Bitget Wallet Skill

API Overview

How to handle tasks:

Primary sources: Use the Scripts section in this SKILL and the files under docs/ to decide which commands to run and how. Scripts lists each Python CLI with purpose, subcommands, and when to use them; docs/swap.md, docs/wallet-signing.md, docs/market-data.md, etc. describe flows and domain rules.
Run commands as documented: Execute the script invocations shown in Scripts (e.g. python3 scripts/bitget_agent_api.py ..., python3 scripts/order_sign.py ...). For swap, balance, wallet, and signing, follow the flows in docs/swap.md and docs/wallet-signing.md.

Before starting a new swap - two mandatory pre-checks:

Balance check (required): Run get-processed-balance to verify the wallet has enough fromToken balance for the intended swap amount. Include native token ("") to check gas availability. If fromToken balance < fromAmount, inform the user of the shortfall and do not proceed. Gas mode decision: If native token balance is sufficient for gas → use --feature user_gas (preferred). If native token balance is near zero → use --feature no_gas (gasless, gas deducted from fromToken; requires swap amount ≥ ~$5 USD — below this threshold the API only returns user_gas). This choice must be passed to confirm.
```
python3 scripts/bitget_agent_api.py get-processed-balance --chain <fromChain> --address <wallet> --contract "" --contract <fromContract>
```
Token risk check (required): Run check-swap-token for the intended fromToken and toToken. If error_code != 0, show msg and stop. If for any token data.list[].checkTokenList is non-empty, show the tips content to the user and let them decide whether to continue. If the toToken (swap target) has an item with waringType equal to "forbidden-buy", do not proceed with the swap and warn the user that this token cannot be used as the swap target.
```
python3 scripts/bitget_agent_api.py check-swap-token --from-chain ... --from-contract ... --from-symbol ... --to-chain ... --to-contract ... --to-symbol ...
```

See Scripts for full command details and docs/swap.md for the complete flow.

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.

First-use version check (at most once every 7 days):

Check the installed version from frontmatter above.
Fetch the latest CHANGELOG from https://raw.githubusercontent.com/bitget-wallet-ai-lab/bitget-wallet-skill/main/CHANGELOG.md.
Compare with the installed version.

If a new version is available, inform the user (installed vs latest, one-line changes, security-related yes/no) and ask "Upgrade? [yes/no]". If the user confirms, re-install the skill from the main branch and replace all local skill files; then re-read SKILL.md. Post-upgrade: diff old/new bitget_agentapi.py, flag new endpoints/deps/credentials, and run platform security audit if applicable.

If versions match: Proceed normally. Check frequency: at most once every 7 days.

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

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.

Derivation paths:

Chain	Path	Curve
EVM (ETH/BNB/Base/...)	`m/44'/60'/0'/0/0`	secp256k1
Solana	`m/44'/501'/0'/0'`	Ed25519 (SLIP-0010)
Tron	`m/44'/195'/0'/0/0`	secp256k1

Amounts: human-readable only

All BGW API amount fields use human-readable values, not smallest units (wei, lamports, token decimals). In the swap flow, fromAmount (and toAmount, etc.) must be the human-readable number (e.g. 0.01 for 0.01 USDT). Do not convert to token decimals or wei/lamports. Applies to quote, confirm, makeOrder, and all toAmount/fromAmount in responses. The decimals field in responses is informational only.

Native tokens and addresses

Use empty string "" as the contract address for native tokens (ETH, SOL, BNB, etc.). Do not use wrapped token addresses (e.g. WETH, WSOL) for native.

Common Stablecoin Addresses

Always use these verified addresses for USDT/USDC. Do not guess or generate contract addresses from memory - incorrect addresses cause API errors (error_code: 80000, "get token info failed").

USDT vs USDT0: On some chains Tether has migrated to USDT0 (omnichain). The same contract addresses work; use the address below for "USDT" regardless.

Chain (code)	USDT (USDT0)	USDC
Ethereum (`eth`)	`0xdAC17F958D2ee523a2206206994597C13D831ec7`	`0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48`

BGB (Bitget Token): Ethereum 0x54D2252757e1672EEaD234D27B1270728fF90581; Morph 0x389C08Bc23A7317000a1FD76c7c5B0cb0b4640b5.

For other tokens, use token-info or a block explorer to verify the contract address before calling swap endpoints.

Common Pitfalls

Chain code: Use sol not solana, bnb not bsc. See Chain Identifiers below.
Batch format: e.g. batch-token-info uses --tokens "sol:<addr1>,eth:<addr2>" (chain:address, comma-separated).
Stale quotes: Re-quote if more than ~30 seconds before execute; prices may have moved.
Insufficient gas: Swap can fail if the wallet lacks native token for gas. Check balance before proceeding.
Token approval (EVM): ERC-20 must be approved for the router; see "EVM Token Approval" in docs/swap.md.
Wallet before balance/swap: If no wallet is configured, guide the user through First-Time Wallet Setup (see Wallet Domain Knowledge above).
Script usage: Use CLI commands from this SKILL (e.g. bitget_agent_api.py, order_sign.py).
Key security: Derive private keys from mnemonic on-the-fly, pass to order_sign.py --private-key, discard immediately after signing. Never store keys or output mnemonic/keys to chat.
Human-readable amounts: Pass fromAmount etc. as user-facing numbers (e.g. 0.01), not wei/lamports/decimals.
Security: Mnemonic and private keys must never appear in conversation, prompts, or any output. Only mnemonic file path and derived addresses may be in context.

Chain Identifiers

Swap-supported chains (7):

Chain	ID	Code

Safety Rules

Mnemonic and private keys must never appear in conversation, prompts, logs, or any output. Only derived addresses may be stored in context or shown. Private keys are derived from mnemonic in secure storage, used for signing, and immediately discarded.
For large trades, always show the quote first and ask for user confirmation.
Present security audit results before recommending any token action.
