# Connect validator to X1 Mainnet ## Step 1 — Switch RPC to X1 Mainnet Set your Solana CLI to use the X1 Mainnet endpoint: ```bash solana config set --url https://rpc.mainnet.x1.xyz ``` *** ## Step 2 — Verify Validator Airdrop Check that your `id.json` or hardware wallet public key has received the validator airdrop: ```bash solana balance ``` Your balance should be **greater than 0**. *** ## Step 3 — Fund Local Keypairs Send **1 XNT** (or a small amount) to both: * `id.json` — used to manage startup of the validator * `identity.json` — your validator identity key Do this using **Backpack Wallet**. {% hint style="info" %} To switch Backpack to Mainnet RPC:\ {% endhint %} {% hint style="info" %} To import your hardware wallet in Backpack:\ Wallets → **Add new Solana wallet** → **Hardware wallet** {% endhint %} *** ## Step 4 — Configure Solana CLI Identity Make sure you’re operating with the correct signer: ```bash solana config set -k ~/.config/solana/id.json ``` Check balances: ```bash solana balance ~/.config/solana/id.json solana balance ~/.config/solana/identity.json ``` *** ## Step 5 — Go to Your Keypair Directory Navigate to where your keypair files are stored: ```bash cd ~/.config/solana ``` *** ## 6. Create a Vote Account Create a **vote account** for `vote.json`, and assign your **hardware wallet (Ledger)** as the **withdraw authority**. *** ### 6.1 Get Your Ledger’s Public Key (on Your Local Machine) On your **local computer**, plug in your **Ledger**, open the **Solana app**, and run: ```bash solana-keygen pubkey "usb://ledger?key=0/0" ``` Copy the output — this is your **Ledger withdraw authority address**: ``` ``` > 💡 You only need the **public key** from your Ledger.\ > The Ledger does **not** need to be connected to your validator server. *** ### 6.2 Create the Vote Account (on Your Validator Server) Create a vote account for `vote.json`, using your `identity.json` keypair as the signer, and set your Ledger pubkey as the withdraw authority: ```bash solana create-vote-account vote.json identity.json --commission 10 ``` * `identity.json` → signs the vote account creation and becomes the validator identity * `` → becomes the withdraw authority * `--commission 10` → your validator keeps **10%**, and **delegators receive 90%** *** ### 6.3 Verify the Vote Account Confirm it was successfully created: ```bash solana vote-account ``` You should see details such as: * Identity pubkey * Withdraw authority * Commission % * Epoch credits and status *** ## Step 7 — Create a Stake Account Create a stake account and deposit a small amount (e.g. 0.1 XNT): ```bash solana create-stake-account stake.json 0.1 ``` This initializes `stake.json` using funds from your `id.json`. *** ## Step 8 — Secure Stake Account with Hardware Wallet Authorize your Ledger hardware wallet as the **withdraw authority**: ```bash solana stake-authorize stake.json --new-withdraw-authority ``` Now only your hardware wallet can withdraw or modify the stake account. *** ## Step 9 — Fund Your Stake Account Send more XNT to your stake account from your hardware wallet using Backpack. **In Backpack:** * **From:** your hardware wallet pubkey * **To:** your `stake.json` pubkey * **Amount:** the amount you want to stake to your validator Verify balance: ```bash solana balance ~/.config/solana/stake.json ``` *** ## Step 10 — Delegate Stake Link your stake account to your vote account: ```bash solana delegate-stake stake.json vote.json ``` This command delegates your staked XNT to your validator’s vote account. *** ## Step 11 — Check Stake Account Status View your stake account details: ```bash solana stake-account stake.json ``` Example output: ``` Balance: 100.1 XNT Rent Exempt Reserve: 0.00228288 XNT Delegated Stake: 100.0 XNT Active Stake: 0 XNT Activating Stake: 100.0 XNT Stake activates starting from epoch: 9 Delegated Vote Account Address: Stake Authority: Withdraw Authority: ``` > The stake will become active starting from the listed epoch once the validator is participating in consensus. *** ## Step 12 — Reset Local Ledger Before switching to mainnet, clear your old testnet ledger to avoid conflicts: ```bash rm -rf ~/ledger ``` *** ## Step 13 — Update Validator Startup Script for Mainnet Open your validator startup script: ```bash nano $HOME/bin/validator.sh ``` Replace its contents with: ```bash #!/bin/bash export RUST_LOG=solana_metrics=warn,info exec tachyon-validator \ --identity $HOME/.config/solana/identity.json \ --vote-account $HOME/.config/solana/vote.json \ --entrypoint entrypoint0.mainnet.x1.xyz:8001 \ --entrypoint entrypoint1.mainnet.x1.xyz:8001 \ --entrypoint entrypoint2.mainnet.x1.xyz:8001 \ --entrypoint entrypoint3.mainnet.x1.xyz:8001 \ --entrypoint entrypoint4.mainnet.x1.xyz:8001 \ --known-validator 7ufaUVtQKzGu5tpFtii9Cg8kR4jcpjQSXwsF3oVPSMZA \ --known-validator 5Rzytnub9yGTFHqSmauFLsAbdXFbehMwPBLiuEgKajUN \ --known-validator 4V2QkkWce8bwTzvvwPiNRNQ4W433ZsGQi9aWU12Q8uBF \ --known-validator CkMwg4TM6jaSC5rJALQjvLc51XFY5pJ1H9f1Tmu5Qdxs \ --known-validator 7J5wJaH55ZYjCCmCMt7Gb3QL6FGFmjz5U8b6NcbzfoTy \ --only-known-rpc \ --log $HOME/validator.log \ --ledger $HOME/ledger \ --rpc-port 8899 \ --full-rpc-api \ --dynamic-port-range 8000-8020 \ --wal-recovery-mode skip_any_corrupted_record \ --limit-ledger-size 50000000 \ --enable-rpc-transaction-history \ --enable-extended-tx-metadata-storage \ --rpc-pubsub-enable-block-subscription \ --full-snapshot-interval-slots 5000 \ --maximum-incremental-snapshots-to-retain 10 \ --maximum-full-snapshots-to-retain 50 ``` Save and exit the editor. *** ## Step 14 — Start the Validator From your home directory: ```bash cd $HOME nohup $HOME/bin/validator.sh & ``` *** ## Step 15 — Monitor Your Validator Check validator logs: ```bash tail -f $HOME/validator.log ``` Check catch-up status: ```bash solana catchup --our-localhost ``` Monitor validator performance: ```bash tachyon-validator --ledger ./ledger monitor ```
