Overview: The Ethereum payment method is a way to accept on-chain payments in ETH or supported ERC-20 tokens. Customers pay from their crypto wallets to a merchant wallet or a payment gateway that monitors the blockchain and confirms the transaction. How it Works: 1) Customer selects Ethereum at checkout and sees a payment address or QR code with the exact amount. 2) The customer sends funds from a wallet (e.g., MetaMask, Coinbase Wallet, Trust Wallet). 3) The gateway detects the transaction and waits for network confirmations. 4) The order is marked paid; the merchant can settle in crypto or convert to fiat via the gateway. Benefits: - Global reach without traditional card rails - Fast settlement with transparent on-chain records - Programmable commerce via smart contracts (e.g., escrow, milestones) - Enhanced security through decentralized verification Fees and Confirmations: Payments include a network “gas” fee, which varies with congestion. Merchants and gateways typically require a small number of confirmations to reduce risk of reorgs. Layer 2 networks (such as Optimism, Arbitrum, and Base) offer lower fees and faster finality while remaining anchored to Ethereum security. Supported Assets and Wallets: Most gateways accept ETH and popular ERC-20 tokens (e.g., USDC). Customers commonly use MetaMask, Coinbase Wallet, or mobile wallets. Always verify the network (Mainnet or a specific L2) and token contract to avoid mis-sends. Price Volatility and Settlement: If accepting volatile assets like ETH, merchants can auto-convert to stablecoins or fiat to reduce exposure. Stablecoins can minimize price swings while preserving crypto-native checkout. Refunds and Disputes: On-chain payments are push transactions; refunds are performed by sending funds back to the customer’s address. Gateways may provide refund workflows and audit trails, but there is no card-style chargeback. Compliance and Security: Merchants should follow local regulations, tax rules, and AML/KYC obligations when converting to fiat. Use unique payment addresses per order, enable risk checks, and store only necessary data. Never ask customers for seed phrases. Integration Tips: - Display the exact amount, network, and token with a countdown timer for price quotes - Confirm receipt and provide a blockchain transaction link as a receipt - Support L2 networks for better fees and speed - Offer stablecoin options to reduce volatility Use Cases: Digital goods, cross-border sales, subscriptions with smart contracts, and marketplaces can leverage Ethereum payments for programmable and borderless commerce.
