Casper Prepares Launch of Updated csprUSD

Abstract

The Casper blockchain platform, in collaboration with investment firm Sarson Funds, is preparing to launch an upgraded version of its csprUSD stablecoin. Upon release, it will become the primary dollar-pegged stablecoin within the Casper ecosystem. A key use case will be facilitating automated payments between AI agents via the x402 protocol. This development follows the recent establishment of the x402 Foundation under the Linux Foundation, which includes members like Visa, Mastercard, Google, Coinbase, Circle, Stripe, AWS, and Cloudflare. The x402 protocol enables AI agents to autonomously pay for goods and services online using standard HTTP requests, bypassing traditional payment systems. The new csprUSD will be compatible with Casper 2.0 and support the CEP-3009 standard. It will allow users and AI agents to confirm payments off-chain, with final settlement occurring on the blockchain. The ecosystem will also integrate Casper's ProofLayer technology, which provides cryptographic verification for off-chain data. This will be used to verify the dollar reserves backing csprUSD and to monitor token issuance and redemption. Prior to the mainnet launch, the stablecoin's smart contract will undergo an independent security audit. Casper has also recently reduced its minimum transaction fee from 2.5 CSPR to 0.1 CSPR following the approval of proposal CEP-97.

The x402 protocol allows AI agents to independently pay for goods and services online by sending standard HTTP requests without using traditional payment systems.

The new version of csprUSD will be compatible with Casper 2.0 and will support the CEP-3009 standard. Users and AI agents will be able to authorize payments off-chain, with their execution then occurring on-chain. The ecosystem will also integrate Casper's ProofLayer technology, which generates cryptographic proofs for data residing off-chain. This will enable verification of csprUSD's backing by dollar reserves and monitoring of token issuance and redemption.

Before the mainnet launch, the stablecoin's smart contract will undergo an additional independent security audit. Previously, Casper also reduced the minimum transaction fee from 2.5 to 0.1 CSPR following the approval of proposal CEP-97.

Expect news tomorrow: this time the Bank of Japan will announce its interest rate decision! What impact will this have on Bitcoin?

A day before the Bank of Japan's (BOJ) interest rate decision announcement, the Japanese yen surged nearly 3% against the US dollar. The sharp move in the currency market fueled speculation that the Japanese government may have intervened again to support the yen. The USD/JPY pair fell over 400 pips to 158.5, its steepest daily drop since Japan's currency intervention earlier this year. Market participants suspect the rapid, strong yen appreciation could be due to direct foreign currency sales by Japanese authorities, though the Ministry of Finance has made no official statement. The yen had previously fallen to its weakest level against the dollar in nearly 40 years. In late April and May, the government intervened with roughly 9.6 trillion yen to prevent the USD/JPY from rising sustainably above 160, but the yen faced renewed selling pressure afterward. Investors are now focused on the BOJ's rate decision and its signals on future monetary policy. Potential hawkish signals from the BOJ are seen as a factor that could support further yen strength. A sharp yen appreciation could create short-term selling pressure on Bitcoin by increasing the risk of unwinding carry trades, where investors borrow low-yielding yen to invest in Bitcoin and other risky assets. This pressure could intensify if the BOJ takes a hawkish stance or raises interest rates.

Bitcoin stable as Fed fave PCE inflation sees first monthly drop in six years

Bitcoin remained stable around $64,500 despite the release of key U.S. inflation data. The June Personal Consumption Expenditures (PCE) index, the Federal Reserve's preferred inflation gauge, showed a year-on-year increase of 3.7%, matching expectations and ending a recent uptrend with its first monthly decline since 2020. However, analysts cautioned that inflation remains nearly double the Fed's 2% target. Concurrently, U.S. stock markets rebounded, easing pressure on crypto assets. Following the Fed's decision to leave interest rates unchanged, Bitwise CIO Matt Hougan predicted Bitcoin will become less sensitive to future Fed rate changes, anticipating more modest policy adjustments ahead.

Bernstein Reveals Details of Core Scientific's $14 Billion Deal with AMD

Analysts from Bernstein revealed details of a deal between Core Scientific and AMD with a potential total value of over $14 billion. According to the report, initial contracts for 530 MW of capacity could generate this revenue over 15 years, with AMD acting as a credit guarantor for part of the bitcoin miner's infrastructure. The partnership, announced on July 28, has the potential to allocate up to 2.5 GW of data center capacity for AI. Bernstein broke down the 530 MW into 377 MW of direct triple-net lease for AMD and 152 MW for an unnamed cloud provider backed by AMD's credit. This structure is seen as lowering financing costs and counterparty risk. AMD also received warrants to buy 30 million Core Scientific shares at $23.47 each, which vest upon reaching the 2.5 GW target. Average annual revenue from the deal is estimated at around $0.9 billion, or about $1.8 million per megawatt, which is 5-25% below recent AI hosting deals by other miners. However, the 377 MW triple-net lease for AMD carries a margin close to 100%. Core Scientific expects capital expenditures for the deal to be $11-12 million per MW, totaling about $6 billion. Bernstein views this partnership as a new phase in the transformation of former bitcoin miners into AI infrastructure operators, with AI chipmakers like AMD now acting as direct anchor tenants. Recent similar deals include Hut 8 allocating 704 MW to a tenant believed to be Nvidia, and AMD reserving 200 MW with Riot Platforms. Core Scientific also paid Block $41.9 million to terminate a mining chip supply contract as part of its accelerated diversification into AI.

Hyperscale Data sells 100 BTC to fund Michigan AI data center

Bitcoin mining company Hyperscale Data has sold approximately 100 Bitcoin and obtained a Bitcoin-backed loan to fund the construction of its new AI data center in Michigan. The proceeds are for infrastructure and equipment, with the credit facility carrying an interest rate of 4.5% to 5%. The project supports a 10-year deal with an unnamed AI provider for 20 megawatts of capacity, potentially generating over $1.2 billion in revenue. Options to expand and extend the contract could increase its total value to more than $3 billion. Hyperscale Data, formerly Ault Alliance, continues its Bitcoin mining operations and remains a significant corporate holder with about 1,006 BTC.

Gumi and SBI Launch a 3 Billion Yen Cryptocurrency Fund, and Japan Opens Doors for Spot ETFs

Japanese gaming and blockchain firm gumi Inc. has partnered with financial group SBI to launch the SBI Crypto Fund I, starting August 1, 2026. The fund aims to raise 3 billion yen (approx. $18.3 million) and will invest in Bitcoin and major altcoins, using strategies like staking and hedging. SBI Financial Services holds a 51% stake, with gumi's gC Labs owning 49%. This move aligns with Japan's regulatory shift, where new laws will reclassify digital currencies as financial instruments (effective 2027), paving the way for future spot Bitcoin ETFs and stricter penalties for unregistered crypto activities. Tax rates on crypto gains are also set to drop from 55% to 20% in 2028. In related developments, SBI VC Trade, a crypto exchange under SBI Holdings, reported its registered accounts recently surpassed 2 million, doubling from 2025. Growth is driven by corporate adoption of Bitcoin and XRP to hedge against yen weakness, and the introduction of yen and dollar-pegged stablecoins. Despite a smaller market than the US or South Korea, Japan's crypto sector is gaining momentum.
