Overview

Prophet’s smart contracts are already live on 0G Galileo. Use this guide if you need to deploy a fresh instance — for your own fork, a new environment, or mainnet deployment.
Current live deployment (0G Galileo, chain ID 16602):
  • ProphetFactory: 0xEd51e3d6Ba8914875616bBcDd9aa9D4A00B27bD4
  • LiquidityPool: 0x13AbE644693DA19f9A895C8c82Cf53879580DA8e
  • Mock USDT: 0xc2B0D2A7e858F13B349843fF87dBF4EBF9227F49
  • PositionVault: 0x89FAcA46A2782b4751F697ddFe0A0b9124Eb794E
  • PayoutDistributor: 0x238D341Bb358AC7C8Ae0A22b35897bECE97b9740

​
Prerequisites

  • Foundry installed (forge --version)
  • Deployer wallet funded with 0G gas (get from faucet.0g.ai)
  • Oracle agent wallet address (can be the same as deployer for testing)
  • Market-maker agent wallet address

​
1. Configure the Deploy Script

The deploy script lives at contracts/script/Deploy.s.sol. It reads from environment variables. Set up your contracts/.env: 
# contracts/.env
PRIVATE_KEY=0x...your_deployer_private_key
ORACLE_AGENT_ADDRESS=0x...oracle_wallet_address
MM_AGENT_ADDRESS=0x...market_maker_wallet_address
TREASURY_ADDRESS=0x...treasury_wallet_address  # where protocol fees go

# RPC endpoints
OG_TESTNET_RPC=https://evmrpc-testnet.0g.ai
OG_MAINNET_RPC=https://evmrpc.0g.ai
The foundry.toml already has the 0G network profiles: 
[rpc_endpoints]
og_testnet = "${OG_TESTNET_RPC}"
og_mainnet = "${OG_MAINNET_RPC}"

​
2. Build Contracts

Always build cleanly before deploying. This catches compilation errors early. 
cd contracts
forge build
Expected output: 
Compiling 22 files with 0.8.20
Compilation succeeded!
Check contract sizes (must all be under 24KB): 
forge build --sizes

​
3. Dry Run First

Run without --broadcast to simulate the deployment and catch any errors without spending gas: 
cd contracts
forge script script/Deploy.s.sol:DeployProphet \
  --rpc-url og_testnet \
  --legacy \
  --gas-price 3000000000 \
  -vvv
Inspect the simulation output. You should see 5 contract deployments in sequence with their constructor arguments.

​
4. Deploy to 0G Galileo Testnet

When the dry run looks correct, add --broadcast to execute: 
cd contracts
forge script script/Deploy.s.sol:DeployProphet \
  --rpc-url og_testnet \
  --broadcast \
  --legacy \
  --gas-price 3000000000 \
  -vvv
The --legacy flag is required for 0G Chain — it does not support EIP-1559 transactions. Omitting it will cause deployment to fail with a transaction type error.
The script deploys in this order (the order matters due to contract dependencies):
1

Deploy MockUSDT

Mints 10,000,000 USDT to the deployer. Only used on testnet — on mainnet, point to real USDT.
2

Deploy ProphetFactory

Constructor arguments: USDT address, oracle agent address, market-maker agent address, treasury address.
3

Deploy LiquidityPool

Constructor arguments: ProphetFactory address, USDT address, market-maker agent address.
4

Deploy PositionVault

Constructor arguments: ProphetFactory address, oracle agent address, USDT address, PayoutDistributor address (set to zero address initially — updated in step 6).
5

Deploy PayoutDistributor

Constructor arguments: ProphetFactory address, PositionVault address, oracle agent address, market-maker agent address, treasury address, USDT address.
6

Wire contracts together

Calls factory.setVaultAndDistributor(vaultAddress, distributorAddress) and positionVault.setPayoutDistributor(distributorAddress) to complete the dependency cycle.

​
5. Copy Deployed Addresses

After deployment succeeds, Foundry prints all deployed addresses. Copy them from the terminal output: 
== Return ==
ProphetFactory deployed at: 0x...
LiquidityPool deployed at: 0x...
MockUSDT deployed at: 0x...
PositionVault deployed at: 0x...
PayoutDistributor deployed at: 0x...
Update all three environment files with these addresses: 
PROPHET_FACTORY_ADDRESS=0x...
LIQUIDITY_POOL_ADDRESS=0x...
MOCK_USDT_ADDRESS=0x...
POSITION_VAULT_ADDRESS=0x...
PAYOUT_DISTRIBUTOR_ADDRESS=0x...

​
6. Regenerate Frontend ABIs

The frontend reads contract ABIs from JSON files in frontendV2/src/lib/abis/. After deploying new contracts, regenerate them from the compiled artifacts: 
# From the project root
node scripts/copy-abis.js
Or manually copy from Foundry’s output: 
cp contracts/out/ProphetFactory.sol/ProphetFactory.json frontendV2/src/lib/abis/
cp contracts/out/MarketContract.sol/MarketContract.json frontendV2/src/lib/abis/
cp contracts/out/LiquidityPool.sol/LiquidityPool.json frontendV2/src/lib/abis/
cp contracts/out/PositionVault.sol/PositionVault.json frontendV2/src/lib/abis/
cp contracts/out/PayoutDistributor.sol/PayoutDistributor.json frontendV2/src/lib/abis/

​
7. Verify Contracts on 0G Explorer

Verifying source code lets anyone read the contract on the block explorer. 0G Galileo uses a Blockscout-compatible explorer. 
forge verify-contract \
  --chain-id 16602 \
  --verifier blockscout \
  --verifier-url https://chainscan-galileo.0g.ai/api \
  <DEPLOYED_ADDRESS> \
  src/ProphetFactory.sol:ProphetFactory
Repeat for each contract. Verified contracts show a green checkmark on chainscan-galileo.0g.ai.

​
8. Fund Agent Wallets

Both agents need 0G gas to submit transactions. Get tokens from faucet.0g.ai for both wallet addresses. The market-maker agent also needs USDT in the LiquidityPool to seed markets. Transfer USDT to the LiquidityPool contract address, or call deposit() on LiquidityPool from the deployer wallet.

​
9. Start Agents

cd agent
npm run start
On startup, both agents:
  1. Verify they can connect to 0G Chain (reads current block)
  2. Verify 0G Storage connectivity (test upload/download)
  3. Scan for existing markets to catch up on missed events
  4. Begin listening for new events

  • Explorer: https://chainscan-galileo.0g.ai
  • Native token: 0G (for gas)
  • Collateral: Mock USDT at address above (6 decimals)

​
Deploying to 0G Mainnet

For mainnet deployment, change the RPC and use real USDT: 
forge script script/Deploy.s.sol:DeployProphetMainnet \
  --rpc-url og_mainnet \
  --broadcast \
  --legacy \
  --gas-price 3000000000 \
  -vvv
On mainnet, do not deploy MockUSDT. Point contracts to the official USDT address on 0G Chain. Ensure USDT addresses use 6 decimal places throughout.
The mainnet compute provider for DeepSeek V3 is at 0x1B3AAe... — update COMPUTE_PROVIDER_ADDRESS in agent/.env accordingly.
