sigil_getAccountNonce

Method

sigil_getAccountNonce is registered in the canonical JSON-RPC catalog. Use POST /rpc, Content-Type: application/json, JSON-RPC 2.0 and a caller-controlled request id. Node RPC profile, build feature and runtime activation checks still apply.

Get the next nonce for an account (replay protection).

Request binding

Source handler: rpc_server::handle_get_account_nonce in sigil/node/sigil-node/src/rpc_server.rs, line 3183.

The handler directly reads these named fields: did. Additional typed parsing, aliases and nested validation are defined by its request types. Field presence alone does not establish optionality.

Parsing excerpt

These source excerpts show binding and validation; they are not runnable client code.

        .or_else(|| req.params.get("did").and_then(|v| v.as_str()));

Read example

Responses and failures

Check HTTP status, parse the JSON-RPC envelope, reject error, and require result on success. Preserve large base-unit integers without floating-point rounding. A catalog method does not bypass authentication, capability, policy or activation requirements.
