Flexa said it shut down its SPEDN app on March 31, 2026, ending a seven-year consumer-facing pilot for crypto payments. The company is shifting toward scalable tools for merchants and payment providers, including Flexa Payments and its SDK, while allowing users to withdraw remaining balances to external wallets.

S&P Dow Jones Indices has placed its iBoxx US Treasuries Index on the Canton Network, turning the fixed-income benchmark into a tokenized digital asset for institutional use. The move, announced Tuesday with Kaiko, is meant to let firms pull index pricing and levels onchain via tokens rather than traditional data feeds. S&P said the token is permissioned and not an investable product.

Benchmark began coverage of Securitize on Tuesday ahead of its planned public listing through a merger with Cantor Equity Partners II, assigning a Buy rating and a $16 price target. The analyst framed Securitize as an infrastructure-style beneficiary of tokenization, earning fees across issuance, trading, and ongoing servicing as more real-world assets move onchain.

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.
