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)

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

Registration File Format

{ "type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1", "name": "your-agent-name", "description": "Agent description...", "image": "ipfs://...", "services": [ { "name": "A2A", "endpoint": "https://agent.example/.well-known/agent-card.json", "version": "0.3.0" }, { "name": "MCP", "endpoint": "https://mcp.agent.tron/", "version": "2025-06-18" } ], "registrations": [ { "agentRegistry": "tron:728126428:TFLvivMdKsk6v2GrwyD2apEr9dU1w7p7Fy", "agentId": "1" } ], "supportedTrust": ["reputation", "crypto-economic", "tee-attestation"] }

Template at templates/registration.json .

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.

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
