These are notes from the project's own docs and on-chain data as of Oct 9, 2026. Not financial advice.</p> <h2> What it is </h2> <p><a href="https://x7pad.com" rel="noopener noreferrer">x7pad</a> is a token launchpad on Solana built on Meteora markets. The twist: per the docs, every coin is paired with a tokenized stock (TSLAX is the docs' example) instead of SOL or a stablecoin. Standard mode pairs a coin with one stock; Basket mode pairs it with two to six. It's non-custodial, so every launch, buy, sell and claim is a transaction your own wallet approves.</p> <h2> Launching a coin (from the docs) </h2> <ol> <li>Connect a Solana wallet. Launching costs about 0.03 SOL.</li> <li>Pick the stock (or basket) your coin trades against.</li> <li>Choose a trading fee: 1%, 2% or 5%. It's fixed for life.</li> <li>Choose who receives the fee share: you, the holders, or another wallet.</li> <li>The coin opens near a 15K valuation, priced in the paired stock. A sniper fee starts at 90% and decays to your chosen fee within 5 seconds.</li> </ol> <h2> Where fees go (per the docs) </h2> <ul> <li>On every coin except $X7: 70% to the creator, holders or chosen wallet; 20% buys $X7 on the open market and burns it; 10% to the treasury.</li> <li>On $X7 itself: 80% buys and burns $X7; 20% to the treasury.</li> <li>Burns run from a dedicated buyback wallet roughly every hour.</li> </ul> <h2> Burn check </h2> <p>On-chain supply on Oct 9 read about 788.9M X7 against the original 1B, so roughly 211M (21.1%) is gone. The project's scoreboard (x7pad.com/revenue) reports $122.5K spent on buy-and-burn and 210.74M X7 burned across 303 runs. Those are the project's own figures, but the on-chain supply lines up.</p> <h2> Recent updates (from @x7pad) </h2> <ul> <li>Oct 6: Hooks went live.</li> <li>Oct 7: x7 Index launched; 20% of supply burned.</li> <li>Oct 8: custom pairs went live.</li> </ul> <h2> Things to know before touching it </h2> <ul> <li>Check the full mint: CdhZy8wrRxNxoV8HtoByXKN7mvS46avtuZ1b39tKfx7. Every x7pad coin ends in "x7", so the ending alone proves nothing, and there are many copycat "x7" tokens on pump.fun.</li> <li>Mint and freeze authority are revoked and the main pool is locked (per Rugcheck), but the team is anonymous and no audit is claimed.</li> <li>Tokenized stocks have their own eligibility rules depending on where you live.</li> <li>It's a small, volatile token. Do your own research.</li> </ul> <p>Official links: <a href="https://x7pad.com" rel="noopener noreferrer">https://x7pad.com</a> and <a href="https://x.com/x7pad" rel="noopener noreferrer">https://x.com/x7pad</a></p> solana blockchain web3 cryptocurrency Sheng Tsai Thu, 08 Oct 2026 21:14:27 +0000 https://dev.to/shengtsai/opcode-a-solana-terminal-for-109-tokenized-stocks-and-etfs-a-holders-notes-2pa0 https://dev.to/shengtsai/opcode-a-solana-terminal-for-109-tokenized-stocks-and-etfs-a-holders-notes-2pa0 <p><em>Disclosure: I hold $OP.
