Cronos node
A Cronos node of your own. EVM node or POS Chain validator.
Cronos is two chains that share a name. Our full node is a Cronos EVM node with a private JSON-RPC endpoint and no public batch cap. Our validator runs on the Cronos POS Chain, the one with an open validator set. A backup node sits beside yours.

02Full or validator
Two Cronos chains, two plans.
Cronos EVM runs smart contracts and has an invitation-only validator set. The Cronos POS Chain is a separate chain where CRO is staked, and anyone can try to become a validator.
Full node
$139/mo
- Chain
- Cronos EVM, chain ID 25. CRO pays the fees
- Does
- Follows the chain and answers EVM JSON-RPC calls, with CometBFT RPC, REST and gRPC listed beside it on the public endpoint list
- Keeps
- At default pruning the Cronos docs say about 1 TB. A pruned node of about 50 GB is only possible with state sync
- Archive
- Not offered yet. The docs measure about 6 TB with LevelDB or about 4.5 TB with RocksDB
Validator
$159/mo
- Chain
- Cronos POS Chain, a separate Cosmos SDK chain used mainly for staking CRO. It was the Crypto.org chain
- Does
- Signs POS Chain blocks under your key, with CRO bonded from a wallet you control
- Not sold
- A Cronos EVM validator. The Cronos FAQ says those are by invitation only and applications are not open
- Rules
- Slashing, unbonding and how many validators are active are on-chain settings, and guides disagree on them. Read the Cronos FAQ and the live chain before you stake
- Key
- The key sits on a single server. The backup node next to it carries none, so it can never be the second signer
The one-line test
Do you call smart contracts, wallets or payments on Cronos? Take the full node, which is Cronos EVM. Do you want to stake CRO and sign blocks? Take the validator, which is the POS Chain.
03How it works
Inside a Cronos EVM node.
It is a Cosmos node that also speaks Ethereum. Two programs share the server.
CometBFT
Agrees on each block with the other Cronos nodes.
cronosd
Applies the block, runs the EVM and keeps state. It is Ethermint on the Cosmos SDK.
Local link
The two parts share one server and talk directly.
Your endpoint
EVM calls and the Cosmos endpoints answer at one private nodes.herorpc.com URL, protected by your key.
Cronos EVM is a Cosmos node with Ethereum built in. Wallets use the EVM side, staking tools use the Cosmos side.
The free public endpoint caps batch calls at three items on mainnet. The Cronos docs tell larger users to run a dedicated node.
The docs list several fast-sync routes: native snapshots, Quicksync, state sync and others, so a first sync need not start at block one.
04Know the field
LevelDB or RocksDB: the choice behind the numbers.
The Cronos docs give two sets of memory and archive sizes, depending on the database a node uses.
Approximate sizes from the Cronos hardware page. Quicksync snapshots keep growing. We sell the default pruning node only.

Public endpoint batch cap
Mainnet runs cronosd 1.7.x. Read in October 2026. The POS Chain validator has its own node software, and its hardware is not covered here.

05Cronos, specifically
Six Cronos facts before you pick a plan.
From the Cronos docs and the Cronos FAQ. The first two decide which plan fits you.
Two chains, one name
Cronos EVM is chain ID 25. The Cronos POS Chain is a separate Cosmos SDK chain, mainly for staking CRO. The Cronos FAQ has a section on the difference.
EVM validators are invitation only
The Cronos FAQ says new applications are not open. It counts 33 validators, but the FAQ carries no date, so that count may be old.
Three calls per batch
The public endpoint evm.cronos.com accepts batches of 3 on mainnet and 5 on testnet. Larger batches need a dedicated node or a commercial provider.
Database sets the memory
The Cronos hardware page lists 32 GB of memory for LevelDB and 64 GB for RocksDB, and a smaller archive with RocksDB.
Many ways to sync
Native snapshots, Quicksync, state sync, KSYNC, VersionDB, MemIAVL and local state sync all appear in the Cronos docs.
Free limits push you to your own
The Cronos FAQ suggests setting up your own full node when you outgrow the free rate limit.
06Who rents one
Why teams rent one.
Teams that hit the public endpoint's limits, and operators who want to stake CRO.
DeFi and wallet teams
Send big batches of calls without the three-item cap, and keep your traffic off shared infrastructure.
Payment processors
Check CRO and token deposits on a node that only your systems use.
Explorers and indexers
Read blocks, receipts and logs from a node of your own. Every node price is on one page.
POS Chain validator operators
Host the signing node of a POS Chain validator, with CRO bonded from your own wallet.
07Price check
The Allnodes price, bar and card.
The full node bar sits against an Allnodes Cronos plan. Allnodes shows one Cronos validator plan on both its EVM and POS Chain pages, so that price is a card, not a bar.
Full node
Allnodes: the cheapest dedicated plan on its Cronos pricing page.
Allnodes, Cronos validator
Its POS Chain page lists the same plans as its EVM page, so it does not say which chain the plan serves.

10Questions
Cronos node questions
Real questions from node operators, answered plainly.
What is the difference between Cronos and the Cronos POS Chain?
Cronos EVM is the smart contract chain, chain ID 25. The Cronos POS Chain is a separate Cosmos SDK chain used mainly for staking CRO. Each has its own validators.
Can I run a validator on Cronos EVM?
Not by applying. The Cronos FAQ says validators there are by invitation only and applications are not open. We do not sell one.
Which validator do you sell?
A Cronos POS Chain validator. Slashing, unbonding and the number of active seats are chain settings, so read the Cronos FAQ and the live chain before you stake.
Why does the public Cronos RPC reject my batch?
The public endpoint caps batch requests at 3 items on mainnet. The Cronos docs say to use a dedicated node or a commercial provider for more.
What are the Cronos node requirements?
The Cronos hardware page lists a 4-core CPU, with 32 GB of memory for LevelDB or 64 GB for RocksDB. Disk is about 1 TB at default pruning.
How big is a Cronos archive node?
About 6 TB with LevelDB or about 4.5 TB with RocksDB, per the Cronos docs. We do not offer archive yet.
Which database should a node use?
LevelDB needs less memory, and RocksDB needs a bigger server but a smaller archive. The docs list both without picking one.
Is the backup node safe next to a validator?
Yes. Only the primary server ever has the key, so the backup cannot add a second signature.
What does it cost?
Cronos EVM full: $139 monthly. POS Chain validator: $159 monthly. Setup is free, and a 12-month prepay trims 25 percent.
How quickly is it ready?
Inside 24 hours of payment. The URL and the login details show up in your dashboard when it is ready.
Past the three-call cap.
EVM full node $139, POS Chain validator $159. Paid by the month, and a spare node is part of it.
