View Facet
The Account Layer View Facet provides read-only functions for querying sub-accounts, virtual accounts, affiliates, roles, legacy accounts, and system state within the Account Layer diamond. All functions are view and do not modify state.
Sub-Account Queries
getSubAccount(address account)
Sub-account address
Full SubAccountDetail struct
getUserSubAccountsAddresses(address owner, uint256 offset, uint256 limit)
Owner, pagination
Paginated array of sub-account addresses
getUserSubAccounts(address owner, uint256 offset, uint256 limit)
Owner, pagination
Paginated array of SubAccountDetail structs
getSubAccountsCountOfUser(address owner)
Owner address
Total sub-account count
The SubAccountDetail struct includes: account address, owner, name, existence flag, singleVAMode, affiliate, Symmio core, metadata, and isolation type.
Virtual Account Queries
getVirtualAccount(address account)
Virtual account address
Full VirtualAccountDetail struct
getVirtualAccountsAddressesOfSubAccount(address subAccount, uint256 offset, uint256 limit)
Sub-account, pagination
Paginated virtual account addresses
getVirtualAccountsOfSubAccount(address subAccount, uint256 offset, uint256 limit)
Sub-account, pagination
Paginated VirtualAccountDetail structs
getVirtualAccountQuoteIds(address account, uint256 offset, uint256 limit)
Virtual account, pagination
Paginated quote IDs tracked by the virtual account
getVirtualAccountsCountOfSubAccount(address subAccount)
Sub-account address
Count of active virtual accounts
The VirtualAccountDetail struct includes: account address, parent account, symbol ID, metadata, existence flag, and isolation type.
Single VA Mode & Address Prediction
getActiveVAByKey(address subAccount, VirtualAccountIsolationType isolationType, uint256 symbolId)
Sub-account, isolation type, symbol
Active virtual account address for this key (or address(0))
getSubAccountVirtualNonce(address subAccount)
Sub-account address
Current nonce (next VA uses nonce + 1)
predictNextVirtualAccountAddress(address subAccount, VirtualAccountIsolationType isolationType, uint256 symbolId)
Sub-account, isolation type, symbol
Predicted next virtual account address
The prediction function checks the reuse pool first, then singleVAMode, then generates from the next nonce — matching the exact logic used by _getOrCreateVirtualAccount in the CoreFacet. This is useful for pre-funding virtual accounts via addMarginToNextVA.
AccountManager & Signer
generateAccountManagerAddress(address registrant, string name)
Registrant, affiliate name
Deterministic AccountManager address
getSigner()
—
Current effective signer (globalSigner if set, otherwise msg.sender)
getRelatedCore(address account)
Account address
Symmio core diamond address for this account
ownerOf(address account)
Account address
Owner address (resolves sub-accounts, virtual accounts, and legacy accounts)
globalNonce()
—
Current global nonce for sub-account address generation
accountManagerImplementation()
—
Current AccountManager proxy bytecode
Affiliate Queries
getAffiliateState(address affiliate)
Affiliate address
AffiliateState (NONE, PENDING, ACTIVE, PAUSED)
getAffiliateAdmin(address affiliate)
Affiliate address
Admin address
getAffiliateFeeDistributor(address affiliate)
Affiliate address
Deterministic fee distributor address
getAffiliateSymmioCores(address affiliate)
Affiliate address
Array of registered Symmio core addresses
getAffiliateStakeholders(address affiliate)
Affiliate address
Array of Stakeholder structs (receiver + share)
getAffiliateSymmioShare(address affiliate)
Affiliate address
Symmio protocol share (fraction of 1e18)
isWhitelistedSymmioCore(address core)
Core address
Whether the core is whitelisted
getHook(address affiliate, bytes4 selector)
Affiliate, selector
Hook contract address
isOperator(address affiliate, bytes4 selector, address operator)
Affiliate, selector, operator
Whether the operator is authorized
symmioFeeReceiver()
—
Address receiving Symmio's share of fees
dryClaimAllFees(address affiliate, address symmio)
Affiliate, Symmio core
Simulated fee distribution (stakeholder addresses + amounts)
Legacy Account Queries
isLegacyMultiAccount(address account)
Address
Whether it is a registered legacy MultiAccount contract
getLegacyMultiAccounts()
—
All registered legacy MultiAccount addresses
getLegacyAccountsOfUser(address owner, uint256 maxResults)
Owner, max results
LegacyAccountInfo[] with import status, plus hasMore flag
The LegacyAccountInfo struct includes: account address, name, legacy contract address, and alreadyImported flag indicating whether the account has been imported into the Account Layer.
Role & Pause Queries
hasRole(address user, bytes32 role)
User, role
Whether the user has the role
isRoleAdmin(address user, bytes32 role)
User, role
Whether the user is a role admin
paused()
—
Whether the Account Layer diamond is paused
Constants
MAX_NAME_LENGTH()
Maximum allowed length for account and affiliate names (in bytes)
