Enjin Assets Bridge

The Enjin Bridge allows you to transfer tokens between Ethereum Mainnet and Enjin JumpNet.
Using the Bridge, both Enjin Coin (ENJ) and ERC-1155 assets created using the Enjin Platform can be transferred between the Enjin JumpNet and Ethereum Mainnet networks.
The Enjin Bridge smart contract receives an asset on one network, and once claimed, replicates the asset on the corresponding bridged network.
Currently, the asset bridging functionality is only accessible through the Enjin Platform API. The user interface component, accessible within the Enjin Wallet, will be released at a later stage.
Mutations:
The Enjin Bridge has 3 mutations:
Mutation
Usage
​BridgeAsset​
Used to transfer a single asset.
​BridgeAssets​
Used to transfer multiple assets.
​BridgeClaimAsset​
Used to claim assets on the opposite network.
BridgeAsset
The BridgeAsset mutation allows you to send one single asset/NFT to the bridge contract. You can run the following mutation to get started:
mutation {
  BridgeAsset(
    assetId: "tokenId"
    assetIndex: "0000000000000001"
    value: "1"
    wallet: "walletaddress"
  ) {
    id
    blockchainData {
      encodedData
    }
  }
}
Steps & Process:
1.Call the BridgeAsset mutation.
2.Confirm the request in your wallet.
3.The asset will moved from your address to the bridge, ready to be claimed from the other side of the bridge.
Arguments:
assetId (type: String!, example: "7000000000000002")
assetIndex (optional, type: String, example: "0")
value (optional, type: BigInt, example: "5", default: "1")
Must be omitted, or "1", when asset is non-fungible.
wallet (optional, type: EthAddress, project-schema only)
BridgeAssets
The BridgeAssets mutation allows you to send multiple digital assets/non-fungible tokens (NFTs).
You can send multiple different indices using the BridgeAssets function.
The maximum number of indices that can be bridged at any given time is 100 per transaction.
mutation {
  BridgeAssets(
    assetId: "tokenId"
    assetIndices: "0000000000000001"
    value: "1"
    wallet: "walletaddress"
  ) {
    id
    blockchainData {
      encodedData
    }
  }
}
Steps & Process:
1.Call the BridgeAssets mutation.
2.Confirm the request in the wallet.
3.The assets will be moved from your address to the bridge, ready to be claimed from the other side of the bridge.
Arguments:
assetId (type: String!, example: "7000000000000002")
assetIndices (optional, type: [String!]!, example: [1, 2, 3])
wallet (optional, type: EthAddress, project-schema only)
BridgeClaimAsset
The BridgeClaimAsset mutation allows you to claim your asset/NFT on the Enjin Bridge.
This is a temporary mutation that will be natively integrated with the upcoming Enjin Wallet 2.0 release. This mutation will therefore be deprecated in the future after support has been implemented into the updated wallet.
If the asset has never been transferred to the destination network before, this mutation will have to be run twice. The first instance will create the relevant asset definition on the network and after the transaction has been mined you can call this mutation a second time to complete the transfer of the asset to the network.
mutation {
  BridgeClaimAsset(assetId: "assetid", wallet: "walletaddress") {
    id
  }
}
Steps & Process:
1.After the bridging transaction has been mined successfully, wait for approximately 20 blocks. You'll then be able to use this method to claim it on the destination network.
2.You will need to specify the assetId, and you can optionally (on the project schema) override the wallet in question.
3.Confirm the request in your wallet.
4.The bridge will fulfill the claim by sending you the exact asset initiated from the other side of the bridge.
Mutation	Usage
BridgeAsset	Used to transfer a single asset.
BridgeAssets	Used to transfer multiple assets.
BridgeClaimAsset	Used to claim assets on the opposite network.
