Validate and broadcast an already-signed Bitcoin transaction. Disabled unless ALLOW_BITCOIN_BROADCAST=true; never signs or stores keys.

Decode a serialized Bitcoin transaction without broadcasting it.

Estimate a Bitcoin fee rate for confirmation within a target number of blocks.

Scan the Bitcoin UTXO set for an address and return its confirmed spendable outputs. This is not address history and shared RPC nodes may reject concurrent scans.

Read a Bitcoin block by height or hash with selectable verbosity.

Return Bitcoin network, chain height, sync, and pruning information.

Read a raw Bitcoin transaction by txid. A block hash can make confirmed transaction lookup more reliable.

Read an unspent Bitcoin transaction output. Returns null when the output is spent or unknown.

Preflight and broadcast an already-signed EVM transaction. Disabled unless ALLOW_EVM_BROADCAST=true; never signs or stores keys.

Run a read-only eth_call with pre-encoded calldata. This never submits a transaction.

Estimate gas for an unsigned EVM transaction. Values are accepted as decimal or hex quantities.

Read an EVM block by number, tag, or block hash.

Return the latest EVM block number from the configured endpoint.

Return the EVM chain ID and upstream client version.

Read EVM event logs using an address/topics filter and bounded block range.

Read an address native-token balance at an EVM block without requiring a wallet.

Read an EVM transaction and its receipt by transaction hash.

Encode, execute, and decode a read-only smart-contract function using a supplied JSON ABI.
