Encrypted metadata

KYC payments contain two important pieces of encrypted metadata: the signer information, and the Fulfillment data needed to release the escrow. These are embedded into a MemoTag.

The KYC payment starts as an escrow by submitting an escrowCreate transaction. The escrow will be a Timed conditional with expiration (opens in a new tab), which means that:

• ✅ The buyer can release the payment immediately and within 1-15 days.
• ℹ️ The seller can callback the escrow after an unreleased payment from 15-30 days.
• ❗️ The buyer can cancel the payment from 30 days onwards.

To ensure these times are respected, the escrowCreate uses a Condition field which relies on a Fulfillment unknown to the seller. The Fulfillment is stored in two formats:

1. Accessible to the seller time-locked for 30 days, and encrypted with its public key.
2. Accessible to the buyer encrypted with its public key.
