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)


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.


Basepoint is a Point of Sale (PoS) application that allows retail and businesses to send assets across chains. Basepoint includes software and hardware that actually lets you print receipts of your transactions. It’s built on Base, powered by Optimism and enabled by Superchain and Layer Zero.


L2Vista is a Layer-2 block explorer designed to simplify and illuminate cross-chain transactions, solving the fragmentation problem Web3 faces with transaction data. L2Vista supports Optimism, Base, Zora and Mode and even features AI-powered search for natural language queries.


Ally.ai is taking AI from a generative phase to an agent phase by creating a personal agent for your web3 ecosystem. The AI can perform tasks like generating and minting NFTs, deploying smart contracts, explaining topics, etc.
