Example Implementation

This is a short example implementation of a teleportation script that teleports 1 DAI from Arbitrum One to Ethereum Mainnet.
For more examples, check out the demo repository.

import { TeleportBridge } from 'teleport-sdk'
// assume getSigner returns a ethers.js Signer
import getSigner from 'src/getMetamaskSigner'

// get a hold of a signer
const signer = getSigner()

// initialize a bridge object
const bridge = new TeleportBridge({
    srcDomain: 'arbitrum',
})

// get fees to be paid for teleporting 1 DAI
const amounts = await bridge.getAmounts(
    ethers.constants.WeiPerEther()
)

// start teleporting 1 DAI
const bridgeCall = await bridge.initTeleport({
    sender: signer,
    receiverAddress: signer.address,
    amount: ethers.constants.WeiPerEther(),
})

// recover the TeleportGUID from our sent transaction
const guid = await bridge.getTeleportGUIDFromTxHash(
    call.tx.hash
)

// collect attestations from the Maker Oracle network
const attestations = await bridge.getAttestations(
    call.tx.hash
)

// send the GUID and attestations to a relayer and wait until the transaction has been posted
await bridge.relayMintWithOracles(
    receiver: signer.address,
    teleportGUID: guid,
    signatures: attestations,
    relayFee: amounts.relayFee
)
