First-run setup: sithbit setup

sithbit setup

A guided, re-runnable first-run wizard. It configures the two things every other command depends on — a Solana RPC endpoint and a signing keypair — using plain stdin prompts, makes sure the wallet can afford a mailbox, can optionally claim your on-chain mailbox in the same pass, and then points you at the next steps. It takes no flags: everything is driven by the dialogue.

It is deliberately non-destructive. It reads your current config values up front and shows them, writes a change only when you type an explicit new value (pressing Enter keeps the current one), and confirms before generating a wallet — so re-running it on an already-configured machine, or against a funded keypair, never clobbers anything. The one exception to “Enter changes nothing” is a brand-new machine: when no wallet exists yet the wizard suggests a default endpoint, and pressing Enter accepts and writes that suggestion. The one step that spends SOL and sends a transaction — the mailbox create — defaults to no, so a piped or closed stdin never fires it by accident.

The wizard runs five steps:

1. RPC endpoint. Shows the currently configured endpoint. Enter a new URL to switch clusters (this writes the same config sithbit config set --url edits), or press Enter to keep the current one. On a machine with no wallet yet, the wizard instead suggests a build-appropriate default — mainnet for release builds, devnet for development builds — and Enter accepts and persists the suggestion. (The two endpoint constants live at the top of mail_client/src/commands/setup.rs, so an operator shipping a hosted RPC endpoint swaps them in one place.)
2. Signing keypair. Shows the current keypair path and lets you change it. If no readable keypair exists at the chosen path, it offers to generate a fresh wallet there (the same artifact sithbit wallet create writes). It asks first, so a re-run never overwrites an existing wallet; decline and it prints the manual sithbit wallet create command instead.
3. Wallet funding. Checks that the settled wallet — freshly generated or pre-existing — holds enough SOL to pay for a mailbox create (the account rents, the flat alias fee, and a small fee buffer; about 0.0124 SOL). A wallet that already covers it, or that already owns a mailbox, skips the step with a note. Otherwise, on clusters with a faucet (devnet, testnet, a local validator) the wizard requests an airdrop of one SOL, retrying a few times because the public devnet faucet is flaky; on mainnet — or if the faucet stays dry — it prints your wallet address and the required amount, re-checks the balance each time you press Enter, and lets you type skip to move on unfunded. (The devnet web faucet at faucet.solana.com is the manual fallback when the RPC faucet errors.)
4. Mailbox. Offers to claim your on-chain mailbox right now, defaulting to skip (only an explicit y/yes proceeds). Accept and it prompts for the mail domain (default sithbit.com) and the default stamp price in lamports (default one SOL), then drives the same on-chain create as sithbit mailbox create — which also mints the wallet’s self-alias in the same transaction. It is re-run-safe: a create against a mailbox that already exists errors on-chain, and the wizard surfaces that message and carries on to completion rather than aborting. Decline and it prints the manual sithbit mailbox create command instead.
5. Next steps. Static guidance — create your on-chain mailbox (if you skipped step 4), set a default stamp price, and review your settings with sithbit config get.

Example

A first run on a machine with no wallet yet, switching to devnet, letting the wizard generate a keypair, fund it from the faucet, and claim a mailbox inline:

$ sithbit setup
SithBit setup — configure your RPC endpoint and wallet.
Config file: /home/you/.config/solana/cli/config.yml

Step 1/5  RPC endpoint
  Current: https://api.mainnet-beta.solana.com
  New URL (Enter keeps current): https://api.devnet.solana.com
  Set RPC endpoint to https://api.devnet.solana.com.

Step 2/5  Signing keypair
  Current: /home/you/.config/solana/id.json
  No keypair file found at /home/you/.config/solana/id.json.
  Generate a new wallet there now? [Y/n]: y
  Generated a new wallet at /home/you/.config/solana/id.json.

Step 3/5  Wallet funding
  Requesting 1000000000 lamports (1 SOL) from the cluster faucet…
  Airdropped 1000000000 lamports (1 SOL).

Step 4/5  Mailbox
  A mailbox is your on-chain inbox — claim one to start receiving mail.
  Create your mailbox on-chain now? [y/N]: y
  Domain [sithbit.com]:
  Default stamp price in lamports [1000000000]:
  Created your mailbox for domain sithbit.com.

Step 5/5  Next steps
  You're configured. To start receiving mail:
    1. sithbit mailbox create   # claim your on-chain mailbox
    2. sithbit mailbox update   # set your default stamp price
    3. sithbit config get       # review your settings anytime

Done.

On mainnet the funding step has no faucet to lean on, so a wallet short of the mailbox cost is shown its own address and the amount to send, and the wizard re-checks the balance each time you press Enter:

Step 3/5  Wallet funding
  Creating a mailbox costs about 12415720 lamports (0.01241572 SOL).
  Send at least that much to your wallet address:
    85FZrun1Eb5bdkbFCDjaFSTLnBfnx6sUFHa5BiYH2Q03
  Press Enter to re-check the balance, or type 'skip':

If a keypair already exists at the chosen path the wizard reports Found an existing keypair at … and skips generation entirely; a wallet that already holds enough SOL passes the funding step with a one-line note, and one that already owns a mailbox skips both the funding wait and the create prompt. Declining the mailbox step (the default) prints Claim one later with: sithbit mailbox create and moves on, and re-running the wizard against a wallet that already owns a mailbox prints You already have a mailbox — skipping. and still finishes. The prompts also default cleanly on end-of-input, so a piped or closed stdin takes every default — including skipping the funding wait and the mailbox create — rather than hanging.
