**Technology:** Wagmi

React hooks on Viem for wallet connection, contract calls, and token balance subscriptions in Opyn's trading app and Bitlauncher's auctions.

## Project evidence

- [Opyn](https://gaboesquivel.com/project/opyn) (2024)
- [Bitlauncher](https://gaboesquivel.com/project/bitlauncher) (2023)

## Implementation

- Wired Opyn wallet connect and contract interactions on Arbitrum Testnet with Wagmi and Viem.
- Subscribed to token balances in Bitlauncher's wallet UI so auction screens stayed in sync with chain state.
- Configured multichain connectors in Bitlauncher for EOS and EVM wallets through a single React layer.
