Symmetry

Symmetry (symmetry.fi, also called Symmetry Finance) is a Solana protocol for building token baskets. It has no link to Symmetry Auto Finance or other firms with the same name. Anyone can use Symmetry to create a vault that holds up to 100 tokens, each with a target weight. The vault issues its own token. Hold that one token and you own a share of the whole basket, much like a share in an index fund. Vaults keep their weights in line through on-chain auctions. The latest version, Symmetry V3, came out in March 2026 and is live on mainnet in beta. We could not find a live token for Symmetry itself.

How Symmetry V3 vaults and basket tokens work

A Symmetry vault is an on-chain account that holds a set of tokens at target weights and issues a vault token for them. When you deposit, the vault mints new vault tokens to you. When you withdraw, it burns your vault tokens and sends back your share of the underlying assets. The price of a vault token is the total value of the vault divided by the number of vault tokens in existence.

Each vault has a creator, and can have up to 10 managers with separate permissions, according to the Symmetry vault documentation. Managers can add tokens, change weights, set fees and switch automation on or off. A vault can also name a "host", which is the app or platform that lists the vault and takes a share of fees. The host and its fee are fixed when the vault is created.

Most changes to a vault go through what Symmetry calls an intent. An intent is a proposed change stored on-chain, which can carry a time delay before it takes effect. If a vault sets a delay on weight or fee changes, you can see a change coming before it applies. Two things are always immediate: a change of creator, and turning deposits on or off.

Vaults accept standard SPL tokens and Token Extensions (Token-2022) tokens. Symmetry said on 26 March 2026 that Token-2022 support lets vaults hold tokenized stocks such as xStocks AAPLx$342.26-0.7%.

Dutch auction rebalancing and keepers

Symmetry keeps a vault at its target weights by running short auctions that outside traders fill. When a token drifts too far from its target, the vault offers to sell what it has too much of and buy what it has too little of. The price starts out poor for the trader and improves over time until someone takes it. That falling-price format is called a Dutch auction.

The traders are called keepers. A keeper is a bot that watches vaults and carries out their pending tasks. Anyone can run one, and the rebalancing documentation says any wallet can call the same instructions. In a single transaction a keeper takes tokens from the vault, swaps them on a DEX such as Jupiter JUP$0.315+2.7%, and returns the proceeds. The keeper keeps any gap between the auction price and the market price, plus a bounty paid by whoever requested the work.

The auction price is tied to the oracle price and its confidence band, which is the oracle's own estimate of how uncertain the price is. Each rebalance runs three auction stages. Within a stage, the vault starts by quoting worse than the oracle price for keepers. It reaches the oracle price halfway through, then moves past it in the keeper's favour. A vault with thinly traded tokens can therefore end up paying more to rebalance.

Deposits and withdrawals use the same auction process, so they are not instant. A vault manager decides when rebalances can fire, using a drift threshold, a cooldown between rebalances and scheduled time windows. Automated rebalances also need a bounty balance to be funded for the vault.

Symmetry oracle pricing: Pyth, Raydium pools and LSTs

Symmetry gets its prices from oracles, which are services that report market prices on-chain. It supports four kinds. The first is Pyth Network PYTH$0.094+10.8% price feeds. The next two are average prices over time from Raydium RAY$1.84+1.7% pools, of either the concentrated or the constant product type. The fourth is the exchange rate of a liquid staking token (LST), read from its stake pool.

The vault creator picks the sources for each token and gives each one a weight. A token can have up to four sources.

Symmetry added Raydium concentrated pools as a source on 26 March 2026. That opened vaults to tokens that have no Pyth feed. LST pricing followed on 17 April 2026. It covers SPL stake pools and Sanctum CLOUD$0.062-1.6% pools.

Each source has an age limit. For Pyth the default is 120 seconds, per the fees and oracles documentation. As a price gets older, Symmetry treats it as less certain.

This matters to you because vault tokens are minted and redeemed at oracle prices. A token priced from one shallow pool is easier to push around than a token with a Pyth feed. Check which sources a vault uses before you deposit.

Symmetry fees: deposit, withdrawal, management and performance

Symmetry vaults can charge four fees. There is a fee when you deposit and a fee when you withdraw. There is a yearly management fee. And there is a performance fee, taken only on gains above the vault's past high. The Symmetry docs said in October 2026 that the management and performance fees were switched off for all vaults. Only the deposit and withdrawal fees were in use.

Each vault sets its own rates, so there is no single Symmetry fee. A fee can be shared between five parties: the host, the creator, the managers, the vault itself and the Symmetry protocol. The vault's share stays in the vault and helps every holder. The protocol sets a cap on each fee type.

A manager can change a vault's fees. The only brake is the time delay the vault has set, if any. Read the fee settings and the delay before you deposit.

The Symmetry homepage says the product is free for builders and traders, with custom plans for larger firms.

Symmetry CLI, SDK and what is planned before V3 leaves beta

Symmetry gives developers two tools. The first is a code library for TypeScript, @symmetry-hq/sdk. It lets an app create vaults, deposit, withdraw, rebalance and run a keeper. The second is a command-line tool on GitHub, which was at version 0.2.0 in early October 2026. It can sign with a key on your machine, or hand back unsigned transactions for another wallet to sign. It also ships with an MCP server, which is a standard way for AI agents to call tools.

On 3 October 2026 Symmetry listed three changes it is working on. It plans to cut the cost of creating a vault by up to 90%. It is rolling out the CLI "for humans and agents". And it is improving how it blends oracle prices. The team called this "the final unlock before V3 is out of beta". It gave no date.

Symmetry also said on 12 May 2026 that it was adding support for Overpass. Overpass turns deposits in Solana lending pools into tokens that earn yield. Symmetry's stated aim is to let vault managers lend out part of a vault's assets. Overpass's code sits in the same GitHub account as Symmetry's. We found no notice that this feature has shipped.

Who Symmetry is for

Symmetry suits people who want to build or hold a multi-token basket on Solana and are comfortable using beta software. That covers three main groups.

• Basket creators and fund managers who want to launch an index or a managed strategy as a single token, and earn fees on it.
• Developers and AI agent builders who want to create and manage baskets from code, through the SDK or CLI.
• Bot operators who want to run a keeper and earn bounties and auction spreads. A keeper needs SOL for transaction fees, a Jupiter API key and a reliable RPC connection, per the keeper guide.

Symmetry is a weaker fit if you want instant entry and exit, because deposits and withdrawals wait on auctions. It is also a weaker fit for passive holders who do not want to vet a vault's manager, fees and oracle sources themselves. Anyone can create a vault, so a vault's quality depends on who runs it.

Is Symmetry safe? Audits, admin control and beta risk

Symmetry V3 is beta software, and we could not find a public security audit of it. The Symmetry docs and homepage do not name an auditor or link to a report. Ask the team about this before you deposit a sum you could not afford to lose.

Symmetry does not hold your keys. Your assets sit in vault accounts run by the on-chain program. But three parties still have power over a vault, and you should know who they are.

The first is whoever controls the program. The docs give the V3 program ID as BASKT7aKd8n7ibpUbwLP3Wiyxyi3yoiXsxBk4Hpumate. On 5 October 2026 the OtterSec verified builds service showed no verified build for it. That means nobody has shown in public that the live code matches a published source. The docs list the licence as BUSL-1.1, which is not an open-source licence. We could not confirm who is able to upgrade the program.

The second is the protocol admin. One global config account sets the rules for every vault: protocol fees, fee caps, auction timings and which features are on. The docs do not say who the admin is, or whether it takes more than one signer to act.

The third is the vault's manager, who can change tokens, weights and fees. Time delays limit this only if the vault has set them.

Market risks come on top. Oracles set the price of vault tokens, so a wrong or rigged price can cost holders money. A rebalance needs keepers to show up and a bounty to pay them. We found no reports of a hack of Symmetry.

SMF token: has Symmetry launched a token?

We could not confirm that an SMF token is live. Symmetry set out plans for a token called SMF in 2021, to be used for voting and fees. CoinMarketCap still has a preview page for SMF that lists a maximum supply of 100 million. But that page shows no supply in circulation, no price and no token address. The V3 docs, the homepage and the CLI do not mention SMF at all.

So treat any Solana token with the SMF ticker as unrelated to Symmetry, unless the team confirms its address. Take the same care with airdrop claims. We found no official word of an airdrop.

The tokens Symmetry does produce are vault tokens. Each vault mints its own, with its own name and ticker. One older example is ySOL, a V2 fund made up of Solana liquid staking tokens. StakingRewards lists it as the Symmetry Solana LSD Fund.

Symmetry history: from V2 baskets to V3

Symmetry has gone through two main phases: an earlier app built around "baskets", and the V3 rebuild of 2026. The homepage says the team has been at work since 2020.

The public app for crypto indices and managed funds opened on 3 May 2023, per a press release carried by The Defiant. It used Pyth for prices and Jupiter for trades. That version ran on a program called the Symmetry Engine.

The homepage says the V2 product hosted more than 990 baskets and handled $600 million in volume over its life. The older app was still online at app.symmetry.fi when we checked in October 2026.

Symmetry announced V3 on 16 March 2026. The team called it "a complete rebuild of on-chain infrastructure for multi-token vaults on Solana". The docs for V3 describe vaults of up to 100 tokens, intents, keeper auctions and prices from more than one source. V3 runs at beta.symmetry.fi under a new program ID, apart from the V2 Symmetry Engine.
