SoSoValue Indexes Review 2026: On-Chain Spot Crypto Index Tokens

SoSoValue Indexes, or SSI, is a spot crypto index protocol from the SoSoValue platform. It lets users hold a single token that represents a basket of crypto assets, aiming to remove the need to pick individual tokens. The homepage describes it as secure, transparent and built fully on-chain.

DefiLlama lists it under Indexes, tracking it since January 2025, with about $101.7M in TVL and a 0.5% rise over seven days. A weekly update snippet in public reporting cites a higher $200.4M TVL and 332.0K holders for a February date, so figures vary by source and timing.

The protocol appears on Bitcoin, Ethereum, Hyperliquid, BNB Chain, XRPL, Solana, Doge and Cardano, and DefiLlama notes two audits. Public reporting also mention staking epochs and a tool for building and listing custom indexes.

A spot index protocol bundles several crypto assets into one token. Holding that token gives a share of the whole basket, and its value moves with the combined prices of the assets inside. The aim is passive exposure to a sector or theme without picking and managing individual tokens.

SSI describes itself as built fully on-chain and spot-based, which means the tokens are backed by actual assets rather than derivatives. DefiLlama shows the protocol touching eight networks, so the basket assets span several chains. The project does not detail how minting, redemption or rebalancing is carried out.

The project also lists an SSI token with staking epochs, and DefiLlama names SOSO as the protocol token. How these tokens relate to each other and to fee or reward flows is not explained, so readers should check the official documentation.

The project does not publish a fee schedule. The homepage calls the product low-cost, but mint, redemption, management and staking fees are not stated.

Users would need to check the app and the SoSoValue Indexes help centre for current fees. Network gas on the relevant chain is a separate cost in any on-chain product.

DefiLlama lists two audits, but the auditors, scope and findings are not public, so readers should look up the reports themselves. The project does not describe custody arrangements or how assets on non-EVM chains are held, which matters for any index that spans many networks.

No hack or incident appears, and the protocol has been tracked only since January 2025. Index tokens remain exposed to market risk and to smart-contract and operational risk. Check the regulatory status of crypto products where you live before using it.

It is aimed at passive crypto investors who want broad or sector exposure without picking individual tokens. It also suits users who want to build or follow custom indexes. People who need clear fee tables or want to avoid multi-chain complexity should check the documentation closely first.
