Here’s the latest in crypto before the week wraps up. 👇

Coinbase Unveils Everything Exchange With Stocks Trading

Coinbase unveiled a sweeping everything exchange expansion, adding stocks, prediction markets, Solana DEX trading, and stablecoin infrastructure. The rollout targets United States users initially while setting global ambitions across regulated equities, crypto markets, and payments.

Stocks and ETFs now trade commission-free alongside crypto, using dollars or USDC, with hours and planned tokenization. Coinbase also introduced prediction markets via Kalshi and integrated Solana tokens through Jupiter directly inside its app interface.

Custom-branded stablecoins, payments APIs, and x402 standards anchor the strategy, processing over $200 million annualized volume recently. Derivatives access expands with simplified futures and perpetuals, while Base App and AI advisors broaden global distribution reach.

The aggressive push answers intensifying competition from fintechs and DeFi, positioning Coinbase as a unified regulated marketplace platform. By converging assets and rails, Coinbase aims to capture mainstream flows as tokenization and onchain finance accelerate globally.

Kalshi Integrates TRON to Expand Onchain Liquidity

Kalshi integrated the TRON network on December 18 to enable TRX and USDT deposits for global prediction market participants. The integration allows domestic users direct blockchain transfers while international users access liquidity through connected exchanges worldwide. TRON infrastructure adds three-second block times, near-zero fees, and stablecoin scale supporting event trading.

TRON DAO said the partnership bridges traditional finance and blockchain infrastructure as regulated prediction markets expand adoption globally. Kalshi executives cited TRON’s $24 billion daily transfer volume and over $80 billion circulating USDT liquidity. The collaboration reflects broader institutional demand for efficient settlement, regulatory clarity, and scalable onchain financial access.

SoFi Launches Fully Reserved SoFiUSD Stablecoin

SoFi launched SoFiUSD, a fully reserved dollar stablecoin issued by SoFi Bank to support institutional payments infrastructure. The stablecoin operates on a public blockchain, enabling continuous settlement, fractional cent fees, and regulated reserve transparency. SoFiUSD is backed one to one by cash held at Federal Reserve accounts under OCC oversight.

The company plans SoFiUSD usage across banking partners, fintech platforms, remittances, and internal crypto settlement operations. CEO Anthony Noto said stablecoins address slow settlement, fragmented providers, and unverified reserve risks in finance. SoFiUSD will expand availability to members while supporting enterprise integrations through Galileo’s payments infrastructure.

Former Pump Developer Sentenced Over Solana Fraud

Former PumpFun developer Jarett Dunn received six years imprisonment in London after pleading guilty to fraud charges. Dunn siphoned $2 million in Solana from his employer and distributed funds across thousands of random wallets. The incident occurred in 2024 as Pump was scaling early operations and generating under $50 million revenue.

Prosecutors rejected Dunn’s whistleblower defense, citing admissions and social media confessions following the unauthorized transfers. PumpFun later grew into a leading memecoin platform generating nearly $1 billion in cumulative revenue. Dunn remains incarcerated in the United Kingdom after courts denied immediate deportation to Canada.

Data of the day

Crypto losses reached $3.4 billion in 2025 as hackers targeted large platforms and individual wallets worldwide. Three major breaches, including Bybit’s $1.4 billion hack, accounted for 69% of total annual losses. Chainalysis said attackers increasingly pursued fewer but significantly larger exploits using sophisticated access methods.

Personal crypto wallet compromises rose sharply, representing roughly 20% of stolen value despite smaller average theft amounts. DeFi hacks remained comparatively subdued as protocols strengthened security while attackers shifted toward centralized services. North Korean groups stole $2.02 billion using advanced infiltration tactics and long-term operational planning.
