caseInsensitiveTokenComparison(tokenA, tokenB): boolean

Case-insensitive token comparison with bidirectional matching.

Compares two token symbols while ignoring case differences. Useful for pool matching and token filtering where case normalization is needed.

Consolidated from 8 duplicated patterns in trading/pool matching:

• tokenA.toLowerCase() === tokenB.toLowerCase()
• token0?.toLowerCase() === token1?.toLowerCase()

Parameters

Parameter	Type	Description
tokenA	string	First token symbol to compare
tokenB	string	Second token symbol to compare

Returns

boolean

True if tokens match (case-insensitive), false otherwise

Examples

Basic token comparison

import { caseInsensitiveTokenComparison } from '@gala-chain/launchpad-sdk';

caseInsensitiveTokenComparison('GALA', 'gala');      // true
caseInsensitiveTokenComparison('USDC', 'usdc');      // true
caseInsensitiveTokenComparison('GALA', 'USDC');      // false

Pool token matching

import { caseInsensitiveTokenComparison } from '@gala-chain/launchpad-sdk';

const poolToken0 = 'GALA';
const poolToken1 = 'GUSDC';
const searchToken = 'gala';

if (caseInsensitiveTokenComparison(poolToken0, searchToken)) {
  // This pool contains GALA
}

Filtering positions

import { caseInsensitiveTokenComparison } from '@gala-chain/launchpad-sdk';

const searchSymbol = 'gusdc';
const galaPositions = positions.filter(p =>
  caseInsensitiveTokenComparison(p.token0, searchSymbol) ||
  caseInsensitiveTokenComparison(p.token1, searchSymbol)
);
