# Save the block list address
BLOCK_LIST=5HnJkLmNoPqRsTuVwXyZ987654321defghijk

# ============================================================================
# STEP 5: Apply Lists to Mint
# ============================================================================

# Configure the block list to be used for this mint's permissionless operations
allow-block-list apply-lists-to-mint $MINT $BLOCK_LIST

# ============================================================================
# STEP 6: Enable Permissionless Thaw
# ============================================================================

# Allow users to thaw their own accounts (if not on block list)
# --enable-thaw: Users can self-service unfreeze after passing gate checks
# --disable-freeze: Only authority can freeze
token-acl set-instructions --enable-thaw --disable-freeze $MINT

# ============================================================================
# STEP 7: Manage Block List (Compliance Operations)
# ============================================================================

# To fully block a user, you need TWO steps:
# 1. Add to block list (prevents future thawing)
# 2. Freeze their token account (stops current usage)

# Step 7a: Add wallet to block list
# Replace with actual wallet address to block (must be valid base58 pubkey)
allow-block-list add-wallet $BLOCK_LIST <WALLET_TO_BLOCK>

# Step 7b: Freeze their existing token account (if they have one)
# This requires the token account address, not the wallet address
# spl-token address --verbose --token $MINT to get the token account address
# token-acl freeze <TOKEN_ACCOUNT_ADDRESS>

# Note: Adding to block list alone only prevents them from THAWING.
# If their account is already thawed, they can still use it until you freeze it!

# Later, if sanctions are lifted:
# 1. Remove from block list
# allow-block-list remove-wallet $BLOCK_LIST <WALLET_ADDRESS>
# 2. User can then thaw their account again

# ============================================================================
# STEP 8: User Creates Account and Thaws
# ============================================================================

# A user can now create their token account and thaw it in one command
# Use your own wallet or generate one: solana-keygen new --no-outfile
USER_WALLET=$(solana address)  # Uses your configured wallet
token-acl create-ata-and-thaw-permissionless --mint $MINT --owner $USER_WALLET

# Output:
# ✅ Created ATA: 8AbCdEfGhIjKlMnOpQrStUvWxYz123456789xyz
# ✅ Thawed successfully!

# ============================================================================
# STEP 9: Mint Tokens to User
# ============================================================================

# Now the issuer can mint tokens to the user's thawed account
spl-token mint $MINT 1000 --recipient-owner $USER_WALLET

# Verify balance
spl-token balance $MINT
