Function: transferOwnership()

transferOwnership(chain, newOwner, seClient, _verifyBlindSig?, _chainProvider?): Promise<StateChain>

Transfer ownership of a statechain UTXO to a new owner.

Public API: transferOwnership(chain, newOwner, seClient)

Creates an on-chain state-update TX: input: current MULTISIG coin with STATE(0) = oldOwnerPkd output: same locking address with STATE(0) = newOwnerPkd

Signing flow:

  • chain.currentOwner.sign(txDigest) — old owner signs TX body digest.
  • seClient.blindSign(hex(txDigest)) — SE countersigns same digest. Both satisfy MULTISIG(2 STATE(0) SE) for the input coin.

Post-transfer:

  • New owner's reclaim TX is built via newOwner.sign(reclaimDigest). chain.reclaimTx always reflects CURRENT owner — never initial owner.
  • Old owner's transferKeySeed is moved to TransferRecord.transferKey then zeroed in-place on the original owner object so the secret does not persist in hot state after the ownership hop.

Parameters​

chain​

StateChain

Active statechain (must have currentOwner.sign).

newOwner​

StatechainOwner

Recipient identity + signing capability.

seClient​

SEClient

SE client for countersigning the state-update TX.

_verifyBlindSig?​

(sig, commitment, sePkdHex) => boolean

Optional SE blind-sig verification override (test use). Defaults to wotsVerifyDigest. Production callers should omit this.

_chainProvider?​

ChainStateProvider

Optional: broadcast the state-update TX on-chain.

Returns​

Promise<StateChain>
