Contract Interactions

Interact with verified smart contracts on Base

What is Clinical Trials?

The Clinical Trials page is an interactive laboratory where you can experiment with various smart contracts deployed on Base Mainnet. It's a safe way to learn how blockchain transactions work.

📚 Verified Contracts

Explore a wide variety of contract types and functions

🔧 Live Interactions

Call real functions on Base Mainnet with your wallet

📊 Categories

Organized by type: DeFi, NFT, Bridges, Utilities, and more

💡 Educational

Learn by doing - see how transactions work in real-time

Read vs Write Functions

Smart contracts have two types of functions:

📖 Read Functions

Query data from the blockchain without making changes. These are free and don't require gas.

Examples: Check balance, read stored value, get total supply

✍️ Write Functions

Modify blockchain state by sending a transaction. These require gas fees and wallet approval.

Examples: Transfer tokens, mint NFT, increment counter, store data

How to Use Clinical Trials

Step-by-step guide:

1
Connect your wallet - Make sure you're on Base Mainnet
2
Browse contracts - Filter by category or search for specific contracts
3
Try functions - Click buttons to interact with contract functions
4
Fill inputs - Some functions require parameters (numbers, addresses, etc.)
5
Approve transaction - Confirm in your wallet (for write functions)
6
View results - Check the transaction on BaseScan

Understanding Gas

All contracts are on Base Mainnet. Transactions use real ETH and cost real gas fees.

Gas fees on Base are very low compared to Ethereum mainnet:

Typical Gas Costs:

Simple function call (increment counter):~$0.001 - $0.01
Token transfer:~$0.01 - $0.02
Complex interaction (swap tokens):~$0.05 - $0.15

Contract Categories

Contracts are organized into categories for easy navigation:

DeFi

Swaps, lending, liquidity

NFT

Collections and marketplaces

Bridges

Cross-chain transfers

Gaming

On-chain games

Social

Social protocols

Utilities

Tools and helpers

⚠️ Safety Tips

•Start with small amounts to test how contracts work
•Always review transaction details before approving
•Check contract addresses on BaseScan to verify legitimacy
•Read function descriptions to understand what each function does
•Never interact with contracts you don't understand
