GooseFX

GooseFX is a Solana project that began in 2021 as a DeFi trading platform. Today its website offers one thing: staking SOL with its zero-commission validator. Its last DeFi product was GAMMA, an AMM whose fees rise when prices swing. The docs still describe GAMMA, but the app link they give did not load when we checked in early November 2026. The GOFX token still exists on chain, but it barely trades.

Is GooseFX still active?

Partly. The validator is running, while the DeFi side shows little sign of life.

• The validator is live. The GooseFX website offers SOL staking to the "GooseFX - 0% Fees" validator, and Validators.solutions listed it with active stake on 1 November 2026.
• The GAMMA app is offline. The liquidity guide points to app.goosefx.io, which had no DNS record on 2 November 2026. Nor did api-services.goosefx.io, which the docs use for staking yield and supply data.
• Development is quiet. The last commit to the public GAMMA code is dated 10 July 2025. The @GooseFX1 X account posted nothing in the six months to November 2026, as far as our feed could see.

The GAMMA program is still on chain. Jupiter JUP$0.261+4.6% still lists it in its routing labels, so pools with liquidity left may still trade. GooseFX has posted no shutdown notice, so the AMM appears abandoned without being formally closed.

GooseFX validator: commission, MEV and how to stake

The GooseFX validator takes 0% of inflation rewards. Its website says it also takes 0% of MEV tips.

The validator has two addresses, and they are easy to mix up. You delegate to the vote account, which the website links to on Stakewiz. The identity key is what the validator docs call "the validator address".

To stake, open the staking screen in Phantom, Solflare or Backpack. Search for "GooseFX" or paste the vote account, then delegate. A new stake account needs at least 1 SOL.

The stake starts earning at the next epoch boundary, which is never more than about a day away. The website's "2-3 days" figure dates from when epochs ran much longer.

The GooseFX docs say validator income is used to add SOL liquidity to GAMMA pools. With the app offline, we could not confirm that still happens.

The docs also mention goSOL, a GooseFX liquid staking token they say can be swapped on Jupiter and Sanctum CLOUD$0.044+0.6%. They give no mint address. Check the mint against a GooseFX source before buying anything called goSOL.

Live stake, rank and yield are on our validator comparison table.

GooseFX GAMMA: the dynamic-fee AMM

GAMMA stands for Goose Automated Market Making Algorithm. It uses the simple constant-product curve found in most basic DEX pools. What set it apart was the fee.

Per the GAMMA docs and code, the fee rises when prices are volatile or a pool is lopsided, up to 10% of a swap. The aim was to make arbitrage traders pay more in fast markets, which is when liquidity providers lose most to them.

The docs list four other features:

• Fusion lends idle pool funds out on Kamino Finance KMNO$0.037+12.6%, so LPs earn interest as well as swap fees.
• Boosted rewards let a pool pay several extra reward tokens on top of fees.
• Anyone can create a pool, including for Token-2022 tokens. The pool guide puts the cost at 0.04 SOL for account creation.
• A migration tool moves LP positions over from other Solana AMMs.

The docs also describe GAMMA v2, a hybrid design. It checks pool prices against an oracle and sends each swap to whichever curve prices it better. It also moves LP ranges automatically. The docs give no launch date or program address for it, and we found no sign it went live.

GOFX token and staking rewards

GOFX is the GooseFX token. It went live in November 2021.

The GOFX mint address is GFX1ZjR2P15tmrSwow6FjyDYcEkoFb4p4gJCpLBjaxHD.

Under the fee-share scheme, GAMMA fees were swapped to USDC and paid to people who staked GOFX. Rewards could be claimed daily, and unstaking came with a week-long lock. The token docs add a buyback-and-burn paid for out of GAMMA revenue.

Both schemes depend on GAMMA earning fees and on the GooseFX app working, and the app is offline. Our token data at the end of October showed no measurable GOFX liquidity and only a few trades a day. Price and supply are on the GOFX token page.

Is GooseFX safe?

The validator and the DeFi products carry quite different risks.

Staking with the GooseFX validator is ordinary native staking. Your SOL stays in a stake account you control, and the validator never holds it. Solana has no slashing, so a poorly run validator can cost you rewards but cannot touch your staked SOL.

The bigger question is whether the operator keeps going. At 0%, GooseFX keeps none of its stakers' inflation rewards or MEV tips. It must still pay the Validator Admission Ticket, about 0.8 SOL each epoch, to stay in the voting set. If that fee goes unpaid, the validator sits the epoch out and its stakers earn nothing for it. A commission rise takes about two epochs to reach payouts, so stakers who check now and then have time to move.

GAMMA and GOFX carry more risk:

• The audit covers the original GAMMA program only. Offside Labs audited it in November 2024. GooseFX says the audit found one critical and five medium issues, all fixed. We found no audit of GAMMA v2 or the GOFX staking program.
• The GAMMA program (GAMMA7meSFWaBXF25oSUgmGRwaW6sCMFLmBNiMSdbHVT) is not frozen, so its code can still be changed. At its last check in September 2025, OtterSec's verifier found the deployed program did not match the public code. We could not confirm whether one wallet or a multisig holds the upgrade key. Changeable code, an unknown key holder and a quiet team add up to a material risk.
• With no app, LPs who still have funds in GAMMA may need to withdraw through the program directly or a third-party tool.
• Fusion lends pool funds to Kamino, which adds a second protocol's risks.

Who GooseFX is for

The GooseFX validator suits SOL holders who want 0% commission and will check on it from time to time. It suits people less if they want an operator with a clear way to cover its own running costs.

GAMMA is not a sensible place for new liquidity in November 2026. Its app is offline and its public code has not changed since July 2025. Anyone still holding GAMMA positions or staked GOFX should focus on getting their funds out.

GooseFX alternatives

• For trading and liquidity, Meteora offers dynamic-fee pools, Orca runs concentrated-liquidity pools, and Raydium runs both standard and concentrated pools. All three are actively built and routed by Jupiter.
• For staking SOL, any well-run validator works, or a liquid staking token if you want to keep using your SOL in DeFi. Solana Compass runs its own validator and the compassSOL token, so we compete with GooseFX here. Our validator also takes 0% of inflation rewards, but 10% of MEV tips, and compassSOL charges 2.5% of rewards. You can compare stake pools side by side.

GooseFX history

• 2021: GooseFX launches on Solana as a DeFi platform, and GOFX goes live on 2 November 2021.
• 2022: a Pyth interview from June 2022 describes single-sided liquidity pools, perpetual futures and NFT tools as its main products.
• December 2023: GooseFX deprecates the NFT aggregator. The docs later list the single-sided pools and perps as archived too.
• November 2024: Offside Labs completes its audit of GAMMA.
• July 2025: the last public change to the GAMMA code lands.
• By November 2026: the website offers validator staking only, and the GAMMA app and data addresses no longer load.
