Generate Solana wallets in bulk, right in your browser

A Solana wallet is an Ed25519 keypair. Its address is the 32-byte public key in base58, and its secret is the 32-byte seed the key was made from. The Solana CLI stores both together as a 64-byte array, seed followed by public key, which is the JSON file this tool downloads. Making a wallet needs nothing but 32 random bytes and one elliptic-curve computation; there is no registration, no network and no account to create until the address first receives SOL.

This page does exactly that in your browser. The random bytes come from crypto.getRandomValues, the operating system's cryptographically secure generator that browsers expose, the same source the Phantom extension uses. Generation runs on your device, the tab makes no network requests while generating, and you can load the page, disconnect from the internet and generate with the connection off. Each key is verified by re-deriving its public key from the secret before it is displayed.

Independent mode draws a fresh random seed for every wallet. No wallet is related to another, so a leaked key exposes exactly one wallet and you can hand single keys to single bots or team members without exposing the rest. The cost is that you have to store every key yourself; there is no phrase that recovers them all, and a lost JSON file means a lost wallet.

Seed phrase mode generates one BIP39 mnemonic of 12 or 24 words and derives the accounts from it at m/44'/501'/i'/0', the path Phantom, Solflare, Backpack and Ledger Live use for account i. Importing the phrase into any of those wallets shows the same addresses in the same order, which is convenient for a set of wallets you want to manage from one place. The trade-off is the reverse: whoever has the phrase has every account, now and in the future. The derivation follows SLIP-0010 and is checked against its published test vectors.

Bulk wallets are for operations: trading and sniper bots that each need their own signer, airdrop distribution wallets, test accounts for a program under development, burner wallets for mints and claims, and hot wallets that hold what a task needs for a day. For these the ability to create fifty addresses in a second and drop the JSON into a script matters more than hardware-grade isolation.

They are not a replacement for a hardware wallet. A browser tab is only as private as the device it runs on: a malicious extension or malware can read what a page shows and what you copy to the clipboard. Keep long-term holdings on a hardware wallet or a phrase written down offline. If you need a memorable address rather than many, the Vanity Address Generator searches for a prefix or suffix with the same key handling.

The per-wallet .json is the 64-number array solana-keygen writes, usable directly as --keypair in the Solana CLI or with Keypair.fromSecretKey in web3.js. The combined JSON is an array of those arrays in index order. The CSV holds the address and the secret in base58, which is the format Phantom and Solflare accept under Import private key; the seed phrase mode adds the derivation path column.

The addresses-only TXT is safe to share: it lists public keys, one per line, with nothing secret. Paste it into the Batch Balance Checker to watch the set, or into the Solana Multisender to fund every wallet with SOL for fees in one batch. Remember that a new address is empty until it receives SOL, and that a token account needs about 0.0015 SOL of rent the first time the wallet receives a given token.

The generator hands you a file and keeps nothing. To keep wallets in encrypted groups, then fund and sweep them, use the Wallet Manager.
