SDK Errors

Common errors encountered when using the SwapX SDKs.

"Invariant failed: RATIO"

Cause: You are trying to create a Price or Fraction with an invalid denominator (zero) or inconsistent types. Fix: Check that your token reserves are not zero.

"Invariant failed: ADDRESSES"

Cause: You are trying to create a Pair or Pool with identical token addresses, or sorting failed. Fix: Ensure TokenA and TokenB have different addresses.

"Unsupported Chain ID"

Cause: The SDK default configurations might not include the SwapX Testnet ID (33772211) by default in some check functions if they rely on hardcoded lists. Fix: Always pass the explicit chainId or ChainId object if available. When using Token, ensure you pass 33772211.
