Token registration (NEP-141)

TL;DR

• Token contracts require storage registration before they can store balances for an account.
• In this app, both wallet and vault may need registration depending on the flow.
• The UI checks this and surfaces one-click registration actions.

Why it matters

Without registration, token transfers to or from that account can fail.

Where it appears in the app

• Opening a request: vault registration check for the request token.
• Funding a request: lender wallet and vault registration checks.
• Repay top-up flow: owner wallet and vault registration checks.
• Registration actions call storage_deposit with registration_only: true.

Manual flow (reference)

1. Read storage_balance_bounds on the token.
2. Call storage_deposit with the target account ID.
3. Attach at least the minimum required deposit.
4. Retry the original action.

Tip

Use explorer links from dialogs/cards to confirm token account IDs and registration targets.
