What its author says it does

Copied from the file, not written here

Use this skill to build and sanity-check unsigned DeFi transaction payloads (to/data/value/chain) for swaps, lending, staking, and bridging.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

DeFi Transaction Builder

Purpose

Prepare transaction plans and calldata for user review. This skill is strictly for unsigned payload generation and validation.

Use this skill when

  • The user wants transaction parameters for swaps, supply/borrow, staking, claiming, or bridging.
  • The user requests calldata formatting or simulation-ready bundles.

Never do

  • Never ask for private keys, seed phrases, or wallet exports.
  • Never sign or broadcast transactions.
  • Never omit warnings for network, slippage, or allowance risk.

Workflow

  1. Confirm intent and constraints:
    • Chain/network
    • Token amounts and units
    • Slippage and deadline
  2. Build the unsigned transaction payload(s).
  3. Validate shape and safety checks using scripts/validate_tx_bundle.py.
  4. Output a simulation-first transaction plan with human-readable checks.

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
