DEVREL-930 Oapp solana migrate lzrt v2 #1850

nazreen · 2025-11-28T13:25:00Z

Changes

update the Solana OApp program to use LzReceiveTypesV2
Add a debug.ts script for EVM (tasks/evm/debug.ts)
updated README.md to mention how to read strings for both Solana and EVM
update the Kinobi renderer to explicitly declare formatting (before this, every gen:api run would result in a diff, even if the program code hasn't changed)

Needs internal review but should not be merged yet.

looks good

please make sure to test on testnet as well to see if automatic delivery is working

one small thing, seems event authority is unused, please fix

PR Summary

Migrate Solana OApp to V2 execution planning

Replace legacy lz_receive_types with lz_receive_types_info (version probe) and lz_receive_types_v2 (returns execution plan) in the program and client
Expand Store/LzReceiveTypesAccounts (add alt, bump) and accept optional alt in init_store; derive lzReceiveTypesAccounts PDA in client pda.ts
Update lz_receive to include payer and wire Endpoint clear via remaining accounts

Generated SDK and types refresh

Regenerate client with new instructions (lzReceiveTypesInfo, lzReceiveTypesV2) and new types (AddressLocator, AccountMetaRef, Instruction, LzReceiveTypesV2Result); remove V1 types
Clear hardcoded program IDs; minor serializer/size/layout adjustments; add Kinobi renderer formatting to stabilize output

Tooling and docs

Add Hardhat task lz:oapp:evm:debug to read EVM contract data() and extend Solana oappCreate to accept --alt
README: add section on viewing stored strings for Solana and EVM
layerzero.config tweaks (comments, confirmations)

examples/oapp-solana/lib/client/generated/my_oapp/instructions/lzReceive.ts

-export type LzReceiveInstructionData = {
-    discriminator: Uint8Array
-    params: LzReceiveParams
-}


TypeScript client missing payer account for lzReceive instruction

High Severity

The Rust LzReceive struct was updated to include a new payer: Signer<'info> account at index 0, shifting store to index 1 and peer to index 2. However, the auto-generated TypeScript client for lzReceive was not updated accordingly — it still only has store at index 0 and peer at index 1, completely missing the payer account. While the Executor uses lz_receive_types_v2 to get the correct account list (which does include payer via AddressLocator::Payer), any direct usage of the TypeScript lzReceive function would fail because the account order doesn't match what the program expects.
