# Abstract Onboard

Everything an AI agent needs to operate on Abstract (ZK Stack L2).

## 🚀 New Agent? Start Here

```bash
# Check if you're ready to operate
node scripts/quick-start.js check <your-wallet-address>

# Or get the full setup guide
node scripts/quick-start.js
```

## Quick Start

### Create Abstract Global Wallet (AGW)
AGW is a smart contract wallet that earns XP on Abstract. Essential for agents!

**⚠️ CRITICAL: Understand the 3 layers first:**
```
Private Key → EOA (signer) → AGW (smart contract wallet)
```

**The correct funding flow:**
```
1. Fund EOA with small ETH (for gas)
2. Create/deploy AGW (EOA pays gas for first tx)
3. Fund AGW with your main balance
4. Everything runs through AGW from now on
```

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

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

**⚠️ Version Warning:** Different `agw-client` versions may compute different AGW addresses! Always pin your version. See `references/agw.md` for details.

### 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
```

### DEX Trading (Kona & Aborean)

Abstract has multiple DEXs. Use the protocol-specific scripts for best results:

```bash
# Kona Finance (V2) - USDC → ETH
export WALLET_PRIVATE_KEY=0x...
node scripts/swap-kona.js

# Aborean (Velodrome-style) - when router is available
node scripts/swap-aborean.js

# Generic Uniswap V2
node scripts/swap-uniswap-v2.js
```

See `references/dex.md` for contract addresses and supported pools.

### Myriad Prediction Markets

Trade on Myriad Markets — the largest prediction market on Abstract (415K+ users, $100M+ volume).

```bash
# List open markets
node scripts/myriad-trade.js list

# Get market details
node scripts/myriad-trade.js info <marketId>

# Buy shares (place a prediction)
export WALLET_PRIVATE_KEY=0x...
node scripts/myriad-buy-direct.js <marketId> <outcomeId> <amount>

# Example: $1 USDC.e on "Yes" for market 765
node scripts/myriad-buy-direct.js 765 0 1
```

See `references/myriad.md` for contract addresses, ABI details, and token info.

### 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
```

### Mint NFT
```bash
# Deploy SimpleNFT.sol first, then mint
export WALLET_PRIVATE_KEY=0x...

# Mint to existing contract
node scripts/mint-nft.js --contract 0x... --image QmIPFShash --to 0xRecipient --name "My NFT"
```

See `references/SimpleNFT.sol` for a basic NFT contract template.

### USDC Operations
```bash
# Check USDC balance
node scripts/usdc-ops.js balance <wallet>

# Transfer USDC
export WALLET_PRIVATE_KEY=0x...
node scripts/usdc-ops.js transfer <to> <amount>

# Approve spender
node scripts/usdc-ops.js approve <spender> <amount>

# Check allowance
node scripts/usdc-ops.js allowance <owner> <spender>
```

### Estimate Gas
```bash
# Get current gas prices
node scripts/estimate-gas.js

# Estimate transfer cost
node scripts/estimate-gas.js transfer <to> <amount>

# Estimate deployment cost
node scripts/estimate-gas.js deploy <bytecodeSize>
```

### Watch Events
```bash
# Watch new blocks
node scripts/watch-events.js blocks

# Watch ETH transfers to/from wallet
node scripts/watch-events.js transfers <wallet>

# Watch ERC20 transfers
node scripts/watch-events.js erc20 <token> <wallet>

# Watch contract events
node scripts/watch-events.js contract <address>
```

### Testnet Setup
```bash
# Get faucet instructions
node scripts/testnet-setup.js faucet

# Check testnet balance
node scripts/testnet-setup.js check <wallet>

# Verify testnet setup
node scripts/testnet-setup.js verify <wallet>
```

## ⚠️ CRITICAL: Contract Deployment

Abstract is a zkSync-based chain. Standard EVM deployment methods DON'T WORK.

### What WORKS ✅
```javascript
// Use zksync-ethers (NOT viem, NOT standard ethers)
const { ContractFactory } = require("zksync-ethers");
const factory = new ContractFactory(abi, bytecode, wallet);
const contract = await factory.deploy(args);

// ALWAYS verify bytecode after deploy
const code = await provider.getCode(address);
if (code === '0x') throw new Error("Deploy failed!");
```

### What DOESN'T WORK ❌
```javascript
// DON'T use viem's deployContract
await walletClient.deployContract({...}); // Returns success but NO BYTECODE

// DON'T use standard ethers ContractFactory
// DON'T trust transaction success alone
```

### Deployment Checklist
- [ ] Compiled with zksolc (not standard solc)
- [ ] Using `zksync-ethers` ContractFactory
- [ ] Verify `eth_getCode != 0x` after deploy
- [ ] Test contract functions before sending tokens

## 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
4. **Deploy succeeds but no bytecode** → Use zksync-ethers, not viem
5. **Tokens sent to empty address** → Always verify bytecode first!

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) - PIN THE VERSION!
# Different versions compute different AGW addresses
npm install @abstract-foundation/agw-client@1.10.0
```

**⚠️ agw-client version warning:** Newer versions may use different factory contracts, computing different AGW addresses for the same EOA. If you change versions, verify your AGW address hasn't changed before sending funds!
