned from an internal operations wallet, while user funds and core smart contracts were not affected. The activity was flagged after large outflows on Polygon (POL), with reports of about 5,000 POL withdrawn every 30 seconds from addresses tied to its UMA CTF Adapter. The team said it rotated keys and later recovered about $164,000 while trading and market resolutions continued normally.

XRP traded largely flat on Saturday after a week marked by broad crypto selling, slipping nearly 8% over the past seven days. Exchange outflows climbed to about 57.6% while deposits eased to roughly 42.4%, alongside reports of about 4,300 new wallets created in 24 hours and whale accumulation topping 71 million XRP over the past week. At press time, XRP changed hands at $1.33, down 1.19% in the last 24 hours.

Solana Floor warned on May 22, 2026 that scammers are impersonating Jupiter Exchange's Jupuary program by airdropping fake "$CJUP" tokens to Solana wallets and steering users to a wallet-draining phishing site. Jupiter has not announced any active distribution for May 2026, and users are advised to verify eligibility only through the official jup.ag airdrop checker and avoid interacting with unsolicited tokens.

AmericanFortress published a cryptography paper describing a patent-pending, post-quantum signature method for hierarchical deterministic (HD) wallets. The design keeps existing BIP32-Ed25519 public keys and replaces the Ed25519 signing step with a ZK-STARK proof, aiming to avoid chain switches or mandatory fund migration. The paper also reports current performance figures, including sub-10-second signing proofs, 18–19 ms verification, and a fixed 218.4 KB signature size.

Foundation, a Boston-based bitcoin hardware wallet maker, closed a $6.4 million funding round led by Fulgur Ventures to broaden its security stack into identity, multi-factor authentication, and AI agent authorization. The company also made Passport Prime generally available starting at $349 after beginning shipments to pre-order customers in March 2026. Foundation said it plans to launch a KeyOS app store for all users by the end of Q2 2026.

Blockchain.com has confidentially filed for a US initial public offering, signaling another attempt by infrastructure-focused firms to re-enter public markets. The company said on 21 May it submitted a draft Form S-1 to the US SEC for a proposed IPO of its Class A ordinary shares, without disclosing share count or valuation. The filing arrives as IPO discussions intensify across AI, fintech, and crypto infrastructure after a prolonged slowdown.

Glassnode says 6.04 million BTC—30.2% of circulating supply—sits in wallets whose public keys have already been revealed after spending, a setup that concentrates potential quantum-related risk in large custodians. The dataset indicates exchanges hold about 1.66 million exposed BTC, while exposure varies widely by entity, from Binance's 85% to Coinbase's 5% of labeled balances.
