ERC-8004: Trustless Agents on TRON & BSC

On-chain identity, reputation, and validation for autonomous agents on TRON. Now live on TRON Mainnet + BSC Mainnet!

Overview

ERC-8004 provides three registries on TRON and BSC blockchains:

• - Identity Registry - TRC-721 agent identities with registration metadata
• Reputation Registry - Signed feedback scores between agents/clients
• Validation Registry - Independent verification (zkML, TEE, stakers)

Multi-Chain: Same protocol works on TRON and BSC (BNB Smart Chain) - both fully deployed!

Quick Reference

Register Agent

Private Key Setup

Networks

TRON Networks

Note: TRON deployments implement TRC-8004 (TRON version of ERC-8004). Query scripts use compatibility mode:

• - ✅ Always available: ownerOf, tokenURI (ERC-721 standard)
• ⚠️ May vary: agentURI, getAgentWallet, agentExists (ERC-8004 extensions)

BSC Networks

Note: BSC deployments use full ERC-8004 specification with all standard methods.

Multi-Chain Usage:
CODEBLOCK2

Contract addresses and ABIs in lib/contracts.json.

Registration File Format

CODEBLOCK3

Template at templates/registration.json.

Reputation Scores

The reputation system uses signed fixed-point numbers (value + valueDecimals):

Trust Models

ERC-8004 supports three pluggable trust models:

• - Reputation-based - Client feedback with scores, tags, and metadata
• Crypto-economic - Stake-secured validation with economic incentives
• Crypto-verification - TEE attestations and zkML proofs

Dependencies

• - node & npm - JavaScript runtime and package manager
• INLINECODE26 - TRON JavaScript SDK (npm install tronweb)
• Private key configuration (choose one):

• - IPFS: Set PINATA_JWT for uploads, or upload manually

TRON-Specific Features

Address Format

• - TRON uses Base58 addresses starting with 'T' (e.g., TFLvivMdKsk6v2GrwyD2apEr9dU1w7p7Fy)
• Scripts automatically handle address conversion

Network Identifiers

• - Mainnet: tron:728126428 (TRON chain ID)
• Use in registration files: INLINECODE34

Energy & Bandwidth

• - TRON uses Energy and Bandwidth instead of gas
• Scripts set feeLimit: 1000000000 (1000 TRX max)
• Actual costs are typically much lower

Script Reference

All scripts support multi-chain (TRON + BSC):

• - register.js - Register new agent on-chain
• query.js - Query agent info and reputation
• feedback.js - Submit feedback/reputation scores
• set-uri.js - Update agent metadata URI

Run any script without arguments to see detailed usage information.

Troubleshooting

"TRONPRIVATEKEY not set"

"Insufficient balance"

• - Ensure your wallet has TRX for transaction fees
• Get testnet TRX from Nile Faucet

"Not the owner"

• - Only the agent owner can update URI or metadata
• Check ownership with INLINECODE36

Security Notes

• - Never commit private keys to version control
• Use environment variables for sensitive data
• Test on Nile testnet before mainnet deployment
• Verify contract addresses in INLINECODE37
