Injective Typescript CosmJs Support

Injective не поддерживается в пакетах @cosmjs. Настоятельно рекомендуется использовать наши пакеты @injectivelabs для взаимодействия с Injective.
Если вы знакомы с пакетами @cosmjs, то мы экспортируем аналогичные интерфейсы/классы, которые работают точно так же, как и классы на @cosmjs, но имеют поддержку Injective.
Использование с помощью Keplr
Ниже приведен пример использования альтернатив @injectivelabs из пакетов @cosmjs с помощью Keplr:

import { PrivateKey, InjectiveStargate, } from "@injectivelabs/sdk-ts"; import { OfflineDirectSigner } from "@cosmjs/proto-signing"; import { assertIsBroadcastTxSuccess } from '@cosmjs/stargate'

(async () => { // Enable Keplr await window.keplr.enable(chainId);

// Get the offline signer const offlineSigner = window.getOfflineSigner(chainId); const [account] = await offlineSigner.getAccounts();

// Initialize the stargate client const client = await InjectiveStargate.InjectiveSigningStargateClient.connectWithSigner( "https://lcd-cosmoshub.keplr.app/rest", offlineSigner, ); })

const amount = { denom: "inj", amount: amount.toString(), }; const fee = { amount: [ { denom: "inj", amount: "5000000000000000", }, ], gas: "200000", };

const result = await client.sendTokens( account.address, recipient, [amount], fee, "" );

assertIsBroadcastTxSuccess(result);

if (result.code !== undefined && result.code !== 0) { alert("Failed to send tx: " + result.log || result.rawLog); } else { alert("Succeed to send tx:" + result.transactionHash); } })()

Использование в среде CLI/Node
Ниже приведен пример использования альтернатив @injectivelabs из пакетов @cosmjs в среде узла или CLI:

import { PrivateKey, InjectiveStargate, InjectiveDirectEthSecp256k1Wallet, } from "@injectivelabs/sdk-ts"; import { OfflineDirectSigner } from "@cosmjs/proto-signing"; import { Network, getNetworkInfo } from "@injectivelabs/networks"; import { getStdFee } from "@injectivelabs/utils";

(async () => { const network = getNetworkInfo(Network.Testnet); const privateKeyHash = process.env.PRIVATE_KEY as string; const privateKey = PrivateKey.fromHex(privateKeyHash); const injectiveAddress = privateKey.toBech32();

const wallet = (await InjectiveDirectEthSecp256k1Wallet.fromKey( Buffer.from(privateKeyHash, "hex") )) as OfflineDirectSigner; const [account] = await wallet.getAccounts();

const client = await InjectiveStargate.InjectiveSigningStargateClient.connectWithSigner( network.rpc as string, wallet );

const recipient = injectiveAddress; const amount = { denom: "inj", amount: "1000000000", };

const txResponse = await client.sendTokens( account.address, recipient, [amount], getStdFee(), "Have fun with your star coins" );

if (txResponse.code !== 0) { console.log(`Transaction failed: ${txResponse.rawLog}`); } else { console.log( `Broadcasted transaction hash: ${JSON.stringify( txResponse.transactionHash )}` ); } })();
