abstract-onboard – OpenClaw Skill

---

name: abstract-onboard description: Deploy smart contracts and bridge assets to Abstract (ZK Stack L2). Use when an agent needs to deploy contracts on Abstract, bridge ETH/tokens to Abstract, trade/swap tokens, check balances, transfer assets, or interact with Abstract mainnet. Covers zksolc compilation, Hardhat deployment, Relay bridging, DEX trading, and key contract addresses.

Abstract Onboard

Everything an agent needs to operate on Abstract.

Quick Start

Create Abstract Global Wallet (AGW)

AGW is a smart contract wallet that earns XP on Abstract. Essential for agents!

export WALLET_PRIVATE_KEY=0x...
node scripts/create-agw.js

Your EOA becomes the signer, AGW is a separate smart contract address.

Check Balances

node scripts/check-balances.js <wallet> all

Bridge ETH to Abstract

export WALLET_PRIVATE_KEY=0x...
node scripts/relay-bridge.js --from base --amount 0.01

Deploy a Contract

export WALLET_PRIVATE_KEY=0x...
node scripts/deploy-abstract.js ./artifacts/MyContract.json "constructor-arg"

Transfer Tokens

export WALLET_PRIVATE_KEY=0x...
node scripts/transfer.js --to 0x... --amount 0.01           # ETH
node scripts/transfer.js --to 0x... --amount 100 --token USDC  # Token

Swap Tokens

export WALLET_PRIVATE_KEY=0x...
export DEX_ROUTER=0x...  # Set DEX router address
node scripts/swap-tokens.js --from ETH --to USDC --amount 0.01

Call Any Contract

# Read
node scripts/call-contract.js --address 0x... --abi ./abi.json --function balanceOf --args 0x1234

# Write
export WALLET_PRIVATE_KEY=0x...
node scripts/call-contract.js --address 0x... --abi ./abi.json --function transfer --args 0x1234,100 --write

Common Issues

1. Gas estimation fails → Use Hardhat, not foundry-zksync
2. Compiler errors → Use Solidity 0.8.x with zksolc
3. TX stuck → Check gas price, verify on abscan.org

See references/troubleshooting.md for detailed solutions.

Dependencies

# Core dependencies
npm install ethers zksync-ethers viem

# For contract deployment
npm install @matterlabs/hardhat-zksync
