Reown Yttrium

A Flutter plugin that provides blockchain interaction capabilities through the Reown platform, built on top of the WalletConnect Network. This plugin is part of the Yttrium ecosystem, a cross-platform library designed for working with smart accounts in the Ethereum ecosystem.

Overview

Reown Yttrium is a powerful Flutter plugin that enables seamless blockchain interactions in your Flutter applications. It provides essential abstractions and primitives for Wallets and DApps to interact with and implement smart account functionality. A primary goal is to enable externally owned account (EOA) wallets to offer advanced features such as batch transactions and transaction sponsorship to their users.

Usage

Initialization

First, initialize the plugin with your project ID and pulse metadata:

final reownYttrium = ReownYttrium();

await reownYttrium.init(
  projectId: 'your_project_id',
  pulseMetadata: pulseMetadata,
);

Check ERC20 Token Balance

final balance = await reownYttrium.erc20TokenBalance(
  chainId: 'chain_id',
  token: 'token_address',
  owner: 'owner_address',
);

Estimate Transaction Fees

final fees = await reownYttrium.estimateFees(
  chainId: 'chain_id',
);

Prepare Transaction

final preparedTx = await reownYttrium.prepareDetailed(
  chainId: 'chain_id',
  from: 'from_address',
  call: call,
  localCurrency: currency,
);

Execute Transaction

final executionDetails = await reownYttrium.execute(
  uiFields: uiFields,
  routeTxnSigs: routeTxnSigs,
  initialTxnSig: initialTxnSig,
);
