Swap Ethereum to Solana

Every Solana transaction has a fee payer: an ordinary wallet account that must hold enough SOL to cover the fee (Solana documentation). Sending a token, using an app and even the first transfer out of a new wallet all depend on it. When your crypto sits on Ethereum as ETH, this order turns part of it into SOL at your Solana address in one step, without an exchange account and without a bridge.

It also suits moving a larger position from Ethereum to Solana. Orders run from about $10 to $10,000,000 in value, and a fixed rate shows the exact SOL amount before you send anything, so you know what arrives while the ETH is still in your wallet.

Once the SOL is there, you can hold it, spend it on fees or swap it onward from the same wallet: SOL to BTC pays bitcoin on the Bitcoin network, and SOL to XMR pays Monero.

A bridge moves a token from one chain to another; it does not change what the token is. ETH bridged to Solana arrives as a token that stands for ETH, usually backed by coins locked on Ethereum, and it carries the bridge’s own risks (the guide to wrapped and native crypto covers them). To end up with SOL, you would then trade that token on Solana, which is another transaction with a fee payer that needs SOL. An empty wallet has none, so unless the app pays that fee for you, you need SOL to get SOL. Some bridges also ask for a claim transaction on the destination chain first.

This order is one ordinary ETH transfer. You do not connect a wallet to a website or sign anything on Solana, and any wallet or exchange withdrawal can pay the deposit. What arrives is native SOL, the coin that pays the fees, so the wallet is ready to use. A bridge still makes sense when you want ETH itself on Solana for an app that uses it. Some cross-chain services put a bridge and a swap behind one screen; before using one, check which token it delivers and who pays the Solana fee.

The two sides of this pair use unrelated address families. Ethereum builds an address from a public key made with the Elliptic Curve Digital Signature Algorithm: the last 20 bytes of its Keccak-256 hash, written as 0x and 40 hex characters (ethereum.org). A Solana wallet address is an Ed25519 public key, a 32-byte value displayed as a base58 string (Solana documentation). A wallet that supports both chains therefore keeps a separate account for each and shows two different addresses, and neither one works in place of the other.

In plain words, a Solana address:

• uses only letters and digits, with no 0x and no network prefix of any kind;
• never contains the digit 0, a capital O, a capital I or a lowercase l, which base58 leaves out because they are easy to confuse;
• is 32 to 44 characters long, and a wallet address is almost always 43 or 44;
• treats upper and lower case as different characters, so a single changed letter is a different address.

The payout field checks that what you paste decodes to a 32-byte Solana address, and when it recognises another format, such as an EVM (0x…) address, it names that network and asks for a Solana one. What it cannot see is what kind of account sits behind a valid address. A token account, a token mint and a program derived address, which has no private key at all, look just like a wallet address. Copy the payout address from your wallet’s Receive screen rather than from a block explorer page. A payout cannot be recalled once it is broadcast (Terms, section 11).

Every account on Solana must hold a minimum balance, proportional to the data it stores, to stay on-chain. The runtime still calls it the rent-exempt minimum, but ongoing rent collection is disabled, and the documentation describes it as a refundable storage deposit. The formula is (data size + 128 bytes) × 3,480 lamports per byte-year × 2 years. An ordinary wallet stores no data, so its minimum is 128 × 3,480 × 2 = 890,880 lamports, or 0.00089088 SOL, at 1,000,000,000 lamports to the SOL.

A brand-new address has no account yet. Sending SOL to it for the first time creates one, owned by the System Program, and all new accounts must be rent-exempt. The smallest Ghostex order pays out many times that minimum, so an empty wallet you have never used can take the payout. You do not need to hold SOL beforehand, and Ghostex pays the fee for sending it.

The rule matters when you send the SOL on. A balance may drop to exactly zero or stay at or above the minimum, but it cannot end anywhere in between: a transfer that would leave, say, 0.0005 SOL behind fails with an insufficient-funds-for-rent error (account runtime). Either keep at least 0.00089088 SOL in the wallet or empty it completely. Each transfer also costs a base fee of 5,000 lamports per signature (Solana fees), plus any priority fee your wallet adds.

Tokens are the other reason to keep some SOL. To receive an SPL token such as USDC, a wallet first needs a token account for it, and creating one takes a small amount of SOL to make it rent-exempt (Solana token program).
