Required conditions

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.
The instruction metadata names DepositCollateral as the delegate permission for this instruction.
deposit_mint must be present in the Loopscale deposit allowlist.

Policy & permissions

Enable the Loopscale integration program on the vault integration ACL before Loopscale position actions.
Delegate permission: DepositCollateral.

TypeScript SDK usage

const depositCollateralIx =
  await glamClient.loopscale.txBuilder.depositCollateralIx(
    { amount, assetType: 0, assetIdentifier, assetIndexGuidance },
    { loan, depositMint: collateralMint },
  );

Cross-instruction constraints

The Loopscale loan must exist; locking and unlocking determine when principal and collateral movements are valid.
