SoSoValue wallet

What is SoSoValue (SOSO)?

SOSO is the native token of SoSoValue, a crypto research platform that pairs an AI-driven market data and news feed with an on-chain index product called the SSI protocol. The SSI side packages baskets of tokens (sector indexes such as a large-cap or DeFi basket) into single ERC-20 index tokens that can be minted and redeemed against the underlying assets. SOSO itself is not one of those index tokens. It is the platform token: it is used for governance within the SoSoValue ecosystem, for staking to participate in the platform's programs, and for fee discounts on the SSI protocol when staked.

What matters for holding it: SOSO is a plain ERC-20 with a fixed balance. There is no rebase, no interest accrual and no token account to open. Because it exists both on Ethereum and on Base, the same holder address receives SOSO on either chain, but the two balances are independent. A transfer out on Ethereum is paid in ETH on Ethereum; a transfer out on Base is paid in ETH held on Base, which is a separate balance again. Before sending SOSO to an exchange or another wallet, make sure the receiving side accepts it on the chain you are sending from, since the address alone does not tell you which network the recipient expects. The ticker is short and generic, so also check that any token you are adding is the SoSoValue contract rather than an unrelated token with the same four letters.

Supported networks in Tangem (2): Base, Ethereum.

The Tangem app shows the network and the address on the send screen, and the holder checks them before the card signs by NFC tap. For a token that lives in two identical-looking copies, having the network shown at the moment of sending is the reason a Tangem card suits SOSO well.
