EVM Chains

Shuttle currently only supports Injective, when setting your providers you can configure which networks are enabled for that specific provider by sending in a network object like the one bellow (example with Injective).

import {
} from "@delphi-labs/shuttle";
import { bech32 } from "bech32";
import { Address } from "ethereumjs-util";
const INJECTIVE_MAINNET: Network = {
name: "Injective Mainnet",
chainId: "injective-1",
chainPrefix: "inj",
rpc: "",
rest: "",
defaultCurrency: {
coinDenom: "INJ",
coinMinimalDenom: "inj",
coinDecimals: 18,
coinGeckoId: "injective",
gasPrice: "0.0005inj",
evm: {
deriveCosmosAddress: (ethAddress: string): string => {
const addressBuffer = Address.fromString(
return bech32.encode("inj", bech32.toWords(addressBuffer));
fromEthChainToCosmosChain: (chainId: number): string => {
return fromInjectiveEthereumChainToCosmosChain(chainId);

As you can notice, evm chains require an extra configuration object evm, this is so that Shuttle can connect to Metamask and similar wallets.
