NEAR

ETH <> NEAR Rainbow Bridge

Seamlessly migrate assets to NEAR’s developer-friendly and low-cost platform, without compromising on speed.

Innovation across DeFi and NFTs has increased demand on the Ethereum network and sent fees soaring.

The ETH <> NEAR Rainbow Bridge allows users to seamlessly migrate assets to NEAR’s developer-friendly and low-cost platform.

Ethereum users can easily onboard to NEAR using the ETH Faucet, hosted by Paras, and MetaMask. Simply by logging into MetaMask and proving that their account has a balance higher than 0.05 ETH, anyone can claim a NEAR account and start using the Rainbow Bridge right away.

The biggest tokens from Ethereum are now on NEAR

The first phase of the ETH ↔ NEAR Rainbow Bridge opens the gates for assets to flow freely between NEAR and Ethereum blockchains while enabling users to bridge any ERC-20 token they wish.

The following popular tokens with common ERC-20 functionality are interoperable with NEAR, including but not limited to:

  • Stablecoins like USDT (Tether), DAI, and TUSD
  • Wrapped assets like WBTC and WETH
  • DEX tokens like UNI and 1INCH
  • Lending tokens like AAVE and COMP
  • Service company tokens like HT (Huobi) and CRO (Crypto.com)

Users can send these ERC-20 assets directly from MetaMask or other Web3 wallets to NEAR wallets and apps, and vice versa.

Mobile-friendly Rainbow Bridge from Ethereum to NEAR

Inside the Rainbow Bridge

The ETH ↔ NEAR Rainbow Bridge is a trustless, permissionless protocol for connecting blockchains. The bridge protocol removes the need to trust anyone except the security of the connected chains. Anyone can deploy a new bridge, use an existing bridge, or join the maintenance of an existing bridge without getting approval from anyone else.

The Rainbow Bridge allows any information that is cryptographically provable on NEAR to be usable in Ethereum contracts and vice versa — including the ability to read the state and schedule calls with callbacks on the other chain. This means a user can vote with their ETH balance in a NEAR DAO without sending a transaction on Ethereum.

The nature of the Rainbow Bridge means its fully decentralized and adaptable to any future protocol changes. For more details about the architecture of the Rainbow Bridge, read the technical deep dive here.

How the permissionless, trustless Bridge from Ethereum works

How the Rainbow Bridge works

The bridge is accessible and easy to use. All you need is the ETH Faucet and a MetaMask wallet.

  • Once on NEAR, transactions will confirm in 1-2 seconds and cost well under $1 in most cases.
  • Since the Bridge requires transactions on Ethereum for NEAR <> Ethereum, the following costs are expected.
  • Sending assets from Ethereum to NEAR takes about six minutes (20 blocks) and for ERC-20 costs about $10 on average.
  • Sending assets from NEAR back to Ethereum currently takes a maximum of sixteen hours (due to Ethereum finality times) and costs around $60 (due to ETH gas costs and at current ETH price). These costs and speeds will improve in the near future.
