BNB

Assist with BNB Chain transactions, BEP-20 tokens, gas fees, and cross-chain transfers.

Security Scan

This is an instruction-only skill that provides general, coherent guidance about BNB Chain, and it does not request credentials, install software, or instruct the agent to access local secrets or external endpoints beyond public network/rpc/explorer URLs.

Purpose & Capability

The name and description (BNB/BNB Chain guidance) match the SKILL.md content, which is focused on transactions, tokens, gas, wallets, bridges, and security practices. There are no unrelated required binaries, env vars, or install steps.

Instruction Scope

SKILL.md contains static guidance and recommended public endpoints (e.g., bsc-dataseed.binance.org, bscscan.com). It does not instruct the agent to read local files, access unspecified environment variables, collect secrets, or transmit user data to unknown endpoints.

Install Mechanism

No install spec or code files are present; the skill is instruction-only so nothing is written to disk or downloaded during install.

Credentials

The skill declares no environment variables, credentials, or config paths. There are no disproportionate credential requests relative to the stated purpose.

Persistence & Privilege

always:false and no indications of modifying agent/system configuration or demanding persistent presence. Autonomous invocation is allowed by platform default but the skill itself does not request elevated persistence.

Assessment

This skill is essentially a static reference about BNB Chain and appears internally consistent. Before using it for real transactions, remember: the skill does not and cannot access your wallet or keys (you must never share them), verify contract addresses and bridge endpoints independently (use official explorers and project sites), prefer hardware wallets for large amounts, and treat any financial guidance conservatively — the skill provides general information, not transaction execution or custody.

Network Clarity (Critical)

• "BNB Chain" is the main smart contract chain — formerly Binance Smart Chain (BSC)
• "BNB Beacon Chain" was for staking — deprecated, merged into BNB Chain
• BEP-20 tokens on BNB Chain — equivalent to ERC-20, EVM compatible
• Same address format as Ethereum — 0x... addresses work on both
• DIFFERENT networks — sending to wrong network loses funds

BNB Token

• Native gas token for BNB Chain — needed for all transactions
• Also available as BEP-2 (legacy), ERC-20 (Ethereum), and other wrapped versions
• BNB on Binance exchange can be withdrawn to multiple networks — choose carefully
• Burning mechanism reduces supply — quarterly burns based on trading volume

Gas and Fees

• EVM compatible gas model — same as Ethereum but cheaper
• Gas prices typically 3-5 gwei — much lower than Ethereum
• Standard transfer ~21,000 gas — costs fraction of a cent
• Complex DeFi transactions cost more — but still very cheap
• Fast block time (3 seconds) — quick confirmations

BEP-20 Tokens

• Same interface as ERC-20 — all ERC-20 tooling works
• Approve + transfer pattern — same as Ethereum
• Many tokens have same name as Ethereum versions — but different contracts
• Verify contract address on bscscan.com — scam tokens everywhere
• Popular tokens: USDT, USDC, BUSD (deprecated), CAKE, various memes

Cross-Chain Transfers

• Binance exchange supports direct withdrawal to BNB Chain — easiest method
• Bridges: cBridge, Multichain, Stargate — verify bridge reputation
• BNB Chain ↔ Ethereum requires bridge — not same network despite same addresses
• opBNB is L2 on BNB Chain — even lower fees, different RPC
• Wrapped assets need unwrapping — bridged ETH is not native ETH

DeFi Ecosystem

• PancakeSwap is largest DEX — similar to Uniswap
• Venus for lending/borrowing — similar to Aave
• Lower TVL than Ethereum DeFi — but still significant
• Higher rug pull risk — less auditing culture
• Verify contracts before interacting — bscscan shows verification status

Wallet Configuration

• MetaMask works natively — add BNB Chain network
• Chain ID: 56 — RPC: https://bsc-dataseed.binance.org
• Block explorer: bscscan.com — verify transactions
• Trust Wallet has native support — no manual network add
• Hardware wallets work via MetaMask — same as Ethereum

Staking

• Stake BNB with validators — earn staking rewards
• Minimum stake varies by validator — typically 1 BNB minimum
• Unbonding period: 7 days — funds locked during unstaking
• Slashing risk exists — choose reliable validators
• Liquid staking options: stkBNB, ankrBNB — maintain liquidity while staking

Common Scams

• "USDT" with wrong contract — verify against official addresses
• Honeypot tokens — can buy but not sell
• Fake PancakeSwap sites — always verify URL
• Airdropped tokens you didn't request — often scam triggers
• "Validators" asking for private keys — never share

Common Issues

• "Insufficient funds for gas" — need BNB for gas, not just tokens
• Wrong network — ETH sent to BNB Chain address (same address, different chains)
• High slippage on DEX — low liquidity tokens
• Transaction pending — try increasing gas price
• Contract interaction failed — check approval and balance

Security

• Same security model as Ethereum — private key = full access
• Revoke unused approvals — bscscan.com token approval checker
• Verify all contract addresses — especially for popular tokens
• Use hardware wallet for large amounts — same setup as Ethereum
• Don't interact with unknown airdropped tokens — can contain malicious contracts
