SOL Memo
The fastest and most affordable way to engrave your words on-chain. Confirmed in seconds on Solana.
What is the Memo Program?
Solana has a built-in “Memo” program that lets anyone attach a text message to a transaction. It’s Solana’s native way of embedding human-readable data on-chain — simple, lightweight, and recognized by all major Solana explorers.
When you choose SOL Memo, EternalChain sends a Solana transaction with a Memo instruction containing your inscription as plain UTF-8 text. The memo is permanently stored in the transaction record on-chain.
How It Works
1. Your message is encoded as UTF-8 bytes.
2. EternalChain creates a Solana transaction with a Memo program instruction.
3. The transaction is sent to the Solana network and confirmed almost instantly.
4. Your inscription is visible on any Solana block explorer (Solscan, Solana Explorer).
How to Verify Your Inscription
On Solscan, your inscription appears directly in the “Instruction Data” section as readable text. You can also fetch it programmatically:
// Fetch the transaction from Solana
const res = await fetch("https://api.mainnet-beta.solana.com", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({
jsonrpc: "2.0", id: 1,
method: "getTransaction",
params: ["<txid>", { encoding: "jsonParsed" }]
})
});
const { result: tx } = await res.json();
// Find the Memo instruction
const memo = tx.transaction.message.instructions.find(
(ix) => ix.program === "spl-memo"
);
console.log(memo.parsed); // Your inscriptionCost
A SOL Memo engraving costs just $5 — the most affordable option. Solana’s transaction fees are a fraction of a cent, so the price is almost entirely for the engraving service. No wallet or SOL required.
Confirmation Time
Solana processes blocks roughly every 400 milliseconds. Your inscription is confirmed in seconds and reaches full finality in about 13 seconds — by far the fastest of any method EternalChain offers.
