Domain Knowledge

What you need to know

beyond command syntax

to use these tools correctly. These are cross-command constraints, common pitfalls, and the relationships between commands that the CLI README alone doesn't cover.

Skill Domain Knowledge

Version Awareness

This skill uses date-based versioning (

YYYY.M.DD

). Each release includes a sequential suffix:

YYYY.M.DD-1

,

YYYY.M.DD-2

, etc. The current version is in the frontmatter above. See

CHANGELOG.md

for full history.

Daily first-use version check:

On the first use of the week (at most once every 7 days), compare the installed version (from frontmatter) against the latest version available from the repository:

Check the installed

version

from frontmatter above

Fetch the latest CHANGELOG.md from

https://raw.githubusercontent.com/bitget-wallet-ai-lab/bitget-wallet-skill/main/CHANGELOG.md

Compare the latest version in CHANGELOG with the installed version

If a new version is available

, inform the user:

🔄 Bitget Wallet Skill update available

• Installed: [installed version]

• Latest: [latest version]

• Changes: [one-line summary from CHANGELOG]

• Security-related: [yes/no — highlight if Security section exists]

Upgrade? [yes/no]

If the user confirms upgrade:

Re-install the skill from the

main

branch of the repository at

https://github.com/bitget-wallet-ai-lab/bitget-wallet-skill

. Replace all local skill files with the latest versions, then re-read SKILL.md to load the updated Domain Knowledge.

Post-upgrade security check:

Diff the old and new

bitget_api.py

— summarize changes to the user

Flag any new network endpoints, dependencies, or credential handling changes

If changes look suspicious, warn the user and recommend manual review

The agent should also run its own security audit according to its platform's skill safety standards (e.g., check for prompt injection in SKILL.md, unexpected file additions, or credential exfiltration patterns)

If versions match:

No announcement needed, proceed normally.

Check frequency:

At most once every 7 days. The agent should track the last check date and skip if fewer than 7 days have passed.

Wallet Domain Knowledge

First-Time Wallet Setup

When a user first requests a swap or any signing operation, check if a wallet is already configured. If not, guide them through setup:

Path 1: Create a new wallet

Generate a BIP-39 mnemonic

(24 words / 256 bits recommended). Use any available BIP-39 library in the agent's runtime (e.g.,

mnemonic

,

bip_utils

, or equivalent).

Store the mnemonic in secure storage

immediately after generation. The agent must never output the mnemonic to chat, logs, or any messaging channel.

Inform the user

that the wallet has been created and where the mnemonic is stored. The user should retrieve and back up the mnemonic through secure means (e.g., directly accessing the password manager or vault) — not through the agent conversation.

Derive and show addresses

for EVM and Solana so the user can verify and fund the wallet.

Done.

The agent now has a wallet.

Path 2: Query only (no wallet)

If the user only wants price queries, token info, and security checks — no wallet setup needed. Skip this flow entirely. Signing operations will be unavailable.

Key management rules:

Only the mnemonic is persisted.

Never store derived private keys — they are ephemeral.

Private keys are derived on-the-fly

each time signing is needed, used, then immediately discarded (variable cleanup, scope exit, etc.)

Mnemonic is never sent to chat channels

— not during setup, not after. The agent retrieves it programmatically for derivation only.

The agent must use secure storage

appropriate to its environment. The storage mechanism must: (1) encrypt at rest, (2) require authentication to read, (3) not expose secrets in logs, shell history, or environment dumps.

Signing pipeline (how keys flow):

Secure storage (mnemonic) → derive private key (in memory) → sign transaction → discard key

Derivation paths:

First-Time Swap Configuration

The first time a user initiates a swap,

before executing

, guide them through these one-time preferences:

Transaction deadline

— how long the on-chain transaction remains valid:

Conservative:

120

seconds (better protection against sandwich attacks in volatile markets)

Standard:

300

seconds (balanced — suitable for most users)

Relaxed:

600

seconds (for slow signing workflows, e.g., hardware wallets or multi-sig)

Explain:

"A shorter deadline protects you from price manipulation, but if signing takes too long (e.g., you're away from your wallet), the transaction will fail on-chain and waste gas."

Automatic security check

— whether to audit unfamiliar tokens before swaps:

Recommended: Always check (default) — runs

security

automatically before swap

Ask each time: Prompt before each swap involving unfamiliar tokens

Skip: Never check (not recommended — risk of honeypot tokens)

Save preferences

— store in the agent's memory/config for future swaps

Remind user

they can update anytime (e.g., "update my swap settings" or "change my default deadline")

If the user declines configuration, use sensible defaults:

deadline=300

,

security=always

.

Amounts: Everything is Human-Readable

All BGW API inputs and outputs use

human-readable values

, NOT smallest chain units (wei, lamports, satoshi).

✅ Correct

❌ Wrong

--amount 0.1

(0.1 USDT)

--amount 100000000000000000

(100 quadrillion USDT!)

--amount 1

(1 SOL)

--amount 1000000000

(1 billion SOL!)

This applies to:

swap-quote

,

swap-calldata

,

swap-send

, and all

toAmount

/

fromAmount

values in responses. The

decimals

field in responses is informational only — do not use it for conversion.

Native Tokens

Use empty string

""

as the contract address for native tokens (ETH, SOL, BNB, etc.). This is a common source of errors — do not pass the wrapped token address (e.g., WETH, WSOL) when querying native token info.

Common Stablecoin Addresses

Always use these verified addresses for USDT/USDC.

Do not guess or generate contract addresses from memory — incorrect addresses will cause API errors (

error_code: 80000

, "get token info failed").

USDT vs USDT0:

Tether has begun migrating USDT to USDT0 (omnichain version via LayerZero) on some chains. On Arbitrum, the same contract address now represents USDT0 instead of legacy USDT. The contract addresses remain unchanged and work identically with the BGW API — no special handling is needed. When a user asks to swap "USDT", use the address below regardless of whether the chain has migrated to USDT0.

Common Pitfalls

Wrong chain code

Use

sol

not

solana

,

bnb

not

bsc

. See the Chain Identifiers table below.

Batch endpoints format

:

batch-token-info

uses

--tokens "sol:,eth:"

— chain and address are colon-separated, pairs are comma-separated.

Liquidity pools

The

liquidity

command returns pool info including LP lock percentage. 100% locked LP is generally a positive signal; 0% means the creator can pull liquidity.

Stale quotes

If more than ~30 seconds pass between getting a quote and executing, prices may have moved. Re-quote for time-sensitive trades.

Insufficient gas

A swap can fail silently if the wallet lacks native tokens for gas. The transaction still consumes gas fees even when it reverts. Check balance before proceeding.

Missing token approval (EVM)

On EVM chains, forgetting to approve the token for the router is the #1 cause of failed swaps. The transaction will revert on-chain and waste gas. See "EVM Token Approval" in

docs/trading.md

.

Automate the boring parts
