Binance Staked SOL

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

Binance Staked SOL is BNSOL, a token Binance issues to customers who stake SOL through the exchange. It held about $782M at the 2026-08-14 survey. The token is an exchange IOU that can move on Solana, but Binance’s January 2026 product terms say customer SOL is not segregated, Binance controls staking and voting decisions, fees can change at its discretion, and redemption is limited by a Binance redemption pool and per-user quota. Those are issuer claims, not incidental implementation details. This is an application of the cex-wrapped-staking rule, not an individual solvency approval or rejection of Binance.

Kill criteria: the events that revoke this verdict
• The claim becomes redeemable on-chain without the exchange’s discretion

The research file

The mechanism

A user provides SOL to Binance and receives BNSOL at a conversion rate updated each Solana epoch. On-chain staking rewards, less Binance’s staking fee, increase the SOL represented by each BNSOL rather than its token count. BNSOL is transferable, but the underlying validator operations and accounting remain a Binance service governed by Binance product terms.

Control and operating record

The controlling document is unusually direct: staked assets may be commingled with assets of Binance entities and affiliates; Binance may stake all or part, act as validator and delegate attached voting rights; it retains on-chain rewards and credits the contractual staking reward after its fee. Binance can change that fee, quotas and service availability. We did not perform a Binance balance-sheet or reserve audit for this class memo, so it must not be read as a solvency conclusion.

The exit

The terms make BNSOL-to-SOL conversion subject to both the available Redemption Pool and a Daily Redemption Quota. Binance says processing is generally about four calendar days but may be delayed by volatility, outages, validator failure or simultaneous redemptions; rewards stop when redemption is requested. A secondary-market sale may be faster, but its price can discount those issuer and liquidity constraints.

Why the class rule decides

The cex-wrapped-staking rule excludes positions where enforceability and redemption run through an exchange’s terms and operational discretion rather than a holder-controlled on-chain claim on the stake pool. BNSOL fits the rule on Binance’s own language. Review would reopen if the claim became independently verifiable and redeemable on-chain without issuer quotas or discretion.

Sources

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

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.
