@lunarbase-lab/pmm-v2-math

Pure TypeScript bigint quote math with Solidity-compatible results.

Status: fully supported.

Install

npm install @lunarbase-lab/pmm-v2-math

Use

import {
  quote,
  solidityQuoteAmount,
  type QuotePolicy,
  type QuoteRequest,
  type QuoteState,
} from "@lunarbase-lab/pmm-v2-math";

const policy = { feeClass: "Whitelisted" } satisfies QuotePolicy;
const outcome = quote(request satisfies QuoteRequest, executionBlock, state satisfies QuoteState, policy);
const contractAmount = solidityQuoteAmount(request, outcome);

The root entry point is intentionally limited to quotes, quote state, and canonical address helpers. Import optional low-level facilities explicitly:

import { fullMulDivDown } from "@lunarbase-lab/pmm-v2-math/arithmetic";
import { decodeLaneSlot0, modelQuoteToLaneSlot0Fields } from "@lunarbase-lab/pmm-v2-math/slot0";

Fee stages and checked implementation primitives are internal details of the bit-exact quote engine.

Guarantees

• Exact-input and exact-output quotes use checked uint256 arithmetic.
• Values used in EVM arithmetic are represented as bigint.
• The package has no RPC, persistence, clock, async-runtime, or network dependency.
