Symbiosis x Symbiotic: restaking & PoS staking explained
Confused about how restaking and PoS staking actually differ? We break down what the Symbiotic vault means for SIS holders, validator security, and the rewards you can earn soon.

Key takeaways
Symbiosis partners with Symbiotic, a permissionless restaking protocol, to boost validator security and rewards.
Restaking lets you reuse staked assets as collateral across networks, much like borrowing against a deposit certificate.
Symbiosis validators can register as Symbiotic operators, earning extra rewards and stronger credibility in both networks.
Symbiotic vault stakers back these validators, adding locked collateral and improving network decentralization.
PoS Staking for $SIS is in final testing, and this integration is a step toward the Symbiosis v3 upgrade.

What is Symbiotic restaking
We have an update to share today.
Here’s what’s coming:
Symbiosis Validators will be able to enhance their stakes, earning additional rewards and gaining more influence.
The Symbiosis protocol will see improved security, decentralization, and ecosystem growth.
A wave of new validators is set to join the network.
How are we making this happen?
It’s to do with a partnership with Symbiotic, a leading restaking protocol.
And yes, this is closely tied to upcoming Symbiosis PoS Staking launch – just as you might have guessed!
What is Symbiotic
Symbiotic is a permissionless restaking protocol.
Imagine you deposit your money in a bank, receiving a certificate of deposit (CD) that earns interest over time. This CD represents your initial investment and the accruing interest.
Symbiotic allows you to essentially use that ‘CD’ as collateral to secure additional financial opportunities, similar to using it to back a loan or invest in another venture.
In the blockchain context, this means you can take your staked assets (represented by tokens) and "restake" them across multiple networks or protocols.
How it works:
Users deposit various ERC-20 tokens, including staked assets and liquidity positions, into Symbiotic's system.
These deposits are managed in specialized vaults that handle delegation strategies and distribute rewards.
Operators, responsible for running the infrastructure of decentralized networks, receive delegated stakes from these vaults to perform network operations.
But why is this system of interest to us?
Shift towards Symbiosis PoS staking
The introduction of PoS Staking in the Symbiosis protocol has sat on our roadmap for some time now, and it’s almost done.
As many of you know, this will strengthen the security of the Symbiosis protocol while allowing participants to stake $SIS tokens and earn rewards, all while contributing to the protocol’s overall resilience.
With the integration of Symbiotic, we gain an additional layer of security, increasing the locked collateral and enhancing the network’s robustness.
As we near the release of PoS Staking, we’re sharing this update.
Currently, we’re in the final stages of testing and fine-tuning, with the finish line in sight.
Let’s now explore the specific use case of integrating Symbiotic into Symbiosis.
How this integration works
Here’s a diagram that illustrates the integration between the Symbiotic Ecosystem and the Symbiosis Ecosystem.

Let’s break it down with the following ideas:
Symbiosis Validators Join Symbiotic as Operators
Symbiosis validators have the opportunity to register as operators within the Symbiotic ecosystem.
This integration allows them to participate in Symbiotic's security protocol, thereby enhancing their role and benefits within both ecosystems.
Symbiotic Vault Stakers Support Validators
Symbiotic Vault Stakers can stake their assets in support of the Symbiosis Validators who have joined as Operators.
This staking mechanic further increases the reputation of these Validators, provides them with additional rewards, and strengthens their standing within the network.
Benefits for Symbiosis
Assets staked in Symbiotic remain within the Symbiotic system but indirectly benefit the Symbiosis protocol.
For example, Symbiosis validators who participate in Symbiotic as Operators will improve their credibility within Symbiosis. Other participants are, therefore, incentivized to collaborate with them.
Moreover, Symbiotic Vaults, fueled by stakers' contributions, enhance the security, decentralization, and liquidity of the Symbiosis ecosystem.
This integration creates a feedback loop: as Validators participate in Symbiotic, they strengthen the ecosystem while earning additional rewards and enhancing their status.
What’s next?
We will soon release a series of detailed materials about this integration, focusing on product features, technical explanations, and user guidance. These resources will help clarify how the integration works and what it means for participants in both ecosystems.
This marks a step toward the broader protocol upgrade to Symbiosis v3, which will bring significant improvements to functionality and usability.
Alongside these updates, we’ll also share more information on the rollout of PoS Staking, including timelines and practical steps for users to get involved.

01
What is the Symbiosis SIS Restaking Vault?
It's a Symbiotic vault on Ethereum that accepts SIS as its single collateral token. Deposited SIS is delegated to secure the Symbiosis relayer network, and depositors earn rewards for backing those cross-chain operations.
02
How large is the vault and how much can I deposit?
The vault caps at 1,000,000 SIS. The Symbiosis Foundation seeded 250,000 SIS, leaving 750,000 SIS open for deposits from SIS holders.
03
What is Symbiotic?
Symbiotic is a permissionless restaking protocol. You deposit ERC-20 tokens (including staked assets and LP positions) into specialized vaults, which handle delegation and rewards, then delegate that collateral to operators running network infrastructure.
04
How does the vault differ from standard Symbiosis PoS staking?
In PoS staking, SIS is delegated directly to validators securing a single network. In the Symbiotic vault, SIS becomes restaking collateral that can secure the Symbiosis relayer network and, in principle, other integrated protocols — with extra slashing conditions.
05
Which chain do I need my SIS on to deposit?
Ethereum. The Symbiotic infrastructure and the SIS Restaking Vault are deployed on Ethereum, so you must hold SIS on Ethereum before depositing.
06
What rewards do I earn from depositing SIS?
Depositors earn liquidity rewards for providing staked SIS that secures the protocol, plus Symbiotic Points as additional incentives. Yields depend on the vault's network and operator reward streams.
07
Can my deposited SIS get slashed?
Yes. Symbiotic vaults include a Slashing Module that applies protocol-defined penalties for operator misbehavior, so a portion of your deposited SIS can be slashed if delegated operators break the security rules.
08
How do I withdraw my SIS from the vault?
Request a withdrawal through the Symbiotic interface under the vault's "Action" tab. The vault processes it per its exit rules, then you finalize the transaction to receive SIS back to the same Ethereum address you deposited from.
