VM Bridge Contracts

The Flow VM bridge is the account and series of smart contracts that manage how assets are safely bridged between the Cadence and EVM Flow Environments.

Network	Contract Address
Emulator	0xf8d6e0586b0a20c7
Cadence Testing Framework	0x0000000000000001

Contracts

There are many important contracts deployed to the bridge account. You should refer to the bridge repo and the bridge guides for more detailed information about the bridge and tutorials for how to use the bridge properly.

Here is a list of each Cadence contract used for the bridge:

Contract	Purpose
CrossVMNFT	Contract that defines cross-VM NFT-related interfaces.
CrossVMToken	Contract that defines cross-VM Fungible Token Vault interfaces.
FlowEVMBridgeHandlerInterfaces	Defines interface for custom bridged token handlers.
IBridgePermissions	Defines an interface to prevent bridging for a specific token.
ICrossVM	Defines an interface to get EVM contract addresses.
ICrossVMAsset	Defines an interface to represent a Cadence bridged version of an EVM asset.
IEVMBridgeNFTMinter	Defines an interface that allows the bridge to mint NFTs.
IEVMBridgeTokenMinter	Defines an interface that allows the bridge to mint FTs.
IFlowEVMNFTBridge	Defines core methods for bridging NFTs.
IFlowEVMTokenBridge	Defines core methods for bridging FTs.
FlowEVMBridge	The main entrypoint for briding tokens across Flow VMs.
FlowEVMBridgeAccessor	Defines methods to route bridge requests from the EVM contract to the Flow-EVM bridge contract.
FlowEVMBridgeConfig	Used to store configuration options for the VM Bridge.
FlowEVMBridgeCustomAssociations	Stores configuration information about custom bridged asset configurations.
FlowEVMBridgeCustomAssociationTypes	Defines interfaces used to specify custom bridged asset associations.
FlowEVMBridgeHandlers	Defines mechanisms to handle assets with custom associations (Deprecated).
FlowEVMBridgeNFTEscrow	Handles locking of NFTs that are bridged from Flow to EVM and back.
FlowEVMBridgeResolver	Defines methods to resolve Metadata Views for bridged assets.
FlowEVMBridgeTemplates	Serves Cadence code from chunked templates for bridge-deployed assets.
FlowEVMBridgeTokenEscrow	Handles locking of FTs that are bridged from Flow to EVM and back.
FlowEVMBridgeUtils	Defines many different utility methods that are used by bridge contracts.
ArrayUtils	Provides useful utility functions for array manipulation.
ScopedFTProviders	Provides utilities to create provider capabilities for tokens that are restricted to a specific amount.
Serialize	Provides utilities to serialize common types to JSON compatible strings.
SerializeMetadata	Provides methods to serialize NFT metadata as a JSON compatible string.
StringUtils	Provides useful utility functions for string manipulation.

EVM bridge Solidity contracts

There are also Solidity contracts that are deployed in Flow EVM that are needed for the bridge. Here are their addresses:

And below are the bridge escrow's EVM addresses. These addresses are [CadenceOwnedAccounts (COA)] and they are stored in the same Flow account as you'll find the Cadence contracts (see above).
