ERC20 TRC20 Address Monitoring: Wallet Address Configuration Patterns and Precautions in TG-Staff Content Moderation

In the context of Telegram customer service for Web3, cryptocurrency, and NFT projects, wallet addresses are the most sensitive and error-prone information carriers. An agent mistakenly sending a payment address, a tampered address, or even an employee deliberately sending a personal address instead of an official one can lead to customer fund loss, team reputation damage, or even compliance disputes.

The built-in content moderation module of TG-Staff Professional Edition allows operators to configure on-chain wallet addresses such as ERC20, TRC20, BTC as risk words, requiring secondary confirmation or direct interception when agents send them. This article starts from address format recognition and guides you step by step to build a reliable wallet address monitoring defense.

Why Monitor Wallet Addresses in Telegram Customer Service?

If your team is involved in the following scenarios, wallet address monitoring is almost indispensable:

• Cryptocurrency exchanges or wallet services: Customer service agents need to reply to users about deposit/withdrawal addresses but must never send payment addresses themselves.
• NFT projects or blockchain games: Customer service personnel may be asked to assist users in submitting wallet addresses, posing risks of accidental or malicious address replacement.
• Cross-border marketing and payment: Involving USDT (TRC20/ERC20) collections, if an agent sends a wrong address, funds cannot be recovered.
• Web3 SaaS tools: Operators guide users through wallet binding via bots, and agents may inadvertently leak addresses while assisting in the backend.

Traditional solutions rely on “manual review + screenshot reporting,” which are inefficient and hard to trace. TG-Staff’s content moderation, through automated monitoring, detects and intercepts messages the moment they are sent, while recording a complete audit trail.

Common On-Chain Address Format Recognition: ERC20, TRC20, and BTC

Before configuring risk phrases, you need to accurately distinguish address characteristics of different chains; otherwise, you may miss key addresses or generate many false positives. Below is a comparison of the three most mainstream on-chain address formats.

ERC20 (Ethereum and Compatible Chains) Address Features

• Prefix: Fixed starting with 0x (hexadecimal identifier).
• Length: 42 characters total (including 0x), i.e., 40 hexadecimal characters.
• Encoding: Hexadecimal (0-9, a-f); some implementations are case-sensitive (EIP-55 checksum).
• Compatible Chains: BSC (BEP-20), Polygon, Avalanche C-Chain, Arbitrum, Optimism, and other EVM-compatible chains use the same format.

Example: 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B

TRC20 (Tron Chain) Address Features

• Prefix: Fixed starting with uppercase letter T.
• Length: 34 characters.
• Encoding: Base58 (does not include confusing characters like 0/O/I/l), so addresses never contain 0, O, I, or l.
• Note: TRC20 addresses share the same format as TRC10 addresses; no distinction is needed during monitoring.

Example: TXYZopYRdj2D9XRtbG411XZZ3kM5VkAeBf

BTC (Bitcoin) Address Features

BTC addresses come in three common formats, all of which should be covered:

Format Type	Prefix	Length (characters)	Encoding	Example
Legacy P2PKH	1	26-34	Base58	1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa
P2SH (multisig/segwit compatible)	3	26-34	Base58	3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
Bech32 (native segwit)	bc1	42-62	Bech32	bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq

Key Point: BTC address length is variable (26-62 characters) and prefixes vary widely; it is recommended to use prefix fragments rather than full addresses when configuring.

Wallet Address Configuration Steps in TG-Staff Content Moderation

The following operations are performed in the TG-Staff Pro console. If you haven’t used it yet, you can sign up for a free 3-day trial.

Step 1: Create a Risk Phrase Group and Add Wallet Address Keywords

1. Log in to the TG-Staff App Console and navigate to the Content Moderation module.
2. Click “Create Risk Phrase Group” and enter a group name (e.g., “Wallet Address Monitoring”).
3. In the keyword list, add the address patterns you wish to monitor. Two strategies are recommended:
   • By prefix (recommended): Enter 0x to cover all EVM-compatible chain addresses; enter T to cover TRC20 addresses; enter 1, 3, bc1 to cover BTC addresses.
   • By full address: If you only want to monitor specific official payment addresses, paste the full address directly (e.g., 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B).
4. Set the trigger action:
   • Double confirmation: When an agent sends a message containing the address, a popup prompts “This message contains a monitored address. Confirm sending?” The message is sent only after the agent confirms.
   • Block sending: The message is directly blocked and will not be sent; the agent sees a “Send failed” prompt.

Step 2: Link the Risk Phrase Group to a Project

1. On the Content Moderation page, find the risk phrase group you just created and click “Link Project.”
2. Select the Telegram Bot projects you want to monitor from the dropdown list. You can link the same phrase group to multiple projects or create different phrase groups for different projects.
3. After confirming the link, all agent messages in that project will be subject to content moderation.

Best Practice: It is recommended to create separate risk phrase groups for different business lines. For example, create a phrase group for “official payment addresses” (using the full address) and another for “user-submitted addresses” (using prefixes), and link them to different projects to avoid rule conflicts.

Step 3: Test and Audit Trigger Records

1. Log in to the web portal with an agent account and send a message containing a wallet address (e.g., 0x1234567890abcdef1234567890abcdef12345678) to a test user.
2. Depending on your configured action, observe whether a pop-up (confirmation prompt) appears or the message fails to send (blocked).
3. Return to the Audit Log page in Content Moderation to view all trigger records, including:
   • Trigger Time: Precise to the second.
   • Agent: The agent account that sent the message.
   • Session: The associated customer service session ID.
   • Risk Phrase: The specific keyword that was matched (e.g., 0x or the full address).
   • Action Result: Whether it was blocked or required confirmation.

Audit logs can be used for regular reviews to identify high-frequency false positives or false negatives, and to detect any agents attempting to bypass rules.

Best Practices and Notes for Wallet Address Monitoring

• Prioritize Address Fragments: Unless you need to monitor specific official addresses, use prefixes (0x, T, 1, 3, bc1) to cover entire chains and reduce the workload of maintaining individual addresses. However, be mindful of false positive rates—if false positives are too high, consider adding exclusion rules (e.g., adding a “test address” whitelist) to the phrase group.
• Update Address Library Regularly: If your project changes its official payment address, immediately update the full address in the risk phrase group. If you add a new chain (e.g., Solana’s So11111111111111111111111111111111111111112 format), add the corresponding prefix promptly.
• Combine with Session Routing to Reduce Risk: In addition to content moderation, use TG-Staff’s Session Routing feature (e.g., “Online First” mode) to ensure sensitive sessions are prioritized to senior agents, reducing the chance of mistakes by new employees.
• Case Sensitivity and Encoding: ERC20 addresses are case-sensitive (EIP-55 checksum), but TG-Staff’s keyword matching is case-insensitive by default, so 0xAb5801... and 0xab5801... will both be matched. If using full addresses, consider adding both uppercase and lowercase versions.
• Monitor Other Chain Addresses: Supports any text-form wallet address, including Solana (So..., G...), BSC (same format as ERC20), Polygon, etc. Simply fill in the corresponding address fragments in the risk phrase group.

Frequently Asked Questions

Q: When configuring wallet address monitoring, should I use the full address or address fragments?

A: It is recommended to use address fragments (e.g., prefixes like 0x, T, bc1) to cover all addresses on that chain, reducing maintenance costs. If you need to monitor a specific address (e.g., an official payment address), use the full address to avoid false positives.

Q: Which chain addresses does TG-Staff’s content moderation support?

A: It supports any text-form wallet address, including but not limited to ERC20 (Ethereum and compatible chains), TRC20 (Tron), BTC (Bitcoin), Solana, BSC, and more. Simply fill in the corresponding address or fragment in the risk phrase group.

Q: What happens if an agent sends a message that hits a risk phrase?

A: Depending on your configuration, two actions can be triggered: “Confirmation Prompt”—the agent sees a pop-up and must confirm before sending; or “Block Sending”—the message is directly intercepted and cannot be sent. All trigger records can be viewed in the audit log.

Q: Does address monitoring affect normal user chat?

A: No. Content moderation only monitors messages sent by agents; it does not intercept or review content sent by end users to the Bot, ensuring a smooth user experience.

Q: Can I set different address monitoring rules for different projects?

A: Yes. You can create multiple risk phrase groups in TG-Staff, each containing different addresses or keywords, and link them to different Bot projects for fine-grained compliance control.
