Bybit Staked SOL

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

bbSOL is a Solana stake-pool receipt co-branded by Bybit and deployed and operated through Sanctum. DefiLlama recorded about $91.9M on 2026-08-14. The inherited exchange-IOU basis was wrong: Bybit’s own current terms say Sanctum issues the token, the stake-pool contract records deposits, and holders redeem at the bbSOL/SOL rate. bbSOL is instead a legitimate single-validator LST that did not beat selected Marinade on validator distribution and liquidity. This is category non-selection, not a freeze-risk allegation against Bybit.

Kill criteria: the events that revoke this verdict
• The selected provider in this category fails a kill criterion (these are the bench)
• bbSOL materially improves validator distribution and stressed exit liquidity relative to the selected provider

The research file

Mechanism

SOL deposited to the bbSOL stake pool mints bbSOL at the pool exchange rate. Staking rewards increase SOL represented by each token. Sanctum identifies bbSOL as running on its SPL stake-pool deployment and the launch material says stake is delegated to Bybit’s validator; the architecture could support a broader set later, but current evidence does not establish that diversification.

Control and operating record

Sanctum hosts and manages the pool and controls its upgradeable stake-pool program through a multisig; Bybit supplies the brand and validator relationship. Current Bybit terms expressly allocate smart-contract, provider, slashing and liquidity risk to users. The product launched in August 2024. This file records published architecture and terms but does not infer a complete independent incident review.

Exit consequences

A holder may redeem through the stake-pool path subject to Solana unbonding, or seek immediate liquidity through Sanctum Router, Infinity, Reserve or secondary markets. Instant liquidity is finite and Reserve fees rise with utilization, so stressed sale can occur below the protocol exchange value. Bybit states it does not backstop bbSOL liquidity.

Why the class rule decides

This is not a custodial exchange wrapper; it belongs with Solana LST substitutes. It remains unselected because a single branded validator is less distributed than Marinade’s delegation model and current scale is smaller. Review reopens if the selected provider fails a kill criterion or bbSOL demonstrates a materially broader validator set and stronger stressed liquidity.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
