Function: getTokenDecimals()

getTokenDecimals(symbol, chain): number

Defined in: @sip-protocol/sdk/dist/index-DXh2IGkz.d.ts:7081

Get token decimals by symbol and chain

Parameters

symbol

string

Token symbol (e.g., ‘USDC’, ‘SOL’, ‘ETH’)

chain

ChainId

Chain identifier

Returns

number

Number of decimals for the token

Throws

If token is unknown

Example

// Correct usage - always lookup decimals
const decimals = getTokenDecimals('USDC', 'solana')  // 6
const solDecimals = getTokenDecimals('SOL', 'solana')  // 9
const ethDecimals = getTokenDecimals('ETH', 'ethereum')  // 18

// This prevents the common bug of hardcoding 9:
// WRONG: decimals: 9
// RIGHT: decimals: getTokenDecimals(symbol, chain)
