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!
```bash
export WALLET_PRIVATE_KEY=0x...
node scripts/create-agw.js
```
Your EOA becomes the signer, AGW is a separate smart contract address.

### Check Balances
```bash
node scripts/check-balances.js <wallet> all
```

### Bridge ETH to Abstract
```bash
export WALLET_PRIVATE_KEY=0x...
node scripts/relay-bridge.js --from base --amount 0.01
```

### Deploy a Contract
```bash
export WALLET_PRIVATE_KEY=0x...
node scripts/deploy-abstract.js ./artifacts/MyContract.json "constructor-arg"
```

### Transfer Tokens
```bash
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
```bash
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
```bash
# 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

```bash
# Core dependencies
npm install ethers zksync-ethers viem

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

# For AGW (Abstract Global Wallet)
npm install @abstract-foundation/agw-client
```
