What is starknet-anonymous-wallet?

A guide for creating and using privacy-focused Starknet wallets through Typhoon, then reading from or sending transactions to Starknet smart contracts.

Use it to create or load a Typhoon account, inspect contract interfaces, simulate transactions, check token allowances, or call contracts.

It provides a wallet workflow for agents that need to interact with Starknet while keeping the wallet context anonymous.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.02392
Opus 5.5	$0.00013	$0.00957
Sonnet 5.5	$0.00006	$0.00478
Haiku 4.5	$0.00003	$0.00239

Security

Grade A, and why

starknet-anonymous-wallet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 24d ago.

The scan reads SKILL.md. This mod also ships 15 executable files (scripts/_keys.js, scripts/_network.js, scripts/_rpc.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.

typhoon-starknet-account

This skill provides agent-facing scripts for:

Creating/loading a Starknet account (Typhoon flow)
Discovering ABI / functions
Reading & writing to contracts
Preflight (simulate + fee estimate)
Allowance checks with human amounts

When to Use

Creating or operating privacy-focused Starknet accounts through the Typhoon flow.
Running agent-side contract reads, writes, preflight simulation, or allowance checks from an anonymous wallet context.

When NOT to Use

Standard non-private wallet management, DeFi routing, or payment-link flows.
Cairo contract authoring, deployment operations, or security audits.

Quick Start

Deep dives: references/ (ABI discovery, Typhoon account flow, preflight/fee simulation notes)
Adjacent modules: skills catalog
Account flow examples: scripts/create-account.js, scripts/parse-smart.js, scripts/resolve-smart.js
Read/write examples: scripts/read-smart.js, scripts/invoke-contract.js, scripts/avnu-swap.js
Allowance checks example: scripts/read-smart.js (call ERC20 allowance(owner, spender))

Prerequisites

npm install starknet@^10.8.0 typhoon-sdk@^1.1.13 @andersmyrmel/vard@^1.2.0 @avnu/avnu-sdk@^4.2.0 compromise@^14.14.5 ws@^8.19.0

starknet.js 10 requires Node.js 22+.

RPC setup (required for onchain reads/writes)

These scripts talk to Starknet via JSON-RPC. Configure one of:

Set STARKNET_RPC_URL in your environment (recommended), OR
Pass rpcUrl in the JSON input for scripts that support it.

If neither is provided, scripts fall back to Cartridge's keyless public mainnet RPC (spec 0.10, rate limited):

https://api.cartridge.gg/x/starknet/mainnet/rpc/v0_10

This endpoint has no WebSocket support, so watch-events-smart.js falls back to HTTP polling unless you pass a wsRpcUrl from your own provider.

Swap gas (AVNU paymaster)

scripts/avnu-swap.js executes swaps through the AVNU paymaster in default fee mode: gas is paid in an ERC-20 rather than from the account's STRK balance. No paymaster API key is needed; sponsored (dApp-paid) mode is not used.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
