Solana's DeFi and perpetuals markets are having a loud summer, and Backpack Exchange sits at the center of it: SOL perpetual contracts (perps) traded with razor-sharp latency, near-zero gas fees, and real-time execution. Behind that speed is an infrastructure layer doing quiet, unglamorous work: NoLimitNodes.
This post covers two things. First, why NoLimitNodes has become the RPC provider of choice for serious traders and developers. Second, a working reference to the full range of Solana JSON-RPC methods the platform supports.
Why NoLimitNodes Powers the Fastest Traders on Solana

Solana's performance depends heavily on RPC providers, the gateways through which applications talk to the blockchain. NoLimitNodes offers:
- Ultra-low latency access to Solana RPC endpoints
- High-availability infrastructure, even during congestion
- DDoS protection and failover systems to ensure zero downtime
- Complete RPC method support for advanced developers and dApps
Trading on Backpack Exchange or building the next high-frequency trading bot, NoLimitNodes gives you the edge.
Solana JSON-RPC APIs Worth Knowing, With Explanations
Here's a curated list of essential Solana APIs in plain terms, for developers, traders, and builders. Bookmark it; you'll come back to it.

Account & Transaction Methods
getAccountInfo– Returns full data about a wallet or smart contract account using its public key.getBalance– Fetches the lamport (SOL) balance of a given public key.getTokenAccountBalance– Returns the balance of a specific SPL token account.getMultipleAccounts– Retrieves data for several accounts in one call.getTransaction– Gives detailed metadata and status of a confirmed transaction using its signature.getSignaturesForAddress– Lists recent transaction signatures related to an address.getSignatureStatuses– Checks whether recent transactions succeeded or failed.
Block & Slot Methods
getBlock– Returns all transactions and metadata for a given confirmed block.getBlockTime– Estimates the timestamp when a particular block was confirmed.getBlockHeight– Reports the current block height, which you'll want for syncing.getBlocks/getBlocksWithLimit– Lists all confirmed blocks between slots or within a range.getBlockCommitment– Shows stake weight behind a block, useful for analyzing finality.
Epoch & Leader Info
getEpochInfo– Tells you the current epoch, slot index, and total slots in the epoch.getEpochSchedule– Describes how long each epoch lasts and when epoch changes occur.getLeaderSchedule– Shows which validators are scheduled to produce blocks in the current or next epoch.getSlot– Returns the current slot processed by the node.getSlotLeader– Reveals the validator responsible for the current slot.getSlotLeaders– Lists the validators responsible for producing blocks over a slot range.
Validator & Cluster Information
getClusterNodes– Shows a list of all known validator nodes in the cluster.getIdentity– Returns the public key identity of the node you're querying.getVoteAccounts– Fetches stake and identity data for validators participating in consensus.getInflationGovernor– Returns the rules for Solana's inflation model.getInflationRate– Shows the current inflation rate per epoch.getInflationReward– Retrieves staking rewards for a list of validator or wallet addresses.
Token & Supply Management
getTokenAccountsByOwner– Lists all SPL token accounts owned by a specific wallet.getTokenAccountsByDelegate– Lists SPL token accounts where another wallet is a delegate.getTokenLargestAccounts– Shows the top holders of a specific SPL token.getTokenSupply– Returns the total circulating supply of an SPL token.getLargestAccounts– Reveals the largest SOL holders (by lamport balance).getSupply– Breaks down SOL's total, circulating, and non-circulating supply.
Utility & Development APIs
getLatestBlockhash– Fetches the latest valid blockhash to build and sign transactions.isBlockhashValid– Confirms whether a given blockhash is still valid.getMinimumBalanceForRentExemption– Calculates the minimum SOL needed to exempt an account from rent.getGenesisHash– Returns Solana's genesis block hash, a unique identifier for the chain.getVersion– Returns the software version of the Solana node.getRecentPerformanceSamples– Gives TPS (transactions per second) data over time.getTransactionCount– Reports the total transaction count from the ledger.getRecentPrioritizationFees– Helps fee-payers decide how to prioritize their transactions.
Transaction & Airdrop Methods
sendTransaction– Sends a signed transaction to the cluster for confirmation.simulateTransaction– Dry-runs a transaction without submitting it.requestAirdrop– Requests SOL (on devnet/testnet) for testing dApps or wallets.
System Info & Health
getHealth– Returns a simple health check for the node.getHighestSnapshotSlot– Shows the highest available snapshot the node has saved.getMaxRetransmitSlot/getMaxShredInsertSlot– Technical insight into node progress and performance.minimumLedgerSlot– The lowest slot the node retains in its local ledger data.
