Eywa NFT Bridge from Aurora to Arbitrum

Migration from Aurora to Arbitrum

Prior to the TGE, we’ll open a bridge for transferring EYWA NFTs from the Aurora blockchain to Arbitrum. After the collection is moved to Arbitrum, the Merge function will become available.

To use the bridge and transfer your EYWA NFT from Aurora to Arbitrum, your wallet needs to have ETH in Aurora to sign the transaction and pay gwei (Ethereum accounting unit) in the Aurora chain. You can move as many as 20 NFTs* in one transaction. The transfer of one NFT costs $1 in ETH plus the cost of gas, which depends on how busy the network is at the time. The gas cost (gwei) is currently at 0.00005712 ETH for one NFT.

Example: To transfer 20 NFTs, the cost of using the bridge is $20 (i.e. 0.006369 ETH) + the network fee of 0,0007579 ETH = 0.007127 ETH or $22,37 (at the cost of ETH at the time of this writing).

There are several ways to get ETH on the Aurora chain into your wallet:

- Use the native RainbowBridge bridge (supports ETH only on the Ethereum chain)

- Swap on https://meson.fi/ (supports ETH on 11+ EVM chains)

- Swap on https://www.bungee.exchange/ (supports ETH on 10+ EVM chains)

- Swap on https://jumper.exchange/ (supports ETH and stablecoins on 10+ EVM chains)

To swap ETH from an EVM chain (Ethereum, Polygon, Arbitrum, BSC, etc.) supported by one of the above apps, you need to first load up your wallet from a CEX, DEX, or other on-ramps available to you.
