How are LP tokens burned in XRP Ledger?

Unveiling the Process of Burning LP Tokens in XRP Ledger

In the realm of decentralized finance, burning liquidity provider (LP) tokens in automated market makers (AMMs) plays a significant role. Join us as we delve into the mechanics of this process within the XRP Ledger (XRPL) ecosystem.

Understanding AMMs and LP Tokens

Automated market makers, such as XRPL’s decentralized exchange, enable the trading of assets without the need for intermediaries. Liquidity providers contribute assets to these AMMs and receive LP tokens in return. Each AMM pairs two assets, one of which can be XRP, allowing users to swap assets at exchange rates determined by a formula.

Deposit Authorization and AMM Accounts

Neil Hartner, a senior software engineer at Ripple, shed light on the unique aspect of AMM accounts on XRPL: they have the “DepositAuth flag” enabled, preventing anyone from sending them XRP or token payments. This not only safeguards against accidental payments but also implies that AMM accounts are ineligible for issuer-initiated airdrops.

Burning LP Tokens

David Schwartz, Ripple’s CTO, outlined the correct procedure for burning LP tokens in XRPL AMMs. According to Schwartz, LP tokens can be effectively burned by “overpaying in the slot auction.” This approach ensures that the valuation of the pool remains accurate. Burning LP tokens involves sending them to a “burner account,” which removes them from circulation and reduces the total supply.

Rationale Behind LP Token Burning

LP tokens can represent unused liquidity in AMMs, which can negatively impact the efficiency of the protocol. Projects may engage in “burning” LP tokens to reduce the circulating supply and align the token distribution with their desired usage. By doing so, they aim to optimize capital allocation and enhance the overall functionality of the AMM.

Examples of LP Token Burning

• Flare: The Flare project announced plans to burn 35% of its unused LP tokens, valuing around $25 million, to reinforce the ecosystem’s long-term viability.
• RippleX: Ripple’s independent organization, RippleX, intends to burn 1 billion XRP from the XLS-20d distribution fund to incentivize the creation of decentralized applications on XRPL.

Conclusion

Burning LP tokens in XRPL AMMs is a crucial mechanism for optimizing liquidity allocation and aligning the token distribution with project objectives. By understanding the process and the involved concepts, users can effectively navigate the XRP Ledger ecosystem and contribute to its growth.
