pub struct AggLayerFaucet { /* private fields */ }Expand description
An AccountComponent implementing the AggLayer Faucet.
It re-exports mint_and_send and receive_and_burn from the agglayer faucet library.
Conversion metadata (origin address, origin network, scale, metadata hash) is held by the
bridge, not the faucet — see
AggLayerBridge and the faucet_metadata_map populated on registration.
§Storage Layout
- All
FungibleFaucetstorage slots (token config + name + mutability + description + logo URI + external link). Conversion metadata is no longer stored on the faucet; the bridge holds it infaucet_metadata_map.
§Required Companion Components
This component re-exports fungible::mint_and_send, which requires:
Ownable2Step: Provides ownership data (bridge account ID as owner).miden_standards::account::policies::TokenPolicyManager: Provides mint and burn policy management.
These must be added as separate components when building the faucet account.
Implementations§
Source§impl AggLayerFaucet
impl AggLayerFaucet
Sourcepub fn new(
symbol: TokenSymbol,
decimals: u8,
max_supply: Felt,
token_supply: Felt,
) -> Result<AggLayerFaucet, FungibleFaucetError>
pub fn new( symbol: TokenSymbol, decimals: u8, max_supply: Felt, token_supply: Felt, ) -> Result<AggLayerFaucet, FungibleFaucetError>
Creates a new AggLayer faucet component from the given configuration.
The faucet’s display name is derived from the symbol (an AggLayer faucet is identified by its symbol; the human-readable name is not used in the bridge protocol).
§Errors
Returns an error if:
- The decimals parameter exceeds maximum value of
FungibleFaucet::MAX_DECIMALS. - The max supply exceeds maximum possible amount for a fungible asset.
- The token supply exceeds the max supply.
Sourcepub fn with_token_supply(
self,
token_supply: Felt,
) -> Result<AggLayerFaucet, FungibleFaucetError>
pub fn with_token_supply( self, token_supply: Felt, ) -> Result<AggLayerFaucet, FungibleFaucetError>
Sets the token supply for an existing faucet (e.g. for testing scenarios).
§Errors
Returns an error if the token supply exceeds the max supply.
Sourcepub fn token_config_slot() -> &'static StorageSlotName
pub fn token_config_slot() -> &'static StorageSlotName
Storage slot name for the token config word
[token_supply, max_supply, decimals, token_symbol].
Sourcepub fn owner_config_slot() -> &'static StorageSlotName
pub fn owner_config_slot() -> &'static StorageSlotName
Storage slot name for the owner account ID (bridge), provided by the
Ownable2Step companion component.
Sourcepub fn allowed_notes() -> BTreeSet<NoteScriptRoot>
pub fn allowed_notes() -> BTreeSet<NoteScriptRoot>
Returns the set of input-note script roots that AggLayer faucet accounts accept.
The faucet’s AuthNetworkAccount component is initialized with this allowlist so only
MINT and BURN notes can drive the faucet.
Sourcepub fn try_faucet_from_account(
faucet_account: &Account,
) -> Result<FungibleFaucet, AgglayerFaucetError>
pub fn try_faucet_from_account( faucet_account: &Account, ) -> Result<FungibleFaucet, AgglayerFaucetError>
Extracts the underlying FungibleFaucet component (which holds the token metadata)
from the storage slots of the provided account.
§Errors
Returns an error if:
- the provided account is not an
AggLayerFaucetaccount.
Sourcepub fn owner_account_id(
faucet_account: &Account,
) -> Result<AccountId, AgglayerFaucetError>
pub fn owner_account_id( faucet_account: &Account, ) -> Result<AccountId, AgglayerFaucetError>
Extracts the bridge account ID from the Ownable2Step owner config storage slot
of the provided account.
§Errors
Returns an error if:
- the provided account is not an
AggLayerFaucetaccount.
