Ethereum JSON-RPC
The Ethereum JSON-RPC surface on
POST https://triport.io/eth— the standardeth_*set plusdebug_,trace_,txpool_,net_andweb3_namespaces, with node-admin namespaces explicitly documented as not supported.

How to call
Every method takes the same envelope — only method and params change:
curl https://triport.io/eth \
-H "x-token: $TRIPORT_API_KEY" \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"eth_getBalance",
"params":["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045","latest"]}'Batching (a JSON array of request objects) is supported; each entry is tier-checked and rate-limited individually.
Support semantics
| Status | Meaning |
|---|---|
| Supported | Routed to an upstream node, result returned unchanged (eth_*, debug_*, trace_*, txpool_*, net_*, web3_*). |
| Extension | Provider-specific additions that are not base chain RPC (e.g. bundle submission). |
| Not supported | Node-admin namespaces (admin_*, personal_*) return -32601 (method_unknown) by design; their pages document that behavior so the response is never a surprise. |
See Errors for the full error envelope.
Method reference
The pages below are grouped by namespace — eth_, debug_, trace_,
txpool_, net_, web3_, and the documented-unsupported admin_/personal_
set. Subscriptions (newHeads, logs, newPendingTransactions, syncing)
live on the WebSocket channel — see Ethereum WS.
eth_* 29

POST eth_getLogs
Returns the array of event logs matching a filter — by block range or block hash, contract address, and indexed topics.
POST eth_getProof
Returns the Merkle-Patricia proof for an account and, optionally, a set of its storage slots at a given block, per EIP-1186.
POST eth_getStorageAt

POST eth_getTransactionCount
Returns the number of transactions sent from an address — its nonce — at a given block.
POST eth_getTransactionReceipt
Returns the receipt of a transaction by its hash — including execution status, gas used, emitted logs, and (for contract deployments) the new contract address.
POST eth_getUncleByBlockHashAndIndex
Returns the uncle (ommer) block at a given index within a block addressed by its 32-byte hash, or null if there is no uncle at that position.

POST eth_sendRawTransaction
Broadcasts a signed, RLP-encoded transaction to the Ethereum network and returns its transaction hash.
POST eth_syncing
Reports whether the Ethereum node is currently syncing, returning false when fully synced or a sync-progress object while catching up.
debug_* 7
POST debug_getRawBlock
Returns the RLP-encoded bytes of an entire Ethereum block, identified by block number or block hash.
POST debug_getRawHeader
Returns the RLP-encoded bytes of a block header, as a single hex string.
POST debug_storageRangeAt
Returns a page of contract storage slots as they existed at a specific transaction within a given block.
POST debug_traceBlockByHash
Replays every transaction in a block (identified by its hash) through the EVM and returns a trace for each one.
POST debug_traceBlockByNumber
Replays every transaction in a block identified by number or tag and returns the EVM execution trace for each one.
POST debug_traceCall
Executes an eth_call against the state of a chosen block and returns the full EVM execution trace, without broadcasting a transaction.
POST debug_traceTransaction
Replays a single already-mined transaction and returns its full EVM execution trace.
trace_* 5
POST trace_block
Returns OpenEthereum-style action traces for every transaction in a single Ethereum block.
POST trace_call
Executes a transaction call against the state of a chosen block and returns the requested Parity-style traces (trace, vmTrace, stateDiff) without broadcasting anything.
POST trace_filter
Returns all transaction traces (call frames) across a range of blocks that match an optional sender/recipient filter, with cursor-style pagination.
POST trace_replayBlockTransactions
Re-executes every transaction in a block and returns a full execution trace — call graph, optional VM-level steps, and state changes — for each one.
POST trace_transaction

net_* 3
POST net_listening
Returns whether the Ethereum node is actively listening for network connections.
POST net_peerCount
