@vsc.eco/crosschain-core

Pure swap math and operation builders for the Magi (VSC) L2 DEX. Zero runtime dependencies, no network calls.

Ports the CLP swap formula from the Altera app and emits the exact L1 ops (transfer + custom_json) that the router expects, so callers can preview, build, and broadcast swaps without any framework.

Install

pnpm add @vsc.eco/crosschain-core

Usage

import {
  calculateSwap,
  getHiveDepositOp,
  getHiveSwapOp,
  CoinAmount,
  MAINNET_CONFIG
} from '@vsc.eco/crosschain-core';

const amount = CoinAmount.fromDecimal('10', 'HBD');

const { expectedOutput, minAmountOut } = calculateSwap(
  amount.raw,
  reserveIn,
  reserveOut,
  100 // 1% slippage, in bps
);

const depositOp = getHiveDepositOp({
  from: 'alice',
  toDid: 'hive:alice',
  amount,
  config: MAINNET_CONFIG
});
