sTLOS Liquid Staking Review 2026: TLOS Vault on Telos EVM

sTLOS is a liquid staking protocol on Telos EVM. It accounts for all TLOS held in an ERC4626 vault that issues the sTLOS token, and it delegates that TLOS to the native rewards staking program.

It has been listed since October 2022 and shows about $276,000 in TVL, down about 5% over seven days. Two audits are listed. The protocol has no token of its own.

Telos itself is a layer-1 network that describes a fast EVM, low gas fees and a privacy layer called zkWallet. sTLOS fits into that as the staking option for people who want to keep TLOS liquid on the EVM side.

You deposit TLOS into an ERC4626 vault on Telos EVM. ERC4626 is a standard for tokenized vaults: the vault takes an asset and gives back shares that represent a claim on it. Here, the share token is sTLOS.

The vault then delegates the pooled TLOS to Telos's native rewards staking program. Staking rewards accrue to the vault, which raises the amount of TLOS each sTLOS can be redeemed for over time. This is how the usual share-based liquid staking model works, though the exact accounting is not detailed publicly.

Because sTLOS is an ordinary EVM token, you can hold it while the underlying TLOS keeps earning, instead of locking TLOS in the native staking system. Wider use of sTLOS in other apps depends on what the Telos ecosystem supports.

Fees are not published in the material reviewed. That includes any protocol fee on staking rewards and any withdrawal or unstaking charge.

Users should check the sTLOS interface for the reward rate and any fees before depositing. Gas on Telos EVM is described by the network as very low, at around $0.01 per transaction, so transaction costs are unlikely to be the main expense.

Two audits are listed for the protocol, but the auditors and findings are not detailed in the material reviewed. The team behind sTLOS and any admin or upgrade controls are also not described. Check the contract, its permissions and the audit reports before depositing.

Risks include smart-contract bugs in the vault, concentration in a single small chain, and the possibility that sTLOS trades below the value of its TLOS or has limited liquidity. With low TVL, exiting a large position through a market may be hard. This is not financial advice.

sTLOS is for existing TLOS holders on Telos EVM who want staking yield without locking tokens in native staking. It is less suited to users who need deep liquidity, multi-chain exposure or a large documented track record.
