Sanctum Infinity Review: Is Its Solana LST Pool Worth It?

Sanctum Infinity is a Solana liquidity pool designed to support hundreds of liquid-staking tokens (LSTs) natively. LSTs represent staked assets and can be used in DeFi while the underlying SOL remains staked. Sanctum says Infinity enables exchanges between different LSTs, giving you a route to move between supported tokens without first exiting to SOL and staking again.

That description does not mean every LST is available at all times or that every swap will execute at the price you expect. Check the pool’s current asset list and the quote in the app before approving a transaction. The homepage also promotes SOL liquid staking and mentions a 5.49% APY, but that figure is not identified as an Infinity pool return and should not be treated as a guaranteed yield from Infinity.

Sanctum does not publish an Infinity fee schedule in the information reviewed here. Before confirming a swap, check the app for any pool fee, the quoted exchange rate and the amount you will receive. A quoted rate can differ from a simple token-price comparison because pool liquidity and the relative values of the LSTs affect what a trade returns.

You will also need SOL to pay Solana network transaction fees. Those network fees are separate from any product fee and can vary with network conditions. If you move tokens between wallets or use another service to acquire an LST, that service may have its own charges too. Do not assume that an exchange is cost-free because Sanctum describes it as frictionless. Compare the quote with the value of the tokens you are giving up, and check any exit or withdrawal conditions before putting a larger amount into the pool.

No audits are listed for Sanctum in the protocol listing. An absent listing does not prove that no review exists, but you should find current audit reports and confirm that they cover the contracts you intend to use before depositing. Sanctum’s homepage describes staking and infrastructure products, but does not specify Infinity’s custody arrangements, insurance or a licence for the pool.

Infinity also carries risks that are separate from the security of its code. LSTs can trade below the value of the SOL they represent, and different LSTs can have different validators, withdrawal processes and liquidity. A pool can help users exchange assets, but it cannot remove those underlying risks or guarantee that you can exit at a preferred rate. Treat deposits as exposed to both smart-contract risk and the risks of each token in the pool. Avoid depositing funds you may need immediately.

Infinity runs on Solana, so you need a Solana-compatible wallet and SOL for transaction fees. Sanctum does not specify wallet support, mobile support, transaction speed or a detailed Infinity onboarding process in the information reviewed here. Check the current app’s wallet options before connecting, and make sure the wallet is set to Solana rather than another network.

A wallet connection is not the same as a deposit, but transaction approvals can authorize actions involving your assets. Read each prompt, verify the token and amount, and avoid signing requests you do not understand. Before using a new pool, inspect its supported LSTs and the price quote; then consider testing with a small amount. Keep your recovery phrase private and never share it with a site, support agent or anyone claiming to help you connect.

Infinity is most relevant if you already use Solana LSTs and want to exchange among supported tokens through a multi-asset pool. Its broad LST support is the product’s main appeal. It is less suitable if you want a simple, predictable savings product, need guaranteed access to funds, or cannot tolerate a token trading below its underlying value.

Several important decision points remain unclear: Sanctum does not publish an Infinity fee schedule or detailed pool-specific custody and withdrawal information in the material reviewed here, and no audits are listed. The homepage’s general staking APY should not be confused with a return from an Infinity deposit. If those disclosures matter to your decision, wait until you can verify them directly. You should also confirm that the exact LST you want to use is supported and that the pool has enough liquidity for your intended transaction.
