Liquid Staking (Liquid Delegation Vaults)
Liquid staking on Tangle lets stakers keep a transferable position while their assets secure operator-run services. It is implemented as ERC-7540 liquid delegation vaults that wrap the standard staking flow in MultiAssetDelegation.
Each vault is tied to one operator, one asset, and one blueprint selection mode. Deposits are immediate, while redemptions are asynchronous and follow protocol exit delays.
Who This Is For
- Stakers who want liquidity without exiting their staking position.
- Integrators who want a tokenized staking position per operator and asset.
- Operators who want a clean vault surface for delegators.
What Changes vs Direct Staking
- Liquid shares: you hold ERC20 shares instead of a static delegation record.
- Fixed configuration: operator + asset + blueprint selection is fixed per vault.
- Async exits: redemptions use the protocol’s unstake delays.
Liquid delegation vaults wrap protocol staking with transferable shares and asynchronous exits.
Rewards and Accounting
Liquid delegation vaults manage delegation and redemption. Incentives and service-fee accounting are still tracked by the protocol. Because the vault is the delegator on-chain, accruals are attributed to the vault address.
Reward claim surfaces live in the protocol:
- Service fees are claimed through
ServiceFeeDistributor.sol. - TNT incentives are claimed through
RewardVaults.sol.
The vault does not automatically distribute those rewards to share holders; integrators need to wire a distribution path if they want reward pass-through.
