What is Ampleforth (AMPL)?
Quick Facts
- Token symbol: AMPL
- Blockchain: Ethereum (ERC-20), with bridges to BNB Chain and more
- Price target: CPI-adjusted 2019 US dollar (~$1)
- Supply mechanism: Daily algorithmic rebase
- Governance token: FORTH
- Oracle provider: Chainlink decentralized oracle network
- Liquidity program: Ampleforth Geyser
Introduction
Ampleforth (AMPL) is a unique digital currency designed to maintain long-run price stability — not through collateral or reserves, but through automatic supply adjustments. Every day, the protocol expands or contracts the number of AMPL tokens across all wallets proportionally, seeking to drive the price back toward its target.
This makes AMPL fundamentally different from both fixed-supply cryptocurrencies like Bitcoin and collateral-backed stablecoins like DAI.
History & Background
Ampleforth was founded by Evan Kuo, an entrepreneur and UC Berkeley graduate with a background in mechatronics and robotics. The project launched its mainnet rebase mechanism in 2019, making AMPL one of the earliest elastic-supply tokens in the DeFi ecosystem.
The protocol later integrated Chainlink decentralized oracles to decentralize its daily price-data feeds, reducing reliance on any single data source and improving resilience against manipulation.
How Ampleforth Works
At the heart of AMPL is the rebase — a once-daily automated event (around 02:00 UTC) that adjusts token balances across every wallet simultaneously.
- Expansion: If AMPL trades above its target, balances increase proportionally.
- Contraction: If AMPL trades below its target, balances decrease proportionally.
- Equilibrium: If AMPL is near target, no adjustment occurs.
Critically, rebases are non-dilutive: a holder who owns 1% of total AMPL supply before a rebase will still own 1% after it. Chainlink oracles supply two data feeds — a volume-adjusted AMPL/USD market price and a monthly CPI reading — which the protocol compares to calculate each rebase magnitude.
Tokenomics
AMPL's economic design is built around supply elasticity rather than price volatility. Instead of price swings absorbing demand shocks, the token count in each wallet absorbs them. This means contracts denominated in AMPL remain relatively stable in the long run, even as short-term wallet balances fluctuate.
The FORTH token handles governance for the Ampleforth protocol, keeping AMPL itself focused purely on its monetary role.

Ecosystem & Use Cases
AMPL has several practical applications within DeFi:
- Lending and borrowing — AMPL is available as a lend-and-borrow asset on AAVE.
- On-chain derivatives — Contracts denominated in AMPL offer long-run price stability.
- Liquidity provision — The Geyser program rewards liquidity providers who stake LP tokens from AMPL trading pairs on decentralized exchanges.
- Portfolio diversification — Because AMPL's supply mechanics create unique price behavior, it can act as a low-correlation asset relative to BTC and ETH.
Team, Governance & Community
The Ampleforth Foundation oversees protocol development, led by CEO Evan Kuo. Day-to-day governance decisions are made by FORTH token holders, enabling decentralized control over protocol parameters. The community is active across Telegram, Twitter, and GitHub, where the protocol's smart contracts are open-source.
Advantages
- Non-dilutive supply changes — Proportional rebases preserve each holder's share of the network.
- No collateral required — Stability is maintained by market incentives alone, not locked assets.
- Decentralized oracle integration — Chainlink feeds reduce centralization risk in daily rebases.
- DeFi composability — AMPL works as a building block for loans, derivatives, and liquidity pools.
Risks & Challenges
- Wallet balance volatility — Daily token count changes can be confusing and disorienting for new users.
- Rebase complexity — Managing AMPL in DeFi protocols requires platforms to support its elastic balance model.
- Adoption risk — Achieving widespread use as a unit of account depends on broader ecosystem acceptance.
- Oracle dependency — The accuracy of rebases relies on the integrity of external price and CPI data feeds.
Long-Term Vision
Ampleforth's primary ambition is to serve as a decentralized, inflation-resistant unit of account — an alternative to fiat-denominated finance that does not rely on central banks, collateral, or trusted intermediaries. By transferring demand volatility into supply changes rather than suppressing it, the protocol aims to create a programmable monetary primitive that can underpin stable contracts, loans, and derivatives natively on-chain.
Frequently Asked Questions
- What is a rebase in Ampleforth?
A rebase is a daily automated event where the Ampleforth protocol proportionally adjusts the number of AMPL tokens in every wallet to push the market price toward its target. If AMPL is trading above target, balances increase; if below, they decrease.
- Does a rebase dilute my AMPL holdings?
No. Rebases are non-dilutive, meaning your percentage ownership of the total AMPL supply stays exactly the same before and after each rebase. Only your token count changes, not your share of the network.
- What is AMPL's price target?
AMPL targets a price equal to the CPI-adjusted 2019 US dollar, which is approximately $1. The target slowly adjusts over time to account for inflation as measured by the Consumer Price Index.
- How does Ampleforth differ from other stablecoins?
Unlike collateral-backed stablecoins, AMPL requires no locked assets or reserves to maintain stability. Instead, it uses algorithmic supply adjustments driven entirely by market incentives and decentralized oracle data.
- What is the FORTH token?
FORTH is Ampleforth's governance token, separate from AMPL. FORTH holders vote on protocol parameters and upgrades, allowing the community to control the direction of the Ampleforth ecosystem.
- What is the Ampleforth Geyser?
The Geyser is a liquidity incentive program where users who provide liquidity to AMPL trading pairs on decentralized exchanges can stake their LP tokens to earn additional AMPL rewards.
- Which blockchains support AMPL?
AMPL is native to Ethereum but is also bridged to BNB Smart Chain, Avalanche DFK, and NEAR, allowing it to be used across multiple DeFi ecosystems.
- Can AMPL be used for lending and borrowing?
Yes. AMPL is available as a lending and borrowing asset on AAVE, one of the largest DeFi lending protocols, making it usable as a DeFi financial primitive beyond simple trading.
