The Role of Block Explorers in Blockchain Transparency

Blockchain's foundational promise is transparency — every transaction publicly verifiable by anyone. TetScan, Tetreum's block explorer, makes this promise real with a full-featured interface for exploring every aspect of on-chain activity.

What You Can Do on TetScan

• Look up any transaction by hash to see its status, gas used, and decoded input data
• View any wallet address's full transaction history and token balances
• Verify smart contract source code so users can audit your contracts
• Monitor token transfers and track specific token activity
• Trace internal transactions to see every call within a complex transaction

Verifying Smart Contracts

1. 1Deploy your contract to Tetreum
2. 2Navigate to your contract address on TetScan
3. 3Click "Verify and Publish" under the Contract tab
4. 4Select your compiler version and optimization settings
5. 5Paste your Solidity source code or upload your project files
6. 6TetScan verifies the bytecode matches — your contract is now transparent

"An unverified contract is a black box. In DeFi, users should never deposit into a contract they cannot read. Verification is not optional — it's a minimum standard of transparency." — Network Team

Using the GraphQL API

For developers who need to query on-chain data programmatically, TetScan's GraphQL API provides powerful filtering capabilities that go far beyond standard JSON-RPC methods. Query by block range, address, event topic, token transfer amount, and more — all in a single typed request.
