Multi-chain yield optimization via yield.xyz (StakeKit). An agent skill from moonpay/skills.

  • Works in 7 steps: Discover Yields → Inspect a Yield → Enter a Position → …
  • The user wants to earn yield
  • SKILL.md covers Overview, Prerequisites, Installation and Commands, plus 7 more sections
  • Calls npx, npm and git; reaches github.com and dashboard.yield.xyz; needs YIELDS_API_KEY

What it does

Yield Optimization is an agent skill from moonpay/skills. Multi-chain yield optimization via yield.xyz (StakeKit). Discover 2,988+ yield opportunities across 75+ blockchains, build deposit/withdrawal transactions with shell scripts, and sign them with a MoonPay wallet. Use when the user wants to earn yield, find the best lending or staking rate, enter/exit a position, or check portfolio balances.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Shell scripting and Banking and insurance. The repository describes itself as: Skills for AI agents to move money — on-ramps, swaps, wallets, deposits, and more via the MoonPay CLI. The licence is MIT.

When your agent uses it

  • The user wants to earn yield
  • Find the best lending
  • Enter/exit a position
  • Check portfolio balances

Example prompts

  • “/yield-optimization”

Requirements

  • Node.js
  • A credential in YIELDS_API_KEY

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Discover Yields
  2. Inspect a Yield
  3. Enter a Position
  4. Sign with MoonPay
  5. Monitor Portfolio
  6. Exit a Position
  7. Manage Rewards

What it can do on your machine

Read from SKILL.md and the folder at commit aa672ab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx
    • npm
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com
    • dashboard.yield.xyz

    Also links to:

    • docs.yield.xyz
    • npmjs.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • YIELDS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Yield Optimization loads about 1.6k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

yield.xyz — Multi-Chain Yield Optimization

Overview

yield.xyz (powered by StakeKit) aggregates 2,988+ yield opportunities across 75+ blockchains — lending, staking, vaults, restaking, and liquidity pools. The agent skill uses shell scripts to discover yields, build unsigned transactions, and sign them with your MoonPay wallet.

find-yields.sh    → discover opportunities by chain + token
enter-position.sh → build unsigned deposit transaction
mp transaction send → sign and broadcast with MoonPay wallet
check-portfolio.sh → monitor balances and pending rewards
exit-position.sh  → build unsigned withdrawal transaction

Prerequisites

bash
# curl and jq (required)
which curl jq

# MoonPay CLI for wallet + signing
npm install -g @moonpay/cli
mp login

export YIELDS_API_KEY="..."   # optional: get one at https://dashboard.yield.xyz

Installation

bash
npx clawhub@latest install yield-agent

Or manually:

bash
git clone https://github.com/stakekit/yield-agent.git ~/.openclaw/skills/yield-agent
chmod +x ~/.openclaw/skills/yield-agent/scripts/*.sh

Commands

ScriptDescription
find-yields.sh [chain] [token]Discover yields by network and token
get-yield-info.sh [yield-id]Retrieve yield schema and validator info
list-validators.sh [yield-id]List validators for staking positions
enter-position.sh [yield-id] [address] [params]Build unsigned deposit transaction
exit-position.sh [yield-id] [address]Build unsigned withdrawal transaction
manage-position.sh [yield-id] [action]Claim rewards, restake, redelegate
check-portfolio.sh [yield-id] [address]View balances and pending actions

Core Workflow

1. Discover Yields
bash
# Find USDC yields on Base
./scripts/find-yields.sh base USDC

# Find ETH staking on Ethereum
./scripts/find-yields.sh ethereum ETH
2. Inspect a Yield
bash
# Get schema and requirements before entering
./scripts/get-yield-info.sh base-usdc-aave-v3-lending

Always fetch the yield schema before executing — it specifies required params and multi-step order.

3. Enter a Position
bash
# Build unsigned deposit transaction (amounts are human-readable — "100" = 100 USDC)
./scripts/enter-position.sh base-usdc-aave-v3-lending 0xYOUR_ADDRESS '{"amount":"100"}'
# → returns unsignedTransaction JSON
4. Sign with MoonPay
bash
# Step 1: Sign the unsigned transaction
mp transaction sign \
  --wallet "yield-agent" \
  --chain base \
  --transaction '<unsignedTransaction from step 3>'
# → returns signedTransaction JSON

# Step 2: Broadcast the signed transaction
mp transaction send \
  --chain base \
  --transaction '<signedTransaction from step 1>'

For multi-step transactions, execute in stepIndex order. Sign each step exactly as returned — never modify unsignedTransaction.

5. Monitor Portfolio
bash
./scripts/check-portfolio.sh base-usdc-aave-v3-lending 0xYOUR_ADDRESS
6. Exit a Position
bash
./scripts/exit-position.sh base-usdc-aave-v3-lending 0xYOUR_ADDRESS
# → sign result with mp transaction send
7. Manage Rewards
bash
./scripts/manage-position.sh base-usdc-aave-v3-lending claim
./scripts/manage-position.sh ethereum-eth-lido-staking redelegate

Wallet Setup with MoonPay

bash
# Create a dedicated yield wallet
mp wallet create --name "yield-agent"
mp wallet retrieve --wallet "yield-agent"  # note addresses per chain

Funding Your Wallet

Buy with Fiat
bash
mp buy --token usdc_base --amount 500 --wallet <base-address> --email <email>
mp buy --token usdc_ethereum --amount 1000 --wallet <eth-address> --email <email>
mp buy --token eth_ethereum --amount 0.05 --wallet <eth-address> --email <email>
Bridge Cross-Chain
bash
# USDC on Ethereum → Base (chase higher yield)
mp token bridge \
  --from-wallet yield-agent --from-chain ethereum \
  --from-token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 \
  --from-amount 500 \
  --to-chain base \
  --to-token 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913
Bank Transfer (Large Capital)
bash
mp virtual-account create && mp virtual-account kyc submit
mp virtual-account bank-account add
mp virtual-account onramp create \
  --name "yield-onramp" --fiat usd --stablecoin usdc --chain ethereum --wallet <eth-address>
Check Balances / Withdraw
bash
mp token balance list --wallet <eth-address> --chain ethereum
mp virtual-account offramp create --amount 2000 --chain ethereum --wallet <eth-address>

Security

yield.xyz only builds unsigned transactions — your MoonPay wallet handles all signing. Keys are AES-256-GCM encrypted locally and never leave the machine. For large positions use a hardware wallet:

bash
mp wallet hardware add --name "yield-ledger"

End-to-End Workflow

  1. npx clawhub@latest install yield-agent
  2. mp wallet create --name "yield-agent"
  3. mp buy --token usdc_base --amount 500 --wallet <address> --email <email>
  4. ./scripts/find-yields.sh base USDC
  5. ./scripts/get-yield-info.sh <yield-id>
  6. ./scripts/enter-position.sh <yield-id> <address> '{"amount":"500"}'
  7. mp transaction sign --wallet "yield-agent" --chain base --transaction <unsignedTx> then mp transaction send --chain base --transaction <signedTx>
  8. ./scripts/check-portfolio.sh <yield-id> <address>
  9. mp virtual-account offramp create to withdraw earned yield
