DIDLab network reference

Use these values when configuring wallets, scripts, developer tools, or classroom applications. The native network asset and the TT platform token are intentionally distinct.

Verified network values

These are the public DIDLab values used throughout the portal and deployment guides.

Network name: DIDLab Blockchain
Chain ID: 252501
Chain ID (hex): 0x3da55
Execution client: Hyperledger Besu
Consensus: QBFT
Native currency: TRUST
RPC: https://eth.didlab.org
Explorer: https://explorer.didlab.org
TT token: 0xe15a77668A01A90c57c8F4De0021e12DF933CBD5

Native asset

TRUST

TRUST is the chain's native currency. Wallets use it to pay gas and it can be transferred without calling an ERC-20 contract.

ERC-20 platform token

TT

TT is the DIDLab TrustToken contract used by platform and classroom workflows. It is not the native gas currency.

Verify the chain independently

A wallet configuration is more trustworthy when you can independently query the RPC endpoint and verify the expected chain ID.

eth_chainId

curl -sS -X POST https://eth.didlab.org \
  -H 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'

Expected result

The JSON-RPC response contains 0x3da55, which is decimal chain ID 252501.

Operational links

Use the official DIDLab portal services rather than copying unknown RPC or contract values from third-party pages.
