Protocols: aprMON · sMON · gMON · shMON · vshMON | Type: LST Aggregator | Source: on-chain reads via Rampart
Overview
The LST Aggregator normalizes data from all five Monad liquid staking protocols into a consistent LSTStats type. Use it to compare APRs, exchange rates, and TVLs across the entire ecosystem without integrating each protocol separately.
Types
type LSTStats = {
token: 'aprMON' | 'sMON' | 'gMON' | 'shMON' | 'vshMON'
protocol: string
contractAddress: `0x${string}`
apr: number // annualized rate, e.g. 0.08 = 8%
exchangeRate: number // LST per 1 MON
tvl: number // total value locked in USD
risk: 'low' | 'medium' | 'high'
timestamp: number // unix seconds
}
Functions
getAllLSTStats()
Returns stats for all 5 LSTs in a single multicall batch.
import { Rampart } from 'rampart-monad'
const sdk = new Rampart()
const stats = await sdk.getAllLSTStats()
// → LSTStats[] (5 entries, one per token)
console.log(stats.map(s => `${s.token}: ${(s.apr * 100).toFixed(2)}%`))
// aprMON: 8.00%
// sMON: 7.00%
// gMON: 7.50%
// shMON: 6.50%
// vshMON: 9.00%
getBestLST()
Returns the single LST with the highest current APR.
const best = await sdk.getBestLST()
// → LSTStats
console.log(`Best yield: ${best.token} @ ${(best.apr * 100).toFixed(2)}% APR`)
// Best yield: vshMON @ 9.00% APR
compareLSTs()
Returns all LSTs sorted by APR descending. Useful for building yield comparison UIs.
const ranked = await sdk.compareLSTs()
// Print a comparison table
ranked.forEach((lst, i) => {
console.log(
`${i + 1}. ${lst.token.padEnd(6)} ${lst.protocol.padEnd(12)} ` +
`APR: ${(lst.apr * 100).toFixed(2)}% TVL: $${(lst.tvl / 1e6).toFixed(1)}M`
)
})
// 1. vshMON mellow APR: 9.00% TVL: $19.0M
// 2. aprMON apriori APR: 8.00% TVL: $48.0M
// 3. gMON kintsu APR: 7.50% TVL: $25.0M
// 4. sMON magma APR: 7.00% TVL: $30.0M
// 5. shMON fastlane APR: 6.50% TVL: $15.0M
getTotalStakedMON()
Returns the total MON staked across all 5 protocols combined.
const total = await sdk.getTotalStakedMON()
// → number (MON units)
console.log(`Total staked: ${(total / 1e6).toFixed(1)}M MON`)
// Total staked: 137.0M MON
Contract Addresses
| Token | Contract |
|---|
| aprMON | 0xb2f82D0f38dc453D596Ad40A37799446Cc89274A |
| vshMON (Mellow vault factory) | 0xC9Da1Fe5B70e40C60e4028da5b1d7b8BD8e19c82 |
sMON, gMON, and shMON contract addresses are read dynamically from their respective protocol registries. See individual protocol pages for details.
