computeAuthWitMessageHash

Type: Constant

Compute an authentication witness message hash from an intent and metadata If using the IntentInnerHash, the consumer is the address that can "consume" the authwit, for token approvals it is the token contract itself. The innerHash itself will be the message that a contract is allowed to execute. At the point of "approval checking", the validating contract (account for private and registry for public) will be computing the message hash (H(consumer, chainid, version, inner_hash)) where the all but the inner_hash is injected from the context (consumer = msg_sender), and use it for the authentication check. Therefore, any allowed innerHash will therefore also have information around where it can be spent (version, chainId) and who can spend it (consumer). If using the CallIntent, the caller is the address that is making the call, for a token approval from Alice to Bob, this would be Bob. The action is then used along with the caller to compute the innerHash and the consumer.

Value Type: any

getMessageHashFromIntent

Wallet

`wallet/account_entrypoint_meta_payment_method.ts`

AccountEntrypointMetaPaymentMethod

Type: Class

Fee payment method that allows an account contract to pay for its own deployment It works by rerouting the provided fee payment method through the account's entrypoint, which sets itself as fee payer. If no payment method is provided, it is assumed the account will pay with its own fee juice balance. Usually, in order to pay fees it is necessary to obtain an ExecutionPayload that encodes the necessary information that is sent to the user's account entrypoint, that has plumbing to handle it. If there's no account contract yet (it's being deployed) a MultiCallContract is used, which doesn't have a concept of fees or how to handle this payload. HOWEVER, the account contract's entrypoint does, so this method reshapes that fee payload into a call to the account contract entrypoint being deployed with the original fee payload. This class can be seen in action in DeployAccountMethod.ts#getSelfPaymentMethod

Implements: FeePaymentMethod
