}Expand description
The conversion metadata registered on the bridge for a single faucet.
Encapsulates the origin-chain identity and bridge-side policy of a faucet: the EVM token address, network id, decimal scale, whether the faucet is Miden-native (lock/unlock) or bridge-owned (burn/mint), and the keccak256 metadata hash.
Fields§
§faucet_account_id: AccountIdAccount ID of the faucet being registered.
origin_token_address: EthAddressOrigin EVM token address the faucet wraps.
scale: u8Decimal scaling factor between the origin-chain unit and the Miden-side unit (e.g. 0 for USDC, 8 for ETH).
origin_network: u32Origin network / chain ID the token lives on.
is_native: booltrue for Miden-native faucets (bridge-in unlocks from the bridge vault, bridge-out
locks into it); false for bridge-owned faucets (bridge-in mints via the faucet,
bridge-out burns via the faucet).
metadata_hash: MetadataHashkeccak256 hash of the ABI-encoded token metadata (name, symbol, decimals).
Implementations§
Source§impl ConversionMetadata
impl ConversionMetadata
Sourcepub fn to_elements(&self) -> Vec<Felt>
pub fn to_elements(&self) -> Vec<Felt>
Serializes the metadata to the 18-felt layout consumed by CONFIG_AGG_BRIDGE.
origin_network is written in raw u32 form (no byte swap). The bridge stores it as-is
in faucet_metadata_map; bridge_out::convert_asset later applies swap_u32_bytes to
produce the leaf-side representation. The token-registry side of registration applies
the matching swap inside register_faucet’s MASM before hashing, keeping the hash
byte-identical with the leaf-side lookup_faucet_by_token_address input.
