rotatezk "icu_txid" icu_vout "icu_address" "asset_id" ( {"vk_data":"hex","compliance_root":"hex","max_root_age":n,"tfr_flags":n,"autofund":bool,"broadcast":bool,"fee_rate":n} ) Rotate ZK verification parameters for an asset (mutable, no unlock fee bump required). Updates max_root_age, zk_vk_commitment, tfr_flags without governance overhead. Requires spending the current ICU (issuer) output. Arguments: 1. icu_txid (string, required) Current ICU transaction ID 2. icu_vout (numeric, required) Current ICU output index 3. icu_address (string, required) New ICU destination address 4. asset_id (string, required) Asset ID to rotate 5. options (json object, optional) ZK rotation options { "vk_data": "hex", (string, optional) New ZK verification key data (will be chunked and committed) "compliance_root": "hex", (string, optional) New compliance Merkle root commitment (32-byte hex) "max_root_age": n, (numeric, optional) Maximum merkle root age in blocks "tfr_flags": n, (numeric, optional) Transfer validation flags "autofund": bool, (boolean, optional, default=true) Automatically fund transaction fees "broadcast": bool, (boolean, optional, default=false) Broadcast after signing "fee_rate": n, (numeric, optional) Fee rate in sat/vB } Result: "hex" (string) Transaction ID if broadcast, otherwise hex Examples: > bitcoin-cli rotatezk "icu_txid" 0 "bc1q..."
