Smart Contract Integration

Overview

This guide is intended for developers integrating with aPriori’s liquid staking protocol.

aprMON - Reward Bearing LST

aprMON is a reward-bearing liquid staking token. This means that it does not automatically adjust the number of tokens in circulation. Instead, the token’s value increases as rewards are generated. When you hold a reward-bearing token, you maintain the same number of tokens in your wallet, but the value of those tokens increases over time as the staking rewards accumulate.

Functions

1. Fetch Exchange Rate

To fetch the current aprMON/MON exchange rate you need to invoke the convertToAssets function(i.e. how many MON you get back for certain amount of aprMON):

uint256 assets = aprMON.convertToAssets(1 ether)

To fetch the current MON/aprMON exchange rate you need to invoke the convertToShares function(i.e. how many aprMON you get back for certain amount of MON):

uint256 shares = aprMON.convertToShares(1 ether)

Note that exchange rate will be 1e18 for now on testnet before Monad staking module is ready. So MON-aprMON will be a 1-to-1 pair.

2. Fetch Balance

To fetch the aprMON balance of a user use the balanceOf function:

balanceOf(address account) external view returns (uint256 balance)

3. Stake

To deposit Monad into aPriori and mint aprMON you need to invoke the deposit function:

deposit(uint256 assets, address receiver)

Deposits immediately mint aprMON tokens with the current exchange rate.

4. Unstake

To request a withdrawal you need to call the requestRedeem function:

requestRedeem(uint256 shares, address controller, address owner) external returns (uint256 requestId)

Withdrawals requests take a few staking module epochs to be claimable. Each staking module epoch is roughly 5.5 to 6 hours, thus the expected wait time for a withdrawal request is usually around 12-18 hours. Once the time has lapsed you can call the function redeem(uint256 requestId, address receiver) function to receive the Monad tokens.
