Build Starknet Apps with starknet.js
Starknet integrations require precise provider, account, transaction, and fee handling across several APIs. This skill provides focused starknet.js v9.x patterns for reliable TypeScript applications.
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "starknet-js" from https://skillstore.io/skills/internet-court-starknet-js.md and its manifest at https://skillstore.io/api/skills/internet-court-starknet-js/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.
Use these links when an AI agent, crawler, or script needs clean context instead of reading the full page.
Using "starknet-js". Connect to Starknet Sepolia and read an ERC-20 balance.
Expected outcome:
A concise TypeScript integration plan covering the RPC provider, contract ABI, token address, account address, and BigInt balance handling.
Using "starknet-js". Prepare an approve and transfer transaction with fee controls.
Expected outcome:
Using "starknet-js". Assess a sponsored paymaster transaction.
Expected outcome:
A risk-focused review of network selection, supported gas tokens, sponsorship policy, signer authority, and user confirmation requirements.
All 99 static findings are false positives after contextual review. The matches describe documentation syntax, public RPC examples, relative references, standard configuration access, or intentional environment-based key loading; no command execution, exfiltration, or prompt injection was identified.

Create a TypeScript starter that reads contract state and submits a controlled transaction through starknet.js.
Design wallet connection, sponsored execution, and alternative gas-token flows with clear fee and network checks.
Compare account, multicall, simulation, nonce, and fee patterns before integrating them into an existing Starknet service.
Show me how to connect to Starknet Sepolia with starknet.js v9.x and read a contract balance. Explain each required input.
Create a TypeScript pattern for a typed starknet.js contract call. Include ABI expectations, address validation, and readable error handling.
Design a starknet.js v9.x flow for approve plus transfer using multicall. Include simulation, nonce handling, fee estimation, and confirmation checks.
Review this Starknet paymaster design for network, fee, signer, replay, and failure handling. Recommend a production-ready sequence and explicit approval gates.
