How to Send and Receive ETH in a Non-Custodial Wallet

Sending and receiving ETH in IDX is designed to stay simple: open the wallet, pick Receive or Send, confirm the Ethereum address, and review gas before you sign. IDX is non-custodial — keys stay on your device — and pairs Ethereum with Solana, including cross-chain swaps when you need to move value between chains.

This guide covers same-network ETH send / receive. If you want Solana ↔ Ethereum value movement, use the in-wallet cross-chain swap (not a direct send to the other chain's address).

What you need before you start

• The official IDX Wallet browser extension or mobile app (see Chrome extension, Android app, or all download platforms) — simple UI for send, receive, and zero-fee swaps.
• A funded wallet on Ethereum, or someone ready to send you ETH.
• Enough ETH for gas if you plan to send or approve tokens — even small transfers require network fees.
• Your seed phrase backed up offline. If you lose it, nobody — including IDX — can restore the wallet. Read seed phrase backup basics.

How to receive ETH

1. Open IDX Wallet and select the account you want to fund.
2. Confirm you are looking at your Ethereum address (typically starts with 0x), not a Solana address.
3. Open Receive (or copy address / show QR from the account view).
4. Copy the address or share the QR code with the sender. Prefer copy / paste or QR — avoid typing addresses by hand.
5. Ask the sender to send on Ethereum (the same network your address is for). Wait for confirmation; timing depends on network congestion.

Your public address is safe to share. Your seed phrase and private keys are not — IDX support will never ask for them. See IDX Wallet Support & FAQs.

How to send ETH

1. Get the recipient's Ethereum address (starts with 0x). Confirm they expect funds on Ethereum — not Solana.
2. In IDX, choose Send, select ETH (or the asset), and paste the address carefully.
3. Enter the amount. Leave headroom for gas if you are sending close to your full balance.
4. Review the confirmation screen: recipient, amount, network, and estimated network fee.
5. Approve the transaction. Once confirmed on-chain, transfers cannot be reversed.

For a first transfer to a new address, many users send a small test amount first, then the remainder.

Need Solana ↔ Ethereum instead? Use cross-chain swap

A direct ETH send only works to an Ethereum address. To move value between Solana and Ethereum, use IDX's cross-chain swap in the same simple UI — select the source and destination assets/networks, review the quote (IDX is built for the lowest platform fees on swaps), then sign. Network and routing costs still appear in the quote.

Compare positioning with MetaMask in IDX vs MetaMask.

Ethereum gas fees (what you actually pay)

Gas is the network fee paid in ETH to process your transaction. A simple ETH transfer uses a fixed amount of gas units; the price of that gas (in gwei) moves with demand. Busy periods cost more; quieter periods cost less.

IDX's lowest platform fees (including zero platform fees on token-to-token swaps) do not mean free Ethereum gas. Platform fee and network fee are different. Always read the fee line before you sign.

Common mistakes that lose funds

• Sending ETH to a Solana address with Send (use cross-chain swap instead when you want to change chains).
• Assuming every 0x address is on the same network — ERC-20 tokens and ETH on different chains are not interchangeable. IDX focuses on Solana and Ethereum; do not assume every L2 works unless the product shows it.
• Typing addresses manually or trusting an address from an unverified chat.
• Approving unlimited token allowances to unknown contracts.
• Entering your seed phrase on a website that claims to “speed up” or “verify” a transfer.

Where this fits in self-custody

Non-custodial means you approve every send and swap yourself. That is the point of a non-custodial Solana and Ethereum wallet: control and responsibility travel together. For Solana-native ops like reclaiming rent, see close token account on Solana.
