Package common provides shared realm utilities for GnoSwap protocol contracts.
The package contains helpers that must keep a realm boundary, including GRC20 token operations and native coin validation. AMM math lives in gno.land/p/gnoswap/gnsmath/v1.
Key components: - GRC20 Registry Helpers: convenient wrappers for GRC20 token operations - Coin Utilities: native coin handling and validation - Assertion Utilities: input validation for supported operations, including native-coin rejection
AssertIsNotHandleNativeCoin validates that no native coins were sent with the transaction.
Use this when a function should only work with GRC20 tokens and not accept native coins.
