Interact With Smart Contracts

Interaction with Smart Contracts

Interacting with a smart contract involves calling read or write methods on a specific contract. These functions can range from simple standard ERC-20 methods to complex smart contract logic invocations. Fireblocks offers several ways to interact with smart contracts:

1. Interact with a Deployed Smart Contract via the Fireblocks Console - Learn more here.
2. Use the Fireblocks EVM Web3 Provider or Local JSON RPC Tools.
3. Use the Fireblocks REST API.

Using the Web3 Provider and Local JSON RPC Tools

These tools allow you to seamlessly integrate Fireblocks into your codebase.

EVM Web3 Provider

The EVM Web3 Provider is an EIP1193 compatible provider that can be integrated into your EVM client library (such as ethers, web3, viem) with a simple configuration.

Learn more about the Web3 Provider in the following developer guide.

Local JSON RPC

Local JSON RPC provides the same functionality as the Web3 provider but is designed for customers who do not use JavaScript-based tools for their smart contract development and integration.

Learn more about the Local JSON RPC in the following developer guide.

Using the Fireblocks REST API

Direct interaction with smart contracts via the Fireblocks API can be achieved by calling the Create Transaction API endpoint. To perform a contract call, set the operation parameter to CONTRACT_CALL and include the contractCallData parameter in the extraParams object of the POST request body.

The contractCallData value should be the hex-encoded data you want to pass to the contract. This can be structured using well-known libraries such as web3.js, ethers.js, or similar.
