Add Support for Arbitrum, Fantom, Heco, and Optimism

Proposal Summary

Trust Wallet is looking to add support for the following EVM-compatible blockchains and scaling protocols:

• Arbitrum
• Fantom
• Heco
• Optimism

These blockchains will give Trust Wallet users access to a broader selection of DApps, and enable higher speed and lower-cost transactions.

What is Arbitrum?

Arbitrum is an Ethereum optimistic rollup-based layer 2 scaling protocol developed by Offchain Labs. The Arbitrum One sidechain works by combining multiple pieces of data from a smart contract execution before writing a cryptographic hash of the "rolled up" transaction to the Ethereum blockchain. This reduces Ethereum computing resources while preserving privacy.

Arbitrum is supported by many popular DApps including SushiSwap, Curve, Aave, Balancer, Uniswap and more.

What is Fantom?

Fantom is a smart contract platform that seeks to improve decentralization, security, and speed. It is powered by a protocol called Lachesis which allows the consensus mechanism to be both asynchronous and Byzantine fault-tolerant, i.e. secure and decentralized without sacrificing speed.

What is Heco?

Heco is short for Huobi Ecochain, a public EVM compatible blockchain developed by Huobi Global. Launched in December 2021, HECO acts as a competitor to Binance's Smart Chain. HECO also offers the ability to transfer Smart Chain tokens to HECO at a 1:1 peg for hBSC offers gas fee discounts in accordance with users' Huobi Token holdings.

What is Optimism?

Optimism is an Ethereum Layer 2 scaling solution that pioneered the concept of optimistic rollups to reduce transaction fees and latency. Optimism supports all Ethereum development tools, thus making the process of porting Dapps fast and simple. Optimism is currently supported by key projects including 1Inch, Celar, Uniswap, Debank and others.

Benefit to Trust Wallet

Support for additional blockchains allows Trust Wallet users to store a greater number of coins and tokens. Furthermore, layer 2 supports enables the benefits of DeFi/Dapps with lower fees and transaction times.
