Read-only & non-custodial

No private keys. Backend-safe verification against public Mirror Node data.

Decimal-safe

bigint money end-to-end. No floating point. tinybars and HTS decimals handled correctly.

Every edge case

Exact, partial, over, duplicate, wrong-memo, wrong-token, out-of-window — all explicit.
