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

# TRON Mainnet
node scripts/register.js --uri "ipfs://..." --chain tron --network mainnet

# TRON Testnet
node scripts/register.js --uri "ipfs://..." --chain tron --network nile

# BSC Mainnet
node scripts/register.js --uri "ipfs://..." --chain bsc --network mainnet

# BSC Testnet
node scripts/register.js --uri "ipfs://..." --chain bsc --network testnet

# Register without URI (set later)
node scripts/register.js --chain tron --network nile

Private Key Setup

# Set once, works for both TRON and BSC
export TRON_PRIVATE_KEY="your_64_character_hex_private_key"

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

Network	Status	Identity Registry	Reputation Registry	Validation Registry
BSC Mainnet	Live	`0x8004A169FB4a3325136EB29fA0ceB6D2e539a432`	`0x8004BAa17C55a88189AE136b182e5fdA19dE9b63`	`0x8004Cc8439f36fd5F9F049D9fF86523Df6dAAB58`

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

Multi-Chain Usage:

# TRON
node scripts/register.js --uri "ipfs://..." --chain tron --network mainnet

# BSC
node scripts/register.js --uri "ipfs://..." --chain bsc --network mainnet

Reputation Scores

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

Tag	Meaning	Example	value	decimals
quality	Quality (0-100)	87/100	87	0
uptime	Uptime %	99.77%	9977	2
yield	Yield %	-3.2%	-32	1
latency	Latency ms	560ms	560	0

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
tronweb - TRON JavaScript SDK (npm install tronweb)
Private key configuration (choose one):
- Environment variable: TRON_PRIVATE_KEY or PRIVATE_KEY
- File: ~/.clawdbot/wallets/.deployer_pk
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: tron:728126428:TFLvivMdKsk6v2GrwyD2apEr9dU1w7p7Fy

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
search.js - Semantic search agents via search-service API
feedback.js - Submit feedback/reputation scores
set-uri.js - Update agent metadata URI

Run any script without arguments to see detailed usage information.

Examples

Complete Agent Workflow

# 1. Set private key (works for both TRON and BSC)
export TRON_PRIVATE_KEY="your_private_key"

# 2. Register agent on TRON testnet
node scripts/register.js --uri "ipfs://QmYourHash" --chain tron --network nile

# 3. Query agent info (use ID from step 2)
node scripts/query.js agent 1 --chain tron --network nile

# 4. Submit feedback
node scripts/feedback.js --agent-id 1 --score 95 --tag1 "quality" --chain tron --network nile

# 5. Query reputation
node scripts/query.js reputation 1 --chain tron --network nile

# 6. Update URI if needed
node scripts/set-uri.js --agent-id 1 --uri "ipfs://QmNewHash" --chain tron --network nile

# 7. Semantic search by keyword
node scripts/search.js --query "market order" --url "https://tn-search-service.bankofai.io" --chain-id 3448148188

# 8. Multi-chain search (choose chain(s) based on user request)
node scripts/search.js --query "x402 a2a payment" --chains "56,3448148188"

Multi-Chain Examples

# Register on BSC testnet
node scripts/register.js --uri "ipfs://..." --chain bsc --network testnet

# Query agent on BSC mainnet
node scripts/query.js agent 1 --chain bsc --network mainnet

# Submit feedback on TRON mainnet
node scripts/feedback.js --agent-id 1 --score 98 --tag1 "quality" --chain tron --network mainnet

# Search only BSC mainnet agents
node scripts/search.js --query "a2a x402" --chain-id 56

# Search all configured chains in search-service
node scripts/search.js --query "merchant recharge" --chains all

Search Chain Selection Rule

Always choose search chain(s) from user intent instead of hardcoding a default chain.
Use --chain-id <id> for a single chain request.
Use --chains "<id1,id2>" for cross-chain requests.
Use --chains all when user asks to search all available networks.
Common chain IDs:
- TRON Nile: 3448148188
- BSC Mainnet: 56

Troubleshooting

"TRON_PRIVATE_KEY not set"

# Option 1: Environment variable (recommended)
export TRON_PRIVATE_KEY="your_64_character_hex_private_key"

# Option 2: File storage
mkdir -p ~/.clawdbot/wallets
echo "your_private_key" > ~/.clawdbot/wallets/.deployer_pk
chmod 600 ~/.clawdbot/wallets/.deployer_pk

"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 query.js agent <id>

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 lib/contracts.json

Compatible with ERC-8004 specification. TRON implementation is TRC-8004.
