Due-diligence snapshot of an ERC-20 token on OP Mainnet: name, symbol, decimals, supply, owner and whether ownership is renounced, upgradeable-proxy detection, owner-only functions found in the bytecode (mint, pause, blacklist, fee changes), and USD price, liquidity and FDV from the deepest WETH or USDC pool on Uniswap v3 or Velodrome. Facts only, no buy or sell opinion.

Human-readable summary of a OP Mainnet transaction: status, block and time, sender and recipient, ETH value, gas used and fee, method selector, and decoded ERC-20 transfers with token symbols and amounts.

New trading pools created on OP Mainnet in the last N minutes on Uniswap v4, Uniswap v3 or Velodrome: both tokens with symbol, name and decimals, fee tier, v4 hooks, whether it pairs with ETH, WETH or USDC, and quote liquidity where readable. Unvetted: many new pools are spam.

Whale and large-trade tracker for an ERC-20 on OP Mainnet: every buy and sell in the last N minutes on the token's deepest WETH/USDC pools (Uniswap v3 or Velodrome), with USD size, side, wallet and transaction for the largest trades, buy/sell volume and net flow, and the wallets that bought or sold the most.

Sorts groups by size, then assigns each to the available room that has all required features and minimizes unused capacity, hourly cost and room identifier in that order. This fast heuristic is not guaranteed globally optimal and does not handle time overlap, accessibility beyond supplied features, movement, privacy or building-code constraints.

OFAC Sanctions Check — crypto address. OFAC sanctions wallet screening: check a crypto address against the U.S. Treasury SDN list before you send or accept funds — exact match across 18 currencies (ETH, XBT, SOL, USDT, USDC, TRX, BSC, ARB, XMR, LTC and more), EVM case-insensitive, with the sanctioned entity, program and list date.

OFAC Sanctions Screening — names and aliases. OFAC sanctions screening by name for people, companies, vessels and aircraft: fuzzy matching against ~19,000 SDN entries and their aliases (handles word order, accents and spelling variants), with match scores, programs, remarks and OFAC links. A screening aid for compliance and AML checks.

OFAC SDN screen — fuzzy-screen a person or organization name against the public OFAC SDN list (including aliases). Returns scored potential matches. Not clearance.

Uses the nearest current DWD MOSMIX_L station forecast, or a station explicitly supplied by the caller. Global irradiance drives a transparent PV estimate and forecast wind speed drives a stated generic turbine curve; neither replaces a site-specific yield model. A constant hourly load and optional battery are simulated over 12 to 120 hours. The result is an installation-risk signal, not an official weather warning, emergency alert or guarantee of supply.
