Japan's Top Banks Plan Joint Stablecoin as Coinbase Logs $19T, Botanix Shuts Down

Crypto News

Botanix, a Bitcoin Layer-2 protocol built to bring decentralized finance to Bitcoin, confirmed it will shut down, with all services ending on July 9, 2026. After more than four years validating demand for Bitcoin-native applications, the team concluded its business model was no longer sustainable under prevailing market conditions. The project said users prioritized convenience over decentralization, slowing adoption, while wrapped Bitcoin and general-purpose Layer-2 networks already absorbed most existing demand. Botanix urged remaining users to withdraw all assets before the closure date, warning that access to funds could be disrupted once the platform goes offline permanently.

Japan's three largest banking groups — MUFG, SMBC and Mizuho — announced plans to issue a joint stablecoin before the fiscal year closes in March 2027. The lenders will form a dedicated council to design the operational framework, acting as co-founders while a trust bank serves as custodian. Regulators have signaled support, with the Financial Services Agency backing the initiative and the ruling party urging promotion of yen-pegged tokens. Dollar-denominated coins still dominate: USDT and USDC together hold 84% of the roughly $311 billion market, while yen-based tokens remain under $50 million, led by JPYC at about $18 million.

Hyperliquid's policy arm and venture firm Paradigm urged the US Treasury to narrow proposed anti-money-laundering and sanctions rules for stablecoin issuers. In a letter responding to April's regulatory proposal under the GENIUS Act, the two argued that secondary-market obligations could damage permissionless infrastructure and DeFi. They backed FinCEN's focus on primary-market issuers with direct customer access, noting that in secondary markets issuers typically see only wallet addresses and transactions. Imposing broad compliance duties on smart-contract interactions, they warned, could push regulated dollar stablecoins out of decentralized venues entirely, with implementation targeted no later than January 2027.

Coinbase spotlighted the scale of its stablecoin operation, consolidating payments, compliance, custody and fiat rails into a single regulated product called Coinbase Payments. The company said its Base network processed more than $19 trillion in stablecoin volume during 2026, while it holds roughly $20 billion in USDC and moves about $1 trillion in stablecoins annually. Its autonomous payment protocol, x402, completed over 160 million machine-to-machine transactions in the past year. Coinbase, operating under more than 80 licenses worldwide, said the framework lets fintechs, banks and payment firms access KYC, KYB, treasury and card infrastructure without rebuilding compliance in every jurisdiction.

Frax Finance founder Sam Kazemian outlined an aggressive path for FRAXUSD, aiming to make it one of the first GENIUS-compliant stablecoins once US licensing fully activates in the first quarter of 2027. He claimed Frax has signed payment agreements with major Web2 and publicly traded companies seeking economically risk-free, compliant digital dollars for treasury and payroll use. Revenue from those deals would partly fund FRAX token burns and partly fund research. Kazemian predicted the stablecoin market, long range-bound between $100 billion and $200 billion, could surge to $600-700 billion within six to eight months if a major bank moves significant deposits on-chain.

Anthropic released Fable 5, the first public version of its Mythos model, intensifying debate over decentralized finance security. The firm previously disclosed the model identified over 10,000 high or critical vulnerabilities in widely used software, and it routes sensitive cybersecurity requests to an older model as a guardrail. Critics including Moonrock Capital's Simon Dedic warned that finding exploitable smart-contract flaws could become nearly free, urging users to revoke wallet permissions and move assets to fresh hardware wallets. The concern lands amid rising losses: crypto stolen through attacks reached $629.7 million in April, the highest since February 2025. Curve's Michael Egorov countered that operational security poses the larger threat.

Across these developments, a single arc emerges: stablecoin infrastructure is consolidating into regulated, institutional hands just as the experimental, fully decentralized fringe — exemplified by Botanix — retreats. COINOTAG's aggregate market data underscores the caution, with the Fear & Greed Index pinned at 9 (Extreme Fear) and total crypto market capitalization near $1.76 trillion. Bitcoin dominance sits at 70.2%, signaling capital rotating toward the largest blockchain as risk appetite contracts. The GENIUS Act framework and Japan's bank-led model suggest the next stablecoin cycle will be defined by compliance, not permissionless experimentation — a structural shift our data shows the market is still pricing in.
