Twinstake Joins Jupiter’s jupSOL Validator Set
Singapore, Singapore, October 27th, 2026, Chainwire
Twinstake, an institutional validator infrastructure provider, today announced an agreement relating to Jupiter’s jupSOL Pool, under which its Solana validator joins the jupSOL validator set. The integration enables institutional clients who independently choose to hold jupSOL to designate Twinstake as the validator operator for SOL attributable to their positions, subject to the pool’s designation and routing process.
The collaboration brings Twinstake’s validator infrastructure into Jupiter’s liquid staking ecosystem, allowing institutions to use an existing infrastructure provider for their jupSOL positions. The agreement means Twinstake clients that independently choose jupSOL can have SOL attributable to their positions delegated to a validator operator they already work with.
“As institutions look at DeFi, the infrastructure underneath still has to meet their standards,” said Harriet Browning, vice president of commercial at Twinstake. “Joining the jupSOL validator set means clients who independently choose jupSOL can have the related SOL delegated to an operator they already work with.”
Jupiter is a decentralized finance platform on Solana, powering swaps, perpetuals, lending, and other onchain financial activities. Its jupSOL liquid staking token allows holders to maintain transferable positions while the underlying SOL remains delegated to validators securing the network.
Under the agreement, where a Twinstake client independently chooses jupSOL and designates Twinstake, SOL attributable to its jupSOL position can be delegated to Twinstake’s validator, subject to the pool’s designation and routing process. Twinstake operates non-custodial validator infrastructure, meaning it does not take custody of delegated SOL, and a SOC 2 Type II report covers its operational controls.
The integration builds on Twinstake’s existing validator operations across major proof-of-stake networks, including Ethereum and Solana. The company serves asset managers, exchange-traded product issuers, custodians and exchanges, and operates validator infrastructure behind the first North American Solana staking ETFs.
“Institutional capital doesn’t arrive onchain all at once. It shows up through providers those teams already trust, one piece of infrastructure at a time,” said Kash Dhanda, chief operating officer at Jupiter. “Twinstake joining the jupSOL validator set is one of those pieces.”
The collaboration extends Twinstake’s institutional validator services to Jupiter’s liquid staking ecosystem as institutions evaluate opportunities across Solana. Twinstake’s role remains limited to validator operations and related technical services, and the company does not issue, distribute, custody, or arrange the acquisition of jupSOL. Decisions to acquire or hold the token remain the independent responsibility of each client.
