Stake SOL and receive obSOL, a liquid token you can hold or redeem at any time. Your position stays out of view.
Confidential by design
On a public chain every stake position is visible to anyone. Oblio pools them, earns the full provisioned rate, targets more on top, and keeps your position out of view.
Why Oblio
Private balances, exits that tell you the price up front, and a program that is tested against its own accounting. Each one is explained in an article.
obSOL is a Token-2022 mint with confidential transfers enabled from day one. Balances and amounts can be encrypted, with an optional auditor key for oversight.
Exit instantly from a reserve at a fee you see up front, or wait one epoch in a fee-free first-in-first-out queue. Both are enforced by the program.
Timelocked governance, a guardian that can only stop things, and a fuzzer that checks solvency and price monotonicity after every instruction.

Our Colosseum pitch in article form: why Solana needs a private on-chain layer, why we start with a confidential liquid staking token, what is already built and tested, and where the ecosystem goes next.
Pitch
Shares, vesting, the virtual offset and the display multiplier: why your obSOL balance stays constant while each token is worth more SOL, and why nobody can sneak in just before rewards.
Technical
Instant exits draw on a reserve and pay a fee that rises as the reserve empties. Standard exits wait in a FIFO queue and pay nothing. Here is how both are accounted for.
