KyberSwap Approve Skill
Manage ERC-20 token approvals for the KyberSwap router. Check current allowance, approve exact amounts, approve unlimited, or revoke approvals using Foundry's cast.
Prerequisites
- Foundry installed:
castmust be available in PATH - Wallet configured: One of the methods below (only needed for setting/revoking approvals, not for checking allowance)
- Native token for gas: Approval transactions cost gas (~46k gas for standard ERC-20)
Wallet Setup (One-Time)
⚠️ USE YOUR EXISTING WALLET MANAGEMENT FIRST ⚠️
If you or your agent already have wallet management (key management service, vault, HSM, custodial API, MPC signer, or any secure signing infrastructure), use that. Skip the examples below entirely.
The wallet options below are example setups for development and testing only. They have known security issues: plaintext password files on disk, private keys in shell environments, no access control, no audit trail, no key rotation. Do not use them with real funds in production.
Option A: Encrypted Keystore (Recommended)

swap-execute-fast
This skill should ONLY be used when the user explicitly asks for immediate, no-confirmation execution using phrases like "fast swap", "execute immediately", "swap with no confirmation", "quick swap now", "instant execute", or "skip confirmation and swap". The user must clearly indicate they want to bypass the review/confirmation step. Do NOT use this skill if the user mentions wanting to review, confirm, check, or verify before executing — use swap-build + swap-execute instead. Do NOT use this skill for general swap requests like "swap ETH to USDC" or "trade tokens" — those should go to swap-build. This skill runs a shell script that builds the swap via fast-swap.sh then immediately broadcasts the transaction. DANGEROUS - no confirmation before sending real transactions.
19swap-execute
This skill should be used when the user asks to "execute swap", "send swap transaction", "submit swap", "broadcast swap", "run the swap", "execute the trade", or wants to submit a previously built swap transaction on-chain. Uses Foundry's `cast send` to broadcast transactions. Requires swap calldata from swap-build skill output.
17swap-build
This skill should be used when the user asks to "swap-build", "build a swap transaction", "build swap calldata", "create swap tx", "swap tokens", "trade crypto", "execute a token exchange", "swap ETH to USDC", "convert tokens", or needs encoded calldata for on-chain submission. Fetches the best route and builds transaction data via KyberSwap Aggregator.
16error-handling
Handle errors when swapping tokens through KyberSwap Aggregator API
16quote
This skill should be used when the user asks to "get a swap quote", "check swap price", "compare token rates", "see exchange rates", "how much would I get for", "price check", or wants to know the expected output for a token trade. Fetches the best route from KyberSwap Aggregator across 18 EVM chains.
15zap
This skill should be used when the user asks to "zap into a pool", "add liquidity", "zap in", "provide liquidity", "LP into", "zap out", "remove liquidity from pool", "withdraw from position", "migrate position", "move liquidity", "migrate LP", "rebalance position", or wants to add, remove, or migrate liquidity in concentrated liquidity pools in one transaction. Uses KyberSwap Zap as a Service (ZaaS) API to handle token ratio calculation, swaps, and deposits in a single transaction across 13 EVM chains.
