rotateasset "icu_txid" icu_vout "icu_address" "asset_id" {"vk_data":"hex","max_root_age":n,"tfr_flags":n,"unlock_fee_bump":amount,"icu_payload":"hex","icu_ctxt_commit":"hex","icu_plain_commit":"hex","icu_visibility":n,"policy_quorum_bps":n,"issuance_cap_units":n,"issuance_cap":"str","icu_compressed":bool,"autofund":bool,"broadcast":bool,"fee_rate":n} Unified convenience wrapper for asset parameter rotation. Automatically detects whether ZK or ICU rotation is needed and routes accordingly. Cannot mix ZK and ICU changes in a single call. 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, required) Rotation parameters { "vk_data": "hex", (string, optional) New ZK verification key data "max_root_age": n, (numeric, optional) Maximum merkle root age "tfr_flags": n, (numeric, optional) Transfer flags "unlock_fee_bump": amount, (numeric or string, optional) BTC to add (min 0.5 for ICU) "icu_payload": "hex", (string, optional) New ICU payload "icu_ctxt_commit": "hex", (string, optional) Ciphertext commitment "icu_plain_commit": "hex", (string, optional) Plaintext commitment "icu_visibility": n, (numeric, optional) ICU visibility "policy_quorum_bps": n, (numeric, optional) Quorum basis points "issuance_cap_units": n, (numeric, optional) Issuance cap in base units "issuance_cap": "str", (string, optional) Issuance cap expressed in asset units (e.g., "50.0"). Overrides issuance_cap_units. "icu_compressed": bool, (boolean, optional) Use zstd compression "autofund": bool, (boolean, optional, default=true) Auto-fund fees "broadcast": bool, (boolean, optional, default=false) Broadcast transaction "fee_rate": n, (numeric, optional) Fee rate in sat/vB } Result: "hex" (string) Transaction ID if broadcast, otherwise hex Examples: > bitcoin-cli rotateasset "icu_txid" 0 "bc1q..."

Signature

rotateasset(icu_txid: string, icu_vout: number, icu_address: string, asset_id: string, options: object) → any
