Ethereum

Content about Ethereum payments for high-risk merchants (iGaming/betting, FX/CFD, adult, nutraceuticals, VASP/CASP). We cover accepting ETH and ERC-20 stablecoins (USDT/USDC) on ETH mainnet and L2s (Arbitrum, Optimism, Base, Polygon) to reduce fees; invoice/QR flows, address generation & callbacks; instant conversion vs custody, refunds/reversals vs cards; payout/off-ramp options; and risk & compliance: KYB/KYC, AML/KYT, sanctions screening, the Travel Rule (when acting as/with a VASP), and processor/banking policies by market. Also: reconciliation with tx hashes, confirmation policies, hot/cold wallet ops, and chain-analysis controls tailored to high-risk.
