Summary by CodeRabbit

  • Refactor
    • Unified associated token account creation by consolidating separate instruction variants into a single pathway.
    • Restructured account input requirements, with owner and mint now provided as account inputs rather than instruction data fields.
    • Updated account ordering for improved operational consistency.

✏️ Tip: You can customize this high-level summary in your review settings.

Walkthrough

This pull request consolidates the associated token account (ATA) creation flow by removing the separate ATA2 instruction variant and merging both code paths into a unified implementation. Owner and mint are now sourced from account inputs rather than instruction data, eliminating the CreateAssociatedTokenAccount2 instruction type and related data structures across instruction types, program logic, and SDK APIs.

Changes

Cohort / File(s)Summary
Instruction Data Cleanup
program-libs/ctoken-types/src/instructions/create_associated_token_account.rs, create_associated_token_account2.rs, mod.rs		Removed owner and mint fields from CreateAssociatedTokenAccountInstructionData, eliminated entire CreateAssociatedTokenAccount2InstructionData struct, and removed public module export for create_associated_token_account2
Program Instruction Processing
programs/compressed-token/program/src/create_associated_token_account.rs, create_associated_token_account2.rs, lib.rs		Modified ATA creation to extract owner and mint from account inputs; removed all ATA2 public entry points and instruction variants (CreateAssociatedTokenAccount2, CreateAssociatedTokenAccount2Idempotent); removed discriminators 106 and 107
SDK Consolidation
sdk-libs/compressed-token-sdk/src/ctoken/create_ata.rs		Removed CreateAssociatedTokenAccount2 struct and V2 path; unified CreateAssociatedTokenAccount as single public API; reordered fields to payer, owner, mint, associated_token_account, bump, compressible, idempotent; updated with_compressible parameter naming
Test Updates
sdk-libs/compressed-token-sdk/tests/create_associated_token_account.rs		Updated account count assertion from 5 to 7 to reflect new account layout: owner, mint, payer, ata, system_program, config, rent_sponsor

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

  • Instruction data reshaping: Verify that all downstream code expecting owner and mint in instruction data has been updated to extract from accounts instead
  • SDK API consolidation: Ensure the unified CreateAssociatedTokenAccount struct and reordered fields are correctly used throughout the SDK and don't break existing call sites
  • Account ordering assumptions: Confirm the new account extraction logic (first two accounts = owner, mint) is correctly implemented and documented in all places
  • Discriminator removal: Verify that removing discriminators 106 and 107 doesn't break backward compatibility requirements or affect instruction routing logic

Poem

Two paths converge, yet one must stay—
ATA2 fades, unified's the way.
Owner and mint from accounts we draw,
Simplified instruction, without a flaw. 🏛️

programs/compressed-token/program/src/create_associated_token_account.rs (1)

42-81: LGTM! Clean extraction of owner and mint from accounts.

The refactored process_create_associated_token_account_with_mode properly:

  1. Validates minimum account count before accessing
  2. Splits accounts to extract owner (index 0) and mint (index 1)
  3. Passes remaining_accounts to the inner function, maintaining the expected account order for downstream processing

The detailed account order documentation (lines 50-56) is helpful for maintainability.

sdk-libs/compressed-token-sdk/src/ctoken/create_ata.rs (3)

115-126: LGTM! Account ordering correctly matches program expectations.

The instruction account construction properly orders accounts as:

  1. owner (readonly)
  2. mint (readonly)
  3. payer (signer, mut)
  4. associated_token_account (mut)
  5. system_program (readonly)
    6-7. Optional compressible accounts

This aligns with the program's documented account order (lines 50-56 in create_associated_token_account.rs).

152-175: LGTM!

The invoke method correctly assembles account infos in the same order as the instruction accounts, handling both compressible and non-compressible cases.

203-224: LGTM!

The From implementation correctly converts CreateAssociatedTokenAccountInfos to CreateAssociatedTokenAccount, mapping all fields including the optional compressible configuration.

sdk-libs/compressed-token-sdk/tests/create_associated_token_account.rs (1)

70-82: LGTM! Test correctly validates the unified account structure.

The updated test properly validates 7 accounts for compressible ATA creation:

  • owner, mint, payer, ata, system_program (base 5)
  • config, rent_sponsor (compressible extension 2)

The inline comment documenting the account order is a nice touch for maintainability.

🔇 Additional comments (8)
sdk-libs/compressed-token-sdk/tests/create_associated_token_account.rs (1)

80-81: LGTM!

The comment clearly documents the account order and the assertion correctly validates the expected 7 accounts for the unified compressible ATA creation path.

programs/compressed-token/program/src/create_associated_token_account.rs (3)

22-30: LGTM!

The documentation clearly indicates that owner and mint are now passed as accounts. The inline(always) hint is appropriate for this thin wrapper.

42-81: Clean refactoring with good documentation.

The account order documentation (lines 50-56) is clear and matches the implementation. The validation at lines 62-64 prevents panics from split_at. The delegation pattern to the inner function is well-structured.

192-192: ACTIVE config validation is correctly performed.

The next_config_account function at programs/compressed-token/program/src/create_token_account.rs:128 calls config.validate_active(), which enforces the requirement that token account creation instructions only proceed with ACTIVE config state. The implementation is correct.

sdk-libs/compressed-token-sdk/src/ctoken/create_ata.rs (4)

28-74: LGTM - Clean consolidated structure.

The unified CreateAssociatedTokenAccount struct consolidates the previous V1/V2 paths nicely. The default-compressible behavior (lines 48, 66) is appropriate for a compressed token program. The parameter rename to compressible_params (line 71) improves clarity.

81-133: LGTM!

The instruction builder correctly:

  1. Constructs instruction data with only bump and compressible_config (owner/mint removed per refactor).
  2. Selects the appropriate discriminator (100 for regular, 102 for idempotent).
  3. Orders accounts as: owner, mint, payer, ata, system_program, [optional: config, rent_sponsor].

This aligns with the program's expected account order documented in create_associated_token_account.rs.

136-201: LGTM!

The CreateAssociatedTokenAccountInfos struct and its invoke/invoke_signed methods correctly handle both compressible (7 accounts) and non-compressible (5 accounts) cases. The account ordering in the invoke arrays matches the instruction builder.

203-225: LGTM!

The From implementation correctly converts account infos to the builder struct. Setting compress_to_account_pubkey: None (line 219) is correct for ATAs, matching the program's validation that rejects ATAs with custom compression targets.
