Yield Optimization

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

# 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

npx clawhub@latest install yield-agent

Or manually:

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

Commands

| Script | Description | |--------|-------------| | 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

# 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

# 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

# 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

# Step 1: Sign the unsigned transaction
mp transaction sign \
  --wallet "yield-agent" \
  --chain base \
  --transaction ''
# → returns signedTransaction JSON

# Step 2: Broadcast the signed transaction
mp transaction send \
  --chain base \
  --transaction ''

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

5. Monitor Portfolio

./scripts/check-portfolio.sh base-usdc-aave-v3-lending 0xYOUR_ADDRESS

6. Exit a Position

./scripts/exit-position.sh base-usdc-aave-v3-lending 0xYOUR_ADDRESS
# → sign result with mp transaction send

7. Manage Rewards

./scripts/manage-position.sh base-usdc-aave-v3-lending claim
./scripts/manage-position.sh ethereum-eth-lido-staking redelegate

Wallet Setup with MoonPay

# 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

mp buy --token usdc_base --amount 500 --wallet  --email 
mp buy --token usdc_ethereum --amount 1000 --wallet  --email 
mp buy --token eth_ethereum --amount 0.05 --wallet  --email 

Bridge Cross-Chain

# 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)

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 

Check Balances / Withdraw

mp token balance list --wallet  --chain ethereum
mp virtual-account offramp create --amount 2000 --chain ethereum --wallet 

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:

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 --email
4. ./scripts/find-yields.sh base USDC
5. ./scripts/get-yield-info.sh
6. ./scripts/enter-position.sh '{"amount":"500"}'
7. mp transaction sign --wallet "yield-agent" --chain base --transaction then mp transaction send --chain base --transaction
8. ./scripts/check-portfolio.sh
9. mp virtual-account offramp create to withdraw earned yield
