transferChecked is called automatically under the hood by transferInterface and createTransferInterfaceInstructions. You do not need to call it directly.

---description: Add transfer-checked CPI to an Anchor programallowed-tools: Bash, Read, Write, Edit, Glob, Grep, WebFetch, AskUserQuestion, Task, TaskCreate, TaskGet, TaskList, TaskUpdate, TaskOutput, mcp__deepwiki, mcp__zkcompression---## Add transfer-checked CPI to an Anchor programContext:- Guide: https://zkcompression.com/light-token/cookbook/transfer-checked- Skills and resources index: https://zkcompression.com/skill.md- SPL to Light reference: https://zkcompression.com/api-reference/solana-to-light-comparison- Crate: light-token (TransferCheckedCpi)- Example: https://github.com/Lightprotocol/examples-light-token/tree/main/programs/anchor/basic-instructions/transfer-checkedKey CPI struct: `light_token::instruction::TransferCheckedCpi`Note: TransferInterface uses TransferChecked under the hood for Light-to-Light transfers.Use TransferChecked/TransferCheckedCpi directly only when you need Light-to-Light without interface routing.### 1. Index project- Grep `declare_id|#\[program\]|anchor_lang|Account<|Pubkey|invoke|transfer|decimals|amount` across src/- Glob `**/*.rs` and `**/Cargo.toml` for project structure- Identify: program ID, existing instructions, account structs, token accounts- Read Cargo.toml — note existing dependencies and framework version- Task subagent (Grep/Read/WebFetch) if project has multiple crates to scan in parallel### 2. Read references- WebFetch the guide above — review the Program tab CPI code samples- WebFetch skill.md — check for a dedicated skill and resources matching this task- TaskCreate one todo per phase below to track progress### 3. Clarify intention- AskUserQuestion: what is the goal? (add transfer-checked to existing program, new program from scratch, migrate from SPL transfer_checked)- AskUserQuestion: should the authority be an external signer or a PDA? (determines invoke vs invoke_signed)- Summarize findings and wait for user confirmation before implementing### 4. Create plan- Based on steps 1–3, draft an implementation plan: which files to modify, what code to add, dependency changes- Follow the guide's step order: Build TransferCheckedCpi struct → call .invoke() or .invoke_signed()- If anything is unclear or ambiguous, loop back to step 3 (AskUserQuestion)- Present the plan to the user for approval before proceeding### 5. Implement- Add deps if missing: Bash `cargo add light-token anchor-lang@0.31`- Follow the guide and the approved plan- Write/Edit to create or modify files- TaskUpdate to mark each step done### 6. Verify- Bash `anchor build`- Bash `anchor test` if tests exist- TaskUpdate to mark complete### Tools- mcp__zkcompression__SearchLightProtocol("<query>") for API details- mcp__deepwiki__ask_question("Lightprotocol/light-protocol", "<q>") for architecture- Task subagent with Grep/Read/WebFetch for parallel lookups- TaskList to check remaining work
