On smart-contract-enabled chains, a Full node keeps recent state; an Archive node adds all historical state from genesis. Bitcoin has no per-block historical state — chain state is the UTXO set, derived from the chain itself — so there is no separate Archive class. Chainstack Bitcoin nodes are non-pruned with
txindex enabled: every block and every transaction from genesis is queryable. Full does not mean pruned.Historical address queries (transaction history, balance at a past block) need an indexer like electrs — available as a Bitcoin Dedicated Node customization. Contact us to enable it.Node mode describes data retention, not pricing. Requests are billed by request class — on some protocols every request bills as full even on archive-mode nodes. See Request units.
Sui nodes are full nodes carrying up to about 6 months of historical state, with transaction history back to genesis. Every Sui request is billed as full.
Chainstack also deploys bespoke Dedicated Nodes for chains not listed here. Contact us to discuss your chain.
