Functions

addApproveArbitrator

▸ addApproveArbitrator(escrowId, callbacks?): Promise<any>

Opens a modal that checks whether there's an arbitrator proposed or defined for this escrow. If there is no arbitrator proposed or defined, it will display a form for the user to submit their proposed arbitrator's address and fee. If an arbitrator has been proposed, it displays the proposal and allows to either approve it (if it was the other party who proposed the arbitrator) or to change the proposal (if this user sent the original proposal)

Parameters

Name	Type	Description
escrowId	number	ID of the escrow
callbacks?	IArbitrationTransactionCallbacks	Because the developer doesn't know what the user's proposal is, they can get the information about what user sent from the broadcasted event, and how the contract processed the proposal in the confirmed event

Returns

Promise<any>

Defined in

ui/render/addApproveArbitrator.ts:20

Parameters

Name	Type	Description
escrowIds	number[]	List of escrow IDs to be claimed. You can get this from indexer's getClaimableEscrows() function

pay

▸ pay(paymentProps, callbacks?): Promise<any>

Opens a payment modal, which summarizes the escrow parameters for the user (buyer) and displays a button to Pay. If the user is on an incorrect network, it asks them to switch (and provides network configuration automatically).

Ultimately it calls ui.pay() function, which connects user's wallet, checks for the balance in the selected token, asks for approval, and if the address was provided in ENS format, resolves that to ETH address.

Example

// The most simple example of 1 ETH payment with 2 week challenge period and with no arbitrator or a marketplace
