Ethereum is a decentralized finance platform based on blockchain technology that provides security and safety. Transactions are made through smart contracts, which are actually the central component of this platform. Ethereum has its own cryptocurrency, ETH, and it is in 2nd place on market value right after Bitcoin.

Cosmos is an entire ecosystem of DeFi blockchains that exchange cryptos and some other data by using the IBC protocol. It’s a proof-of-stake kind of chain. The first chain of the Cosmos network is Cosmos-Hub which connects to other blockchains through an inter-blockchain communication protocol. Cosmos Hub has its primary token called ATOM, and by staking (by locking them up), users can earn rewards in the form of new ones. Still, staking isn’t risk-free.

Best Ethereum to Cosmos bridges (many still work in progress)

In the text below is a list of the best bridges between Ethereum and Cosmos blockchain bridges.

Gravity Bridge – top Cosmos Ethereum bridge

Gravity DEX protocol is the 1st cross-chain protocol on Cosmos Hub. It is secured by 3 billion USD in cryptos. It allows swaps and a pool of digital assets between Cosmos Hub-connected chains, including Ethereum. It has low fees between 0.01% and 0.1%.

Gravity is a cross-chain bridge designed specifically for the Cosmos Hub, known for its high security, efficiency, and decentralized nature. It is an advancement of Peggy, a bridge that has been in development by the Interchain Foundation and Althea for a significant part of the past year. The primary function of Gravity is to facilitate the transfer of ERC20 assets from Ethereum to a Cosmos-based chain and vice versa. Additionally, it will soon be able to transfer Cosmos assets to an ERC20 representation on Ethereum, which is expected to be available in the coming months. – second best Atom to ETH bridge

E-money is a Danish blockchain platform for payment based on Cosmos technology. Supported currencies by e-money currently are CHF, EUR, DKK, NOK, and SEK. In addition, it is planned to add GBP, USD, and JPY. Furthermore, E-money has its own token called Next Generation Money – NGM.
