Amnis Staked Aptos Coin

Amnis Staked Aptos coin (STAPT) is a cryptocurrency launched in 2023. A liquid staking derivative, it tracks a proportional claim on staked Aptos (APT) within the Amnis Finance vault—an autocompounding yield instrument built directly on the Aptos blockchain.

The token resolves the classic staking dilemma: assets must lock to secure a proof-of-stake network, yet locked capital cannot move across DeFi. stAPT disarms this friction by minting a liquid, fungible receipt that accrues validator rewards without immobilizing the underlying position. Users can transfer, trade, or collateralize that receipt while the original APT continues earning. The mechanism mirrors established models like Aave’s aTokens or Compound’s cTokens, adapted to Aptos’s Move-based execution.

The asset operates on the Aptos network, functioning as a smart contract token rather than a standalone chain. Its logic executes within the Move virtual machine, inheriting Aptos’s parallel transaction processing and sub-second finality. The contract mints stAPT when a user deposits amAPT—a separate receipt token emitted by Amnis validators—converting one liquid staking wrapper into another that autonomously compounds.

Technically, stAPT adheres to the Aptos Fungible Asset standard, surfaced under the contract identifier 0x111ae3e5bc… The vault’s code algorithmically adjusts the amAPT-to-stAPT exchange rate at every reward distribution epoch, dilating the ratio to reflect accrued validator yield. No manual harvest or re-staking steps exist. The token’s supply floats upward unbounded, though mints and redemptions keep the price pegged close to the value of the underlying APT basket.

Amnis Finance introduced the stAPT vault on October 19, 2023, quickly after the broader acceptance of liquid staking on Aptos. No named founders appear in public documentation; the protocol emerged from a disciplined team focused on validator infrastructure and yield optimization. Within months, stAPT seeded liquidity pools on decentralized exchanges such as Liquidswap and Pontem, embedding itself into the nascent Aptos DeFi stack.

The project’s mission extends beyond mere yield generation. It aims to restructure how staking security is funded: by tokenizing staked positions, Amnis funnels liquidity back into Aptos’s money markets and lending protocols, strengthening total value locked while preserving decentralization. This reframing turns a passive reward stream into a composable building block.

Mechanically, stAPT functions as a vault share. A deposit of amAPT mints a precisely equivalent value in stAPT based on the current exchange rate. The vault receives continuous amAPT emissions from Amnis validators, and those added tokens enlarge the pool. When a user redeems stAPT, the contract burns the shares and returns a greater quantity of amAPT than originally deposited, capturing all interim gains. No governance token supplements this process; stAPT itself is the single yield-bearing instrument.

Stakers who mint stAPT sidestep the 30-day unbonding period typical of native Aptos staking, gaining instant exit liquidity. Liquidity providers can pair stAPT with stablecoins or APT in constant-product pools, collecting swap fees atop autocompounded yield. Lenders supply stAPT to isolated money markets, borrowing other assets against their appreciating position—an operation impossible with raw staked APT. These scenarios map directly to capital efficiency strategies in a high-velocity DeFi environment.

Amnis Staked Aptos coin has a maximum supply of 18,422,870.60 tokens. Currently, 2,016,038.30 STAPT are in circulation. The token does not feature a halving schedule or programmed burn; its supply expands only when users deposit amAPT into the vault and contracts when they redeem. With a market capitalization of $2,362,569.00, Amnis Staked Aptos coin ranks #8,385 among all cryptocurrencies.
