标准 Solana RPC
所有标准 Solana RPC 方法都可以直接在helius.* 上通过对基础 @solana/kit Rpc 客户端的代理使用：
const balance = await helius.getBalance(address).send();
const blockhash = await helius.getLatestBlockhash().send();
const slot = await helius.getSlot().send();
helius.raw 显式公开相同的 Rpc 客户端，在传递给需要标准 Rpc 对象的第三方库时很有用。
DAS API（数字资产标准）
使用统一接口查询 NFT、压缩 NFT、同质代币和其他数字资产。helius.getAsset({ id }) // Single asset by mint
helius.getAssetBatch({ ids }) // Multiple assets
helius.getAssetsByOwner({ ownerAddress, page, limit }) // Assets by wallet
helius.getAssetsByAuthority({ authorityAddress }) // Assets by update authority
helius.getAssetsByCreator({ creatorAddress }) // Assets by creator
helius.getAssetsByGroup({ groupKey, groupValue }) // Assets by collection
helius.searchAssets({ ownerAddress, tokenType, ... }) // Flexible search
helius.getAssetProof({ id }) // Merkle proof (cNFTs)
helius.getAssetProofBatch({ ids }) // Batch Merkle proofs
helius.getTokenAccounts({ owner }) // Token accounts
helius.getNftEditions({ id }) // Print editions
helius.getSignaturesForAsset({ id }) // Transaction history for asset
RPC V2 方法
增强的 RPC 方法，支持服务器端分页、过滤和代币账户。helius.getTransactionsForAddress([address, config]) // Transaction history (paginationToken)
helius.getProgramAccountsV2([programId, config]) // Program accounts (paginationKey)
helius.getTokenAccountsByOwnerV2([owner, filter?, config]) // Token accounts (paginationKey)
helius.getPriorityFeeEstimate({ accountKeys, options }) // Fee estimates
交易
构建和发送优化的交易，具有自动计算单元估算和优先费用。helius.tx.sendSmartTransaction({ instructions, signers }) // Auto-optimized send
helius.tx.createSmartTransaction({ instructions, signers })// Build without sending
helius.tx.sendTransactionWithSender({ ..., region }) // Helius Sender (low latency)
增强交易
将原始交易解析为可读且带标签的格式。helius.enhanced.getTransactions({ transactions }) // Parse by signatures
helius.enhanced.getTransactionsByAddress({ address }) // Parse by address
Webhooks
为链上事件创建和管理实时 HTTP POST 通知。helius.webhooks.create({ webhookURL, transactionTypes, accountAddresses })
helius.webhooks.get(webhookID)
helius.webhooks.getAll()
helius.webhooks.update(webhookID, params)
helius.webhooks.delete(webhookID)
WebSockets
通过 WebSocket 连接流式传输实时区块链数据。helius.ws.logsNotifications(filter, config) // Transaction logs
helius.ws.accountNotifications(address, config) // Account changes
helius.ws.signatureNotifications(signature, config) // Tx confirmation
helius.ws.slotNotifications(config) // Slot updates
helius.ws.programNotifications(programId, config) // Program account changes
helius.ws.close() // Clean up connections
Staking
将SOL委托给Helius验证者并管理委托账户。helius.stake.createStakeTransaction(owner, amountSol) // Stake SOL
helius.stake.createUnstakeTransaction(ownerSigner, stakeAccount) // Unstake
helius.stake.createWithdrawTransaction(withdrawAuth, stakeAcct, dest, lamports)// Withdraw
helius.stake.getHeliusStakeAccounts(wallet) // List stake accounts
Wallet API
通过REST端点查询钱包余额、交易历史、转账和身份信息。helius.wallet.getBalances({ wallet }) // Token balances
helius.wallet.getHistory({ wallet }) // Transaction history
helius.wallet.getTransfers({ wallet }) // Transfer history
helius.wallet.getIdentity({ wallet }) // Known identity lookup
helius.wallet.getBatchIdentity({ addresses }) // Batch identity (max 100)
helius.wallet.getFundedBy({ wallet }) // Funding source
ZK Compression
使用压缩账户和代币以节省98%的链上存储成本。helius.zk.getCompressedAccount({ address }) // Single compressed account
helius.zk.getCompressedAccountsByOwner({ owner }) // By owner
helius.zk.getCompressedTokenAccountsByOwner({ owner }) // Compressed tokens
helius.zk.getCompressedAccountProof({ hash }) // Merkle proof
helius.zk.getCompressedBalance({ address }) // Balance
helius.zk.getValidityProof({ hashes }) // Validity proof
