@polywrap/ethereum-plugin-js
The Ethereum plugin wrapper allows the Polywrap JS Client to interact with any EVM based blockchain.
Usage
import {
ethereumPlugin,
Connections,
Connection
} from "@polywrap/ethereum-plugin-js";
export async function main() {
const uri = "wrap://ens/ethereum.polywrap.eth"
// initialize Ethereum Connections store
const connections: Connections = new Connections({
networks: {
mainnet: new Connection({
provider: "..."
}),
matic: new Connection({
provider: window.ethereum
})
},
defaultNetwork: "matic"
});
// initialize the client with the ethereum plugin
client = new PolywrapClient({
plugins: [
{
uri: uri,
plugin: ethereumPlugin({ connections })
}
]
});
// now you can invoke the ethereum plugin by its URI
// NOTE: uses default network "matic"
const getSignerAddress = await client.invoke<string>({
uri,
method: "getSignerAddress",
});
if (!getSignerAddress.ok) throw getSignerAddress.error;
const address = getSignerAddress.value;
// Get a balance from mainnet, by passing in the optional
// "connection" argument.
const getBalance = await client.invoke<string>({
uri,
method: "getBalance",
args: {
address: "0x...",
connection: {
networkNameOrChainId: "mainnet"
}
},
});
if (!getBalance.ok) throw getBalance.error;
const balance = getBalance.value;
console.log("Matic Signer: ", address);
console.log("Mainnet Balance: ", balance);
}
