Replay

For most Web3 users replaying transactions is a challenge. Replay is a user-friendly tool that fetches all recent transactions for a wallet and provides an option to replay failed transactions on the Optimism, Base and Zora networks.

Covalent API: Get a transaction, Get recent transactions for address (v3) and Get paginated transactions for address (v3)

SuperSearch

The SuperSearch widget allows users to easily search for a transaction by a hash or search their account by the wallet address. This enables users to stay on the same page where they are transacting instead of having to go and bring up a block explorer.
