🏦 Symbiotic Vault Types
🔷 Self-Managed Vault
The depositor controls all delegation decisions — which operators to whitelist, which networks to serve, and per-operator exposure caps. Maximum control, but requires active risk monitoring.
Best for: Sophisticated stakers who want to control their own slash exposure
🟡 Curator-Managed Vault
A named curator makes delegation decisions on behalf of depositors in exchange for a fee — similar to a Morpho Blue allocator. Curators publish their risk framework on-chain so depositors can compare before depositing.
Best for: Stakers who want hands-off restaking with professional risk management

- What is rstETH and how is it different from stETH?
- rstETH (restaked ETH) is a vault share token minted when a depositor locks collateral into a Symbiotic vault. Unlike stETH (which represents ETH deposited into Lido's validator pool), rstETH represents exposure to multiple networks simultaneously and is specific to each vault. The same depositor might hold rstETH-vault-A and rstETH-vault-B, each with different risk/reward profiles, and each slashing the underlying USDC or wstETH differently.
- How does Symbiotic's slashing oracle work compared to EigenLayer's Security Council?
- EigenLayer uses subjective slashing: when an AVS reports a fault, the Security Council votes on whether to confirm the slash before any collateral burns. Symbiotic replaces this with an immutable slashing oracle embedded in the core contracts. When a Network's on-chain rules fire a slashing signal, the oracle validates the proof, determines the slashable amount from each affected vault's delegation graph, and triggers collateral release — all without any external veto. The tradeoff is that networks must write their slashing conditions carefully, because there is no protocol-layer undo button.
- Can I restake non-ETH assets on Symbiotic?
- Yes. Any ERC-20 can serve as vault collateral, including USDC, DAI, UNI, LDO, MKR, Curve LP tokens, Uniswap V3 NFT positions, and LSTs like wstETH or rETH. A vault's collateral type is defined at deployment, and networks that want to consume security from that vault must explicitly list it in their acceptable-collateral set. This permissionless collateral model is Symbiotic's core architectural bet: by removing the asset-whitelist gate, new networks can launch with their own token as slashable collateral.
- What is the restaking flow from deposit to reward?
- The flow is: (1) depositor selects a vault, approves the ERC-20 transfer, and deposits collateral; (2) the vault mints rstETH shares proportional to the deposited amount; (3) the vault's delegation logic routes the slashable exposure to one or more operators; (4) each operator opts into networks it，愿意 serve; (5) networks distribute rewards to vaults based on the amount of delegated stake serving them; (6) the vault splits rewards between rstETH holders (via rstETH price appreciation) and the operator (via commission). All steps except operator selection are automatic on-chain logic.
- Who manages risk in Symbiotic's curator vault model?
- The curator does. In a delegated (curator-managed) vault, the curator sets the per-operator cap, the list of allowable networks, the expected reward APR, and the maximum slashable exposure. Depositors review these on-chain parameters — which are publicly readable — before depositing. Curators compete on risk framework quality: a better curator attracts more deposits because they generate higher risk-adjusted returns. Self-managed vaults shift all risk decisions to the individual depositor.
- How is restaking yield broken down?
- Symbiotic restaking yield has three components: (1) base yield — the staking return on the underlying collateral (e.g., ETH staking APY if the vault holds wstETH, or a money-market rate if it holds USDC); (2) SYM emissions — protocol-incentive tokens distributed to early vault depositors during bootstrap periods; (3) AVS rewards — network payments for security services. A concrete example: $100K in a USDC vault at 5% base, SYM emissions at 2%, and AVS payments at 3% nets roughly 10% gross before the operator's 10% fee and a 2% expected slash reserve.
