Smart Contracts

BV-7X uses several on-chain contracts across Base mainnet and Base Sepolia testnet.

$BV7X Token

Property	Value
Name	BV7X
Chain	Base

MultiRewards Staking — Testnet (live)

Property	Value
Contract	0xFB47CB11C72b551d0101fa8BCdB7a7fbCb11CA9B
Chain	Base Sepolia (testnet)
Solidity	0.8.28
Access Control	Ownable2Step
Test Coverage	49/49 tests passing · 98.48% stmts / 83.33% branch

MultiRewards allows staking $BV7X to earn multiple reward tokens simultaneously.

Test tokens:

• mBV7X: 0xC67f025175f5f5b09B616E1a2F6A381E54c6fc3d

• mWETH: 0x3f548086F2E7b4f9Dc92da1cED531Bb0e8a27d93

Note: The contract is not upgradeable. Reward tokens are permanently committed once added — there is no recoverUnusedRewards function. recoverERC20 reverts on the staking token and on any reward token, so user funds cannot be drained by the owner. The rewardsDuration argument passed to addReward is also permanent — this port does not include a setRewardsDuration function, so the duration cannot be changed for the life of the contract.

MultiRewards Staking — Base mainnet (pending)

Production deployment is staged but not yet live. Deploys via scripts/deploy-mainnet.js against the existing immutable BV7X token at 0xD88FD4a11255E51f64f78b4a7d74456325c2d8dC. Owner = deployer EOA in v1 (no Safe). See mainnet-checklist.md for the full deploy + operations runbook.
