TVL: ~$48M | Type: Liquid Staking | Docs: apriori.xyz

​
Overview

aPriori is the largest liquid staking protocol on Monad by TVL. Users deposit MON and receive aprMON, an ERC4626 vault token whose exchange rate increases continuously as staking rewards accrue. There is no manual claim step - rewards are automatically reflected in the aprMON/MON rate. The aPriori pool contract acts as both the ERC4626 vault and the staking manager. The previewRedeem function gives the current redemption rate without any gas cost.

​
Functions

​
getAPrioriLST()

Returns the full LSTStats snapshot for aprMON. 
import { Rampart } from 'rampart-monad'

const sdk = new Rampart()
const lst = await sdk.getAPrioriLST()
// → LSTStats

console.log(`aprMON APR: ${(lst.apr * 100).toFixed(2)}%`)
console.log(`Exchange rate: 1 MON = ${lst.exchangeRate} aprMON`)
console.log(`TVL: $${(lst.tvl / 1e6).toFixed(1)}M`)

​
getAPrioriExchangeRate()

Returns the current aprMON/MON exchange rate as a plain number. This is derived from previewRedeem(1e18) on the pool contract. 
const rate = await sdk.getAPrioriExchangeRate()
// → number, e.g. 1.082

console.log(`1 aprMON redeems for ${rate.toFixed(4)} MON`)

​
getAPrioriTVL()

Returns the total MON deposited into the aPriori pool, denominated in USD using the current MON price. 
const tvl = await sdk.getAPrioriTVL()
// → number (USD)

console.log(`aPriori TVL: $${(tvl / 1e6).toFixed(1)}M`)

​
getStakingAPR()

Returns a StakingAPR object with the annualized percentage rate for aprMON computed from the exchange rate delta over the last 500k blocks (~56 hours on Monad). 
import { getStakingAPR } from 'rampart-monad'

const apr = await getStakingAPR('apriori')
// → { token: 'aprMON', apr: 0.08, basis: 'exchange-rate-delta', protocol: 'apriori' }

console.log(`APR: ${(apr.apr * 100).toFixed(2)}%`)

Contract Addresses

ContractAddress
aprMON token / aPrioriPool0xb2f82D0f38dc453D596Ad40A37799446Cc89274A
The aprMON token address and the aPriori pool address are the same contract - it is a unified ERC4626 vault.
