Setup

The following setup steps will reference various Symbiotic core contracts. Refer to their deployments page and core source code.

​
Prerequisites

For technical users who’re comfortable running Foundry scripts, we’ve provided example code for every step in the setup process. → Setup Scripts
Alternatively the Symbiotic CLI can assist in many of these steps. Refer to their docs.
Docs: Tooling:
  • git clone - Git — install
  • forge script, cast - Foundry — install
  • python3 symb.py - Symbiotic CLI — install

​
Vault Configuration

The Vault configuration process consists of the following substeps:
1

Deploy Burner Router

The Burner Router defines where slashed collateral is sent (burn address, treasury, etc.).
Every Vault must point to a Burner Router, so we deploy this first.For the official Symbiotic approach, see: Symbiotic Burner Router Deployment Guide

Deploy Vault Delegator + Slasher

A Vault is the core Symbiotic primitive—an ERC-20 pool that can be restaked across networks and operators.
We use NetworkRestakeDelegator (type 0) for Ditto.
The Veto Slasher lets a resolver veto or approve each slash event.For the official Symbiotic approach, see: Symbiotic Core Modules Deployment Guide

Deploy Default Staker Rewards

DefaultStakerRewards harvests rewards earned by the Vault and redistributes them to depositors, taking an optional admin fee. For the official Symbiotic approach, see: Symbiotic Staker Rewards Deployment Guide 
# Define parameters
VAULT=<vault address from previous step>

  --chain sepolia \
  --private-key <your-private-key> \
  --etherscan-api-key <etherscan api key> \
  --broadcast

​
Deposit Collateral

After the vault, burner router, delegator, and slasher are deployed in the previous step, the vault must obtain deposits of the appropriate ERC20 collateral type. These deposits can come from a variety of sources depending on the vault. For the official Symbiotic approach, refer to the Symbiotic CLI Guide
Before depositing, ensure you have approved the vault to spend your tokens:
# Approve tokens using cast (replace with your addresses)
cast send <COLLATERAL_TOKEN> "approve(address,uint256)" <VAULT_ADDRESS> <AMOUNT> \
  --rpc-url <your-rpc-url> \
  --private-key <your-private-key>

​
Vault Actions

Finally, the vault curator address must make some calls to allocate collateral to the Ditto network and operators.
For Ditto, the subnetwork ID is always 0. The subnetwork bytes32 value is computed by concatenating the network address with the subnetwork ID.For Mainnet, the subnetwork bytes32 value is:
0x8560C667Ae72F28D09465B342A480daB28821f6b000000000000000000000000
For Sepolia:
0x683Ed12e213a6D78C338D4e18440C42bb936085A000000000000000000000000
1

Set Network Limit

First, call setNetworkLimit(bytes32 subnetwork, uint256 amount) on the delegator module of the vault. This sets the total amount of collateral the vault would like to restake to the Ditto network.
# Using cast (replace with your addresses and values)
DELEGATOR=<delegator address>  # The delegator module of your vault
SUBNETWORK=0x8560C667Ae72F28D09465B342A480daB28821f6b000000000000000000000000  # For mainnet
LIMIT=<amount>  # Amount in wei (e.g., 1000000000000000000000 for 1000 tokens)

cast send $DELEGATOR "setNetworkLimit(bytes32,uint256)" $SUBNETWORK $LIMIT \
  --rpc-url https://ethereum-rpc.publicnode.com \
  --private-key <your-private-key>
2

Set Operator Network Shares (for NetworkRestakeDelegator)

NetworkRestakeDelegator (type 0)You must also call setOperatorNetworkShares(subnetwork, operator, shares) to allocate stake to specific operators.
OperatorSpecificDelegator (type 2)This step is not required as 100% of shares are automatically allocated to the single operator.
# Using cast (replace with your addresses and values)
DELEGATOR=<delegator address>  # The delegator module of your vault
SUBNETWORK=0x8560C667Ae72F28D09465B342A480daB28821f6b000000000000000000000000  # For mainnet
OPERATOR=<operator address>  # Your operator address
SHARES=<shares>  # Amount in basis points (e.g., 10000 for 100%)

cast send $DELEGATOR "setOperatorNetworkShares(bytes32,address,uint256)" $SUBNETWORK $OPERATOR $SHARES \
  --rpc-url https://ethereum-rpc.publicnode.com \
  --private-key <your-private-key>
Here is an example of how the vault curator would complete this step using a Foundry script:
// SaveToFile: VaultActions.s.sol
// SPDX-License-Identifier: MIT
pragma solidity 0.8.19;

import {Script} from "forge-std/Script.sol";
import {console2} from "forge-std/console2.sol";
import {IOperatorSpecificDelegator} from "symbiotic-core/src/interfaces/delegator/IOperatorSpecificDelegator.sol";

contract VaultActions is Script {
  function run() external {
    vm.startBroadcast();

    // Replace with your delegator address
    IOperatorSpecificDelegator delegator = IOperatorSpecificDelegator(0x75b131De299A5D343b9408081DD6A9891b8c);
    
    // Set network limit (1,000,000 tokens with 18 decimals)
    delegator.setNetworkLimit(0x8560C667Ae72F28D09465B342A480daB28821f6b000000000000000000000000, 1000000 ether);

    // Check stake allocation for the operator
    uint256 stake = delegator.stake(0x8560C667Ae72F28D09465B342A480daB28821f6b000000000000000000000000, msg.sender);
    console2.log("Stake toward operator:", stake);

    vm.stopBroadcast();
  }
}
To run this script:
# Create the script file and paste the content above

# Execute the script
forge script VaultActions.s.sol:VaultActions \
  --rpc-url https://ethereum-rpc.publicnode.com \
  --private-key <your-private-key> \
  --etherscan-api-key <etherscan api key> \
  --broadcast
