DeFi's Near-Death Moment | Mike Silagadze on Ether.fi, Security, and What Comes Next

How close did DeFi come to a systemic collapse? Camila Russo sits down with Mike Silagadze, co-founder and CEO of Ether.fi, for the full post-mortem on the Kelp exploit and the DeFi United rescue — why the default path could have been far worse if nobody had stepped in, and why he draws a hard line between industry coordination and a bailout.

Silagadze's sharpest claim: the biggest protocol failures come from basic operational security gaps, the kind serious teams can prevent. The argument maps directly onto today's exploit reports — Raydium's $1.34M drain and the Humanity Protocol post-mortem that traced a $36M loss to a single malware-infected laptop.

Mastercard Opens Card Rails to AI Agents With 30-Plus Crypto Partners

Mastercard launched Agent Pay for Machines (AP4M) on Wednesday, extending its card network to autonomous AI agents with 31 launch partners including Coinbase, RippleX, Solana Foundation, Polygon, Aave Labs, and Stellar. The platform credentials registered agents, attaches spending limits and authorization rules, and settles in traditional currencies or stablecoins. Stani Kulechov, founder of launch partner Aave, described the protocol as the "credit layer for agentic payments".

Why this matters: Mastercard is the identity and governance layer most institutions will trust for machine-to-machine commerce, and it chose stablecoin settlement from day one. Credentialed agents give banks a compliance surface they can underwrite; the partner list puts Solana, Polygon, and Stellar in line for that settlement flow.

Ripple Deploys XRPL AI Starter Kit as Mastercard Names It Agentic-Commerce Partner

Ripple released the XRPL AI Starter Kit, a phased developer toolkit for AI-agent payments on the XRP Ledger in XRP and RLUSD. Phase 1 ships an XRPL docs MCP server, two Claude skills covering wallet creation and payments, and an integration with the x402 standard that lets agents pay for API calls and model inference. The launch landed the same morning Mastercard named RippleX an AP4M partner, slotting XRPL into the new network's blockchain settlement layer.

Why this matters: RLUSD gets a defined job: stable-denomination settlement for agent workflows where issuer credibility matters. Ripple joins Fireblocks, MetaMask, and Solana in shipping agent tooling within a month.

DOJ Opens Debanking Probe Into JPMorgan, Bank of America and Wells Fargo

Federal prosecutors subpoenaed JPMorgan Chase, Bank of America, and Wells Fargo over whether the banks unlawfully closed customer accounts for political reasons, the Wall Street Journal reported. The U.S. Attorney's Office in Washington, D.C. is testing the closures against FIRREA, the 1989 bank-fraud statute. FDIC documents obtained by Coinbase showed staff advising banks to limit crypto relationships starting in 2022, and a House report counted at least 30 entities cut off through informal supervisory pressure.

Why this matters: A DOJ finding would recast the 2022–2023 closures as unlawful conduct, strengthening crypto firms' standing in disputes over banking access. Regulators already stripped reputation-risk language from supervisory guidance this month. Watch Custodia's Supreme Court petition, with filings due July 11.

Japan Megabanks MUFG, Mizuho, and SMBC Establish Joint Stablecoin Council

Mitsubishi UFJ, Mizuho, and SMBC established a joint stablecoin council targeting live yen-stablecoin transactions by March 31, 2027, the end of Japan's fiscal year. The three banks will act as joint settlors on a trust contract, with trust banks as trustees issuing the coin as an electronic payment instrument under the 2023 Payment Services Act. The council's charter leaves an open path for other financial institutions to join the architecture later.

Why this matters: USD tokens hold nearly all of the $300 billion stablecoin supply. A yen instrument from banks of this scale is the first credible sovereign-currency alternative on Asia's trade corridors — and a template other banking consortia can copy.

Binance Converts Stock Holdings Into On-Chain Tokens With bStocks Launch

Binance activated bStocks, converting live brokerage stock positions into BNB Chain tokens tradable around the clock. The first five: Nvidia, Tesla, Circle, Micron, and Sandisk. Users holding the underlying shares through Binance's ADGM-regulated brokerage convert 1:1 with no lock-ups or conversion fees, withdraw to self-custody wallets, and deploy the tokens in DeFi. Issuer BTech Holdings structures the tokens as rights tied to the securities without direct share ownership.

Why this matters: Binance hands users the conversion function themselves; competitors pre-issue fixed token sets. Distribution decides this race, and Binance starts with the largest captive crypto user base. NYSE's proposal to trade tokenized securities under existing tickers shows the incumbents responding in kind.
