Crate orml_payments

This pallet allows users to create secure reversible payments that keep funds locked in a merchant’s account until the off-chain goods are confirmed to be received. Each payment gets assigned its own judge that can help resolve any disputes between the two parties.

Terminology

• Created: A payment has been created and the amount arrived to its destination but it’s locked.
• NeedsReview: The payment has bee disputed and is awaiting settlement by a judge.
• IncentivePercentage: A small share of the payment amount is held in escrow until a payment is completed/cancelled. The Incentive Percentage represents this value.
• Resolver Account: A resolver account is assigned to every payment created, this account has the privilege to cancel/release a payment that has been disputed.
• Remark: The pallet allows to create payments by optionally providing some extra(limited) amount of bytes, this is referred to as Remark. This can be used by a marketplace to separate/tag payments.
• CancelBufferBlockLength: This is the time window where the recipient can dispute a cancellation request from the payment creator.

Types

The PaymentDetail struct stores information about the payment/escrow. A “payment” in virto network is similar to an escrow, it is used to guarantee proof of funds and can be released once an agreed upon condition has reached between the payment creator and recipient. The payment lifecycle is tracked using the state field. The PaymentState enum tracks the possible states that a payment can be in. When a payment is ‘completed’ or ‘cancelled’ it is removed from storage and hence not tracked by a state.
