The XRP Ledger now has a native Automated Market Maker (AMM) built directly into the protocol. This isn't a smart contract that could be hacked—it's part of the ledger itself. For XRP holders looking to put their tokens to work, understanding AMM pools is essential.
What is the XRPL AMM? The XRPL AMM is an Automated Market Maker built directly into the XRP Ledger protocol. It allows trustless token swaps and liquidity providing without smart contract risk. Liquidity providers earn trading fees, typically 5-20% APY depending on volume.

What Is the XRPL AMM?
An Automated Market Maker (AMM) is a type of decentralized exchange that uses liquidity pools instead of order books. Instead of matching buyers and sellers, trades happen against a pool of tokens.
The XRPL AMM launched in 2024 as a protocol upgrade (XLS-30). Unlike AMMs on other blockchains (like Uniswap on Ethereum), the XRPL AMM is not a smart contract—it's a native ledger feature. This distinction matters significantly for security.
Key Features
- Protocol-Level Security: No smart contract bugs possible.
- Low Fees: Standard XRPL transaction costs (~$0.0002).
- Fast Settlement: Trades finalize in 3-5 seconds.
- No MEV: XRPL consensus prevents front-running attacks.
- Continuous Liquidity: Always available to trade, 24/7.
How AMM Pools Work
AMM pools use a mathematical formula to determine prices. The XRPL AMM uses a variation of the constant product formula, similar to Uniswap V2.
The Basic Math
Each pool holds two tokens (e.g., XRP and USD). The formula x × y = k maintains the relationship:
- x = amount of Token A in the pool
- y = amount of Token B in the pool
- k = constant (stays the same after trades)
When someone trades XRP for USD, they add XRP to the pool and remove USD. The formula automatically adjusts prices to maintain the constant k.
Price Discovery
The ratio of tokens in the pool determines the price. If a pool has 1,000 XRP and 2,000 USD, the implied price is $2 per XRP. As people trade, this ratio changes, and so does the price.
Large trades move the price more (called "slippage"). Pools with more liquidity have less slippage, making them better for larger trades.
Trading Fees
Each trade pays a small fee (typically 0.3% on most pools). This fee goes to liquidity providers proportional to their share of the pool. It's how LPs earn yield.
How do XRPL AMM pools work? AMM pools hold two tokens and use a mathematical formula (x*y=k) to determine prices. Traders swap against the pool, paying a small fee that goes to liquidity providers. The token ratio automatically adjusts based on supply and demand.
Providing Liquidity
Anyone can become a liquidity provider (LP) by depositing tokens into a pool. Here's how:
Step 1: Choose a Wallet
You need an XRPL wallet that supports AMM operations. Popular options include:
- XUMM: Most popular mobile wallet with full AMM support.
- GemWallet: Browser extension wallet.
- Crossmark: Browser extension with clean interface.
Step 2: Select a Pool
Choose which trading pair you want to provide liquidity for. Consider:
- Trading Volume: Higher volume = more fees earned.
- Token Volatility: More volatile pairs have higher impermanent loss risk.
- Your Holdings: Use tokens you already own and believe in.
Step 3: Deposit Both Tokens
You must deposit equal USD value of both tokens. If XRP is $2 and you deposit 100 XRP ($200), you also need $200 worth of the other token.
Step 4: Receive LP Tokens
After depositing, you receive LP tokens representing your share of the pool. These tokens are essential—you need them to withdraw your liquidity later.
Step 5: Earn Fees
Your pool share automatically earns a portion of all trading fees. There's nothing else to do—fees compound into your position automatically.
Yields and Trading Fees
LP returns come from trading fees. Let's understand the math:
Fee Structure
XRPL AMM pools have configurable fees, but most use 0.3% (similar to Uniswap). This means:
- Every $10,000 trade generates $30 in fees.
- Fees are distributed proportionally to all LPs.
- If you own 1% of the pool, you get 1% of fees.
Calculating APY
APY depends on trading volume relative to pool size:
| Daily Volume | Pool Size | Daily Fees | Approx. APY |
|---|---|---|---|
| $100,000 | $1,000,000 | $300 | ~11% |
| $500,000 | $1,000,000 | $1,500 | ~55% |
| $50,000 | $1,000,000 | $150 | ~5.5% |
*Actual returns vary. These are illustrative examples only.
Realistic Expectations
Most established pools yield 5-20% APY from fees. Be skeptical of claims above 50%—they often indicate low liquidity (high risk) or are unsustainable.
Understanding Impermanent Loss
Impermanent loss (IL) is the main risk of liquidity providing. It's called "impermanent" because it only becomes permanent when you withdraw.
What Causes IL?
When token prices change, the AMM formula automatically rebalances your position. If XRP price doubles:
- Arbitrageurs buy XRP from the pool (cheap relative to market).
- The pool ends up with more USD and less XRP.
- Your position has grown in USD terms, but less than if you just held XRP.
IL Examples
| Price Change | Impermanent Loss |
|---|---|
| 25% (1.25x or 0.8x) | ~0.6% |
| 50% (1.5x or 0.67x) | ~2.0% |
| 100% (2x or 0.5x) | ~5.7% |
| 200% (3x or 0.33x) | ~13.4% |
| 400% (5x or 0.2x) | ~25.5% |
When IL Becomes Permanent
IL is only "realized" when you withdraw. If you stay in the pool and prices return to original levels, the loss disappears. Many LPs accept IL as the cost of earning trading fees.
Mitigating IL
- Choose stable pairs: XRP/USD has less IL than XRP/volatile-token.
- Long-term view: Fees may exceed IL over time.
- Don't panic withdraw: Wait for prices to stabilize.
What is impermanent loss in AMM? Impermanent loss occurs when pooled token prices change. If XRP doubles while you are providing liquidity, you end up with less value than simply holding. The loss is 'impermanent' because it reverses if prices return. Trading fees can offset IL over time.
Why Native AMM Is Safest
The XRPL AMM has a crucial advantage over other blockchain AMMs: it's not a smart contract.
No Smart Contract Risk
Smart contracts can have bugs that hackers exploit. Billions of dollars have been lost to DeFi hacks on Ethereum and other chains. The XRPL AMM has no smart contract—the code is part of the ledger protocol itself, reviewed and approved by the XRPL validator network.
No Admin Keys
Many DeFi protocols have admin keys that could be compromised. The XRPL AMM has no admin—it's fully decentralized and controlled by the protocol rules.
Battle-Tested Ledger
XRPL has operated continuously since 2012 with no downtime or security breaches at the protocol level. The AMM inherits this security track record.
What Risks Remain
While the AMM itself is safe, risks remain:
- Impermanent Loss: Price movement risk (not a bug, by design).
- Token Risk: If the non-XRP token you pair with fails, your position loses value.
- Wallet Security: Your wallet could be compromised (use hardware wallets).
Popular XRP Pools
Several pools have emerged as favorites for XRP liquidity providing:
XRP/USD Stablecoin Pools
Pairing XRP with stablecoins (like USD tokens issued on XRPL) is popular because:
- High trading demand (people buy/sell XRP for dollars).
- Moderate IL (only XRP price moves, not both tokens).
- Consistent fee generation from regular trading.
XRP/Token Pools
Pools pairing XRP with other XRPL tokens (like SOLO, Coreum, etc.) offer:
- Potentially higher fees (newer, less efficient markets).
- Higher IL risk (both tokens can move).
- Exposure to other ecosystem projects.

Frequently Asked Questions
How much XRP do I need to start?
There's no minimum, but remember you need to deposit both tokens in the pair. Start with an amount you're comfortable locking up while you learn. Even $100-500 is fine for testing.
Can I lose all my XRP in an AMM?
You can't lose it all to hacks (protocol-level security). You could lose significant value to impermanent loss if prices move dramatically, or if the paired token collapses. You always get something back when withdrawing.
How often are fees paid?
Fees accumulate continuously with each trade. They're automatically added to your pool position—you don't need to claim them separately.
Can I withdraw anytime?
Yes. Unlike some DeFi protocols with lock-up periods, XRPL AMM withdrawals are instant. Just burn your LP tokens to receive your share of the pool.
What happens if trading stops?
If no one trades, you earn no fees. Your position just sits there. You can withdraw anytime regardless of trading activity.
Is it better than staking?
Different risk/reward profiles. AMM LP can earn higher yields but carries IL risk. Staking (where available) offers more predictable returns. Many users do both.
The Bottom Line
The XRPL AMM offers a unique opportunity: DeFi yields with protocol-level security. No smart contract bugs, no admin keys, just math and market forces.
For XRP holders looking to put their tokens to work, understanding AMM pools is increasingly important. Start small, learn the mechanics, and decide if the yields justify the impermanent loss risk for your situation.
