Google updated its post-quantum guidance on March 25, setting a 2029 target for full cryptography migration. On March 31, its Quantum and AI team published research suggesting elliptic-curve schemes could be broken with 20x fewer quantum resources than earlier estimates, raising urgency for wallet and signature security.

Analysts warn a Clarity Act proposal could "ring-fence" yield in DeFi, potentially separating staking rewards or protocol revenue from tokens and pressuring designs built around fee sharing. The debate is already prompting teams to revisit incentive structures, while traders watch for volatility tied to tokens marketed around yield narratives.

SWIFT says it is building a working version of a shared-ledger system that lets banks coordinate cross-border payments around the clock using tokenized deposits. The organization expects an MVP to process real transactions later this year while keeping existing banking rules and compliance frameworks in place.

A research paper involving Google warns that sufficiently advanced quantum computers could eventually break elliptic-curve cryptography used by major blockchains, adding pressure to Ethereum's post-quantum transition plans. The authors estimate 1,200–1,450 logical qubits could crack secp256k1 within minutes, with an “on-spend” attack window potentially as short as 9–12 minutes. Ethereum’s roadmap is expected to take years as larger signatures and higher compute requirements complicate upgrades and user migrations.

OpenFX raised $94 million in a Series A round to grow its stablecoin-powered foreign-exchange and remittance payments network. The company said it will deploy the capital to add liquidity, expand into new markets and scale operations across Southeast Asia and Latin America.

Mitsubishi Corporation is set to use JPMorgan Chase’s Blockchain Deposit Account (BDA) system to enable near-instant international fund transfers. The company aims to roll out full-scale global transfers by fiscal 2026 after completing test transactions. The setup is designed for 24/7 U.S. dollar movements across subsidiaries and may support transfers of up to $500 million each.

Metals.io said xU3O8 holders can now pledge the tokenized uranium asset as collateral to borrow stablecoins through an integration with Morpho, with the feature live as of March 30, 2026. The setup runs on the Oku interface and currently enables access to USDC liquidity without selling the underlying physical uranium exposure.

Malicious versions of Axios, a widely used JavaScript package on npm, were published with a hidden dependency that could expose apps—including crypto projects—to a supply-chain attack. Socket Security said the poisoned releases could be pulled automatically by projects using caret version ranges, and noted Axios has roughly 100 million weekly downloads. Developers were advised to check for axios@1.14.1, axios@0.30.4, and plain-crypto-js@4.2.1 and roll back if found.
