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.
NOTE: After migrating your NFTs to Arbitrum, their copies on Aurora will be burned.
Don’t worry — all your EYWA tokens contained in those NFTs will be detached and merged if bridging multiple NFTs at once. You can always check your balance in the “Dashboard”.
After the TGE, tokens will be claimable in the Claim Portal and can again be placed inside an NFT container if you so desire.
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.
* During peak hours, the Aurora network can be unstable: if you can't transfer 20 NFTs, try transferring 10 to 15 NFTs in a single transaction or try again later.
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)
