Arc Full Node: Complete Guide

What is a Arc full node?

A Arc full node syncs an execution client (and, where applicable, the L1/L2 stack behind it), verifies blocks, and serves standard Ethereum JSON-RPC: eth_blockNumber, eth_getBalance, eth_call, eth_getLogs, and eth_sendRawTransaction.

RpcNode offers managed Arc Full Node RPC over HTTPS so applications can read USDC balances, simulate contracts, and submit signed transactions without self-hosting Erigon/Geth and companion services.

Why Arc full nodes matter

Every wallet balance, payment confirmation, and contract read ultimately depends on nodes that agree on Arc state. Public endpoints rate-limit and flake; your product’s reliability tracks the quality of the full nodes behind your RPC URL.

• API family: EVM JSON-RPC

When to run your own Arc node

Self-hosting a Arc full node makes sense when you need custom indexing, ultra-low latency next to your app, or compliance constraints that forbid third-party RPC. For most product teams, managed Full Node RPC is faster to ship and cheaper to operate.

• Building wallets, payments, or address watchers that need reliable Arc reads and writes
• Avoiding multi-terabyte disks, peer tuning, and 24/7 pager duty for chain upgrades
• Preferring HTTPS JSON-RPC with allowlists, keys, and usage metering
• Evaluating Arc before dedicating hardware — start on RpcNode, or self-host with Toolkit in a few clicks

Arc full node server requirements

Arc full node server requirements follow typical EVM patterns: Geth, Reth, Erigon, or a chain-specific geth fork for execution. If the chain is post-merge Ethereum-like L1, budget a consensus client too.

Size minimum specs for a pruned/full node first. Archive hardware requirements are a different purchase — often 10+ TB NVMe.

Looking up "Arc server requirements", "Arc hardware requirements", or "Arc minimum specs"? Use the checklist below as the planning baseline for a self-hosted full node.

Arc is in the RpcNode catalog. Until you need custom indexing or on-prem constraints, prefer managed Full Node RPC when available rather than buying this class of server “just in case”.

• CPU: 4–8+ cores for snappy eth_call under load
• RAM: 16–32 GB common; 64 GB+ for heavier clients
• Disk: NVMe 1–2+ TB for full; archive is multi-TB
• Bandwidth: 1 Gbps recommended for peers + RPC
• OS: Ubuntu 22.04/24.04 LTS
• Full vs archive: RpcNode positions as Full Node RPC, not archive

Self-host Arc with RpcNode Toolkit

RpcNode Toolkit is a free self-hosted panel: install a Linux host agent, add the server, then add a node in a few clicks (network → environment → server). The node page walks install, sync, logs, and RPC.

Arc may already be in the Add node catalog, or you can use managed Full Node RPC on RpcNode while you wait. Hardware requirements in this guide still apply — Toolkit automates the install, not the disks.

1. Install the host agent on Linux, then Add server in the panel.
2. Add node: pick the network, environment, and server.
3. Open the node page for ports, install, sync, and the fullnode RPC endpoint.

How to run a Arc full node

How to run a Arc full node (EVM family): install the chain’s supported execution client (Geth/Reth/Erigon or a fork / L2 stack), configure a non-archive full profile, and expose JSON-RPC only through an allowlisted proxy.

If Arc is a post-merge L1 style network, run a consensus client beside execution with a shared JWT.

Arc is in the RpcNode catalog. Until you need custom indexing or on-prem constraints, prefer managed Full Node RPC when available rather than buying this class of server “just in case”.

1. Provision Ubuntu 24.04 LTS (or the OS your client documents) on bare metal or a dedicated VM. Create a system user such as `nodeop` — do not run the node as root.
2. Attach NVMe sized for full (non-archive) growth. Mount it away from the root filesystem and give ownership to the operator user.
3. Apply OS hygiene: unattended-upgrades or a patch cadence, fail2ban/SSH keys, and raise file-descriptor limits if the client docs require it.
4. Install the official or widely supported Arc client(s) from upstream releases — pin versions and read release notes before upgrades.
5. Configure full-node sync/pruning defaults suitable for tip RPC. Do not enable archive unless you need deep historical state.
6. Bind HTTP JSON-RPC to localhost (commonly `8545`); keep Engine/auth APIs local.
7. Create systemd services with automatic restart and log rotation.
8. Open only the documented P2P ports publicly; whitelist RPC.
9. Verify with `eth_syncing` / `eth_blockNumber` (or the chain’s equivalent) against a public explorer tip.

• Target: full node RPC, not validator keys (unless you intentionally stake)
• Confirm exact flags in official docs — chain forks differ

Using Arc RPC without self-hosting

RpcNode exposes managed EVM JSON-RPC for Arc. Create an endpoint in the cabinet, restrict IPs if needed, and call the same methods your stack already uses.

Catalog environments for Arc: Testnet. Create an endpoint in the RpcNode cabinet for the environment you need, or use this guide to plan a self-hosted deployment.

Typical methods teams start with: eth_blockNumber, eth_getBalance, eth_call, eth_getLogs, eth_sendRawTransaction.

Self-hosting vs managed Full Node RPC

Self-hosting gives maximum control and can reduce per-request cost at huge scale, but you own upgrades, peers, disk growth, and incident response. RpcNode Toolkit cuts the install to a few clicks (agent → Add server → Add node → node page) while you still run the hardware.

Managed RpcNode Full Node RPC trades that ops burden for a stable HTTPS endpoint, usage visibility, and the same method surface your SDK already speaks. If you are comparing providers, also see RpcNode’s comparison page.

Arc integration checklist

Use this short checklist when wiring Arc into production.

• Pick the correct environment (Testnet) — never mix testnet keys with mainnet funds
• Store RPC URLs and keys in secrets management; rotate on staff changes
• Add IP allowlisting for server-side backends
• Alert on tip lag / getHealth (or equivalent) failures
• Load-test eth_getLogs / getProgramAccounts-style heavy calls before launch
• Decide full vs archive needs early — RpcNode is Full Node oriented
• Confirm Arc server requirements (CPU/RAM/disk) before self-hosting
• Or install with RpcNode Toolkit in a few clicks — free self-hosted panel
