Limits

What the widget does not do.

EVM only. The wallet bridge connects and signs on EVM chains; a non-EVM token can be a destination (with a payout address) but not a source.
English only. locale is accepted and forwarded; any other language logs a console warning and the page stays English.
locale, showWallet and the wallet adapter are fixed at initialize().
Fees and referrers. Commission and referrer attribution are set on the page side, not by the host. Options like referrer are ignored.
Token list. The page offers exactly the tokens its deployment lists; a preset token outside it is left empty and reported as TOKEN_NOT_SUPPORTED.
Order recovery. Signing payloads are never restored, so an unsent deposit cannot be resumed after a reload. An order that was created can be reopened by its id with config.orderId.

The SDK, its protocol and a demo host page live in packages/sdk of this repository.
