The Problem With Skipping the Setup Solana has no account recovery system. No support ticket, no "forgot password" flow, no custodian holding a backup. When you create a self-custody wallet, you become the sole keyholder. Skip one step during setup and the consequences are permanent. This post covers the setup correctly, with the on-chain mechanics that matter. Pick a Wallet App The three wallet apps most Solana devs and traders actually use: Phantom: browser extension and mobile app, broad dApp support across the Solana ecosystem. Solflare: extension and mobile app, built for Solana from day…

You submit a swap transaction on Solana. No order book, no matching engine, no counterparty wallet. Your tokens hit a program holding reserves of two assets, and that program sends the other token back at a price calculated on the spot. Understanding what is a liquidity pool at this level explains most of what you see on a swap screen, including that price impact warning you might be ignoring. Two Token Reserves and One Formula A liquidity pool is an on-chain program account holding reserves of two tokens, say SOL and USDC. Any wallet can interact with it: deposit one token, receive the…

A token page can say anything. The mint account cannot lie. This post shows how to read a Solana token's real rules with one standard RPC call: no SDK, no wallet, no keys. We use it every Monday to re-check one token, and it recently corrected our own documentation. The one call: getAccountInfo with jsonParsed Every SPL token has a mint account. Ask any Solana RPC node for it with encoding: "jsonParsed" and the node decodes it for you: // read-mint.mjs · Node 18+ (built-in fetch) · read-only const MINT = process . argv [ 2 ] ; const RPC = process . argv [ 3 ] ||…

Most Solana tutorials still start the same way: install the CLI, make a keypair, run solana airdrop 2 . Run that against devnet today (CLI 4.2.2 here) and you get this: $ solana airdrop 2 8AKHUj5APsyeqDo2cFPmujtJSQyLRbXdhhYSpjhXm6A7 --url devnet Requesting airdrop of 2 SOL Error: airdrop request failed. This can happen when the rate limit is reached. The message blames a rate limit, so the natural move is to wait and try again later. For us it failed the same way a day later. We ran into this while funding test wallets for our own tools, and the cause turned out to be something waiting can't…
