aprMON — the smallest of Monad's four liquid-staking tokens by TVL, but read on-chain with the same rigor as the others.
aPriori issues aprMON, another ERC-4626 liquid-staking vault for MON — deposit MON, receive aprMON, and the vault's exchange rate climbs as staking rewards accrue while aprMON itself stays usable elsewhere in DeFi.
Same direct on-chain read as shMonad and Magma: a batched Multicall reads `totalSupply()`, `totalAssets()` and `convertToAssets(1e18)` on a regular cadence, with the same automatic fallback to a plain division if the preferred call fails. The rate is snapshotted hourly into the same historical store all three ERC-4626 LSTs share, and APY is derived the same way — annualized real rate growth over the widest available window up to 7 days, returned as no figure at all rather than a guess if there isn't yet enough growth or history to compute one honestly.
aPriori is currently the smallest of Monad's four LSTs by TVL, which typically means the thinnest secondary-market liquidity of the group — a wider gap between its true redemption rate and what a DEX sale would actually realize during a fast move, purely as a function of size rather than any flaw specific to the protocol. The same validator-level risk (slashing, downtime) applies as with any Monad LST.
Yes — identical methodology: a direct on-chain convertToAssets() read via Multicall, hourly rate snapshots, and APY computed from real observed rate growth over up to a 7-day window. All three are ERC-4626 vaults read the same way; only Kintsu's sMON differs.
It's currently the smallest of Monad's four tracked LSTs by TVL — smaller size generally correlates with thinner secondary-market DEX liquidity, meaning a bigger potential gap between the true on-chain redemption rate and what selling into the market would actually realize during a fast move.
