Generate txSkeleton for writing binary data to CKB via Type ID, usually for deploying contracts.
Deploying via Type ID makes it possible to upgrade contract, for more information about Type ID, please check: https://xuejie.space/2020_02_03_introduction_to_ckb_script_programming_type_id/

@ckb-lumos/common-scriptsCommon script implementation for lumos. Includes
secp256k1_blake2block script,secp256k1_blake160_multisiglock script,daotype script,sudttype script now.LocktimePoolscript includessecp256k1_blake160_multisigcells which with locktime in lockargs(whichargstotal length is 28 bytes, last 8 bytes is asinceformat locktime in BigUInt64LE encode) andDAOstep2 cells.commonscript allows you totransfercapacity fromfromInfosto an address. It will use locktime pool cells first by default.deployscript providesgenerateDeployWithDataTx,generateDeployWithTypeIdTxandgenerateUpgradeTypeIdDataTx, these generators help in the process of deploying contracts.p2pkhscripts generates message for signing P2PKH transaction.Usage
