![]() ![]() Polygon supports the creation of smart contracts and enables interoperability by allowing for the cross-communication of smart contracts launched on its blockchain. Similar to BSC, the Polygon blockchain uses a Proof of Stake consensus algorithm. This is due to having several centralized entities, such as the 21,000 node validators which are either directly or indirectly owned by Binance and responsible for the network’s lower gas fees. ![]() However, BSC does have some drawbacks, including less decentralization. Ethereum Smart contracts can easily be migrated to the BSC platform with minimal or no changes to the code. These benefits make BSC more scalable than Ethereum. Some incentives for migrating from Ethereum to BSC are Binance’s lower gas fees and faster transaction times. Like Ethereum, it supports the creation of smart contracts. The Binance Smart Chain (BSC) uses a Proof of Stake consensus algorithm. ![]() Ethereum enforces a maximum amount of gas per block, referred to as the block gas limit. The gas fee must be paid before miners add the transaction to a block. An operation could be sending an amount of ether (Ethereum’s cryptocurrency) from one account to another or deploying a contract. Smart contracts may be created on the Ethereum network.Įvery operation made on the Ethereum blockchain, whether successful or not, must be paid for with a gas fee. At the time of this writing, Ethereum uses a Proof of Work consensus algorithm. The Ethereum blockchain is a decentralized, transparent, and secure public blockchain. Several factors could influence a decision to migrate a smart contract from one blockchain to another. VS Code, or the code editor of your choosingĬonsiderations for migrating between blockchains.To follow along with the tutorial portion of this article, ensure that you have the following: Smart contract migration between chains.Migrating a smart contract to Binance Smart Chain.Migrating a smart contract to Polygon’s testnet (Mumbai).Migrating a smart contract to Ethereum’s testnet (Rinkeby).Setting up a smart contract with Ganache.Demo: Smart contract migration from a local development chain.Considerations for migrating between chains.This article also provides an overview of several blockchains and how they vary with regard to smart contract migration. This smart contract migration guide demonstrates how to migrate a smart contract from a local development chain to individual blockchains, and how to migrate smart contracts between different chains. There are also instances where it makes sense to shift a contract to a different chain in order to debug a contract, to provide additional security, or even to provide access to the contract if it has become inaccessible due to theft or a technical issue. Some obvious reasons are lower gas fees or faster transaction time. There are several reasons why a smart contract might be migrated to another blockchain.
