Lifinity

Lifinity was a decentralized exchange (DEX) on Solana, not the Lifinity Rx health brand that shares the name. It is no longer running. Its token holders voted to shut it down in December 2025. The treasury was turned into USDC for people who hold LFNTY, xLFNTY or veLFNTY, and you can claim until December 31, 2026. After that, Lifinity says all support ends, including its website.

While it ran, Lifinity called itself the first proactive market maker on Solana. It set prices from a live price feed, called an oracle, and not from the mix of tokens in its pools.

How to claim USDC for LFNTY, xLFNTY and veLFNTY before December 31, 2026

You claim on the official page at lifinity.io/claim. Connect the Solana wallet that holds your tokens, then convert them to USDC. The last day is December 31, 2026.

Claims opened on December 29, 2025, the team said on X. It has posted regular reminders since. The November 2026 reminder said two months were left.

The claim program swaps xLFNTY for USDC. Before claims opened, holders of LFNTY or veLFNTY were advised to convert to xLFNTY first, ChainCatcher reported.

When the vote passed, community estimates cited by ChainCatcher put the payout at about $0.90 to $1.10 per token. The final rate depended on what the treasury's assets fetched when they were swapped into USDC.

If you hold LFNTY in a wallet you rarely open, check it before the year ends. Use only the lifinity.io site, and check the token's mint address, as the risk section below explains.

How the oracle-based AMM priced trades

Lifinity took its prices from Pyth Network PYTH$0.067+2.3% feeds. Most automated market makers, or AMMs, set a price from the ratio of tokens in a pool. When the market moves, traders buy the cheap side until the pool catches up. The people who supplied the pool take that loss, which is called impermanent loss.

Lifinity's pools quoted close to the oracle price instead. That left traders much less of a gap to profit from.

The documentation lists three parts. Liquidity sat close to the oracle price on its own, so nobody had to set price ranges. The oracle was the main price input, which the docs say "reduces or even reverses impermanent loss". And pools were rebalanced on a delay, which Lifinity said is how it made money from market making.

The idea came from a co-founder known as Luffy. Before Lifinity he had built a farming bot for Raydium, the team told Pyth Network in August 2022. He saw that supplying a pool is like betting the tokens rise and that prices stay calm. A good price feed could replace the traders who usually fix the pool's price.

The team set each pool's fee by hand. The fee page says fees were set "with the aim of maximizing profitability".

Lifinity v2 and the delta-neutral market maker

Lifinity v2 changed what a pool tries to hold. A first-version pool kept equal value in its two tokens. A v2 pool tries to keep the same amount of its main token that it started with. It only resets that target when the price moves past a set point.

Holding a fixed amount of one token makes the price risk easy to offset. The protocol could borrow that token, or bet against it with perpetual futures. Either one cancels most of the pool's exposure to price swings. Lifinity called this design a Delta Neutral Market Maker.

Protocol-owned liquidity: could you provide liquidity on Lifinity?

You could not add your own funds to a Lifinity pool. The docs say every pool was closed to deposits. All the money in the pools belonged to the protocol, and it backed the LFNTY token.

This is the main way Lifinity differed from other exchanges. It funded every pair from its own treasury. Trading fees and market making profit went to the protocol, and from there to token holders. Under the revenue rules, 70% of fee income went to veLFNTY holders.

Lifinity also offered its market making to other projects. Under Market Making as a Service, a project put up the tokens and kept any market making profit, while Lifinity kept the fees. Under Liquidity as a Service, Lifinity put up the tokens and took the price risk. The project paid Lifinity based on trading volume. Both needed a custom price feed for the project's token.

LFNTY, veLFNTY and xLFNTY tokenomics and the veIDO

LFNTY was Lifinity's governance token. You could lock it for anything from a week to four years to get veLFNTY. veLFNTY gave you votes and a share of revenue, but you could not send it to anyone.

The longer the lock, the more veLFNTY you got, per the token docs. Lock 100 LFNTY for four years and you got 100 veLFNTY. Lock it for one year and you got 25.

xLFNTY was a tradable version of a four-year veLFNTY lock. It swapped one for one with veLFNTY.

LFNTY launched through a veIDO on April 23, 2022. This was a token sale where buyers picked a lock period up front. Longer locks bought tokens at a bigger discount, and deposits could not be taken back. The sale raised about 9.67 million USDC, and most of it became the protocol's own liquidity.

Flares NFTs and the 2023 Flare DAO buyout

Flares were a set of 10,000 animated NFTs. Money from the sale went into Lifinity's pools, per the docs. Trading fees and NFT royalties paid for buybacks of Flares. A buyback started on its own if Flares fell below half the mint price. Flare holders also received 1% of the LFNTY supply.

In July 2023, Lifinity DAO bought Flare DAO's pool funds and paid in LFNTY. Flare DAO then locked that LFNTY as veLFNTY. In the wind-down, ChainCatcher reported, Flare DAO was left to decide what to do with its own share of the USDC.

Why Lifinity shut down: the December 2025 vote

Lifinity closed because it could no longer keep up. Trading on Solana had become too hard to win, Cryptopolitan reported. It named Raydium, Orca and Phoenix as the venues that took over. ChainCatcher pointed to prop AMMs. Lifinity paid for all its own pools, so it earned only what its own trades brought in.

It had been a big venue. Lifinity handled about $150 billion in trades over its life, per Cryptopolitan. That made it the fifth-largest DEX in Solana's history.

The team put the closure to an on-chain vote in December 2025. On December 18 it said the vote had passed. It said it would write the program that swaps xLFNTY for USDC and have it audited before claims opened.

The DAO treasury, about $42 million, was swapped into USDC. Money left in the development fund brought the payout to about $43.4 million, according to Cryptopolitan.

Solana's official account called the team "true Solana pioneers that did right by their users to the very end."

Who Lifinity is for now: holders with unclaimed USDC

Lifinity now matters to one group: people who still hold LFNTY, xLFNTY or veLFNTY. You have until December 31, 2026 to convert. After that, the claim site and support are set to end.

If you want to swap tokens or earn fees on your own funds, use a live exchange. Lifinity no longer runs trading, and it never let outsiders fund its pools. Builders may still find its docs useful while the site is up. They show an early Solana exchange that priced from a feed and owned all its own liquidity.

Risks: the claim deadline, copycat LFNTY tokens and audits

The biggest risk is missing the deadline. Lifinity says support and the website end after December 31, 2026. A holder who waits past that may have no way to convert.

The second risk is fake tokens. Several pump.fun-style tokens on Solana use the LFNTY ticker and the Lifinity name. Only the mint that starts LFNTYraet is the real LFNTY, as shown in the table above. Check the mint before you trade or claim, and use only the lifinity.io claim page.

On audits, ChainCatcher reported that the claim was due to go live after a Sec3 security audit of the xLFNTY-to-USDC program. That audit covers the claim program only. Lifinity's docs do not link audit reports for its two swap programs.

The design had its own risks while it ran. Pools leaned on Pyth prices, so a wrong price feed would have meant wrong trade prices. And all the liquidity was the protocol's money, so any pool losses fell on the treasury and its token holders. Before you sign a transaction with a Lifinity program, you can look up who controls upgrades on a Solana explorer.

Alternatives to Lifinity: Raydium, Orca, Phoenix and prop AMMs

If you want to swap on Solana, the venues that took Lifinity's trading are the plain choices. Raydium and Orca are AMMs where anyone can add funds to a pool. Phoenix is an on-chain order book that also gained share as Lifinity shrank.

The closest heirs to Lifinity's design are prop AMMs, short for proprietary AMMs. Each is run by one market maker that sets its own prices, much as Lifinity used a price feed. Swap aggregators such as Jupiter send trades to them. DWF Ventures research we covered in September 2026 found they carried a large share of on-chain DEX trading.
