Expand description

Compute the Neo N3 contract hash for a deployment transaction.

Neo derives the deployed contract hash from:

  • the deploy transaction sender (UInt160)
  • the NEF checksum (u32)
  • the manifest name (string)

This matches Neo.SmartContract.Helper.GetContractHash(sender, nefChecksum, name) in the Neo node implementation:

  • ScriptBuilder emits: ABORT, PUSH sender, PUSH nefChecksum, PUSH name
  • Contract hash is Hash160(script) (RIPEMD160(SHA256(script))) interpreted as UInt160.

Inputs and outputs use the VM byte order for UInt160 (little-endian 20 bytes).
