Uniswap Rolls Out In-App Wallet
-------------------------------

Uniswap shipped support for in-app wallet creation across the Uniswap Web App, Uniswap Wallet, and Uniswap Extension. Users can create a wallet in seconds using a passkey, FaceID, or TouchID, with no seed phrase required during setup, and can export their seed phrase from settings at any time. The infrastructure is powered by Privy, which combines globally distributed key sharding with trusted execution environments for low-latency signing with no single point of failure. Uniswap also added per-token P&L tracking, a multichain portfolio view, and cross-chain swaps powered by Across.

Polygon Launches Open Money Stack

Polygon launched Open Money Stack (OMS) in technical preview, a hosted API that lets businesses move money globally using stablecoins. Cash deposits and bank wires are automatically converted into USDC or USDT on Polygon, with off-ramps back to fiat via ACH, Fedwire, or RTP, and cash onramps live across 48 US states. The platform lets businesses accept stablecoins, generate per-customer deposit addresses, and route to external wallets, with a full API spanning webhooks, RBAC, and SSO.
