Accepting ETH means receiving the network’s native coin, while accepting USDC or DAI on Ethereum means receiving a token transfer. Both can use an EVM address, but their transaction evidence and customer instructions differ. The asset and network must remain explicit.
Choose the actual ETH network
Coinvay supports native ETH on Ethereum and Base when those routes are enabled. Ethereum mainnet ETH and Base ETH are balances on different chains. An identical-looking receiving address does not make a transfer on one chain settle an invoice on the other.
For example, a development agency may let a client choose ETH on Base. Checkout then quotes a precise amount for that route. The client should not send Ethereum-mainnet ETH because an old invoice or copied address used the same hexadecimal account.
Leave room for the sending fee
A native ETH sender needs enough ETH to cover both the quoted transfer and the transaction fee. A wallet’s Send Max option may subtract fees and produce an amount that does not match the invoice. Review the recipient amount before approval.
Fees vary, so a page should not promise a fixed gas price. For a small order, compare the practical cost of the chosen route before the buyer commits. Coinvay’s current zero invoice commission is independent of the network fee paid by the sender.
Recognize native transfer evidence
The verifier checks the transaction destination and native value, successful receipt, correct chain, time window and confirmation requirement. An ERC-20 transfer event for an unrelated token is not evidence of an ETH payment. Similarly, a wrapped ETH token is different from native ETH unless a gateway explicitly supports it.
A merchant who receives ETH retains market-price exposure after payment. Pricing an invoice in USD does not cause the gateway to convert the receipt into dollars or guarantee the value of retained ETH.
Practical checklist
- Show Ethereum or Base beside ETH, not just a token logo.
- Check the recipient amount after accounting for gas.
- Keep native ETH and wrapped-token policies distinct.
Common questions
Can a customer pay with WETH instead of ETH?+
Not in a native ETH quote merely because the names are related. Wrapped ETH is a separate contract token. The checkout must explicitly support the exact asset being transferred.
Do ETH payments need spending approval?+
An ordinary native ETH transfer is approved as a transaction by the wallet holder. It is not an ERC-20 allowance. Any recurring-contract or token-approval flow should be described separately.
