Frequently Asked Questions

LayerPay charges a flat 1% platform fee per transaction. This is automatically deducted by the smart contract at the time of payment.

There are no setup fees, monthly fees, or minimum volume requirements.

Additionally, customers pay blockchain network fees (gas), which vary by network:

• Base/Optimism/Arbitrum: ~$0.01
• Ethereum mainnet: ~$1-5

Payments are sent directly to your Ethereum wallet address. You just need to provide your wallet address (0x...) in the plugin settings.

The funds arrive immediately after the blockchain confirms the transaction - typically within seconds on Layer 2 networks.

There's no withdrawal process or waiting period. The crypto is yours instantly.

Any Ethereum-compatible wallet works. Popular options include:

• MetaMask
• Coinbase Wallet
• Trust Wallet
• Ledger/Trezor hardware wallets
• Any wallet that gives you an Ethereum address (0x...)

Important: Make sure you control the private keys. Don't use exchange deposit addresses.

Customers can pay with 300+ wallets via two connection methods:

• MetaMask: Direct browser extension connection
• WalletConnect: QR code that works with mobile wallets like Trust Wallet, Rainbow, Coinbase Wallet, and many more

Layer 2 networks are scaling solutions built on top of Ethereum. They process transactions faster and cheaper while inheriting Ethereum's security.

LayerPay supports:

• Base: Built by Coinbase, lowest fees (~$0.001)
• Optimism: Wide adoption, established ecosystem
• Arbitrum: High liquidity, popular in DeFi

Customers need to have funds on the specific L2 network to pay with low fees.

LayerPay uses real-time price data from multiple sources:

• CoinGecko API: ETH/USD price
• ExchangeRate API: EUR/USD conversion (if your store uses EUR)

A small buffer (default 2%) is added to the quoted price to account for volatility between quote and payment.

Your store can be in EUR or USD. The plugin automatically converts the order total to the equivalent amount in ETH or USDC.

For example, a €50 order would be quoted as approximately 0.014 ETH at current rates.

Blockchain transactions are irreversible by design. This eliminates chargeback fraud.

If you need to issue a refund, you would send crypto back to the customer's wallet address manually. The customer's address is recorded with each order.

Yes. LayerPay is designed with security as a priority:

• Non-custodial: We never hold your funds
• On-chain verification: Payments are verified by reading blockchain data directly
• Open source contracts: Smart contracts are verified and readable on block explorers
• No stored payment data: We don't store sensitive customer information

Yes! LayerPay includes a Test Mode that uses testnet networks:

• Sepolia (Ethereum testnet)
• Base Sepolia
• Optimism Sepolia
• Arbitrum Sepolia

You can get free testnet ETH from faucets to test the complete payment flow without real money.

If a blockchain transaction fails or the customer doesn't complete payment:

• The order remains in "Pending Payment" status
• No funds are transferred
• The customer can retry the payment

Failed blockchain transactions may still cost the customer gas fees (network fees), but no payment is made to you.

No. LayerPay is a self-hosted plugin. You download it, install it on your store, and configure your wallet address. That's it.

There's no account creation, KYC verification, or approval process required.
