deposit_for_burn

Burns vault USDC through CCTP for an outbound cross-chain transfer.

Handler narrative

Load the GLAM state or program account required by the instruction and verify the signer.
Verify that the integration is enabled on the vault and that the caller has the required delegate permission or owner authority.
Validate the instruction-specific policy, then invoke the external protocol with the vault authority where required.

The submitted accounts must match the declared account list, signer requirements, writable requirements, fixed program addresses, and account relationships shown below.
The GLAM state account is the source of truth for owner, enabled integrations, delegate permissions, policies, assets, borrowable assets, timelock settings, mint linkage, and pricing records.
The vault account must be the PDA controlled by the core protocol program and derived conceptually from the state account; instructions use it as the vault authority for SOL, token accounts, and external positions.
The vault integration ACL must enable this integration before the instruction is accepted; that enablement is defined on the GLAM state account.
If the signer is not the owner, the delegate ACL on the GLAM state must contain the exact protocol permission required by this instruction; registering a delegate alone is insufficient.
Instruction-specific destination accounts must satisfy the external protocol's own account model; GLAM validates the accounts it needs for authorization and policy enforcement, then passes the remaining protocol accounts through CPI.
Asset, amount, and destination restrictions must satisfy the configured transfer or destination policy when that policy is present.

Uses the standard Big Seven account pattern, plus the instruction-specific accounts below.

Account	Role	Description
sender_authority_pda	read-only	Instruction-specific account supplied by the caller or SDK.
burn_token_account	writable	Token account read or written by the instruction.

message_transmitter	writable	Instruction-specific account supplied by the caller or SDK.
token_messenger	read-only	Instruction-specific account supplied by the caller or SDK.
remote_token_messenger	read-only	Instruction-specific account supplied by the caller or SDK.
token_minter	read-only	Token mint account used by the instruction.
local_token	writable	Instruction-specific account supplied by the caller or SDK.
burn_token_mint	writable	Token mint account used by the instruction.
message_sent_event_data	signer, writable	Token account read or written by the instruction.
message_transmitter_program	read-only	Fixed program or sysvar account required by this instruction.
token_messenger_minter_program	read-only	Token mint account used by the instruction.
event_authority	read-only	Instruction-specific account supplied by the caller or SDK.

Argument	Type	Notes
args	DepositForBurnParams	Instruction parameter object; field details are listed below. Fields: `amount: u64`; `destination_domain: u32`; `mint_recipient: pubkey`; `destination_caller: pubkey`; `max_fee: u64`; `min_finality_threshold: u32`

Enable CCTP on the vault integration ACL. Protocol bitflag: 0b00000001.
Delegate permission: CCTP Transfer (0b0000000000000001).
Destination and asset restrictions must satisfy the configured transfer or destination policy when one is set.

No additional cross-instruction constraint is documented beyond account initialization, authority checks, and policy validation.
