Notary Contract

Back to Native Contracts

The Notary native contract models Neo N3 notary deposits and notary-assisted transaction helpers. The embedded runtime implements a deterministic in-memory subset for compiler/runtime tests; it does not model the full network notary service.

Methods

Method	Devpack wrapper	Return	Safe	Embedded runtime behavior
verify	NativeCalls.notaryVerify(signature)	bool	✅	Returns true.
balanceOf	NativeCalls.notaryBalanceOf(account)	uint256	✅	Reads the embedded deposit amount for the account, or zero.
expirationOf	NativeCalls.notaryExpirationOf(account)	uint256	✅	Reads the embedded deposit expiration height, or zero.
lockDepositUntil	NativeCalls.notaryLockDepositUntil(account,till)	bool	❌	Extends an existing embedded deposit when till is greater.
withdraw	NativeCalls.notaryWithdraw(from,to)	bool	❌	Removes an embedded deposit for from; to is not modeled.
getMaxNotValidBeforeDelta	NativeCalls.notaryGetMaxNotValidBeforeDelta()	uint256	✅	Returns the embedded max-not-valid-before delta value.
setMaxNotValidBeforeDelta	NativeCalls.notarySetMaxNotValidBeforeDelta(value)	void	❌	Updates the embedded max-not-valid-before delta value.
onNEP17Payment	NativeCalls.notaryOnNEP17Payment(from,amount,data)	void	❌	Records an embedded deposit and optional expiration value.

Embedded Runtime Limits

Authorization, real transaction-notary coordination, and network service behavior are not modeled. Use Neo-Express or TestNet for flows that depend on production notary consensus semantics.
