OlympusGovDelegation.sol

OlympusGovDelegation implements DLGTE, handling the actual mechanics of delegation. It creates and manages escrow contracts for delegates through the DelegateEscrowFactory, and tracks how much gOHM each policy has deposited for each user.

Core State

struct AccountState {
    EnumerableSet.AddressSet delegateAddresses;  // Set of current delegates
    uint112 totalGOhm;                          // Total gOHM across all policies
    uint112 delegatedGOhm;                      // Amount currently delegated
    uint32 maxDelegateAddresses;                // Max delegates allowed (default 10)
}

// Track gOHM deposited per policy per account
mapping(address policy => mapping(address account => uint256 amount)) _policyAccountBalances;

// Track each account's delegate info
mapping(address account => AccountState) _accountState;

Functions

Deposits and Withdrawals

depositUndelegatedGohm()

• Pulls gOHM from policy and tracks for user

• Updates total in AccountState and policy balance

• gOHM stays in module until delegated

withdrawUndelegatedGohm()

• Returns gOHM to policy if enough undelegated balance

• Checks both policy's deposited amount and user's undelegated amount

• Updates both AccountState and policy balance

Delegation Management

applyDelegations()

• Processes array of delegation requests

• For each request:

  • If amount positive: creates/updates escrow and delegates

  • If amount negative: pulls from escrow and undelegates

• Requires amount <= undelegated balance for delegations

• Tracks delegate addresses in AccountState

• Enforces max delegate limit

setMaxDelegateAddresses()

• Updates max delegate limit for an account

• If set to 0, defaults to DEFAULT_MAX_DELEGATE_ADDRESSES

Internal Functions

_applyDelegation()

• Handles single delegation request

• Creates escrow through factory if needed

• Moves gOHM to/from escrow

• Updates delegate address tracking

_applyDelegations()

• Batch processes multiple requests

• Tracks running totals of amounts delegated/undelegated

_getOrCreateDelegateEscrow()

• Gets existing escrow or creates new through factory

• Updates delegate address set

• Checks against max delegate limit
