Example

import { getDepositInstructionAsync } from "../private-channel-escrow-program/clients/typescript/src/generated";

// allowedMint and instanceAta are auto-derived from mint and instance
const depositIx = await getDepositInstructionAsync({
  payer: payerSigner,
  user: userSigner,
  instance: instancePda,
  mint: mintAddress,
  userAta: userAtaAddress,
  amount: 1_000_000n,
  recipient: null
});

Important Notes

Program ID: 9tgHa1DcnaSSUtmMsst8ovKTe1Gfxzezn27KnH9xXYeU
For Token-2022 mints, pass tokenProgram: TOKEN_2022_PROGRAM_ADDRESS explicitly, since it defaults to the standard SPL Token Program
The allowed_mint PDA must exist (created by AllowMint); depositing an unlisted mint throws InvalidAllowedMint
When recipient is None, the depositing user's channel balance is credited; when provided, the specified wallet's balance is credited instead
Both payer and user must sign the transaction
The instance_ata must already exist (created by AllowMint for this mint)
