Polygon method guide

Last updated:

eth_getTransactionCount returns the nonce of an account: the total number of transactions that address has sent, counted up to and including the block you specify. The value comes back as a hex-encoded quantity (e.g. "0x2a" = 42).

The nonce is the primary input for transaction signing. Every transaction an account sends must carry a strictly increasing nonce; using the count returned for the "pending" block tag gives you the next nonce to assign to a new transaction.

High-throughput callers: if you are sending many transactions in quick succession (e.g. a bot), do not fetch the nonce per transaction. The RPC view lags behind transactions you have already broadcast but that are not yet mined, so you will reuse a nonce and get rejected — and you will burn your RPS budget. Fetch the "pending" count once at startup, then track and increment the nonce locally, reconciling against the RPC only on error.

Examples

curl https://triport.io/polygon \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_getTransactionCount","params":[]}'
const res = await fetch("https://triport.io/polygon", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
  "jsonrpc": "2.0",
  "id": 1,
  "method": "eth_getTransactionCount",
  "params": []
}),
});
const data = await res.json();
import requests
resp = requests.post(
    "https://triport.io/polygon",
    headers={"Authorization": "Bearer <api-key>"},
    json={"jsonrpc":"2.0","id":1,"method":"eth_getTransactionCount","params":[]},
)
print(resp.json())
