Memo chains

Some chains need a memo next to the deposit address. Sending without it can make a deposit unrecoverable.

Stellar

Stellar is currently the only chain that needs a memo. The modal requests the right deposit mode automatically and shows the memo prominently next to the deposit address, with its own copy button.

Trustlines

Non-native Stellar assets, such as Stellar USDC, need the receiving address to have a trustline for that asset, or funds can’t be delivered. The modal warns about this when a payer enters a refund address for a non-XLM Stellar token.

TON and XRP

The 1Click API’s documentation suggests TON and XRP may also need memos. Tested against the live API, they don’t for the chains Uniport supports today. Only Stellar does.
