Mock & Dependency Contracts

Mock and infrastructure contracts deployed on the BattleChain testnet

BattleChain testnet includes mock versions of common mainnet dependencies and real infrastructure contracts so you can deploy your exact production bytecode — only swapping constructor parameters like oracle addresses.

Mock Chainlink Price Feeds

These MockV3Aggregator contracts implement the same interface as Chainlink price feeds. Contracts that consume latestRoundData() or getRoundData() on mainnet can point at these addresses on testnet without code changes.

All feeds use 8 decimals, matching Chainlink's standard for USD pairs.

Updating Prices

To set ETH/USD to $2,000:

cast send 0xAA72F0168eE17aA93098eC6ECf2EEe72B46aca19 \
  "updateAnswer(int256)" 200000000000 \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

The value 200000000000 is 2000 * 1e8 (8 decimals).

Test Tokens

Mintable ERC-20 tokens for protocols that need token dependencies (stablecoins, WBTC, LINK, etc.). Anyone can mint — no faucet required.

Minting Tokens

To mint 1,000,000 USDC to yourself:

cast send 0xb9bEab76Db81BdF8c863f2cA648dA8d3bB5CB1EE \
  "mint()" \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

To mint a specific amount to any address:

cast send 0xb9bEab76Db81BdF8c863f2cA648dA8d3bB5CB1EE \
  "mint(address,uint256)" 0xYOUR_ADDRESS 5000000000 \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

The value 5000000000 is 5000 * 1e6 (USDC has 6 decimals).

Mock Venus Protocol

A mock Venus lending protocol deployment with a Comptroller and five vToken markets. Implements the same Compound-style interface (supply, borrow, redeem, repay) so contracts that integrate with Venus on mainnet work on testnet without code changes.

All markets are listed with a 0.75 collateral factor. The mock Comptroller always reports accounts as healthy with 1M liquidity — it does not enforce real collateral checks.

Deployed Addresses

The vToken markets use the test tokens as their underlying assets. vBNB uses native ETH.

Interface

Supplying and Borrowing

To supply 1,000 USDC to vUSDC (approve first, then mint):

cast send 0xb9bEab76Db81BdF8c863f2cA648dA8d3bB5CB1EE \
  "approve(address,uint256)" \
  0x5982EC7f7B42F5490695EE14991aA35E6F6258bD 1000000000 \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

cast send 0x5982EC7f7B42F5490695EE14991aA35E6F6258bD \
  "mint(uint256)" 1000000000 \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

To supply native ETH to vBNB:

cast send 0x96360B56BC70B09eb6F3870B3f48AFeA32e60EeE \
  "mint()" \
  --value 1ether \
  --rpc-url $BATTLECHAIN_RPC_URL \
  --private-key $PRIVATE_KEY \
  --legacy

Mock Uniswap V3

A mock Uniswap V3 deployment with the core factory, swap router, and position manager. Contracts that integrate with Uniswap V3 on mainnet can point at these addresses on testnet without code changes.

Deployed Addresses

Use with the test tokens above (WETH, USDC, DAI, etc.) to create pools and test swap logic.

Mock Uniswap V4

A mock Uniswap V4 PoolManager deployment.

Deployed Addresses

Mock Euler V2

A mock Euler V2 deployment with the Ethereum Vault Connector (EVC) and two lending vaults.

Deployed Addresses

The vaults use the test tokens as their underlying assets (USDC and WETH respectively).

Mock Chainlink CCIP

A mock Chainlink CCIP router for testing cross-chain messaging and token transfers.

Deployed Addresses

Safe (Gnosis Safe)

The full Safe smart account infrastructure is deployed on BattleChain testnet. These are real Safe contracts (not mocks) — protocols that use Safe multisigs for governance, treasury, or access control can use the same addresses and deployment patterns as on mainnet.
