Building Liquid Delegation Vaults

Tangle’s liquid restaking is implemented via EVM smart contracts that wrap the protocol’s restaking system into transferable vault shares.

At a high level:

  • MultiAssetDelegation tracks deposits, delegation, and undelegation.
  • LiquidDelegationVault is an ERC-7540 vault that delegates to a specific (operator, asset, blueprint selection) configuration and issues liquid shares.
  • LiquidDelegationFactory deploys vaults deterministically per configuration.

This section focuses on building or integrating with liquid delegation vaults (“bolts”) on Tangle’s EVM deployment.
