kandi X-RAY | optics-monorepo Summary

optics-monorepo is a TypeScript library typically used in Blockchain, Ethereum applications. optics-monorepo has no bugs, it has no vulnerabilities and it has low support. However optics-monorepo has a Non-SPDX License. You can download it from GitHub.

Optics is a cross-chain communication system. It handles passing raw buffers between blockchains cheaply, and with minimal fuss. Like IBC and other cross-chain communication systems, Optics creates channels between chains, and then passes its messages over the channel. Once a channel is established, any application on the chain can use it to send messages to any other chain. Compared to IBC and PoS light client based cross-chain communication, Optics has weaker security guarantees, and a longer latency period. However, Optics may be implemented on any smart contract chain, with no bespoke light client engineering. Because it does not run a light client, Optics does not spend extra gas verifying remote chain block headers.

            Why Metamask if web3.js can interact directly with ganache?
            Asked 2022-Mar-30 at 17:55

            I am new to blockchain app development, I saw a project where ganache accounts are imported into Metamask, then web3.js is used to access and print those accounts and balances on Frontend (user interface).

            If web3.js can directly access ganache blockchain accounts and balances, why do we need Metamask in between?

            ...

            If web3.js can directly acccess ganache blockchain accounts and balances, why we need metamask in between?

            In this case, you don't need MetaMask to sign the transaction, as the node (Ganache) holds your private key.

            But in a public environment (testnets and mainnet), the node doesn't hold your private key, so you'd need to sign the transaction using MetaMask (or any other tool that holds the private key).

            The assets endpoint (docs) has the asset_contract_address filter that allows you to filter by a contract address. Which will effectively allow you to paginate through all NFTs of the contract (that Opensea knows of).

            Should I use the elrond devnet instead of the testnet for development?
            Asked 2022-Mar-08 at 09:03

            I've been using the testnet lately and I encounter issues: they reset it very often and the service is down for multiple hours and sometimes have bugs.

            Should I use the devnet? From what I've understood it's more stable and they reset it less often?

            I have a backend in js that uses the elrond-sdk-erdjs and I'm confused because there is no function that initializes the https://devnet-gateway.elrond.com only the testnet. Is there a reason?

            The testnet is pretty volatile and it is reset very often (maybe weekly), without any warnings. Elrond recommends developers to use the devnet, it is reset maybe once every 3-4 months, so it's more stable.

            it appears your env variables are not set correctly, and it looks like in this case it's your WEB3_INFURA_PROJECT_ID.

            You can fix it by setting the variable in your .env file and adding dotenv: .env to your brownie-config.yaml.

            brownie-config.yaml:

            dotenv: .env .env:

            export WEB3_INFURA_PROJECT_ID=YOUR_PROJECT_ID_HERE Remember to save these files.

            Additionally, you should be on at least brownie version v1.14.6. You can find out what version you're on with:

            Weth is different from other token, you're not able to use swapTokensForTokens. We must use the swapEthForTokens function instead, and you have to declare the data option separately.
