+### `evm_setAccountNonce`
+
+[source](src/node/evm.rs)
+
+Modifies an account's nonce by overwriting it.
+The new nonce must be greater than the existing nonce.
+
+#### Arguments
+
++ `address: Address` - The `Address` whose nonce is to be changed
++ `nonce: U256` - The new nonce
+
+#### Example
+
+```bash
+curl --request POST \
+  --url http://localhost:8011/ \
+  --header 'content-type: application/json' \
+  --data '{
+    "jsonrpc": "2.0",
