Rampart provides a unified interface to all LST protocols on Monad, covering native liquid staking, restaking vaults, yield-optimized wrappers, and multi-protocol yield aggregators.

​
Overview

Monad’s liquid staking ecosystem lets holders earn staking rewards while keeping their MON liquid. Each LST protocol takes a different approach - from simple 1:1 staking to complex restaking vaults and yield aggregation. Rampart normalizes access to all of them through consistent TypeScript functions.

Aggregated Access

Pull stats from all LSTs in a single call using the LST aggregator: 
import { Rampart } from 'rampart-monad'

const sdk = new Rampart()

// All 5 LSTs sorted by APR
const all = await sdk.compareLSTs()
// → [{ token: 'vshMON', apr: 0.09, protocol: 'mellow', ... }, ...]

// Highest APR LST right now
const best = await sdk.getBestLST()
// → { token: 'vshMON', apr: 0.09, protocol: 'mellow', tvl: 19000000, ... }

// Total MON staked across the entire ecosystem
const total = await sdk.getTotalStakedMON()
// → 137000000 (in MON)

Architecture Notes

All LST functions are available both as standalone imports and as methods on the Rampart class. The RampartAgent exposes them as AI tools for use with the Vercel AI SDK.
  • aprMON - aPriori’s ERC4626 vault; exchange rate increases as staking rewards accrue
  • gMON - Kintsu uses a uint96 rate stored on-chain; APR derived from 500k-block delta
  • shMON - FastLane’s validator MEV-boosted staking token; wrapped as vshMON by Mellow
  • vshMON - Mellow vault holding shMON; adds a second yield layer on top of FastLane rewards
  • sMON - Magma’s straightforward liquid staking with competitive base APR
