TS: Pooled Accounts

Handling muxed deposits in TypeScript.

Pooled accounts are a common pattern for exchanges and fintech apps. This guide shows how to handle them safely in TypeScript.

The Problem

JavaScript’s Number type is a 64-bit float, which cannot safely represent all 64-bit integers (specifically those above 2^53 - 1).

The Solution

Stellar Address Kit always returns the routingId as a string to avoid any precision loss.

import { extractRouting } from 'stellar-address-kit';

const result = extractRouting({
  address: "MA7Q...QD"
});

// ALWAYS use the string value for DB lookups
const userId = result.routingId; 

if (result.warnings.some(w => w.code === 'JS_PRECISION_LOSS')) {
  // This would trigger if you tried to pass a number that was too large
}
