Create user / wallet

To be able to interact with the trustlines protocol a user, i.e. wallet, is needed. You therefore have to create an instance and load it into the library. The wallet manages your key pair and is used for cryptographically signing transactions, thus enabling the establishment of trustlines and transfers. Depending on the initial configuration of the TLNetwork instance, you can create either a new instance of type ethers or type identity. The former type is based on the wallet object of the ethers.js library, whereas the second type uses an identity contract to enable meta-transactions.

Create instance of type ethers

Note that a user of type ethers can not use meta-transactions. The user therefore needs some coins (TLC, Test TLC, ... ), depending on the connected relay server and blockchain, before being able to execute a transaction.

const laika = new TLNetwork({

protocol: "https",

wsProtocol: "wss",

host: "relay0.testnet.trustlines.network",

path: "/api/v1",

walletType: "ethers",

})

const newEthersUser = await laika.user.create()

await laika.user.loadFrom(newEthersUser)

Create instance of type identity

A user of type identity makes use of meta-transactions. Therefore the addresses of the deployed identity factory and implementation contracts have to be set. An additional step of deploying the identity contract of the newly created user is also necessary.

const laika = new TLNetwork({

protocol: "https",

wsProtocol: "wss",

host: "relay0.testnet.trustlines.network",

path: "/api/v1",

walletType: "identity",

identityFactoryAddress: "0x8D2720877Fa796E3C3B91BB91ad6CfcC07Ea249E",

identityImplementationAddress: "0x8BEe92893D3ec62e5B3EBBe4e536A60Fd9AFc9D7",

})

const newIdentityUser = await laika.user.create()

await laika.user.loadFrom(newIdentityUser)

// Additional step to deploy the identity contract of newly created user

const txHash = await laika.user.deployIdentity()
