Best Smart Contract Platforms in Brazil

Meter is a high performance infrastructure that allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter is a Layer 1 and Layer 2 blockchain protocol. The Meter system consists of two tokens: MTRG, the governance token (eMTRG is the ERC20 version), and MTR, the low-volatility currency token. Financial assets should flow freely among blockchains. Meter’s HotStuff-based consensus allows 1000s of validator nodes, making Meter the most decentralized Layer 2 for Ethereum. Meter processes thousands of transactions per second and transactions are confirmed almost instantly. Meter Passport allows assets and smart contracts travel and communicate across heterogeneous blockchains for the best price, liquidity and yield. Meter is an Ethereum Compatible with unique enhancements. Unlike other Layer 2, DEXes build on Meter are front running/MEV resistant, fast and uncensorable.

Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

A decentralized peer to peer work contract or payroll decentralized application. There are currently two kinds of pacts that can be made using ChainPact - Gig pact and Proposal Pact. Gig Pact enables anyone to create a freelancing agreement or employment contract on the blockchain. This is a time based contract, where the employer pays the agreed upon payment at agreed upon intervals. The contract acts as an escrow smart contract for the payment. Further, a fundraiser or a kickstarter type campaign on blockchain can be created using the Proposal pact smart contract. It allows the creator to specify a certain voting start time and duration. So contributors can vote at a later date whether to disburse the collected funds to the creator's chosen account or somewhere else (like refunded back to the contributors)

Secret Network is the first blockchain with data privacy by default, allowing you to build and use applications that are both permissionless and privacy-preserving. This unique functionality protects users, secures applications, and unlocks hundreds of never-before-possible use cases for Web3. Whether you’re a developer, an artist, an entrepreneur, or a dreamer, you can become a Secret Agent and contribute to Secret Network. Check out the many contributors, collaborators, applications, and backers that make up the Secret Network ecosystem. With blockchain technology, we have the potential to create a more empowering and inclusive internet, what is often referred to as Web3. But current blockchains are public by default, exposing all data to everyone and putting users at risk. In order to enable meaningful use cases and achieve global adoption, users and organizations need control over how their data is used and shared, a concept we call programmable privacy.

Shiden Network is a multi-chain decentralized application layer on Kusama Network. Kusama Relaychain does not support smart contract functionality by design - Kusama Network needs a smart contract layer. This is where Shiden Network comes in. Shiden supports Ethereum Virtual Machine, WebAssembly, and Layer2 solutions from day one. The platform supports various applications like DeFi, NFTs and more. SDN token holders can stake their tokens on favorite dApps so that both nominators and the dApps developer can earn SDN tokens. If you are trying to deploy Solidity smart contracts, you have 2 ways to compile your smart contract: using Ethereum tools, or using Solang (a Solidity to WASM compiler). After compiling your contract, you can deploy it on our testnet, Dusty Network.

Scale your DApp to Polkadot with Acala, an Ethereum-compatible smart contract platform optimized for DeFi. Acala is the decentralized finance network and liquidity hub of Polkadot. It’s a layer-1 smart contract platform that’s scalable, Ethereum-compatible, and optimized for DeFi with built-in liquidity and ready-made financial applications. With its trustless exchange, decentralized stablecoin (aUSD), DOT Liquid Staking (LDOT), and EVM+, Acala lets developers access the best of Ethereum and the full power of substrate. Access DOT-based assets and derivatives, Polkadot-native decentralized stablecoin, Polkadot ecosystem assets, and cross-chain assets from Bitcoin, Ethereum and beyond. Acala’s chain is customized for DeFi and can continue to upgrade without forks to integrate new features requested from developers. For example, on-chain ‘keepers’ automate protocol execution to better manage risks and improve user experience, or transaction fees payable with virtually any token.

A Proof-of-Stake chain utilizing secure JavaScript smart contracts to rapidly build and deploy DeFi. Save time by using our pre-built smart contract components and dapps. They’re secure, composable, and let you get your project out the door pronto. Agoric offers a library of reusable, composable components coded by experienced community members just like you. Use familiar tooling to build smart contracts in secure JavaScript. As you grow, be confident your hiring pool of experienced developers won't run dry! By eliminating categories of complex security bugs, Agoric provides builders with a safer environment to quickly harden your contracts. We’ve been working in smart contracts for decades, since long before it was called a blockchain. Agoric was founded on open-source principles optimized for a booming, collaborative, public economy. Agoric components help keep your focus on building your application, not on complex protocol integrations and third-party code.

Next generation layer 2 for Ethereum dApps. Use your favorite tools and scale your dApp at the lowest cost. An aggregator plays the same role that a node plays in Ethereum. Client software can do remote procedure calls (RPCs) to an aggregator, using the standard API, to interact with an Arbitrum chain. The aggregator will then make calls to the EthBridge and produce transaction results to the client, just as an Ethereum node would. Most clients will use an aggregator to submit their transactions to an Arbitrum chain, although this is not required. There is no limit on how many aggregators can exist, nor on who can be an aggregator. To improve efficiency, aggregators will usually package together multiple client transactions into a single message to be submitted to the Arbitrum chain. Arbitrum also supports a privileged Sequencer that can order transactions and give low latency transaction receipts.
